Puzzle Hunts

SUMO hosts a puzzle hunt open to all Stanford students. We invite you to solve puzzles as quickly as possible for prizes while having fun!

Puzzle Hunt 2019

Registration is closed. Thanks for a great puzzle hunt this year!

What is a puzzle hunt?

It is a fun, interactive event in which teams of players race to solve creative puzzles at different locations around campus. You will be given puzzles at each location and submit answers via an app. If you have trouble, we'll be on-site to help out!

No prior experience is needed.


Register in teams of 1-4 people! Anyone from the Stanford community is eligible to participate, but only Stanford students can receive prizes. Note that we do have limited capacity, so registration is first-come first-served.


The puzzlehunt will occur from 11am to 5pm or whenever your team finishes the puzzles. Lunch will be provided. We will send out more details about the hunt to the registered participants via email.
