Get three of your marks in a row — horizontally, vertically, or diagonally — before your opponent does.

- Tap/click an empty square. X always starts.
- Play as X against the computer, or share the board with a friend.
- Tab to the board, use arrow keys, then Enter or Space to place your mark.
- Three matching marks in a line win. A full board with no line is a draw.
