This is one of those iPad apps where you “buy” the free version and then buy the full version out of guilt because you got so much use out of the free game and… it is only a dollar. I could explain the game but really all you need to do is look at the image and you already know how to play. You just match up the bubbles and pop them. I stole this image from LunchBoxReviews.com which provides reviews of a lot of iPad education apps.
