I’m part of a team of puzzlers who spent most of last year writing LOTS of puzzles for the annual MIT Mystery Hunt (http://web.mit.edu/puzzle/www/history.html), which was this year Alice In Wonderland themed (with other Carrollian and non-Carrollian touches).
We had also noticed the call for puzzles here last June, but we were unable to participate as our writing process is very (almost comically) secretive, and the puzzles and theme were not to be revealed until the weekend of the recent Hunt.
A number of the puzzles we wrote require specific knowledge about MIT, and some aren’t strongly integrated into the theme, though they may still be of interest to you. The entire hunt, including all puzzles and solutions, can be found at the following address: http://web.mit.edu/puzzle/www/2014
If you have any further questions about specific puzzles or would like to contact the author(s) directly, please feel free to email the team leadership at firstname.lastname@example.org . Enjoy!
