MIT has just made the puzzles from last week's Mystery Hunt public. You can see all the puzzles if you click the "Public Access" link on that page and then look through the Rounds dropdown menu.
I always enjoy picking through the MIT Mystery Hunt and seeing how much I can figure out. The answer is always "very little" because the puzzles are meant to be solved by teams of 30+ people working in shifts, and I heard that this year's hunt went long so the puzzles were probably especially hard this year. I'm happy if I can even recognise what a puzzle is about. I just like to admire the ridiculous hoops you're expected to jump through for some of these puzzles.
I've only looked at the Atrium round so far and all the puzzles have kicked my ass, but I feel like Cohost users might like the idea behind You're Telling Me. (I think that link will 404 unless you use the Public Access login link earlier in this post first.)
picking through these now, here's some other ones that catch my eye:

https://interestingthings.museum/puzzles/nuclear-words (edit: I didn't notice until just now, but I'm pretty sure this is a metapuzzle, so while it looks cool you're not gonna be able to do much with it unless you have all the answers from the other puzzles in the Science Center round)
