WATCHLIST is a 24-hour online Jeopardy CTF about digital investigation: forensics, OSINT, recon, and the hands-on work investigators actually do. It's a love letter to Person of Interest, narrated by The Machine.

There are 24 challenges across 6 categories: Forensics, Lab, OSINT, Recon, Trivia, and a Person of Interest story track that unlocks as you play.

It's made for beginners through intermediate players, so there's an easy way in and the difficulty climbs from there. Every challenge teaches a real, usable skill with tools people actually use, and the hints are written to teach you something, not just hand over the answer.

A few quick things:

Any tools are fine, including AI. They're helpers, not shortcuts, and they won't finish a challenge for you.
Teams of 1 to 6, and solo players are very welcome.
Free to play.

Prizes: $750 / $500 / $250 for the top three.

When: 19 September 2026, 03:30 UTC. Runs for 24 hours.
