How to play Tic Tac Toe
Players take turns placing X and O in empty squares. The first player to connect the selected number of identical marks in one straight line wins. Lines can run horizontally, vertically or diagonally. If the board fills without a winner, the game is a draw.
Visual example of a winning line
On a 3 × 3 board, connect 3 matching symbols in a row. The highlighted pink X symbols below show a winning line.
Highlighted winning rule: Connect 3 in a row. The yellow-bordered X symbols form a complete winning line. The blue O shows an opponent's move.
Choose a board and winning length
Classic 3 × 3 Tic Tac Toe uses three in a row. On a 4 × 4 board, you may choose three or four in a row. Larger 5 × 5 and 6 × 6 boards let you adjust the challenge. The example changes whenever you change the game settings.
Tips to win
- Block your opponent before they complete the required line.
- Try to create two possible winning lines at once.
- Watch diagonals as well as rows and columns.
- Use Easy mode to practise before trying Medium or Hard.
