Tic-Tac-Toe

Three in a row wins. Quick, sharp, and surprisingly deep against a perfect AI. The ideal one-minute match.

How to play

1. Players take turns. You are X, your opponent is O.
2. On your turn, tap any empty cell to place your mark.
3. Get three of your marks in a row — horizontal, vertical, or diagonal — to win.
4. If all nine cells fill with no line, the game is a draw.

Tips & strategy

• Take the centre on your first move — it sits on more winning lines than any other cell.
• Look for a fork: one move that makes two winning threats at once can't be blocked.
• Against perfect play every game is a draw, so play for your opponent's mistakes — and never miss a block.
