How to Play
Tic Tac Toe is played on a 3x3 grid. Players take turns placing their mark—X or O—in an empty cell. The first player to align three marks horizontally, vertically, or diagonally wins. If the grid fills with no winner, the game is a draw.
Against a perfect opponent, the game always ends in a draw if both sides play optimally. The real challenge is punishing mistakes and finding forced wins.
