The multiplier wheel is a special promotion that only comes up when you make a purchase. This wheel offers you the opportunity to win up to ten times your purchased coins for the same price as your initial purchase.
The initial purchase and the multiplier spin are two separate purchases. The initial purchase will give you a select amount of coins and the multiplier wheel purchase will determine the multiplier of the coins you made in the initial purchase. You can view this by looking at the wheel itself. You will see Payment x Multiplier = Payout.
Both the initial purchase and the multiplier are independent purchases yet they work in tandem to create the total payout.
