How a race plays out

  1. 01

    Step up

    Hit “Find a race.” We match you with someone close to your rating, usually in seconds.

  2. 02

    Face off

    Cameras and mics on. Same Codeforces problem, same 40-minute clock, side by side.

  3. 03

    Get judged

    Submit on Codeforces. Verdicts come straight from the judge — never self-reported.

  4. 04

    Climb or cope

    First accepted verdict takes the round. Elo moves for both of you the moment it’s over.

Voice and video, built in

A live call runs next to the editor the whole race. Catch these bars to their face, not a chat box.

A real Elo ladder

Provisional K-factor for your first ten races, standard after. A number that actually means something.

Codeforces-verified

No manual grading, no honor system. We poll your submission and trust whatever the judge says back.
