I wonder if it’s possible to sell two different versions of an app at the same time in Apples appstore?
For example: I have a game with 10 levels. I build a version where all 10 levels can be played and I put it in the store for 2.99$ in categories Game-Arcade / Game-Puzzle.
Now I create a different version where you can play 2 levels of the 10 for free and you can unlock the rest of the levels via In-App Purchase for 2.99$. This version I put for free in categories Game-Kids / Game-Adventure.
Is this possible and not violating any stuff at Apple? I couldn’t find anything, so I think it is possible… but I want to be on the safe side here because no one else seems to do it… or maybe I just haven’t looked long enough to find apps like this. 
Any hint welcome!
Have a nice weekend!
