The rules of Tic Tac Toe are simple: players take turns placing their mark (either an X or an O) in one of the nine squares of a 3x3 grid. The first player to align three of their marks in a horizontal, vertical, or diagonal row wins the game. If all nine squares are filled without anyone achieving three in a row, the game ends in a draw. To play, simply click on an empty square to place your symbol and try to outmaneuver your opponent or the AI. Tap play to open the full game.
