The main difference between sweepstakes and traditional casino apps is the use of virtual currency that has no actual monetary value. In regular online casinos, you must deposit your own money to play casino games; this is not the case with sweepstakes casinos. In sweeps apps, you will find two types of virtual currency: Gold Coins and Sweepstakes Coins. The main difference is that Sweepstakes Coins can be redeemed for prizes.
