Seven Months Later…

I realize it’s getting repetitive for me to start every post with an apology that it’s been so long since I posted, and an excuse that it’s hard to find time to write thoughtful posts when you have both a job and a child. I’d like to lead off with something more interesting, but it’s hard to find time to write thoughtful introductory paragraphs when you have both a job and a child. (Hats off to those of you who have already been doing this for years. I can see why most/all of you don’t have puzzlehunt blogs.)

Last time I posted here, it was “Part 1” of my Mystery Hunt recap, and you’ll notice this isn’t Part 2. I had intended to spend Part 2 talking about specific puzzles, and I had a list of the puzzles I was going to write about. But then in a conversation about the absence of Mark Halpin’s Labor Day puzzle suite last year (and how much I missed it), someone said something along the lines of, “Well, you should definitely solve Trickster Tales!” So I printed that puzzle and decided I should solve it before writing Part 2… and then I didn’t solve it… and then I still didn’t solve it… and I still haven’t solved it seven months later, in a future where half the puzzle titles I jotted down are now unfamiliar. So Mark Halpin stole your Part 2 post, folks. I’ll just say there were a bunch of fun puzzles I solved when I was able to focus on solving, and I hope we figure out a plan for 2023 that allows us to maintain that focus for longer periods of time.

Rather than the expected Mystery Hunt follow-up post, I’m checking in here to touch on a variety of topics, both so I can weigh in on them, and also so that the next time I post, I don’t have the pressure of writing my first post in seven months. Unless I don’t post anything until March. Which is entirely likely.

* These days I’m not finding much/any time to construct puzzles or write articles about them, but I’m still solving everything I can! For Huntinality 2.0, we expanded our smallish team from last year to a larger Mystik-Spiral-Alice-Shrugged mashup team, and that’s becoming a fun dynamic to solve under once a year. I attempted to solve both Edric hunts (Truzzle and Puzzle) mostly solo, and I enjoyed portions of them but didn’t make it to the end of either; in a way, having them so close together made neither demand as much focus, and I lost momentum at some point during both. I did finish REDDOTHunt (with a Mystik Spiral team under Mystsick Spir-Ill, since I was getting over a cold), and that included Manga, which might be my favorite hunt puzzle I’ve encountered this year. I mostly came here just to link to it, and I was dismayed to find that the REDDOT site seems to be down, so that doesn’t appear to be possible. But if you can find it, you should really solve it. It’s very artfully presented, and it has fun stuff to do right from the beginning, a fantastic aha, AND a jaw-dropping finale.

* I’m really looking forward to two upcoming hunts that are on my wavelength in terms of difficulty. The Galactic Puzzle Hunt is happening on the second weekend that my family is visiting Cape Cod. Since a fiendishly difficult puzzlehunt is more my jam than beach days, I’ve received clearance to drop everything and focus on GPH on Friday night, though Saturday I’ll lose a lot of time to packing/travel. If Saturday is necessary… after all, it’s a one-hour exam, what could go wrong? And then the weekend after (while Galactic is still technically in progress, though I hope Killer Chicken Bones will be done by then), it’s Cross Purposes, the return of Mark Halpin’s Labor Day puzzles after a one-year hiatus. You may remember Mark as the guy who stole your Part 2 post, but solve his puzzles anyway… These suites look P&A-length at a glance, but the puzzles themselves tend to put up much more of a fight. This should be a nice last hurrah before I disappear back into teaching for the fall semester. (I’d also be looking forward to Teammate Hunt, the sequel to my favorite online hunt of last year, but I hear they’re doing it in January this year.)

* Speaking of P&A, in the last issue Foggy mentioned that he intends to wrap up the magazine some time after its 100th issue. I understand and respect that decision… I can’t even write a blog post every few months, so it continues to boggle my mind that Foggy can produce a one-round hunt PLUS extra puzzles every two months like clockwork, along with a Puzzle Boat arguably longer than all of the issues for that year combined. I can understand the desire to focus on Puzzle Boat and/or do something else to keep things fresh. Of course, after repeatedly wondering when my top ten streak (which goes back to Issue 1) will come to an end, now I feel an intense urge to make it through the end of the run. We’ll see.

* Finally, there’s been news in MIT circles recently that MIT is moving away from their philosophy of being an “open campus.” For anyone who hasn’t visited the Institute (my undergrad alma mater), the academic buildings, many of which are interconnected, are open by default to public visitors, so anybody with a pulse could walk down the Infinite Corridor (which in some cases is the most effective way to get from some points to others in Cambridge, especially if it’s raining). During the COVID era, access was much more controlled, presumably to facilitate a vaccinated campus. I’d assumed that card access was simply added to locked doors, but I’ve now been told by friends who have been on campus that there are turnstiles, so a person can’t simply escort another random friend into a locked building. I bring all of this up because MIT has quietly announced that they are permanently shifting to this “closed campus” model; even after COVID, if that’s a thing, the main campus buildings seem like they will continue to be turnstiled and limited to people with MIT credentials and registered visitors.

This philosophical shift is significant for the MIT community as a whole (I know a petition was in draft form last time I checked, and I intend to sign it and circulate it), but in the context of this blog, the obvious issue is relevance to Mystery Hunt. At press time I have no idea if the 2023 Hunt is intended to be in person, and I had already heard many people speculate that it might never be again, but certainly this decision complicates a theoretical future Hunt that would occur on campus and be open to all. There are a lot of unknowns that affect potential access logistics. For example: (1) Do alumni IDs (which exist) grant campus access? (2) There is a process for students/faculty to register visitors… how many visitors can they register and for what purpose? (3) There is a process for events to register participants (or more specifically, give participants the opportunity to register themselves)… how many participants can they register and for what purpose? It seems clear that MIT is now going to be aware of exactly who is participating in an on-campus Hunt, and who they will allow is an open question.

With all that in mind, I’ve seen a few social media posts that this is likely the death of Mystery Hunt (or more diplomatically, of “Hunt as we know it”). I get a bit triggered by those posts, because when I was a Mystery Hunt existed in a form that would have had little trouble operating under the Institute’s radar. This is not to imply it was a secret, but it would likely not have set off any alarm bells. Hunt is MUCH larger now, both in terms of puzzle scope and participants, but that doesn’t mean that if the modern version becomes infeasible, it can’t go back to its roots. Maybe Mystery Hunt will always be online. Maybe it will get much smaller. Maybe the administration will give some latitude and let some people, or a lot of people, in for the weekend. We don’t really know, but my vote, regardless of how it affects me in the end, is that people let the MIT Puzzle Club determine what’s best for Hunt. It’s easy to snipe from the outside, especially if you’ve never constructed, but Mystery Hunt is and continues to be an MIT event, and the only reason it exists and receives MIT resources is the service it provides to the people already on campus. If you want to start your own non-MIT event, be my guest (lots of people have online over the last few years), and if you want to keep participating in Hunt if the opportunity arises, and that opportunity arises, by all means participate. But if you’re in a conversation with me, and you consider yourself to have ownership of the event because you’ve been an invited guest for so long, expect me to raise my voice.

Teammate is the third construction team in a row to have to captain a Hunt in these treacherous waters… I think the first two did an admirable job (even if online Mystery Hunts have turned out not to be my cup of tea) and I have a lot of faith in this year’s team to continue the streak.

2022 MIT Mystery Hunt, Part 1: The Big Picture and the Small Child

(This is a recap/review of the 2022 MIT Mystery Hunt, which happened this month. Puzzles and solutions can currently be found here. This recap may contain spoilers.)

My Mystery Hunt posts this year are going to be weird, because this was a weird Hunt… not that Palindrome’s Hunt was weird (apart from the sense that the past two virtual Hunts have been weird in the grand scheme of Mystery Hunts), but that my personal Hunt experience was weird. Forgive me if the first few paragraphs of this sound like they belong in a parenting blog… but becoming a parent is something many people go through and thus many puzzlehunt enthusiasts go through (plenty of my Setec teammates have kids of their own), and so maybe this will still be relatable to some of you.

My son Simon, who’s a little over ten months old now, started day care the Monday before Hunt. We are extremely fortunate in that we didn’t have to bring him in until now; my wife and I are both college faculty, and when our son was born, she had the remainder of the spring off from teaching, and then I was off in the fall. We are less fortunate in that just before day care started, he started experiencing separation anxiety for the first time… after 9+ months of barely being willing to be held, he now frequently grabs our hands and wants to be picked up. Predictably, he has not been fond of day care so far, and as a result he’s been cranky even at home and even less comfortable being away from us, even at home.

Our Mystery Hunt plan was to have a couple of squads of helpful relatives (Jackie’s mom, and my brother and his wife) babysit in shifts, with Simon staying in the house where all of the appropriate baby resources were, so that Jackie and I could do as much hunting as possible downstairs. As you can imagine from the context above, babysitting did not go as well as we hoped, and he generally screamed when we both left the room. On top of that he didn’t sleep particularly well. And while Jackie very nobly and generously took on more of the baby-wrangling than normal, she couldn’t do it all, so there was much less of us both solving than I would have liked, and also more time off from solving myself than I would have liked.

With all that in mind, while I undoubtedly still spent most of my weekend puzzle-solving, I was almost certainly more distracted than I’ve been at any other Mystery Hunt, and it all just felt… strange. For me, Hunt has always been a delicate balance of getting food fast and finding just enough sleep to be rested and maximize my puzzle contributions to my team, and when you start poking holes in both the sleep and solving, especially at times you can’t predict, both suffer. Not only did I feel less useful to my team than usual, but I also felt like a complete physical wreck by Sunday evening between the sleep deprivation and the hunching over a laptop in a cold basement. Optimistically this is peak difficulty, as next year I really hope we’re back at MIT, and even if we’re not, we’ll probably be in a better position to have Simon cared for at a different location for a few days. But given the confluence, I definitely don’t feel like I gave this Hunt the full attention it deserved, and my experience was unavoidably tainted as a result.

