You always begin by placing a piece, black-side up, adjacent to a white piece and opposite another black piece, so that a line of one or more white pieces directly intervenes (horizontally, vertically or diagonally) between the two black pieces.

When you place a piece so that an adjacent white piece is between two blacks, the white piece is "surrendered," or flipped over to black. You may capture one or more pieces on a given turn. Also, you may capture any number of your opponent's pieces in one or more rows diagonally, vertically and horizontally. Note that these pieces may be flipped and change hands many times during a game.

If you cannot make a legal move, you automatically pass your turn to computer, if it can make a legal move. This continues until you have a legal move available. The computer does not allow you to make any illegal moves.

You win if you have the most pieces on the board at the end of the game. Or you may also win by completely eradicating computer's color from the game board.
