Piggy Bank

You can get additional benefits from the spent energy by using the piggy bank, which becomes full when you spend energy on collecting resources.

To see how full the piggy bank is, tap the icon at the top of the screen, and the scale will show how close you are to reaching the goal. As soon as the piggy bank is filled all the way up, you will be able to take advantage of a special offer.

When the timer expires, the offer will disappear, and the piggy bank will have to be refilled.
Important! The piggy bank does not fill up in exchange for your own energy but in exchange for actions performed in the game. The more actions you perform, the faster the piggy bank will fill up.
