Knots and Crosses

Knots and Crosses, also known as Tic-Tac-Toe, is a simple two-player game played on a 3x3 grid. Players take turns marking a square with either an "X" or an "O." The objective is to form a straight line of three of your marks—horizontally, vertically, or diagonally—before your opponent does. The game ends when one player wins or all squares are filled without a winner, resulting in a tie. It serves as a basic introduction to strategic thinking and is often used to engage children in learning concepts of competition and planning.
