This game is for two players only. Start by drawing a tic-tac-toe grid like the one shown below. Choose who goes first. That person can choose to be X's or O's. We'll assume player 1 is X's. They begin by placing an X in any of the nine squares. Player two then places an O in any of the remaining eight squares. The game continues until one player scores three X's or O's in a row thus winning the game. If neither player scores three in a row and all nine squares are filled then it is considered a "cat's game" or a tie. Play as many times as you like.
