CMU Fall 2025 Puzzle Hunt

What are the puzzles like?

There are a huge variety of puzzle types, like wordplay, logic, or multimedia. For examples of the kinds of puzzles we'll give you, check out our Past Hunts.

How do I solve a puzzle?

Every answer to a puzzle is an English word or phrase. When you think you have the correct answer, type it into the answer box on the puzzle page.

But be careful about guessing too much if you're not sure of the answer. If you submit too many incorrect guesses for the same puzzle within a short amount of time, our server will rate-limit your guesses. When this happens, please wait before submitting again.

How do I register?

Register your team of six (or fewer if you want) here!

What do I need?

• A team of no more than six people.
• A laptop, phone, or other device with internet access. You'll need this to register, view puzzles, and submit your answers.
• Paper and pencil may be useful for scratch work.

How long will it last?

The hunt will run from November 14th 07:00PM to November 16th 04:00PM EST.

I think there is an error in this puzzle.

You can contact the staff at puzzlehunt-staff@lists.andrew.cmu.edu. If there is in fact an error, we will make an announcement to everyone.

Is there anything else I should know?

Nothing on this and the registration page is a puzzle crucial for completing the hunt. No, really, this is not a puzzle.

Wait, I have more questions!

Email puzzlehunt-staff@lists.andrew.cmu.edu with "Puzzle Hunt" somewhere in the subject line.
