Secret Squares
Find four dots that make a square, before your rival does.
About the Game
An 8×8 grid of dots sits between two players. The rule: find four dots that form a true square, including squares tilted at an angle, not just ones lined up with the grid, before your opponent does. Played live, best of three rounds.
