Bubble Sort by PAandW Apps is a very simple game. Bubbles fall from the top of the screen. These bubbles are red, green, blue, purple, orange, or yellow. All you have to do is drag each bubble to the same colored circle. If a bubble reaches the bottom or you sort one into the wrong place, you lose. Simple as that.
