In this guide, I have shared all the Build a Ring Farm Mutations, along with their multiplier values. This guide also covers how to trigger these mutations on the crops.
Build a Ring Farm Mutations and Multipliers
Mutations in Build a Ring Farm are special effects that can massively increase the value of your crops. When a plant receives a mutation, its appearance changes and its income multiplier increases depending on the mutation type.
Some mutations can only be obtained during limited-time events, while others can also be applied using sprays purchased from the Gear Shop. Below is the full mutation list along with their multipliers, appearances, and unlock methods.
Mutations in Build a Ring Farm cannot stack — a plant can only have one mutation at a time. And, you must be online during events for mutations to apply to the plants.
