Play the game as you normally would and fill up the piggy bank with precious Gold. Feel free to break the Piggy Bank and withdraw the Gold at any time – but remember that the fuller your Piggy Bank gets, the better the deal becomes.

After each withdrawal, your Piggy Bank advances to the next tier, offering you great deals on Gold. The total amount of tiers is 5. After breaking the 5th tier, you will be able to re-fill tier 5 again.
