Tic Tac Toe

How to play Tic Tac Toe

1. Choose an easy computer, an unbeatable one, or a friend playing on the same screen.
2. Take turns placing X and O. The first to get three in a row, across, down or diagonally, wins.
3. The first move swaps between X and O each game, and the score is kept until you change the opponent.
