It was one of my favorite games back when I was a broke student. I eventually deleted the app because there were no free puzzles for the week. (maybe you can do a watch-an-ad for a random free puzzle?) Will probably buy a pack or ten when I'm done redoing the free levels!

Fun and challenging puzzles. Wish there were more offered without having to pay.
