The Piggy Bank is unlocked after you complete Level 15. It is an opportunity to buy Coins at a good price.

While the piggy bank is in progress, you will receive bonus coins for each level you clear, independent of the regular rewards. These coins are kept in a piggy bank, and if you collect more than a certain amount of coins, you can buy them with a good deal!

Bonus coins do not affect general rewards. In other words, if you pass the level, you will get the same amount of coins as usual with or without a piggy bank.

You can't disable a piggy bank, but you can leave it unused. You don't have to use it!

We hope you keep enjoying our games :)
