The “hydra” we’re coping with is a metapuzzle: We have now to discover a means to make use of the options from different puzzles that we’ve already solved to extract yet one more reply. If we clear up this one, we’ll be rewarded with extra puzzles.
We all know we have to diagram the solutions for this spherical of puzzles as a binary tree. In step with the hydra metapuzzle’s mythological analogue, each time we clear up one puzzle, two extra department off till we’ve got a diagram 5 ranges deep. We’re nonetheless lacking solutions from a number of unsolved puzzles that might assist us work out how the diagram works and tips on how to extract a solution to the metapuzzle. The diagram we’ve drawn, in inexperienced chalk, will get extra chaotic with each addition, erasure, and annotation we squeeze onto the overcrowded chalkboard. However we are able to sense that we’re only one “aha!” away from an answer.
MIT’s Thriller Hunt has been difficult puzzle lovers yearly since Brad Schaefer ’78, PhD ’83, wrote 12 “subclues” on a single sheet of paper as a problem for buddies throughout Impartial Actions Interval (IAP) in 1981. The solutions led solvers to an Indian Head penny he had hidden on campus. At present’s Hunts are nonetheless constructed round that primary idea, however what constitutes a problem has modified over 4 a long time. One of many clues from the unique 1981 Hunt is only a lacking phrase in a quote: “He that performs the king shall be _____; his majesty shall have tribute of me.” It’s simple to resolve at the moment with Google, however in 1981, even when you knew it was Shakespeare, when you didn’t discover the delicate trace that you must search for a personality referring to a play throughout the play, it may need taken a number of hours of skimming the Bard’s collected works to seek out the reply.

We add a number of extra options to the hydra diagram over the following few hours. Finally somebody notices that every one the solutions within the fifth degree of the diagram appear to have an odd prevalence of Ls and Rs. That is the “aha!” second: They inform us tips on how to navigate the binary tree. From the primary node on the prime of the tree, we comply with the Ls and Rs within the order they seem in every of the 16 options on the fifth degree. Take the left department, then proper, then left once more, touchdown on a phrase that begins with H. The second fifth-level reply leads us to a phrase that begins with E. Repeating the method with all 16 solutions spells out an apt strategy to cope with a hydra: “HEADTOHEADBATTLE.” (Puzzle options are historically written in all caps with no areas or punctuation.) These of us who’ve been tackling the puzzle take a second to take pleasure in our victory earlier than splitting as much as discover new puzzles to work on.
Some components of the Thriller Hunt are laborious to explain, the type of must-be-seen ingenuity that additionally evokes hacks on the Nice Dome and any variety of above-and-beyond engineering initiatives showcased round campus yearly. Many of the puzzles are totally distinctive, though they do usually incorporate logic and phrase issues in addition to extra mainstream components like crosswords, sudoku, and Wordle. However virtually something could be become a puzzle. For instance, chess puzzles is likely to be mixed with the cardboard recreation Magic: The Gathering. Or solvers could possibly be requested to arrange a Git repository with 10,000 out-of-order commits (that’s, discover the proper sequence of 10,000 adjustments to a file because it was tracked in a model management system), determine duets from musicals, or draw on their data of popular culture trivia.
For many of its historical past, the Thriller Hunt had little official standing on campus. By custom as a lot as any organizational effort, groups merely confirmed up in Foyer 7 on the Friday earlier than the Martin Luther King Jr. vacation for the kickoff. In 2014, the MIT Puzzle Membership was fashioned to assist present year-to-year continuity and different assist, equivalent to securing rooms for groups to work in and reserving Kresge Auditorium for the opening ceremonies. Puzzle Membership additionally hosts different occasions, equivalent to mini puzzle hunts and sudoku and logic puzzle competitions—which Becca Chang ’26, the membership’s present president, says “has helped rather a lot with outreach to new college students or anybody who is likely to be serious about [puzzles].”
Expertise has enabled the Thriller Hunt to develop and evolve in important methods, and never simply by way of the sorts of puzzles which might be doable. By the mid-Nineties, a single particular person might tackle the accountability of writing and operating the occasion. At present it’s a yearlong dedication for the successful group to design the following 12 months’s Hunt. Doing so requires managing artistic output and technological infrastructure that rival these of a small enterprise. Duties embrace spending 1000’s of hours writing and testing puzzles, developing bodily puzzles and props, and constructing a dynamic web site that may face up to the large inflow of puzzle-hungry guests.

Simply organizing a group of solvers is usually a main enterprise, particularly now that an increasing number of individuals are becoming a member of remotely. Anjali Tripathi ’09, who began the group I’m Not a Planet Both in 2015, received her introduction to puzzle hunts via a miniature Thriller Hunt that Simmons Corridor runs for first-years. After tackling the principle occasion with the Simmons group on campus as an undergrad, she participated remotely for the primary time in 2010. “I used to be overseas in England and nonetheless wished to do Hunt, and I bear in mind how laborious that was,” she says. The group “had no infrastructure for it.”
