Like item paths, generators themselves can also evolve! This happens slowly as you progress through the game.

To upgrade a generator, you need to find items of the GENERATOR PATH. You can find these items in reward chests that you receive from LEVELLING UP and FINISHING A STORY DAY. Merge these items together to make new and upgraded generators.

Upgrading a generator makes it more powerful, increasing its chances of creating better items for you, which in turn makes it faster to serve your customers!

To find out more about a generator's item path, tap on the item or generator you want to learn more about. Then tap on the blue "i" button in the INFO PANEL. The info panel is at the bottom of the screen, in between the Storage and Back to Cafe buttons.
