It really depends on what your taste in games are.

many good iphone games

At first these sound super dumb and like WTF? But I can't leave the apps:
Hay day
Bakery story
Temple run
Fruit ninja
Flows diner dash
Sweet talk
Flow (free)
Bag it
Ruby blast
Mega run
Draw some

Like try them out and see if you like them (at first bakery story and hay day are kinda boring but as you level up you can't leave the game lol. As some people watch me they're like that's it? That's all you do? YES BECAUSE IT'S FUN lol)
