What is the Piggy Bank and how does it work?

The Piggy Bank is a recurring source of a discounted bundle of Gems and Hero Coins, which can be purchased, via an in-app purchase, at any time. The Piggy Bank gradually fills up as players open up or skip loot chests in their chest slots, but the cost stays fixed, meaning the value of the Piggy Bank continually grows up to its maximum amount once the bank is full.

The Piggy Bank has a maximum capacity of 1700 Gems and 10 Hero Coins and once purchased, the contents will be reset to the starting amount.

HOW MUCH DOES EACH LOOT CHEST ADD TO MY PIGGY BANK

In general, the more rare the chest, the more Gems it adds to the Piggy Bank:

• Common: 50 Gems
• Rare: 150 Gems
• Epic/Giant: 300 Gems
• Legendary: 600 Gems 

A new Hero Coin is added with every 170 Gems added above the reset point of 850 Gems.
