Tic Tac Toe is a classic 2-player strategy game played on a 3x3 grid. Each player takes turns marking a cell with either "X" or "O" to form a straight line—horizontally, vertically, or diagonally. The player who completes a line first wins the game. If all cells are filled without a winning line, the game ends in a draw. This simple yet engaging game helps improve logical thinking and strategic planning.
