All instructions
Play Reversi: trap a straight line of opponent discs between your new disc and an existing one to flip them. Lines can run horizontally, vertically or diagonally. Black moves first; against the computer you play black. A player with no legal move passes automatically. The game ends when neither side can move, and the most discs wins. Choose a casual or clever local computer, or two players on the same device. Tap a legal square, or use arrow keys and Enter or Space. Undo turn reverses your move and the computer reply.
