Tic-Tac-Toe is a simple, player-versus-computer or player-versus-player game that is played on a 3x3 grid. The objective of the game is to be the first player to get three X's or O's in a row, either horizontally, vertically, or diagonally. Players take turns placing their mark on an empty square until one player wins or the game ends in a tie if all the squares are filled. Although the game is easy to learn, it still requires strategic thinking and planning to outmaneuver your opponent and come out as the winner. Tic-Tac-Toe is a timeless classic that is enjoyed by people of all ages and continues to be a popular pastime today.
