There are 13 gold stars up for grabs if you have the 3 level packs. The 14th comes when the 4th level update comes out. All the stars are pretty easy to get when you look on youtube. The radio star was bugging me for a while because the way to do it on the iphone is by pressing 2 keys at the same time. but on one of the other threads here someone informed us you auto tune to the big O in rovio ;-)