But other than that, Mrs. Lincoln, how was the play? Quite good, as far as I can tell. Much like Plane 1 Plane 2 Plane 3 Galactic Trendsetters Plane 4 Plane 6 Plane 5 (come on, you had one job) last year, I think Palindrome created and ran an excellent Hunt despite difficult constraints, though also like last year, I have my own nitpicks. In this post, I’ll run through some of the positives and negatives of the Hunt as a whole (keeping in mind, as always, that criticism shouldn’t be parsed as a lack of gratitude, but rather a conversation starter to help Hunt continue to evolve), and I plan to write a second post about individual puzzles that I found memorable.

As I do when I solicit feedback for teaching presentations, let’s start with the good stuff.

PROS

* The puzzles! I thought the puzzles I encountered tended to be of very high quality, in terms of their creativity, their cleanness, and their fairness. I confess to being one of many people who wondered if an NPL-heavy construction team would write a more “old school” Hunt dominated by crosswords and PDFable puzzles, in contrast to the robust multimedia/interactive content that has made recent Mystery Hunts and many recent online hunts vivid and exciting compared to the Mystery Hunts I started on. (The definition of a Hunt “puzzle” has changed intensely over the last two decades; most of the puzzles I wrote for 2000 would barely qualify as one step of a modern puzzle.) I had zero reason to worry, as puzzles came in a variety of formats and called on a variety of skills, and they felt like they came from a team that has been paying attention to the greater puzzlehunt landscape, not just Mystery Hunt. When I was able to sit down and solve things, I frequently had a blast doing so.

* I am a sucker for themed rounds (and have been ever since 2004 when ATTORNEY first wrote a Hunt where the presentation of the rounds really made them feel distinct from each other) and I adored the selection of round themes, the incorporation of those themes into puzzles, and the exquisite art design that made it easy to remember which round every puzzle lived in. I didn’t get quite as much of a rush from the Investigation or Ministry, but once the chunky part of the Hunt opened up and I got to see both Lake Eerie and Noirleans, I had that rush of wanting to solve enough to see what big reveal was coming next, and that’s what I want out of a puzzlehunt that lasts more than a day.

* Speaking of Pen Station, I really liked that the structure and scope of the rest of the Hunt was fairly clear when we got there. The MTA-styled line board made it clear how many rounds we should expect and helped to unite these disparate zones into a shared universe. When Plot Device opened, it was clear that this “round” was different, but not immediately clear how, and that was a nice balance of clarity and mystery.

* Also in the realm of balance, I thought the balance of event rewards was on the nose. It’s been tradition in many Hunts (including ones I’ve worked on) for the events to be a requirement for Hunt completion, but my calculus students can tell you that required things are not automatically fun, and especially in an online event, attendance may not be easy. I liked that this years events were not mandatory, but that they gave just enough free answer credit to feel rewarding without breaking the rest of the system.

* If you’re reading this, there’s a really good chance you’ve already watched the reward video for Recipeoria. If you haven’t, then either (a) solve Shopping List, the Recipeoria meta, since it’s a fun puzzle and the reward video partially spoils in, or (b) just watch the video. I didn’t watch it during Hunt (more on that later), but afterward, Erin Rhode told me to watch it immediately, and my jaw DROPPED. Hell of a get, Palindrome.

CONS

* I’m going to devote the most detailed criticism to the appropriately themed elephant in the room (and most frequently cited issue during our Slack post-mortem): The Ministry metapuzzle, and more specifically the fact that the majority of the Hunt was gated behind solving it. This left Setec in the fairly unpleasant position of unlocking no new puzzles, regardless of other progress, for hours on Friday night. I think we had just informed Palindrome that we weren’t having much fun (an hour or so into literally only having one puzzle open, because we’d solved everything else), when we figured out what we were missing sans hints and were finally able to open some exciting new stuff.

Now, let me be clear that I’m not objecting to the metapuzzle itself… I think it was a great puzzle! I personally think it was underclued, but only in that nothing in the puzzle clearly tells you you should be going back to reprocess the original 25 answers; since those had been used up, we spent most of our wheel-spinning time staring at the flavor text, mural, and five meta answers, which is not enough to do anything. I think a 25×5 grid would have done wonders to let us know what inputs we should be considering, particular in a meta intended to be solved by as many teams as possible. My objection is to the gating. Any puzzle in the Hunt might stump teams and create a bottleneck. If that bottleneck occurs at the end of the Hunt, it’s still not ideal, but at least teams have had the opportunity to see everything they might be interested in. A gigantic chunk of the puzzles, story, and art live in Pen Station, and a lot of teams never gained access to that area at all. I think this is a problem, and it’s one that’s arisen and has been solved before.

Who’s ready for Story Time with Dan Katz, Bay Bay? (That was a wrestling reference.) Back in 2009, when dinosaurs roamed the earth, The Evil Midnight Bombers What Bomb At Midnight similarly gated Outer Zyzzlvaria (more than half the Hunt, divided into rounds with weird-ass structures) behind the board game reconstruction puzzle that served as the capstone to Inner Zyzzlvaria. We did this for all the reasons Palindrome probably did… we wanted to focus teams on the task at hand until they completed it, the story called for teams not to discover Outer Zyzzlvaria until they had a reason to, et cetera. Except when running the Hunt, we realized Friday night that lots of teams were getting stuck there, and that, in particular, unless we gave casual teams enough hand-holding to get through a very daunting puzzle, they weren’t ever going to make it to Outer Zyzzlvaria. So we improvised. We tweaked the plot a little bit, our tech master pulled some levers, and boom. Solve enough puzzles, you can get to Outer Zyzzlvaria. The recent Setec hunts took this approach into account: each had a big midgame set piece with a capstone interaction and story reveal, but if you didn’t complete it for some reason, you could still see other stuff.

Playing devil’s advocate against myself, I know a common criticism of the 2019 Hunt was that for many casual teams, the puzzles constituted a molasses flood of their own; we explicitly decided that we would eventually release every puzzle to every team no matter what, and since our number of puzzles was arguably too high, some teams were unquestionably overwhelmed. So is it better to hide the hard stuff from teams until they earn it? Or to give them potential access to everything, but encourage them to explore the shallow end first? Personally, I’d rather give teams the choice. According to the wrap-up, 60 teams solved Fruit Around, which is a great stat for a midgame accomplishment, but with the gating, that means (N-60) didn’t even know there was a Pen Station until after the Hunt. And I imagine a disproportionate number of those fenced-in teams were casual student teams, which doesn’t sit well with me.

* On a closely related note, except for Where The Wild Things Are, the puzzles involving physical objects were buried waaaaay too deep. Since the wrap-up stats graph only showed the top nine teams (more team stats and submission logs, please, Palindrome) I have no idea how we placed compared to the pack; I’m sure we weren’t top ten, but I bet we were top twenty? And we didn’t unlock the second puzzle requiring a box until just before 6pm (using up our manuscrip because we didn’t think we could after 6). If we were anywhere near the front of the pack, that means the vast majority of teams paid shipping for objects they never got to use (including all the teams who never left the Ministry).

* Compared to recent Hunts, I thought there was a surprising lack of clarity about when Hunt would “end.” Unless I missed it, there was no advance “HQ will run until Time X, or when the coin is found, whichever is later” announcement, so given that last year’s virtual Hunt ran through Monday, I mentally prepared myself for this one to do the same. Then when the “coin is found” announcement came with a message that HQ would close at 6, it was a harsh blow; we were at least seven metapuzzles away, and it was clear that we were going to land farther from finishing than in any recent year. I pushed hard until 6 (and I believe we solved two more metas but got stuck with 10/13 on Heartford) and planned to solve casually into the night, but the fatigue I talked about earlier knocked me out and I had to jump ship. Then at wrap-up, I was really surprised to hear that some teams finished after 6. Wait, you could still finish after HQ closed? That’s a great feature, but it was not at all clear to us. A lot of our team dropped out at 6 if not before, and if we knew that Hunt was still “officially” going, I think we might have approached things very differently.

I do think what ended up happening, a combination of human interactions ending Sunday evening (provided the coin is found by then) but advancement still active until Monday morning, is a really nice compromise that could become an excellent tradition if it remains feasible once Hunt is on campus again; when Death and Mayhem kept Hunt rolling until Monday, I remember thinking that was very generous but should not become an expectation. Ultimately, the constructors should be able to decide when they want to close up and sleep. But they should be transparent about what can be done when, and as far in advance as possible.

* I thought last year’s Hunt was too long. I thought this year’s Hunt was too long. See last year’s posts for relevant arguments. But hey, nine teams finished and the winners found the coin at a fairly reasonable time, so maybe this is becoming an “if the music’s too loud, you’re too old” scenario. I do still think that as long as Hunt stays long, teams will feel like they need to be giant to compete (though UNICODE EQUIVALENCE coming in 4th with only 30 people might make them the new Evil Midnight), and if teams are giant, construction teams will think they need to write a huge Hunt to appease them, and this process can be extrapolated to pinpoint the heat death of the universe.

