I've experimented with more than 3 bubble shooter with different implementations such as Snap, Match and Fall, endless row generation, etc. after all I had slow and had no great performance in iPod Touch 4, however iPod touch 4 runs great with this game:

I'm kinda disappointed how to accomplish the bubble shooter with more CPU friendly while control of quanity of bubbles and no collisions.
Do you have better ideas?
