Classic chess, full standard rules. Play a friend online with challenges, a rating and match history, take on the built-in computer, or pass-and-play on one device.
Challenge a friend by name or code, or anyone in the lobby. A ready-check on both sides, a 10-minute clock each, and every result feeds a separate chess rating.
A built-in engine that plays a solid, quick game entirely in your browser — no huge download, no Stockfish, no server.
One board, one device, no sign-in. The board flips for whoever's turn it is.
Castling, en passant, promotion, and every draw condition — stalemate, threefold repetition, the 50-move rule and insufficient material.
