Have you ever played tic-tac-toe? If so, you’ll find that Four Square offers a more challenging twist. The objective is to form a perfect square using four blocks of your color. Each completed square earns you points—be careful, though, because your opponent is aiming for the same goal. Strategically place your blocks to both block your opponent’s progress and complete your own squares simultaneously. Think quickly, act even faster!
