Your higher priority in the game should be to unlock zones that contain craft stations. How to find these? It’s relatively easy, they have a building looking like a laboratory or a workshop.

Want Ads change according to your current level in the game.
As you progress and level up, the Ads will require newer items to be completed, and these will be available only from the new craft stations located in new zones of the town.

You can also Unlock Areas by pressing on the unlock Icon On Top of the zone

Craft Items

Tap on the crafting station to craft items. You can only craft items if you have the required materials. You can get the missing items by spending bills.
