Coins are earned during play, can be purchased in the store, and awarded through bonuses.
Coins that appear from flipped cards can be collected by tapping or swiping over them. If left alone, coins automatically move to the Treasure Chest.
Bonus: Every four hours, tapping the bonus button will award coins. Other coin bonuses will sometimes appear in the game.
Check for Grants: Tap this button if the Slingo® Shuffle support team has sent you coins to replace coins lost to in-game errors or missing purchases.
Purchase coins in the store: Coins are available in the Slingo® Shuffle in-app store. These coin bundles can be purchased using real world currency and iTunes/Amazon/Google play credits.
