The “hydra” we’re coping with is a metapuzzle: We’ve got to discover a approach to make use of the options from different puzzles that we’ve already solved to extract another 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 now have 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 learn 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 fans yearly since Brad Schaefer ’78, PhD ’83, wrote 12 “subclues” on a single sheet of paper as a problem for mates throughout Impartial Actions Interval (IAP) in 1981. The solutions led solvers to an Indian Head penny he had hidden on campus. At this time’s Hunts are nonetheless constructed round that primary 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 at the moment with Google, however in 1981, even for those who knew it was Shakespeare, for those who didn’t discover the delicate trace that it’s best to 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. Ultimately somebody notices that each 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 learn how to navigate the binary tree. From the primary node on the high of the tree, we observe 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 method 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 type of must-be-seen ingenuity that additionally conjures up 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 virtually something may be became a puzzle. For instance, chess puzzles is likely to be mixed with the cardboard sport Magic: The Gathering. Or solvers may very well be requested to prepare a Git repository with 10,000 out-of-order commits (that’s, discover the proper sequence of 10,000 modifications 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, comparable to securing rooms for groups to work in and reserving Kresge Auditorium for the opening ceremonies. Puzzle Membership additionally hosts different occasions, comparable to mini puzzle hunts and sudoku and logic puzzle competitions—which Becca Chang ’26, the membership’s present president, says “has helped so much with outreach to new college students or anybody who is likely to be concerned about [puzzles].”
Expertise 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 potential. Via the mid-Nineties, a single individual may tackle the accountability of writing and operating the occasion. At this time it’s a yearlong dedication for the successful staff to design the following yr’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, setting up 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 staff of solvers is usually a main endeavor, particularly now that increasingly contributors are becoming a member of remotely. Anjali Tripathi ’09, who began the staff I’m Not a Planet Both in 2015, bought her introduction to puzzle hunts via a miniature Thriller Hunt that Simmons Corridor runs for first-years. After tackling the primary 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 needed to do Hunt, and I keep in mind how laborious that was,” she says. The staff “had no infrastructure for it.”
