Square Biz is an entertaining way to match wits with a friend or the computer. The object of the game is to score more points than your opponent by capturing four corners of any 2×2, 3×3, 4×4, 5×5, 6×6, or 7×7 square. The grey square is a shared and can be used by both players as one of the four corners.

You must choose the best combination of defensive and offensive moves to capture the four corners of the most 2×2, 3×3, 4×4, 5×5, 6×6, or 7×7 squares. Use the best strategy to capture the four corners of any square or to stop your opponent from capturing the four corners of any square. The shared square starts at a different location at the beginning of each game potentially affecting your strategy and making each game different from the last.
