Start at 1,200 Elo. Winning raises your rating; losing lowers it. Beating a stronger player earns more points. Draws adjust ratings toward an equal result. Two equally rated players gain or lose 16 points for a decisive game.

Only completed online games between named players count. Ratings update once per game. Ranked by rating, then wins; fewer games breaks the next tie. Solo and same-device games are not rated.
