PUZZLE · YOU VS COMPUTER
Tic Tac Toe
Place three X marks in a row horizontally, vertically, or diagonally before the computer does the same with O.
How to play
You play X and move first. Select any empty square. Wait for the computer to place its O before choosing again.
A useful tip
Block an opponent’s line of two. The center and corners are useful starting positions.
Another round: A full board with no winner is a draw. New game starts a rematch.
