Game is fun but when you run out of coins you have to watch ads which is no big deal, however or only get 1 coin per ad. When you start getting to higher levels each try is about 7+coins. So you are pretty much forced to buy coins or else you cannot continue. Also it starts you back at level 1 when you run out. Very frustrating. Otherwise game is extremely addicting.
