The quickest game there is – now with bigger boards
Players take turns placing X and O. Get three in a row – across, down or diagonally – and you win. On the classic 3×3 board, two good players always draw, so try the hard level: the computer plays perfectly and can’t be beaten, only held to a draw.
Want more? On 4×4 and 5×5 you need four in a row, which gives much more room for traps and tactics. The starting player alternates every game and the score is kept.
How to use
- Choose the board size and whether you play the computer or a friend.
- Tap a square to place your mark. You are X against the computer.
- Line up three (on 3×3) or four (on 4×4 and 5×5) to win.
- Tap the board or New game for the next round – the starter alternates.
Ideas for using it
- Young children. easy level on 3×3 – they’ll win often and learn to spot lines.
- Challenge. can you hold the hard level to a draw every time?
- Bigger boards. 5×5 against a friend takes longer and rewards planning.
- Brain break. a quick round between lessons on the classroom screen.
