Push It! is extremely popular at the App Store.  The object is to fill all the spots with balls. The sequence of sending the balls is all important.
The graphics are very good. However, I immediately thought about the game Zhed (see link below).
I was hoping for some new element. Orixio is basically the same, and later came out with Orixio with wormholes.