* Finally, this was a point of contention when I brought it up with Setec, but I thought that structurally the videos may have been too skippable. I consider myself a person that cares about the plot of Hunt, and I didn’t feel tuned into it (I didn’t realize Tock was a significant character until he started popping up in some flavortext). I didn’t skip videos because they were bad… the ones I watched were lovely… but there were a lot of them, and they didn’t feel like they needed to be watched, so I solved puzzles instead. I think both this Hunt and the Galactic Hunt could potentially have benefitted from a less is more approach to both story and interactions/videos. Since Hunt is above all a puzzle competition, I think it’s really helpful for a puzzlehunt to have a small number of story beats that are aggressively highlighted so people are tuned into them. If you want to have a reward of some sort for every metapuzzle, I think that’s fine, and many people will enjoy them, but I would really like to be pointed at the story elements that matter most. But I may be in a unique middle ground on this; most people I talk to either don’t care much about interactions at all or want as many of them as possible, so perhaps it’s weird that I just want a few that I can’t easily avoid.

As part of my job, I write a lot of feedback on people’s teaching, and what’s happened above often happens in those feedback e-mails; the criticism takes up way more space, just because there’s more to say about something that’s flawed and could be fixed then something that is already great. (This is why disassembled model kits have longer instruction manuals than, say, bottles of water, even though my son would need help with either of them.) So as I do in those e-mails, let me emphasize that just because there are more words devoted to the cons than the pros above does not mean that overall this was a bad event. I thought it was a really good Hunt that I didn’t get to participate in as much as I wanted for reasons, and that some casual teams maybe didn’t get to participate in as much as they wanted for other reasons. Sincere thanks to Palindrome for their talent and hard work, and I’m excited that next year’s Hunt will be written by teammate, the authors of the Puzzlvaria Puzzlehunt of the Year from 2021. Surely this is not a coincidence, so if you want to win next year’s Mystery Hunt, get to work on writing my favorite online puzzlehunt of 2022. Guess what the current leader is?

I could print all of this text again backwards to make this post a palindrome, but let’s just pretend I did and move on with our lives.

My Favorite Puzzlehunts of 2021

Disclaimer for all three of my year-end top ten lists: Descriptions of puzzles/hunts may include spoilers, especially as you approach the top of the list and I have more detailed gushing to do. Also, keep in mind that these are my personal favorites, which means they are shaped by (a) my personal content tastes, (b) the fact that I tend to like harder puzzles (which doesn’t mean easier puzzles are bad!!), and (c) the fact that I happened to solve or co-solve these particular puzzles, since hunts have swelled to the size that I can rarely pay attention to every puzzle my team solves.

A good blogger would add links to all the relevant puzzles and hunts, but I’ve already spent too much time writing these posts. Maybe I’ll add them later, and if not, I bet you can all use Google.

  1. UMD Puzzlehunt

This is specifically the UMD Puzzlehunt from January; I believe they’ve had another since then that was on-site without the puzzles being archived online. I really hope they post the second event, because the first event was quite good, with a nice variety of polished meaty puzzles, a fun plot twist, and an excellent final metapuzzle.

  1. Huntinality

Wah! It was exciting to see a fresh hunt by new contructors (early in the year before there started being multiple nontrivial events per month) with a fun theme. I might be a little biased here in that I too believe Waluigi has been unjustly snubbed by the Smash Brothers design team. As have Raz, Mike Jones, and Guybrush Threepwood.

  1. Puzzle Boat 8

Recent Puzzle Boats have been different for me than the older ones due to COVID; Puzzle Boat was traditionally the yearly event where I convinced some Boston-area friends to schlep out to my house in the suburbs and solve in person, and we haven’t been able to do that in 2020 or 2021. In addition, the size of Puzzle Boat is becoming a bit less novel as online hunts become larger-scale, and the mostly-PDF format limits some of the interesting things that are being done with interactive puzzles. On the other hand, the overall structure of grouping puzzles into metas (which has been used in lots of other places since but was mostly innovated by PB) is still a really fun and daunting task, and it continues to be insane that Foggy Brume can create an event this large on his own, especially in a year when he’s also contributing to Mystery Hunt.

  1. Puzzle Rojak

I honestly wasn’t expecting much from this event since I know almost nothing about the authors, but a mutual friend assured me that the constructors knew what they were doing. And that was very true! While a number of the puzzles we didn’t solve fell into my weakest puzzlehunt categories (I’m unlikely to touch a puzzle with a double-digit number of chessboards or one with languages in a non-Western alphabet with a ten foot pole), Go-Karts, Drop Tower, Sea Caves, and Shallow Waters were all delightful (one made my top ten list, and I was tempted to include others but wanted to control for recency bias), and I also really enjoyed how the final metapuzzles came together.

  1. Puzzle Potluck

There have been a lot of great sets of interlocking puzzles this year, so as we approach the top of the list, you’ll find that in many cases, what makes the difference for me is a compelling theme with surprising story moments. I have minimal experience with Animal Crossing beyond memes, Smash Brothers appearances, and that heartbreaking story from years ago about the kid’s mother, but I definitely know Among Us, and I cannot say I was expecting to come across a brutally murdered Animal Crossing character. Mashing up the two social video games that gained the most traction during the pandemic almost feels like a no-brainer in retrospect, but I certainly didn’t see it coming, and I enjoyed the result. That plus a nice pairing gimmick made for a solid Potluck outing in 2021.

  1. Silph Puzzle Hunt

While I don’t like to think of myself as a person who values style over substance, I have at times tried to delve through the Smogon Puzzle Hunt archives, and I generally haven’t made it very far because the puzzles are PDFs plunked into a folder system. I don’t know if people are getting tired of all of the online hunts that use forks of the gph-site hunt code, but I think it makes those hunts look polished and appealing, and it’s arguably spoiled me for anything more gritty. This year’s Silph Hunt was an attempt by the Smogon authors to port the event from a Pokemon message board to a mainstream audience, and I found the result very entertaining. Difficulties seemed nicely tuned for the first and second phases, metapuzzles were nice and thematic, RED SUS was aggravating in all the right ways, and I haven’t stopped hearing nice things about The Minimeta That Goes Wrong (though I only assisted in the final extraction, which was clever but bottlenecky). It is a testament to the quality of this hunt that I have almost zero (maybe less than zero) interest in Pokemon, and I still thought this was a great event.

  1. QoDE

Shortly before QoDE, the constructors released a short teaser puzzle that revealed its Batman theme. Speaking as the author of the Learned League One-Day Special on Batman villains, I immediately decided the best way to carry out this theme would be one puzzle per ridiculous BatUniverse villain, and I was not disappointed.

One of the big changes to the online huntscape during the pandemic, besides just the obvious increase in content, has been the increase in content difficulty. For many years, there was a significant gap between the average puzzle difficulty in, say, the Mystery Hunt versus most online events, until Galactic Puzzle Hunt (particularly starting in its second year) really upped the ante for how Mystery Hunty an online event could be. This year I didn’t expect to get those sorts of puzzles in the window between Galactic and teammate, and QoDE dropped in unexpectedly with some awesomely challenging content. I had some issues with the presentation of the final metapuzzle, but all the other metas were great (including my favorite of the year, and a beautifully illustrated first-round capstone) and the metaswere preceded by consistently interesting puzzles with fun flavor from a universe I personally enjoyed. Na na na na na na na na good hunt.

  • 3. MIT Mystery Hunt
  • 2. Galactic Puzzle Hunt

(Please excuse the weird double bullet points above… WordPress was NOT psyched about two consecutive numbered items in reverse order for some reason.)

Look some planes Galactic Trendsetters what a coincidence some more planes should be extremely proud of themselves for delivering two high-quality large-scale events in a single year (I know when I saw they were doing a GPH this year, first my head exploded, and then I got really excited that it was during the summer when Jackie and I have more flexible schedules). However, I’m probably surprising some readers, and maybe some members of Galactic, by putting GPH above Mystery Hunt. This doesn’t mean GPH was an objectively better event; the Mystery Hunt was a phenomenal accomplishment this year, especially under unprecedented difficult circumstances.

But as I said in my Hunt recap, the remote nature made me feel more disconnected than usual from my team, and I didn’t get familiar enough with the avatar space quickly enough to feel like I could process that element of the Hunt. GPH, on the other hand, had more digestible length, and my team was small enough that I felt I could interact with them fully and take in most of the hunt. Does this mean Mystery Hunt has passed me by? I hope not, and I suspect I would have enjoyed the Mystery Hunt even more had I been in a room with the rest of the Setec crew. But at least in the form I experienced the two events, I got a more satisfying experience out of GPH. Yet I got an even MORE satisfying experience out of…

  1. Matt & Emma’s Carnival Conundrum

Not to drive a wedge between sibling teams Galactic and teammate, but in 2021, I think teammatehunt was the highlight of my puzzlehunting year. The puzzles were high-quality and challenging (just as they were in the 2020 version) and while the pairs of puzzles that interacted with each other were sometimes frustrating, the connections that revealed themselves were often pleasing.

But I think the thing that propelled this event to #1 on my list was one of the most impressive story beats I’ve seen in any puzzlehunt I can remember. After last year’s Matt & Emma hunt, I commented that I was surprised at how wholesome the theme was and continued to be; I’m so used to puzzlehunt themes being darkly comic that I was certain the birthday party would turn into Five Nights At Freddy’s, rather than just a jaunt through a delightful fantasy realm. One of the effects of that wholesomeness is that I think of Matt & Emma as two sweet kids, and even though I don’t know much about them, I know they care about each other. So when the magician in this year’s hunt told each of them bluntly that not only was their sibling gone, but that they never existed… and suddenly the previously bright side design turned dark… I remember gasping audibly.

That said, the rest of the story, as told through silent images, didn’t work for me nearly as well. I got the general beats but didn’t feel story happening with every puzzle, and I didn’t need to. But that one big shift was so simply and artfully executed, that it gave me a real emotional investment in helping the main characters. That took what was already a great set of tough, well-written puzzles and elevated it to something more meaningful, at least for me. That was enough to bring it to the top of the medal stand.

