Checkmate the other king: attack it so that it has no safe square. Play the computer at three levels, as White or Black, or a friend on this device.
- Castling, en passant and promotion are played for you when they are legal; every illegal move is refused.
- A game is drawn by stalemate, threefold repetition, the fifty-move rule or too little material to mate.
- Against the computer, Undo takes back its reply and your move together.
- Casual makes human mistakes, Challenge looks a few moves ahead and Expert thinks longest.
