Put a disc where it traps a straight line of the other color between your new disc and one of yours. Every trapped disc flips to your color. You must trap something, in any direction, or you lose your turn. When the board is full or nobody can move, the color with more discs wins. Corners are gold: a disc in a corner can never be flipped.