Thank you to everybody who solved puzzlehunts and especially wrote puzzlehunts this year. 2021 was a roller coaster of a year, as COVID still ravaged the earth, which is awful in almost all ways, but it did facilitate more puzzlehunting opportunities. Meanwhile, I had a child, which is great in lots of ways, but it did facilitate less puzzlehunting time for me personally. I’m grateful to my wife for doing more than her fair share of Simon-wrangling on certain weekends to allow me to squeeze in as much solving as I could, and I’m grateful to this community for continuing to do cool things and support each other’s projects. Sorry for the sparse posting this year, but I hope to keep encountering many of you online and (fingers crossed) in person in the new year.

My Favorite Metapuzzles of 2021

Disclaimer for all three of my year-end top ten lists: Descriptions of puzzles/hunts may include spoilers, especially as you approach the top of the list and I have more detailed gushing to do. Also, keep in mind that these are my personal favorites, which means they are shaped by (a) my personal content tastes, (b) the fact that I tend to like harder puzzles (which doesn’t mean easier puzzles are bad!!), and (c) the fact that I happened to solve or co-solve these particular puzzles, since hunts have swelled to the size that I can rarely pay attention to every puzzle my team solves.

A good blogger would add links to all the relevant puzzles and hunts, but I’ve already spent too much time writing these posts. Maybe I’ll add them later, and if not, I bet you can all use Google.

  1. Candela’s Mystic Correspondence (Silph Hunt, Level 51 and lydian)

The mechanic here is slick and well-executed, even if it doesn’t really break much new ground. What I really liked from a thematic perspective was using the text of “Fire and Ice” as the data set for the collision between the Pokemon fire and ice factions. This is a good time to point out that even though this was one of my top ten metas of the year, it’s still not even my top “fire and ice” meta of the year.

  1. Infinite Corridor (Mystery Hunt, Jon Schneider)

I have to be honest: Even though this is ostensibly a list of my favorite metas, Infinite Corridor makes the list more for slack-jawed awe than for my remembering it as an enjoyable solving experience. (To quote one of my favorite test-solve comments I ever got one of my puzzles: “Do I like it? I don’t know, but I respect it.” Complicated metas are often not my jam, but I liked that this meta facilitated five puzzle families that each had both interesting mechanics and submetas to solve in their own right. Plus, we had a teammate who coded the Python script (the Infinite Corridor Simulator Simulator?) to pull the answer once we had enough submeta answers, and that teammate happened to not be around when we had enough data to finish, which meant I got to run the code and be super-excited when it actually spit out a thematic answer instead of just another word.

  1. Wah Street Bets (Huntinality, Benji Nguyen, Dan Simon, and Ryan Liu)

While the finale to Huntinality was a little reminiscent of the cookie clicker in the second Galactic Puzzle Hunt, I liked this more because (a) there was a greater variety of stuff to do, and (b) I didn’t have to tensely watch my teammates click buttons just the right number of times so that we didn’t screw up and have to start over. Then the very last step did a great job drawing our attention to something we didn’t notice when solving the subpuzzles for a nice punchline. This felt more like a gentle victory lap than a difficult capstone to the event, but it served its purpose nicely.

  1. Magical/Entanglement (Matt & Emma’s Carnival Conundrum, Herman Chau, Rachel Wei, and Patrick Xia)

The one puzzle my team never solved in the first round was Radio Noise, which contributes the most to the answers to this pair of metas… fortunately, the output is the most thematic, so it’s easiest to guess (though not as easy to use it to backsolve the puzzle) so we were able to intuit the right beginnings, and that arguably made the solve even more satisfying. This was also a nice teaser for the main gimmick of the rest of the hunt, without giving it away outright.

  1. Final Metapuzzle (Edric’s Truzzle Hunt; Edric Haleen)

This was the first of Edric’s events that I fully participated in, so I didn’t know what to expect. It was reminiscent of the old Australian hunts in a lot of ways (including the visual presentation). But those hunts frequently had underconstrained answers and inelegant and/or inscrutable metapuzzles. The Truzzle Hunt meta, on the other hand, required the answers to be ridiculously constrained in a way I did not notice at all until I had to, and with those constraints in place, very little shell was needed to produce an answer. It was very pleasing to discover that so much structure had been hidden the whole time in plain sight.

  1. Student Center (Mystery Hunt; Jon Schneider, Rahul Sridhar, Anderson Wang)

The Student Center meta is another metapuzzle I already talked about in my Mystery Hunt writeup. It’s high on the list due to its use of one big aha, a bunch of fun little mini-ahas, and a lot of logic-poking to work out what goes where once you know what’s happening. It’s also very self-confirming for a large metapuzzle; once you think you know how to interpret a club, the data does a good job letting you know if you’re right or not. You could also argue that the Student Center meta incidentally includes its submetas, which means it includes both Random Hall and MacGregor Hall, which were both awesome. In extremely different ways.

  1. Telescope (Galactic Puzzle Hunt; Jon Schneider with contributions from Brian Chen, Colin Lu, Rahul Sridhar, and Anderson Wang)

It’s been a while, so I might be misremembering, but early on when we had 36 dots and the pictures of eyes, I quickly wanted this to tie into the eye chart meta from the beginning of the hunt (which had seemed awkwardly underconstrained at the time). The payoff here is really nice; I love the epicness of revealing that the pyramid-shaped thing you were looking at in Round 1 is actually a nice orderly square if you just view it from the right angle. My team almost certainly didn’t build the square as efficiently as we could have, but it was satisfying to do so, and even though my teammates worked out the right interpretation shortly after I fell asleep, I was still pleased to see how it worked in the end.

  1. Bulletin Board (Puzzle Potluck; Curtis Liu, Darren Yin, and Rajeev Nayak)

You’re just cruising along, thinking, “Okay, I guess these visually hinted transformations are kind of cute, and I can apply them to each of the answers, but I’m not sure what to do now…” And then you realize that these psychopaths (no offense) managed to find answers that could each take on two transformations each. I’m giving this a very high ranking for the wow factor of that mechanic, the appropriateness of this meta for a hunt in which you had to pair up puzzles and chain together locations, and a solid thematic punchline to tie it all up.

  1. Hall of Mirrors (Matt & Emma’s Carnival Conundrum; Jacqui Fashimpaur, Liam Thomas, and Samuel Yeom)

Metapuzzles often fall into one of two categories: the type where there’s one big aha, and once you figure out the gimmick, you can apply it and instantly grab an answer (nothing wrong with that); and the type where the answers are inputs to a multi-step puzzle that requires a lot of effort, to the point where the metapuzzle is itself just another puzzle, but one you have to solve (maybe something wrong with that, but that’s in the eye of the beholder). Hall of Mirrors landed in a nice space between these, where there were multiple ahas and some gruntwork to do, but the puzzle presentation guided us through it fairly and the properties of the answers were important enough to make this not feel like a standalone puzzle. When I really wanted a mirror to change the vowels of words, and a teammate pointed out how that was embedded in the design, I was floored. Solving this puzzle was a series of “Wouldn’t it be cool if it worked like this?” moments, where it almost always worked just like that.

  1. Firefly & Mr Freeze (QoDE; Scott Handelman and Jonah Ostroff, featuring Adam Maresca)

I did promise you another temperature extremes meta, and this one’s all the way at the top of the list. This had an elegant presentation, it was fun to solve, and it relies on a really clever data set (big spoilers coming here): groups that not only have two clear members associated with hot and cold, but that also have a member with one H and no C’s, and another with vice versa. When solving this meta, we spotted the first of these properties first, and I was delighted when the second popped out of the answers we had to work with. If you’re an elegance nitpicker, you could argue that the plus/minus numbers in the shell make the construction slightly easier, but there’s so much neat stuff going on in an organized fashion here that I have no objections to shifting the positions to make the whole thing work.

This meta also gets bonus points because it admitted an answer that fit a Batman puzzle (in a Batman Hunt) so thematically that I was 100% sure the meta was written around forcing that phrase into the answer pool. I was subsequently informed that this was not the case, and it has caused me to reevaluate my own views on creationism ever since.

My Favorite Feeder (Nonmeta) Puzzles of 2021

Disclaimer for all three of my year-end top ten lists: Descriptions of puzzles/hunts may include spoilers, especially as you approach the top of the list and I have more detailed gushing to do. Also, keep in mind that these are my personal favorites, which means they are shaped by (a) my personal content tastes, (b) the fact that I tend to like harder puzzles (which doesn’t mean easier puzzles are bad!!), and (c) the fact that I happened to solve or co-solve these particular puzzles, since hunts have swelled to the size that I can rarely pay attention to every puzzle my team solves.

A good blogger would add links to all the relevant puzzles and hunts, but I’ve already spent too much time writing these posts. Maybe I’ll add them later, and if not, I bet you can all use Google.

  1. Intersections (Galactic Puzzle Hunt; Brian Chen)

While I’ve sung for a whole bunch of hunt puzzles I’ve written, it’s pretty rare that I solve one by singing. But that turned out to be the best strategy for Intersections; once I knew what I was trying to do, I found myself singing duets with the puzzle author to find the unison notes. This could have been an unpleasant experience, except the alt-melodies were both written and performed excellently, so I thought we sounded quite pretty together. (I just checked with my wife, who was sitting next to me at the time, to see if it actually sounded good. She does not remember.)

