Choose your grid format: Classic 3x3 (3-in-a-row) or Expanded 5x5 (4-in-a-row).
Players take turns placing their signature tokens (Circle vs Cross) onto empty squares.
The first player to form an unbroken straight line (row, column, or diagonal) wins.
If the grid fills completely with no line achieved, the match concludes in a draw.
💡Tactical Strategy Tips
In 3x3, securing the central square or opposite corners grants optimal line control.
In 5x5, build open-ended threes (unblocked on both sides) for an unstoppable finish.
