Rank · Rating
Ranked games require two signed-in members, at least 8 moves and 15 seconds. The first 3 games per opponent and ruleset each UTC day count. Elo starts at 1000 (K=32); draws count as half a point. Win rate is wins divided by all ranked games. AI, guest, self-play and aborted games are excluded. Only public profiles appear. Rankings start with this feature; old results are not retroactively rated.
