• Piggy Bank is a recurring purchase option which users collect gold in piggy bank after every winning level.
  • When it is half-full (300 golds), it is available for purchase.
  • But it would be much better to purchase when it is full since it has a fixed price.
  • If you purchase a piggy bank, collected golds will be yours and the piggy bank will start to collect gold from zero.
  • When it is full again, you can re-purchase.
  • Piggy Bank has an advantageous price over other shop items.
  • Since it is an available purchase with only “real money”, it is not obligated, but a choice for purchasers.
