I purchased a booster and have NOT been able to use the "One hour power". I have lost days of usage. Today it says I have 5 days left and still can not access this booster. Also some of your games only pay 80% of you bet when you get free spins other games pay 3 to 5 times your bet. Your app has alot of flaws and these flaws are always in your favor, not the players.
