No — you can’t use Sweepstakes Coins (SC) and Gold Coins (GC) in the same game round. Each game session requires you to select one currency before you start playing.
If you choose Gold Coins: You’ll play purely for fun, with no prizes attached.
If you choose Sweepstakes Coins: You’ll play for the chance to win SC, which can later be redeemed for real prizes once playthrough requirements are met.
This separation ensures clarity: every spin, hand, or scratch is played with one currency only, so you always know what you’re competing for.
