- You and your opponent take turns tapping an empty square to place your mark.
- The standard board is 5×5: get four of your marks in a row — across, down or diagonally — to win the round.
- Want the classic game? Tap the board chip and pick 3×3 (three in a row), or go bigger, up to 8×8.
- If the board fills up with no line, the round is a draw.
- The first move swaps each round, so nobody always goes first.
Tips
- Block a line of three before it becomes four.
- Easy, Medium and Hard change how well the computer plays.
- Playing the computer or a friend on the same device? Undo takes back your last move.
