Tic Tac Toe

You are X’s and your opponent is O’s. On your turn, click anywhere on the grid to place an X in that square. Your goal is to get three in a row before your opponent does. Try your skills getting four in a row on the 5x5 grid for an extra challenge. If things are still too easy, take it up a notch by switching to hard mode! You can play against a computer, or with a friend on the same computer.
