Yunus Ayyildiz's Hocus has been downloaded over 1,000,000 times. Normally, it's $.99, so he's made himself a small fortune.  Good for him. (If only other great puzzle apps would have such success.)

The objective is to roll the red cube around the impossible shape to get to the exit

There are 89 levels and I've done 60 in the past 2 days. They go pretty fast but I've gotten stuck in endless loops. 
Also, this puzzle app game allows you to create your own shapes for others to solve.

Update 8/14/16: I finished all 89 levels and even created 2 of my own levels. 

Yunus's other game Voi coincidentally, reviewed this same week.
