Number of ads in this game simply arent worth the hassle. Sure its a mini game and its some likeness of one advertised for young kids to play now. However, at the end of a level regardless if you want to continue or do "double coins" or extra pieces, you'll still have to deal with the ad when you choose no thanks anyways. Some say close and reopen. That doesn't even work everytime too, as it'll reset the progress and you'll be faced with redoing said level and the ad interface continues.
