Connect two of the same icons (pairs) with your mouse to remove them from the board. Pairs can only be connected if they have at least one open side and if they are a maximum of two (90 degrees) turns away from each other. You can also connect two of the same icons if they are situated next to each other.
Connect and remove all icons from the board before your time runs out to finish the level. Complete all 10 levels to finish the game!
