"Tic Tac Toe" Game

In Tic Tac Toe, you have an X and your opponent has an O. On your turn, click anywhere on the grid to place an X in that square. Your goal is to get three crosses in a row before your opponent does. Test your skills by completing four attempts in a row on the 5x5 grid for an extra challenge. If it's still too easy, upgrade to a higher level by switching to the challenging mode. You can play against the computer or with a friend on the same computer.

Match 3 in a row to win. Match vertically, horizontally or diagonally.
