A piggy bank is an opportunity to reasonably purchase coins.

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 at an affordable price.

By collecting the amount of coins presented, you can buy all the coins immediately, or you can keep collecting them for an affordable price. The amount of bonus coins earned is proportional to the number of regular coins earned by breaking the level.

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 :)
