Square your brain power with two exercises designed to push you to the limit. Challenge your friends and see who is as sharp as a square's edge. In Mirror Game mode, exercise your processing power by rearranging a set of squares to match the given pattern. In Memory Game mode, exercise your short-term memory by remembering a pattern of squares and then reproducing that pattern. Each mode has at least three levels of difficulty.

One plays Square Brain by rearranging squares of different colors until the player is satisfied with their arrangement. The player submits their arrangement by pressing the submit button, and the game determines whether they have met the winning condition and won the round.
