How do I make purchases?

There are multiple ways to buy in-game currency:

Tapping the + beside your Coins or Diamonds balance. Your VIP bonus is applied here.
Buying Coins or Diamonds packs from the Shop.
Buying a WCASE, which includes random amount of Coins and Diamonds within a range, and a random item.

If you find yourself low on Coins while spinning, the game will give you the option to buy more!
