Play the engine across five levels, pass one phone back and forth with a friend, or play someone on another device with a game code. Every rule in the book. Free to play, with non-personalized ads.
From a beginner that overlooks things to a full-strength search that will outcalculate most club players. Pick the one that gives you a game.
Castling, en passant, under-promotion, stalemate, threefold repetition, the fifty-move rule and insufficient material. All of it.
Playing the engine and two-player games need no account and no internet at all. Only the online mode goes near a network.
Continue with Apple, Google, or a Guest profile, create a game, and send the five-character code. Moves appear on both devices as they are played.
Undo, a hint that runs a real search, board coordinates, five board themes, light and dark, and a clock if you want one.