  1. Cafe Five (MIT Mystery Hunt; Nathan Pinsker and Josh Alman)

I won’t say too much here about Mystery Hunt puzzles since I already posted about my favorites in January, but if you want the opportunity to show off by speed-solving all sorts of different puzzles, Cafe Five is for you! (Barbie’s Murder Party at the House on the Hill is also for you, but that was from last year.) It’s also the sort of puzzle that requires so much of the team to pay attention to it that it’s instantly part of the shared Mystery Hunt consciousness. I expect “L. Rafael Reif approaches the cafe” to be slang for “this puzzle suddenly got much harder” for years to come.

  1. The Meta Meta Meta… Puzzle (Galactic Puzzle Hunt; Yannick Yao)

The Author’s Notes for this puzzle mention the Infinite Corridor meta from the MIT Mystery Hunt, and this felt very much like a more approachable version of that epic puzzle recursion. There are a lot of levels of discoveries to make, and it was fun to chip away at it with my teammates, particularly while it was still in “blurry” mode.

  1. Go-Karts (Puzzle Rojak; aki and Jonathan)

I admittedly didn’t carry out some of the more tedious word-searchy steps of this puzzle (props to my teammates Scott and Jenn for doing most of the grunt work), so I might be biased via only seeing the flashy parts. But there was something very satisfying about seeing all the messages fall out of the puzzle, and then to hear characters pop up in the sound clips at just the right time (once we knew to expect them), and on top of all that an unexpectedly jaw-dropping extraction step. It also helps that I like Mario Kart. I’m-a-gonna win!

  1. Fun With Sudoku (MIT Mystery Hunt; Josh Alman and Mitchell Lee)

This is another one I posted about after Mystery Hunt. Logic puzzles plus combinatorics equals A-OK in my book, and this resulted in a particularly satisfying team solve.

  1. All That’s Left To Do is Extract (Matt & Emma’s Carnival Conundrum; Ivan Wang, Alex Irpan, and Rachel Wei)

It’s always fun when a puzzle takes you to things that were hidden in plain sight in some corner of the hunt website (well, I should say it’s fun as long as you’re guided there in a fair way). ATLTDIE takes you on a pretty exhaustive tour of the teammate website and does some fairly bonkers things along the way, from hiding data in what you thought was your own image file, to embedding Braille in the otherwise innocent looking favicon (a term I learned from this puzzle), to making the website respond to the Konami code.

  1. Make Your Own Math Quiz (Galactic Puzzle Hunt; Jakob Weisblat and Josh Alman)

It wouldn’t be a GPH without a Make Your Own Something Or Other, and having made quite a few math quizzes in my time, this felt like home. The concept of students complaining that questions aren’t similar enough is actually common in some situations, and so the interpretation here is pretty funny. And from a puzzling perspective, figuring out how to make the constraints all work at the same time was satisfying, with a great extraction punchline right at the end.

  1. Qatalog (QoDE; Jonah Ostroff)

Chatting (and solving!) with puzzlehunters on many teams this year has brought at least one thing sharply into focus… I use OneLook more than a lot of people, and I use Nutrimatic less than a lot of people. I had also encountered Qat, but I hadn’t made much use of it because the syntax is fairly intmidating. Qatalog simultaneously served as a really effective Qat tutorial, and an ingenious array of puzzly ways to utilize said unusual syntax, with the most thematically appropriate final step that you could ask for. (It’s nice when your puzzle about Website X ends with Website X spitting out your answer verbatim.) “Minimeta” puzzles are in vogue right now and are almost always appreciated (The Minimeta That Goes Wrong was likely a favorite of many people, but I just wasn’t around for most of the solve), but I loved this one in particular for both its creative variations on a theme and for its ability to actually teach me something that I’ve used since.

  1. Meta-Eval Times/Pin the Tail (Matt & Emma’s Carnival Conundrum; Andrew He, Katie Dunn, Catherine Wu, and Patrick Xia)

I’m considering this entangled pair of puzzles from this year’s teammatehunt as a single entry. Puzzles with lots of parallelizable mini-ahas are always fun, and the first stage of Meta-Eval Times delivered in that respect; meanwhile, after I spent several years of my life mapping Pin The Tail, I was thrilled that one of my teammates recognized it as an Among Us board. But by far the highlight of the puzzle, after spending way too much time trying to satisfy all the advanced Meta-Eval constraints at once, was remembering how actions in Remember to Hydrate had affected Mystery Manor and having the realization, “When we kill crewmates in Pin The Tail, does anyone die in Meta-Eval?” Not only is this a wonderfully unexpected effect, there’s also something delightful about the idea of writing a metapuzzle for picky test-solvers and assassinating half of them to get your puzzle into post-production. No offense to anyone that I’ve written Hunt with. You’re all wonderful, and it’s been long enough that I do not want to murder any of you.

  1. Divide and Conquer (Galactic Puzzle Hunt; Lewis Chen and Anderson Wang)

It was difficult to rank most of the items in my three “best of” lists, except for this puzzle, which frankly never budged from the #1 slot for non-meta-puzzles since I finished solving it. Back in the early days of Setec Mystery Hunt writing, there was a house rule that a puzzle shouldn’t have more than one aha. Puzzles were much much much simpler then, and good puzzles these days often have multiple steps; the true art to this is giving the solver enough help to progress but enough resistance to feel challenged. And boy, was this challenging… I think I devoted a full afternoon to it, with Jackie’s help.

Having quarter-specific approval/rejection for the example puzzles was the perfect amount of assistance to help me identify regional mechanics. And I suspect I would have found the puzzle overwhelming if we’d had to solve every bit of it, but getting two of the mini-puzzles and recognizing the four-letter pictures was enough to crack the letter-to-variant relationship and solve just enough of the other feeders to complete the correspondence grid. Then we were able to crack enough of the big grid to get the clue phrase without the whole picture; thankfully after calling in the one example I knew of that could answer the clue phrase, someone on my team knew another correct one. I’m the opposite of a Star Wars fan, but I’ll still mine it for a metaphor; this puzzle is like an imposing Death Star that seems impossible to overcome from a distance, but there are enough (intentional!) cracks in the armor, that with enough skill I was able to fly in, drop a bomb, and break the thing wide open. I haven’t had a more satisfying solve this year, and probably not in the last few years either.

Year-End Posts Coming Soon!

Hello all! I hope that you’re safe and well as you’re reading this. COVID continues to ruin the Greek alphabet for all of us.

I’ve participated in a lot of amazing online puzzlehunts this year with a nice variety of teammates (in addition to my usual hunting with Killer Chicken Bones for Galactic and Mystik Spiral for pretty much everything else, I want to thank members of TruFact, Have You Tried, and Herrings for helping me keep things fresh throughout the year), and I have done a terrible job documenting them. But over the last few months, the High Fidelity part of my brain has been obsessively ranking puzzles from the past year, and at some point I started actually writing them down.

So! Coming after Christmas! My highly subjective top ten lists of my favorite metapuzzles, feeder puzzles, and puzzlehunts from a year of solving online. Will your favorite make the list? Maybe! Will something you wrote make the list? Perhaps! Will you agree with the entire list? Certainly not, but that’s what the comments are for! (That and bot spam. But WordPress is pretty good at killing most of that.)

See you at the end of the year, and have a happy holiday.

The Summer of Puzz

Hi folks. I notice my last post’s subject included “final thoughts” in the title, so some of you may have assumed I disappeared off of the face of the earth. I did not, but I did two things that are isomorphic to falling off the face of the earth:

  1. I taught two calculus courses online, which is something I also did in the fall, but it was a lot harder than in the fall; I attribute that to more student dishonesty (sigh), more student unrest, and the rather distracting fact that…
  2. My wife and I had a baby! Simon Anderson Katz was born on March 10, pretty much right on time, happy and healthy. He’s our first child, which is something I say to clarify that we haven’t done this before, not to imply there will be a second child. (He’s great, but we’re good with one of him.)

As it turns out, there were a number of good puzzlehunts during my blogging absence, and there are a few on the horizon too. Hopefully you’re getting your puzzlehunt scheduling info from Puzzle Hunt Calendar, which updates more often than I do, but here are some of the things coming up, and then some things you should check out if you missed them:

Upcoming

Most imminently, Huntinality starts tomorrow. This is the latest in a trend of high-level puzzlehunt teams contributing to the hunt community with online hunts, this one coming from Cardinality (who I didn’t previously realize was Stanford-based, explaining the name). They’re using a re-skin of the GPH web code, which is very purple because Waluigi is very annoyed according to the prologue. I’m looking forward to solving with Culms of Munj, with some friends from my former Mystery Hunt team.

Most improbably, there’s a Galactic Puzzle Hunt in July. This is absolutely ridiculous given that Galactic just wrote the most recent Mystery Hunt, and can’t possibly have had the time to create a separate puzzlehunt, especially not one of their usual size; but it’s advertised as having about 40 puzzles, which seems standard for GPH. I’m really looking forward to solving this (with Killer Chicken Bones), as GPH has become one of my favorite non-Mystery-Hunt events on the calendar, and I definitely felt its absence last year.

Most secretly (because it’s not on the PH Calendar), Puzzle Potluck 4 is tentatively scheduled for August, according to the website for Puzzle Potluck 3. PP3 had a really cool structure and serious wow moment (that was maybe a little bit dulled by the same “secret theme” occurring in another event earlier that year) but I’m looking forward to seeing what they create next. Especially because the current trend in online hunts is for the FAQ to frequently say whether the event will be easier or harder than Puzzle Potluck to try to gauge difficulty. Will Puzzle Potluck be easier or harder than Puzzle Potluck?

