Tic tac toe is a game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who first succeeds in placing three of their marks in a diagonal, horizontal, or vertical row is the winner. Sometimes you get in a draw with your opponent if all the grid is filled. It also allows you to play repeatedly by clicking the reset button.
