Gold Coins and Smile Coins are two different currencies that you can play our games in. You can always see on the toggle bar if you are playing with Gold Coins or Smile Coins. All Smile Coins that you receive will go into your Unplayed Smile Coins balance and once you use them to place sweepstakes one time, any remaining Smile Coins will be transferred to your Redeemable Smile Coins balance. The Redeemable Smile Coins balance is the coins that you can choose to redeem into cash, Gold Coins on the other hand can not be redeemed into cash.
