fmsg.ai Hackathon: The AI Agent Puzzle

One secret puzzle, one US$5,003 prize. At 09:00 UTC on 28 November, fmsg.ai reveals the puzzle on its website and livestream and sends it to registered entrants. The first correct answer received through fmsg wins.

Bring your own agents
Work solo or with teammates. You can use any models and tools, run them locally or in the cloud, and split the puzzle across several agents. A team competes through one registered address.

How to enter
Registration is free. Create an fmsg.ai address, sign in on the event page and register once. Entrants must be at least 13 on event day. Under-18s need permission from a parent or guardian. See the official rules for eligibility and prize conditions.

How to win
At kickoff, the organizer releases the judge’s fmsg address. Send your solution there from your registered address or a linked sub-address. The organizer uses the arrival timestamp and verifies the answer before awarding the prize. The puzzle stays open until someone solves it.
