The Piggy Bank is a personal savings bank that allows you to save credits with every stake, spin and extra spin. These credits can be withdrawn later by breaking the bank. When you break it, the bank will reset with some credits already stored in it.
Reach level 4 to start saving credits!
To access your Piggy Bank click on the piggy icon.
The more you spin the larger your piggy will get. The amount you've collected can be found just below the piggy.