Downgoing (no longer upcoming)

The twice-a-year Puzzlehunt CMU keeps getting better, and yet I keep forgetting to take it seriously and get a team together. I really liked the multiple interpretations of “pirate” that formed the theme and structure, which reminded me of the triangle BAPHL but felt a bit tighter (and I don’t know how I didn’t see a baseball pirate coming in a puzzlehunt out of Pittsburgh).

If you’re interested in something that’s more of a snack than a full meal, consider the most recent P&A (where my wife and I managed to short-circuit the meta in under an hour), or the Inaudible Hunt, which was written as puzzle-writing practice by a subset of my aforementioned former Hunt team (who were most recently We Can’t Hear You, You’re On Mute in the 2021 Mystery Hunt). They also advertise on that site that they’re actively looking for other new authors to collaborate with, so if you’ve never written a puzzlehunt puzzle and want to learn how, there’s contact info at the link above.

Finally, with the general increase in online puzzlehunt density and my limited free time, I admit to some puzzle snobbery in often deciding whether to set aside time for an event by asking, “Do I know who these people are?” Sometimes that causes me to make bad decisions, like not realizing until a couple days from the end of Paradox Puzzlehunt that it was pretty great (through word of mouth on social media). Sometimes hunts from new constructors have filler or very easy puzzles, but everything here was clever, meaty, and well-constructed, and I enjoyed their take on the theme. It was a shame that a change in a third-party site sort of broke their Hunt structure, but they found a good way to set up a way for teams to still finish (which I did just under the wire). I hope there will be a Paradox 2, and I’ll know to pay attention to this one!

I’m going to shift my attention to the tiny person hiccuping across the room. See you when I see you, get vaccinated if you haven’t already, and may your less-than-half-the-letters wheel-of-fortune guesses be productive!

2021 MIT Mystery Hunt, Part 3: Some Puzzles and Some Final Thoughts

(This is a recap/review of the 2021 MIT Mystery Hunt, which happened this month. Puzzles and solutions can currently be found here. This recap may contain spoilers.)

Some puzzles are not metapuzzles. In the puzzling community, we eloquently call these puzzlesthatarenotmetapuzzles. In alphabetical order, here are some of those I wanted to comment on:

Analog Circuitry

I joined this puzzle late, when it was one of three puzzles bottlenecking our progress in the Basketball round. Teammates had already figured out which color combos created the correct subwords, and they’d worked out about half of the gate actions, but I noticed that most of the identified actions weren’t clearly related to the type of gate (AND, OR, XOR, etc.). I found that a bunch of them were bitwise actions on the letters, and also hypothesized that the wire colors told us whether the outputs were valid words. That was enough for us to work out two of the three final outputs and infer the answer.

The main reason I wanted to bring this puzzle up is to highlight just how much the definition of a Hunt puzzle has changed. Back in 2007, I wrote Transmogrifiers, a puzzle in a somewhat similar spirit that asked solvers to analyze the results of applying sequences of functions to letter strings. Fourteen years later, this puzzle has better presentation, asks solvers to do way more, and is much more satisfying. Sometimes I think the entire 2000 Hunt would count as one puzzle in 2021.

Cafe Five

I definitely wandered into a Cafe Five session without initially knowing other people were working on it and that it was a shared instance. Unlike some other puzzles (like Divided Is You), it’s fortunately pretty hard to break; I guess I could have gotten really confused and spent all of our comps.

Anyway, once we actually connected with the rest of the group, this was tense but super fun! A lot of my personal puzzle strength lies in being able to solve a wide variety of puzzle types very quickly, and it’s fun to keep switching back and forth between those different sides of my brain. It was a little frustrating to repeatedly have to abandon logic puzzles because we broke them or their time was going to run out; I was involved in two runs, I don’t think we ever got President Reif to pay for his food.

Circular Reasoning

What a great puzzle! The concept is fairly simple, but the execution seems like it was not at all easy for the constructor(s), and given the constraints, the cycles (including the DELTA &lit) all seemed to be pulled off pretty well. And I feel like I’ve now had the same post-solve conversation with folks on half a dozen teams: “So, did you do a search at some point for words with an alphanumeric sum of 44?”

A Collection of Conundrums and Riddles

I joined this puzzle after some teammates had already done the initial steps, including locating the relevant Riddler column. My main contribution was letting everyone know that Bloomberg also has a weekly puzzle column, and that we needed to look at that too. I read both columns sporadically, but somehow hadn’t seen either in advance, and it boggles my mind that both of these (plus the Stata meta crossword) were blatantly signed Barbara Yew; that was a great “this is relevant” confirmation, but I’m surprised that they were out there in advance with a character name that had been pre-advertised.

And apparently we were not the only team that saw “Barbara S. Yew” all over the place and were absolutely convinced that the theme was going to be Baba Is You… to the point where we streamed some gameplay in a social Zoom on Thursday night to introduce it to Setec members who weren’t familiar with it. And yet we still didn’t solve Divided Is You during Hunt.

Filler Puzzle

A bunch of us descended on this all at once after the coin was found and our projection squad unlocked the unexpected bucket of kilo puzzles. At first the answers to the clues appeared to all be three letters (that’s a lot of work to clue EON), but other late ones were clearly longer. We spent a long time looking for flat-style pairings, until someone ID’d one of the names (Theda BARA, maybe?) and we all realized we were dealing with a pile of crosswordese in search of a crossword.

My initial theory was that unlike a normal crossword with mostly good entries and some filler, this grid would be filled with mostly filler and some good entries, which is where the extraction would arise. In fact, when we came to the answer, the fact that it was centrally placed made us confident enough to call it in, which means we never filled in the bottom half of the grid. So that was a lot of unnecessary image identification on the back end.

For Your Eyes Only

I mentioned above in my Cafe Five comments that I’m a sucker for a decathlon (or in this case, triskadeikathlon?) of straightforward mindbenders. I noticed this puzzle was available with nothing in our spreadsheet and asked why no one had done anything, and someone on our team said they’d tried it (and described the general idea) but that they needed to know a lot of codes that they didn’t know. Earlier, before I knew about this puzzle, someone on our team had wondered if the intention of the puzzle was for participants to cheat, so they wrote and asked, and we were definitively told not to. And thank god for that.

Some background: Many of you know that I teach college math for a living. (Fun fact: As I write this, I’m watching an episode of Veep where a character declared that math teachers are terrorists! We’re not.) Exam cheating has always been a disheartening issue, and by disheartening, I mean the single worst aspect of my job. When I created and ran the alt-vocab memorization task Eggsam from the 2014 Hunt, someone showed off in a blog entry that they’d come in with a crib sheet on the inside of a water bottle, and it infuriated me. Since college courses moved online for the pandemic, academic dishonesty has unfortunately become a lot more common across the country; it was incredibly demoralizing over the course of the fall semester, and I’m pretty sure that if a Hunt puzzle had intentionally been about trying to cheat on an online test, it would have broken me and I would have had a much worse opinion of this Hunt as a whole.

So anyway, I was glad to hear that this was a legitimate mental challenge, and it sounded like a blast, so I jumped into the Zoom. On my first run, I was able to solve six mini-puzzles; I actually might have gotten more, but at six I was afraid I was starting to forget the previous answers (not only could you not write things down or look at references to solve puzzles, you also couldn’t write your answers down) so I decided to leave, record what I had, and come back for the rest in 30 minutes when we were allowed to send a representative again. I didn’t notice until I wrote down the answers that the vowels were all binary, and I almost got the right answer right there; I misremembered the total number of puzzles, thought that the answer was ??EINS????O?E?, and called in THE INSIDE COVER. So close…

Going into my second visit and knowing I just needed to know the binary bits, I memorized the Braille and Semaphore for I and O, but I came in at Puzzle 2 (right before a run of four answers I already knew). This meant I had some time to hang around, during which I saw the other solver present clearly looking back and forth at the screen and some kind of reference off-screen; they didn’t seem to be hiding it, so it seemed like they might not have understood the rules. The proctor clearly also saw this, and looked really uncomfortable about how to react. Ostensibly they were there to prevent this behavior, but they looked like the last thing they wanted to do was to confront them. Running Mystery Hunt is a lot of work, and seeing people solve your puzzles should be fun, not massively uncomfortable.

Anyway, my point of all this is that if you cheated at For Your Eyes Only, bite me.

Fun With Sudoku

Loved this puzzle! My eye was drawn to the skyscrapers first, which reminded me a lot of some of the circulant Latin squares I studied for the last math research project I worked on (a talk about minimal Futoshiki cluing for the 2012 Joint Meetings, which, the discrete math fanboy in me has to point out, was cited by Don Knuth). I was able to calculate the correct number of solutions for that puzzle, and I warned Matt, one of our tech gurus who was thinking of auto-solving the individual puzzles, that they would likely have more than one solution, and we might need to count them. He said he could do that by computer too, but I saw the thermo and warned him, no, some of these may have a LOT of solutions. (In that case, probably close to one-sixth of all sudoku solutions.)

While Jackie and I worked on the late puzzles, Matt wrote a program to successfully count the solutions to the first two, though for the third and fourth he just wrote something like “More than 5000.” Then we had two breakthroughs: figuring out that the parentheticals in the final puzzles represented digits, and realizing that if we could figure out what proportion of all sudoku solutions we needed, the total number of sudoku solutions is known and could be altered rather than building the number from the ground up. Jackie, TK, and I worked on the metasudoku while we generated givens and were making steady process, while Matt was working on a solver for the last puzzle; once we had two-thirds of the givens, we were down to under fifty options, and Matt was able to pull the one that generated a word.

