The game proceeds until neither player wishes to make another move. Once placed on the board, stones may not be moved, but stones are removed from the board if the stone (or group of stones) is surrounded by opposing stones on all orthogonally adjacent points, in which case the stone or group is captured. The players take turns placing the stones on the vacant intersections ( points) of a board. One player uses the white stones and the other, black.
