How to play Tic-Tac-Toe Plus
Choose the classic 3×3 board or the big 9×9 board, where you need five in a row. Pick the computer level or a friend, and how many games the match lasts. Players take turns placing X and O; the first to complete a line wins the game, and the match goes to whoever wins most games.
Controls
- Click / tap a square, or use the arrow keys and Enter (keys 1–9 on 3×3).
- Pick the board, opponent and match length on the first screen.
Works with keyboard, mouse and touch screens.
Features
- 3×3 classic and 9×9 five-in-a-row boards
- Easy, Normal and Hard computer opponents (Hard never loses on 3×3)

Tips
- On 3×3, taking the centre first gives you the most winning lines.
- On 9×9, block any open three before it becomes an open four.
- Make two threats at once: your opponent can only block one.