While I’d like to think we could have done the math to solve this by hand if we used to, I really enjoyed the teamwork of hacking away at parts of this with programming and parts of it with math; we solved this at a time when we were stalled on a lot of puzzles and I wasn’t feeling very productive, and solving this was fun (as advertised) and revitalizing.

I hate to end on a sour note, but alphabetical order demands it. Jackie and I spent hours solving the slitherlinks on Mobius strips, and that part of the puzzle was great… but we were 100% unable to read the intended letters off of the correct hexagons, and even after seeing what they’re supposed to spell, I can barely read the letters. It doesn’t help that it’s not clear whether you’re meant to read all the fronts then all the backs or front-back-front-back, and how the resulting hexes should be oriented. Given how difficult it is to read the letters, you shouldn’t be trying to read them off of six different hypothetical hexagon sequences. Great puzzle idea, but the execution did not work for me.

Conclusion

Thus concludes my ramblings on Mystery Hunt, and in a sense concludes an incredible year of puzzlehunt content (yes, I know it’s January, but there’s a sizable gap coming up on the puzzlehunt calendar). It’s been frustrating not to have live puzzling events like BAPHL and the NPL convention and of course the Mystery Hunt, as well as not being able to have parties to solve any of the online events with friends in person. But from Penny Park to now, we’ve had two excellent (if overstuffed) Mystery Hunts, as well as great smaller events ranging from Puzzle Boat to Puzzles are Magic to Teammate Hunt to Puzzle Potluck to CRUMS to REDDOT to Labor Day to CMU to UMD. This has been a terrible period for the world, but puzzle folks have worked hard to create excellent content, and I want to thank everybody who’s provided content in the COVID era. Here’s hoping life gets better and puzzles stay awesome.

2021 MIT Mystery Hunt, Part 2: Metas in the Time of Corona

(This is a recap/review of the 2021 MIT Mystery Hunt, which happened this month. Puzzles and solutions can currently be found here. This recap may contain spoilers.)

Here are some comments on some memorable puzzles I worked on in this year’s Hunt (memorable because I liked them, or found them frustrating, or have interesting stores about them, etc.). Naturally it doesn’t include everything I solved or tried to solve. Let’s start with metapuzzles, shall we?

Random Hall

This was a great example of a metapuzzle that was likely inspired by the theme (in this case the dorm name), rather than an independent idea wedged into a round. By the time I looked at it, Philip had already associated the four answers we had with distributions and worked out which columns corresponded to which distributions (with which parameters) but his indices were giving garbage because we were trying to use two letters every time there were two parameters. Eventually I noticed that if we only used the max for our second uniform distribution, we could make the answer end in SPONGES, which felt like a good fit for the meta prompt. But then we were trying to use just the max for all of the uniform spots; eventually it dawned on us that each of the two-parameter disributions happened to occur twice, and we did the right thing and solved with 4/6. Three cheers for a random data generator puzzle that didn’t give me significant Fifty Fifty PTSD.

A while later, Jackie and I returned to the puzzle to try to backsolve the remaining answers and came up with HABITUAL, but then we found that we had solved the puzzle with that answer about twenty minutes after solving the meta… I’m not sure if that was done forward or backward. (Our wild guess for Beta was PRODUCTION PHASE, which was not too far off.)

Student Center

I wasn’t very involved in the other dorm feeder metas… the Dorm Row metas were solved by a bunch of folks in a breakout room that tore through them in sequence like a chainsaw cutting through a sequence of metapuzzles, and I spent a lot of time brainstorming on East Campus without much success. I did get involved with the group working on the overall Student Center, and when someone suggested elements (I forget what got us there, because I’m not sure we noticed the earth/wind/air/fire motif), I immediately came up with what a bunch of the clubs might represent, and in particular, suggesting that the Honor Society might be noble gases was a good way to confirm both the name-length concept and the mechanics for some of the other clubs.

I thought the matching process was just the right difficulty (we made steady progress without feeling stuck, partially through good use of the column filter function on Google Sheets to view all of the students in a certain club), and the extraction worked the way we expected, once we remembered we had a bunch of sets of four students to work with. My only complaint is that, as a Senior Haus alum, I wanted some kind of Sport Death reference to show up in the overall meta answer and hijack the proceedings. (Thanks for putting us in the scavenger hunt, at least.)

Athletics (Basketball, Athletics)

This was probably my most significant contribution to meta solving and thus to our team’s progress. Jeff and I were around when the Basketball meta got opened (thanks to a solve of You Will Explode, I believe), and after brainstorming ideas, I made the prescient comment, “If I were a bunch of nerds who didn’t know anything about basketball, and I had to write a meta about basketball, it would be about Space Jam.” I thought I was joking, but fortunately I checked the Wikipedia article to see which players were in Space Jam, and the teams matching up (including a little Hornets jersey for Muggsy Bogues) confirmed that we were clearly on the right track. I assumed there was a way to match the answers to Nerdlucks, but we never found the hidden characters; we just looked for ways to place the answers so that the index numbers weren’t too high (we were missing the longest answer from Divided Is You that could have gone anywhere), and once we got an SQU at the beginning, we were off to the races.

Since that was our third sports meta solve (you know, in 2007 when we wrote a sports-themed round, people yelled at us), we then opened Athletics, and noticing the unusual letters at the beginnings of answers plus the 5×5 grid, we got to Playfair square pretty quickly. Once we noticed the prime/square/gaps element in the feeder metas, we were able to deduce that the Z must go somewhere in the keyword, somebody noticed that PUZLE would fit nicely (they said it would if PUZZLE only had one Z, but I remembered how you deal with repeated letters in a Playfair keyword), and we managed to get PUZZLE NAMES and then decode our way to the answer with about four missing answers.

Putting everything in the right place in the Playfair felt like a series of leaps of faith… We knew after solving Basketball that we had skipped a step, and I thought it was likely that we skipped one for Athletics too that might tell us in what order we should fill in the primes, squares, etc. But judging from the wrap-up, we were supposed to do the off-the-cuff grid filling that we did. Considering that, this meta feels quite hard to me. Even though it didn’t take us that long once we had it open, I’m curious how this played for other teams.

Giga/Kilo/Milli/Nano

As noted in my previous post, we never made it past the Giga level before it was pity-unlocked for us once Palindrome found the coin. (A member of my team would like to correct me and say that some people did consider that the goal might be to backsolve, but I know that as recently as Sunday I was still saying I didn’t know where we’d submit the answer if we did solve the meta, and nobody corrected me and said the goal was to somehow “solve” Twins. We did understand roughly how the Rule of Three meta should work, and we’d even considered TWIX as a possible feeder answer, which for some reason we called in for two of our unsolved puzzles and yet not the one it actually went with.

When I woke up on Monday morning, we were down to a couple of puzzles (one of which, the Super Mario Maker puzzle, I solved after applying rested eyes to someone else’s partial data; by the way, we did have some team members with MM2, but on principle, throttling a team for hours because they don’t own a particular video game is not cool), and this meta, so in the end everybody was looking at it at the same time. Our big problem was that we essentially refused to move the arrows to positions that didn’t start in the circle’s center… we rotated and scaled all over the place, but didn’t translate them until we got a hint (which suggested “moving” them, which was general enough that it convinced us not to just rotate). I feel like we should have figured this out on our own for two reasons. First, one of the arrows is too long to point to anything from the center; we thought this meant we had to rescale it or point to somewhere else as a final answer, but we should have noticed it was small enough to point from one part of the seal to another. And second, I had already recorded my first multivariable calculus lecture for the semester, which explicitly talked about how the starting point of a vector could be relocated while still representing the same vector.

One of the possible rotations of the arrows sends the long arrow through the Y on the seal and lands on the Harvard Bridge. And of course, even though the bridge is outside the One.MIT circle, there is a name on it. So Galactic, if you’re wondering why you got a few guesses for answers starting with T and associated with Oliver Smoot, that’s what happened.

Clusters

This was the second of the two metapuzzles we had left on Sunday night, and it got solved overnight with help from a hint. This hint mainly just shook us loose from two blind alleys we had hurtled ourselves down to varying degrees. One was noticing (correctly) that the first letters of the puzzle titles were A-G, and instead of viewing this as early entries in two alphabets, some of us decided we should somehow apply flats and sharps to them to form a chromatic scale. I was pretty skeptical of this, although some teammates made the point that “clusters” can refer to a bunch of notes that are close together.

The other was convincing ourselves that the grid-like map of the institute should be used as some sort of crossword grid for entering something (likely the translated answers, which started generating right away). I think I suggested this first and was willing to abandon it, but when someone pointed out that mousing over the puzzles on the round page lit up cluster locations on the grid, it seemed like there was no way we should ignore this setup. Until someone submitted a hint request, and we were basically told that two of the things we were staring at were irrelevant for solving.

There are two entertaining takeaways from this: (1) Our Clusters solve was impacted by tunnel vision, but as far as I’m aware, we had no cluster vision problem on our Tunnels solve. And (2) Setec got stuck on a late meta partially because we DID notice a mouse-over feature on the website. (Revel in that, 2005 Hunters.)

This is getting pretty long already, so I’ll upload what I have and save the non-metapuzzles for a third post.

2021 MIT Mystery Hunt, Part 1: Whoosh Big Picture Pros and Cons Nyeeeow

(This is a recap/review of the 2021 MIT Mystery Hunt, which happened this month. Puzzles and solutions can currently be found here. This recap may contain spoilers.)

I’ve gotten some sleep now. Disclaimer: I want to get some Mystery Hunt posts on the record (and give people a forum to comment on the Hunt if this is where they want to do that), but after that, Puzzlvaria will likely be mostly dark for a while. Brown’s semester begins today, so I’m kicking off another period of online teaching, which is challenging in itself, but we’re also expecting a baby boy in March, which will make things exponentially harder.

