There are three Mutations in Roller for Brainrots: Golden, Diamond, and Rainbow. Mutated brainrots can spawn naturally in all areas of the map. Rainbow is the best mutation in the game right now (6x multiplier). Roller for Brainrots also has multiple Traits like Lava, Candy, Galaxy, Fat Bro, and more. Traits don’t change the appearance of the brainrot, but they do increase the earning rate and sale value. You can only get brainrots with Traits during specific server events. Food is currently the best trait in the game (5.5x multiplier).
If you want to make lots and lots of cash so you can upgrade your rollers and reach high-rarity areas, you need to find and collect brainrots with Mutations and Traits. These brainrots earn more than their base variants, making them extremely valuable. But not all mutations and traits are worth keeping. In this complete Roller for Brainrots mutations and traits guide, you’ll learn everything about these two mechanics.
All Roller for Brainrots Mutations - Multipliers & How to Get
| Mutation | Multiplier & How to Spot | How to Get |

| Diamond | Increases the brainrot’s earning rate and sale value by 1.5x. Diamond brainrots will have a completely cyan appearance, and the text ‘Diamond’ also appears above their heads. | Brainrots have a low chance of spawning with the Diamond mutation in all areas of the map. |
| Rainbow | Increases the brainrot’s earning rate and sale value by 6x. Rainbow brainrots have a plain appearance, and the text ‘Rainbow’ appears above their heads.

Brainrots can only spawn with one mutation. There’s no way to get a brainrot with multiple mutations. Because Rainbow applies the highest multiplier to the brainrot, it is currently the best mutation in Roller for Brainrots.
