i have a iphone and most games on iTunes are also on droid store
Dont be a cheap fag and just spend some cash,hard to get good games for free
I suggest:
Angry birds (Duh)
iFunny (It sucks but still a source of very mild humor)
Minecraft PC
Baldurs gate
Dont get candy crush saga or crime city ect.
Throw some emulators on your phone and pick up some GBA games. Oh and I found an emulator to run Final Fantasy 7, so if you're into that you can google around for it. Be warned: Takes up most of your phone storage and battery life.
