In Piggy Bank you need to drop coins into your Piggy Bank to fill it up. In each level there are adjustable ramps you need to move their position to help your coins drop into the Piggy Bank. Once you figure out a working plan, release the flood gates and fill your bank!
Using your mouse or finger you can adjust the ramps to change the direction of your dropping coins. Where you tap or click on the blue button controls where your coin drops as well.
