The “hydra” we’re coping with is a metapuzzle: We’ve got to discover a manner to make use of the options from different puzzles that we’ve already solved to extract yet another reply. If we remedy 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 remedy one puzzle, two extra department off till we have now a diagram 5 ranges deep. We’re nonetheless lacking solutions from a number of unsolved puzzles that might assist us determine how the diagram works and 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 will sense that we’re only one “aha!” away from an answer.
MIT’s Thriller Hunt has been difficult puzzle fans yearly since Brad Schaefer ’78, PhD ’83, wrote 12 “subclues” on a single sheet of paper as a problem for associates throughout Unbiased Actions Interval (IAP) in 1981. The solutions led solvers to an Indian Head penny he had hidden on campus. In the present day’s Hunts are nonetheless constructed round that fundamental idea, however what constitutes a problem has modified over 4 many years. 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 straightforward to resolve in the present day with Google, however in 1981, even when you knew it was Shakespeare, when you didn’t discover the delicate trace that it’s best to search for a personality referring to a play inside the play, it might need taken a number of hours of skimming the Bard’s collected works to search out the reply.

We add a number of extra options to the hydra diagram over the following few hours. Ultimately somebody notices that every one the solutions within the fifth stage of the diagram appear to have an odd prevalence of Ls and Rs. That is the “aha!” second: They inform us navigate the binary tree. From the primary node on the prime of the tree, we observe the Ls and Rs within the order they seem in every of the 16 options on the fifth stage. 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 option to take care of 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 parts of the Thriller Hunt are laborious to explain, the form 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. A lot of the puzzles are completely distinctive, though they do typically incorporate logic and phrase issues in addition to extra mainstream parts like crosswords, sudoku, and Wordle. However nearly something may be changed into a puzzle. For instance, chess puzzles is likely to be mixed with the cardboard recreation Magic: The Gathering. Or solvers might be requested to prepare 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), establish duets from musicals, or draw on their information 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, reminiscent of securing rooms for groups to work in and reserving Kresge Auditorium for the opening ceremonies. Puzzle Membership additionally hosts different occasions, reminiscent of 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 fascinated with [puzzles].”
Know-how has enabled the Thriller Hunt to develop and evolve in vital methods, and never simply when it comes to the sorts of puzzles which can be doable. By means of the mid-Nineteen Nineties, a single particular person might tackle the accountability of writing and operating the occasion. In the present day it’s a yearlong dedication for the profitable staff to design the following 12 months’s Hunt. Doing so requires managing inventive output and technological infrastructure that rival these of a small enterprise. Duties embrace spending hundreds of hours writing and testing puzzles, establishing bodily puzzles and props, and constructing a dynamic web site that may stand up to the massive inflow of puzzle-hungry guests.

Simply organizing a staff of solvers generally is a main enterprise, particularly now that increasingly individuals are becoming a member of remotely. Anjali Tripathi ’09, who began the staff I’m Not a Planet Both in 2015, obtained her introduction to puzzle hunts by means of a miniature Thriller Hunt that Simmons Corridor runs for first-years. After tackling the principle occasion with the Simmons staff 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 staff “had no infrastructure for it.”