How parenting will ultimately affect my puzzlehunt bandwidth is certainly not the biggest concern when it comes to raising a child… but for me, it’s not the smallest one either. I’m sure that balance will come up as a topic moving forward on this blog. But for the immediate future, my sporadic posting schedule will probably become even more sporadic. The upcoming puzzlehunt calendar is a lot leaner than in recent months anyway, so there may not be as much to cover.

This year’s Mystery Hunt was a monumental achievement on multiple levels. Even without the constraints of the pandemic, there were some excellent puzzles and metapuzzles, and the “projection device” MMO is the kind of big idea that I would have vetoed out of the gate for being completely unfeasible. Certainly, when we solved the opening meta and watched the video explaining the projection device, my instinctive reaction was, “This is going to crash constantly.” But to Galactic’s credit, apart from some hiccups when the device was time unlocked and thousands of people gained access at once, the thing worked pretty consistently, and certainly more reliably than Cyberpunk 2077. It was also not just a collection of bells and whistles spread on top of a “traditional” Hunt, with unlocks/events/runarounds happening within the virtual world in a variety of creative ways (although I didn’t become aware of a lot of these until wrap-up, which is an issue I’ll talk about). And even though Galactic’s MMO idea pre-dated the need to put the Hunt entirely online, ultimately it allowed for the best possible remote Hunt experience, especially with all the loving MIT-specific detail invested into the virtual campus.

Back in the day, there was a rule of thumb that teams should consider not totally reinventing the wheel in their first Mystery Hunt, since Hunts are hard to write without introducing unpredictable variables, and then experiment if/when they win again. In a certain sense, Old School Setec (2000/2002), New School Setec (2017/2019), Random/Metaphysical Plant (2006/2011), and Evil Midnight (2007/2009) all did this, with the level of second-hunt innovation relative to the era. Left Out made bold choices out of the gate last year (at least in terms of round structure), and Galactic made even bolder ones, and both were astonishingly successful.

I plan to talk about some puzzles and metapuzzles I participated in solving (and have opinions about) in a later post, but while I’m in big-picture mode, I want to take a deep dive on two concerns I had about this Hunt (and perhaps past and future Hunts), despite being so impressed by it; one, which Galactic had minimal control over, is isolation, and the other, which they did, is Hunt size.

Isolation

Setec usually has a handful of remote solvers, but not enough to warrant full audio/video chat capabilities; in recent years for both solving and writing, we’ve used Slack for most discussion, and an organizational platform wired into both Google Sheets and Slack channels. In a typical year, most of this is intended to make sure information doesn’t get lost between solving sessions, and to allow people to look at and edit spreadsheets on their own screens, although in a lot of cases those people are across the table from each other and can actually speak in meatspace.

For this year, we used Slack plus Zoom, with most of our co-solving interactions happening in breakout rooms. Shifting puzzle-solving from in-person to breakout rooms has a lot of the same drawbacks as shifting classroom math collaboration from in-person to breakout rooms. When you’re in your portion of a physical room, you hear a lot of ambient noise from other groups; that noise can be distracting, but it also makes you aware that other groups are doing things, and as an instructor, I rely on that general sound of the room to know whom I should probably check on. But in a breakout room, you have zero A/V from other groups until you leave the room, so it’s like erecting a ton of completely impenetrable walls in the middle of your HQ. There were a few times when Jackie and I jumped into a breakout room to work on a logic puzzle, and after an hour I’d realize that the entire team could have given up and gone home and we wouldn’t notice, because they were totally invisible to us from inside the breakout room. It was hard to feel part of a team at those times, and I’d sometimes park myself in our Zoom “lobby” just for the human contact.

There was also a self-inflicted element to this isolation; early in the period that the projection device was available, I puttered around the Green Building for a few minutes, unlocked a couple of puzzles, but then swooped on some puzzles and didn’t really look back much. Then throughout the rest of Hunt I heard people saying there were puzzles available to unlock or “field goals” that needed to be done, but I always figured these would be more easily carried about by people who had been paying attention to the projection world, and I should stick to what I’m good at, puzzles. Bu this means that just like I couldn’t hear what was going on in the other breakout rooms, I couldn’t hear what was happening inside the projection device. For me it was mostly a black box… other people went in, puzzles came out. And as someone who usually thrives on having a good mental picture of how the Hunt fits together, I frequently did not.

During the endgame, I actually did have a reason to walk around the projection device, and I found it a lot more user-friendly than I’d expected. I think it still would have been tough to be an “unlocker” without diverting a lot of “traditional” puzzle-solving time to navigating PerpIW. I’m still not sure if I would have been happier making that trade, but my experiences certainly left me feeling like I was missing big chunks of the Hunt. And I’m curious how things were for a small casual team that couldn’t devote some people to navigation and others to puzzle-solving. Though for such a team, I imagine there were bigger problems, with emphasis on “big”…

Hunt Size

Devoted Puzzlvarians will remember that I was shell-shocked by my experience of not finishing the 2020 Hunt, and while I thought said Hunt was very well-written, I also thought it was too long. Setec did finish the 2021 Hunt, although we cut it about as close as one could, finishing our last meta (Giga/Nano) at around 9:30am ET on Monday, before the cutoff time of 10am. So did finishing this year make me feel like the size was better calibrated? Nope. In 2020, on Sunday evening when Hunt wrapped up, we were stuck on one meta where we’d solved a big chunk of the round (Cascade Bay) and one where we’d only scratched the surface (Cactus Canyon). This year, we really only finished because none of us had to travel home, and we were able to solve (in shifts, of course) through Monday morning. As for Sunday evening, we were stuck on… one meta where we’d solved a big chunk of the round (Clusters) and one where we’d only scratched the surface. As it happened, we didn’t know about the surface-scratching part until Palindrome found the coin, since we didn’t understand the Giga structure and had no idea there were additional levels below it. We were apparently not the only team to have this issue.

So in a typical year, this Hunt would have run just as “long” as last year’s, and Galactic wouldn’t have come close to their goal of 10+ teams finishing, though that goal may have been based on a hunt-until-Monday assumption.

I’ve been spending a lot of time yammering in the Puzzlers Club Discord recently, and there was an interesting brief discussion of the “epochs” that the Mystery Hunt can be separated into. There’s innovation in every Hunt, but I argued that the key turning points for me are 1998 (rounds and unlocking rather than having all the puzzles at once), 2002 (structure heavily influenced by theme), 2009 (significant variation of structure between rounds), and 2018 (Hunt size and completion time go way up). The more I think about this, the more I think there were two big influences to the Hunt blowing up from 2018 on.

One was, of course, the 2017 Hunt and teams not wanting to repeat the surprise of having a team find the coin Saturday morning. (I know many teams were totally fine with the 2017 Hunt and the fact that it allowed way more teams to reach the endgame. I personally would have liked it to run a bit longer for the top teams, and whether you agree with that or not, having the coin found way before the construction team expects is not the best experience.) Another was the fact that Galactic Puzzle Hunt debuted in 2017; I believe this was a direct result of the 2017 Hunt, since Galactic found themselves with a free Sunday to start writing a kickass puzzle hunt.

The Mystery Hunt always had something of a reputation for puzzle types and interactivity and nefariousness that didn’t show up in any other puzzle hunts (there are immersive puzzle experiences that only show up in The Game, but those feel extreme on a different axis). I believe that GPH was the first online hunt to really start pushing that envelope. It showed you could have online puzzles with crazy procedurally generated elements (man, do I love Ministry of Word Searches) and teamwide interactivity and messing with expectations like team standings and answer submission. Teammate did a great job in their hunt this fall following in those footsteps, and even hunts like the My Little Pony hunt and Puzzle Potluck did ambitious things this year with metapuzzles and structure and plot twists. (Incidentally, have I told people to solve UMD Puzzlehunt from a few weeks ago? Run, don’t walk. It was excellent and came totally out of left field.)

Anyway, I love GPH and hope it will continue to push boundaries in its own lovely way. But as it pushes boundaries, the expectation of what can only happen in Mystery Hunt gets higher, both in terms of individual puzzle complexity and scope of the Hunt itself. And between that and teams erring on the side of not ending too quickly, recent Hunts have only been solvable in a weekend if your team is huge. And then your huge team feels like it needs to cater to other huge teams, and pretty soon there are only half a dozen teams that are really in contention not just to win, but even to see the whole Hunt.

I’m very curious about the experience of small casual teams (especially student teams new to puzzling) in this Hunt. I had a great time, but I had 59 teammates handling the bits I couldn’t or didn’t have the time for. This Hunt had a very friendly opening round that I’d expect small teams to be able to handle, but by Friday evening everybody had been thrown into the deep end, and the organization of what was ahead did not become clear for quite a while. 112 teams solved a metapuzzle, which is fantastic, but did those teams feel like they really experienced this Hunt? Maybe they did, and I hope they did. But at the current trajectory of Hunt size, I’m not sure a team off the street can make a dent in the puzzle structure, and that’s not great for sustainability (both from a writing perspective, and from a perspective of serving the Hunt’s intended audience, and as much as the puzzling community would like to claim ownership, as long as MIT is hosting the event, that audience is the MIT community and especially MIT students).

Okay, I think I’ve said enough controversial stuff to get people sniping at each other in the comments. I’ll post at least once more talking about puzzles I liked (and at least one that I literally ripped into tiny pieces out of frustration). For now, tell us what you thought about Hunt and/or about my thoughts if you’d like to. And somebody generate the team progress vs. guessing graph, because I’m sure I’ll have opinions about that again! (Five minutes? You call that throttling?)
