How to play Tic-Tac-Toe

1. Take turns marking empty cells — ✖ goes first.
2. Classic 3×3: first to get 3 in a row (across, down, or diagonally) wins.
3. Bigger boards change the goal: 5×5 needs 4 in a row, 7×7 needs 5 in a row.
4. Tap any empty cell on your turn; the last move is ringed so you can see what just happened.
5. If the board fills with no line, the game is a draw.

Tic-Tac-Toe strategy

The basics that turn knowing the rules into winning games — what to do first, what to keep, what to avoid.

• On the 3×3, take the centre first; if the centre is taken, take a corner. Edges are the weakest squares.
• Look for a FORK — one move that makes two lines of two at once — and block your opponent's fork before it exists.
• On the 5×5 and 7×7 boards (four in a row to win) an open-ended three in a row is already unstoppable; make one, or stop one.
• Perfect play on 3×3 is always a draw, so the win comes from the other player's mistake — play the safe move and wait for it.
