Classic 3x3 Game

Classic TicTacToe supports one player and two player gameplay, so you can play against your phone or against your friend.

Tic-tac-toe (or Noughts and crosses, Xs and Os) is a pencil-and-paper game for two players, X and O, who take turns marking the spaces in a 3×3 grid. The player who succeeds in placing three respective marks in a horizontal, vertical, or diagonal row wins the game.
