1. The Piggy Bank saves extra diamonds while you play.
    It fills up when you spend diamonds or upgrade your machines. For every 1 diamond you spend, the Piggy Bank gets 10 bonus diamonds. Machine evolutions also give bonus diamonds.
  2. Diamonds you earn directly in the game do not go into the Piggy Bank.
  3. The Piggy Bank has different sizes. The smallest holds 200 diamonds, and VIP players have bigger ones.
    You can open the Piggy Bank only when it is full. You will not get the diamonds automatically — you must break it to collect them.
  4. When the Piggy Bank starts filling, a 72-hour timer appears. If you don’t open it before the timer ends, the saved diamonds are lost. A full Piggy Bank also resets after 120 hours.
