Supercharge is a brand-new feature that we are trying out in the game. If you have Supercharge in the game, you can activate it by clicking on a producer and toggling the Supercharge switch on.

The way it works is that once activated, you will see a different "Energy" icon pulsing on the Producers it can be used on. Once you tap such a Producer, you spend 2 energy instead of 1, and you have better chances at getting a higher level item than before.

For players that have this feature available, you can always turn it ON/OFF from the toggle button you can see in the info panel when you click on a Producer.

We are trying to see if this change makes the game more enjoyable for players, which is why not all players have it yet.
