How do I get items to upgrade my Vault?

Midas' Vault of Riches can continue to improve and give you great rewards as long as you keep leveling it up. Some of the items needed can be found in the machine itself, but most of them come from Merge Families in the Garden. The higher the Vault of Riches level, the harder to find the items. If you're ever truly stuck and don't know how to find an item, tap on the recipe card - it will give you info on where to find it.
