How do you play chess online against the computer?

Tap one of your pieces to highlight its legal moves, then tap the target square. Full chess rules apply: castling, en passant and pawn promotion. There are three difficulty levels — easy, medium and hard — and the "Play black" button flips the board and lets the computer move first.

When does a chess game end?

A game ends with checkmate (a win), stalemate (a draw), or a draw by the 50-move rule, threefold repetition of the position, or insufficient mating material. The leaderboard ranks the fastest checkmates — the fewer moves you need, the higher you place, separately for each difficulty level.
