Once a year hundreds of MIT students, alumni, and puzzle enthusiasts converge in Cambridge for a weekend of almost impossible puzzles, tied together under a light narrative theme. In the five years I’ve been participating in the MIT Mystery Hunt, teams have been asked to turn to puzzles to put on a Broadway musical, rob a bank, save Wonderland, and explore the ocean’s depths. Progress at the Mystery Hunt is driven by tackling meta-puzzles: puzzles that leverage solutions from a group of puzzles as elements of a larger puzzle. The 2016 Hunt prominently featured its elegantly crafted meta-puzzles, delivering a master-class in solid puzzle design.
This article will explore some of those puzzle design choices. In order to discuss those choices, it will be necessary to “spoil” the answers to quite a few puzzles in the Hunt, so read at your own risk. If you want to try your hand at the Hunt spoiler-free, stop reading now and explore the 2016 Hunt website, which conveniently features detailed solutions to every puzzle in the hunt alongside the puzzles themselves.
Theming and the Meta-Puzzle: The Red Herring
Every MIT Mystery Hunt starts with a kick-off event that introduces the year’s theme. This year, kickoff attendees were informed that the 64 participating teams were competing for the top spot in a Dog Show. Sure, there were a few glitches during kickoff. Slides showing scores to future football games…PowerPoint slides responding to questions from the presenter…all clearly red herrings. The 2016 Mystery Hunt was going to be all about cute, adorable puppies competing.
