When you watch Ads in the game, you will have the opportunity to play Spin to Win where you can win more awesome rewards!
Tap the Merchant to watch Ads.
After watching an Ad, you can now spin the wheel, then collect your reward.
Reach the bonus goal by watching the required number of Ads before the timer runs out to win a Bonus Chest. When you've reached your limit, you must wait for the cooldown timer to reset before spinning again.
