Pretty awesome for a slots game I can't win real money on. It has kept me interested in spite of that fact. However about level 25 the goals become much harder and they make it almost impossible for you to continue without paying for more coins. (Edit added 12/1: I did not realize until yesterday they have an option to watch an add for a million coins! -Making it much more possible to keep you playing! Now my only complaint is I can't get anything accomplished because I can't quit playing!)
