The Piggy Bank is a feature that will offer you a number of gold bars and magic answers.
You will be able to access your Piggy Bank's progress through its icon on the home screen. Keep in mind that the more crowns you earn, the more items you can withdraw. For this reason, we recommend that you wait until it is full before claiming your prize.
To get the Piggy Bank's prize, you will have to pay a fixed price in real money.
You can buy it whenever you want, but remember that the prize will increase as you compute crowns; the more crowns you compute, the bigger the prize will be. Therefore, the more convenient it is to get it.
