There use to be rewards after 20 stars making it worth making purchases to play longer. Those rewards have been taken away as well as 10 extra lives. There used to be a build up of 20 lives, now you can only have 10 lives to ask for lives from other players. But, You still have to wait four hours to ask for 5 lives. Yes, this is a pay to play game, I don't understand why the developers keep insisting that it isn't.
