Unroll Me - Unblock the slots is a free puzzle app game that's actually kind of fun. As soon as you turn the game on, the white ball will start rolling - slowly. You must quickly shuffle the tiles around to create a path to get it to the red square. See the silver squares? They're fixed in place.
There are 20 free levels and I must admit, they're fun. I solved the first 18.. Unroll Me is a great combination of arcade and puzzle.
