2019 MIT Mystery Hunt

Greetings puzzlers!

Setec Astronomy is surprised and pleased to announce that the 39th annual MIT Mystery Hunt will begin at noon on Friday, January 18, 2019. Hunt will end at 5:00 pm on Sunday or when the coin is found, whichever is later. Wrap-up will take place at noon on Monday. We look forward to a fun-filled weekend of puzzles!

Team Registration

Registration for the 2019 MIT Mystery Hunt is now open. We strongly encourage all teams to register by the end of December. If you plan to request room space on the MIT campus, you must register by December 15. Please register only once per team. The registration form is available here.

As in the past, there is no formal limit on team size, but we recommend you keep your teams to a maximum of 75 people. The 2019 Hunt will have mechanisms in place to ensure smaller teams are having fun and making progress, but if your team is well over 75 strong, you might have less fun. During our 2017 Monsters et Manus Hunt, some competitive teams found that they gained access to a huge number of puzzles at once. That will not be the case this year; teams in contention to finish first will likely have access to at most 12–15 puzzles at once, and experienced teams should take this into account when deciding on team size to ensure an experience that everyone will enjoy.

Unattached Hunters

If you would like to participate in Hunt but are not currently a member of a team, we can help match you up with a team that is welcoming unattached hunters. Please fill out this form by the end of December.


As always, Hunt is an MIT event and is best experienced in person at the Institute. For those who are coming from out of town, we have arranged discounted room blocks at several local hotels—the Marriott Kendall Square, the Hyatt Regency, Le Méridien, the Royal Sonesta, and the Kendall Hotel. Details are available here. When planning your accommodations, please keep in mind that headquarters will be open until 5:00 pm on Sunday, January 20.
