Tic Tac Toe is a classic two player game where one player is "X" and the other player is "O". The board is a 3x3 grid containing nine playable spaces. The players alternate turns placing their "X" or "O" in any open space on the board. Winning the game is achieved by having three of the players "X"s or "O"s in a horizontal, vertical, or diagonal line. The two players alternate who is "X" and "O" each game and "X" always makes the first move.
