Objective
Be the first player to place three of your marks in a straight line on the 3x3 board. X goes first, O goes second, and every square can hold only one mark.
How to Play
- Choose online play or play against the computer.
- On your turn, click any empty square to place your mark.
- Against the computer, you are X and the computer is O.
How to Win
You win by making a row of three across, down, or diagonally. The game ends as soon as a player completes a line. If all nine squares are filled and nobody has three in a row, the game is a draw.
Tips
- The center square is powerful because it helps many lines.
- Block your opponent when they have two marks in a row.
- Try to create two possible winning lines at once.
