Play the classic Tic-Tac-Toe game (XOX) for free online with two players.

The game is played on a grid that's 3 squares by 3 squares.
The first player to get 3 of her marks in a row (up, down, across, or diagonally) is the winner.
When all 9 squares are full, the game is over. If no player has 3 marks in a row, the game ends in a tie.
