Dinero is an in-game currency that can be used to purchase energy, continues, boosts, and venue upgrades. Dinero can be purchased through the bank or earned on select levels in the game. Dinero cannot be purchased using coins. You must either earn or purchase Dinero directly from the in-game store.
If you get three stars on a level where a VIP is first introduced (10, 20, 30 etc.), then you will receive free Dinero.
You may also earn Dinero by watching video ads. Just tap on the Dinero symbol on the top of your screen, scroll to the right, and tap "Free Dinero".
