What are some cool iphone games (that don't use internet)?

I don't really like first person shooters, but not all those stupid "college campus" or "hello kitty cafe" or "temple run" stuff. Slender was pretty cool, but kindof boring after a while. I have a half hour bus ride to school every moring plus waiting at the bus stop so any cool apps would be appreciated.

I like the game flow

I don't think you'll need internet with Mino Monsters. You can also check Zombie Tsunami, where's my Water, Stupid3 and Pocket Climb.
