Tic Tac Toe (also known as Noughts and Crosses or XOXO) is a classic paper-and-pencil game for two players who take turns marking the spaces in a 3×3 grid with X or O. The player who succeeds in placing three of their marks in a horizontal, vertical, or diagonal row wins.
Player X always goes first. Click on any empty square on the 3x3 grid to place your mark. Alternate turns with your friend until one player gets three in a row or the board fills up resulting in a tie match.
