Complete rip off. Constantly drains coin to force a purchase and then will drain that as well. Seriously. Doesn't matter how low you spend, it'll just drain. Doesn't actually give awards that are promised. Takes up to a week if it says prizes will be awarded within 48 hours, and that's if it ever shows up. If you connect with Facebook, you will lose EVERYTHING as soon as your app crashes. Complete waste of time.
