Tic Tac Toe, or X-O, is a classic game of strategy.

You play the game on a 3×3 grid with three marks per player.

You will have to place three marks on the grid in order to win.

Each player starts with two tries.

If you are the first to place three marks in a row, you win.

If not, you lose.

If you lose the first two times, you will not be able to play.

Tic Tac Toe is a great game for two players, called "X" and "O", who take turns marking the spaces in a 3×3 grid.
