How to play
- Players take turns putting their mark — X or O — in an empty square.
- The first to get three in a row (across, down or diagonally) wins the round.
- If all nine squares are filled with no winner, the round is a tie.
- Against the Unbeatable computer, the best you can do is a tie — can you manage it every time?
- Stuck? Press Hint to see a good move.
