This game is a scam!!!! For first time players do not use any boosts for the first three worlds and see how quickly you level up and get rewards. Everyone should report this app to google and the FTC FOR UNFAIR PRACTICES AND DECEPTION. You can't win witbout boosts and boosts cost money, thus you have to pay to win! This goes against their theory it is random. If their business was scrutinized and reported by more peole we might get somewhere. This app should constitute as gambling!!!!!
