Red is trying to make Xs and white is trying to make Os. Two game pieces - white, red, or both - must be used to make a mark. Your goal is to get three-in-a-row of your mark, vertically, horizontally, diagonally, or semi-diagonally. Play all the game pieces without a win? It's not a cat's game. It's time for phase two! Take turns flipping your game pieces over until someone wins! Ages 8+
