Blitz leaderboard

Quick games with fewer pieces: the fast rule set for a break, decided in a few minutes.

How the ratings work

Every player starts at 1200. A ranked game online moves both ratings with the Elo formula: beating a stronger opponent earns more, losing to a weaker one costs more. A rating marked ^? is provisional, the player has fewer than 10 ranked games. Games against the computer never change the rating, but a win against the God level counts on its own board, and the server replays every reported game move by move before it counts.

Ranked games need a free account (a passkey or Google, no e-mail or password). Everyone else can still play, watch and read these boards.
