XO Game

A well-known logical game called XO. It is known also as Tic Tac Toe in the same places. But the goal is the same. You will play on a grid that's 3 squares by 3 squares. You are X, and your friend (or the computer in this case) is O. 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. So, try to make three marks first and win the game. But sometimes the game will finish without a winner. Think before ever
