How to play
The goal
Players take turns placing their token (X or O) on the board. The first to line up their tokens in a row — across, down or diagonally — wins the round. A full board with no line is a draw.
- 3 × 3 classic: get 3 in a row.
- 4 × 4: get 4 in a row.
- 5 × 5: get 4 in a row.
Game modes
- vs Computer — four levels from Easy to Unbeatable. On 3 × 3, Unbeatable never loses: a draw is a great result!
- Pass & Play — two people share one phone.
- Online — host a game to get a 6-letter code, send it to a friend, and they join from their phone. Chat with 💬 during the game.
Tips
- Take the centre early on 3 × 3 — it is part of four winning lines.
- Create a fork: two threats at once can’t both be blocked.
- Always check whether your opponent is one move from winning.
