- Get three of your symbols (X or O) in a row (horizontally, vertically, or diagonally) on a 3x3 grid.

- Two players take turns.

- Player 1 uses X, Player 2 uses O.

- Players mark an empty square in each turn.

- The first player to align three of their symbols wins.

- If all squares are filled without any player aligning three symbols, the game is a draw.
