All Sweep Coins must be used at least once (3x) to be eligible for redemption. For example, if you have 50 Sweep Coins, you will need to use a total of 150 Sweep Coins before they can be redeemed for a prize.
Sweep Coins obtained through giveaways have a 10x rollover/playthrough requirement. This applies specifically to Sweep Coins earned through promo codes, daily boosts, or promotional giveaways.
