The object is to maneuver the smiling, happy balls into the white holes by tilting the iDevice so that each ball rolls into a hole. Once trapped in the circular depression or hole, the ball remains there permanently. All balls roll and collide realistically, constrained by the edges of the screen. The first of the 33 levels are fairly easy, but soon players must face stationery black holes and rolling angry balls that swallow up happy balls, and losing any happy ball makes it impossible to complete the level, ending gameplay. Scoring is based on elapsed time to complete a level, and players must successfully complete a level before moving any higher.
