The idea of the game is that you are given a blank area with a certain number of red balls bouncing around. In the empty space you can push down, which starts inflating a “smiley face” ball. If the red balls hit it the ball will pop, unless you have let go. The longer you hold down on the ball the larger it will inflate. The goal from here is to take up as much of the screen as possible, separating the red balls from each other into their own smiley prison. The balls rolls around freely, can change position, and even let more of the red balls go from their previous capture zone.
