Mutations in Roblox’s Break a Lucky Block will significantly improve your Brainrot’s passive earnings. However, to apply mutations to your Brainrots, you will have to use the Mutation Machine. The Mutation Machine requires two units of the same Brainrot and some cash to work. Currently, there are six mutations that you can achieve from the machine. Keep in mind that you will require two Brainrots of the same type for the machine to work.

How the Mutation Machine Works
To start off, the Mutation Machine is located in the safe zone area. You can find it beside the Brainrot Trader’s Shop. Just walk over to the machine with your Brainrots to use it.
Here are all the steps to use the Mutation Machine:
- Equip the Brainrots and place them in the machine one by one.
- Press and hold ‘E’ on your keyboard to interact with the machine.
- Pick two Brainrots of the same type that you want to mutate.
- Select the Mutate option to start the mutation process.
- Wait for the mutation process to complete.
- Collect your mutated Brainrot and place them in your base.

Note: You can only mutate one Brainrot at a time.

- If you’re a beginner in the game, you can start by mutating common Brainrots and work your way up to the rarer ones.
- Keep collecting Brainrots and storing them in your inventory. This way, you can check which Brainrots you can mutate early on and which ones you will need for upcoming mutations.
- Always pick three Brainrots of the same unit so you can keep one in your base and place two in the machine.
- Pick up mutated Brainrots and store them in your base or inventory so you can use them later in the machine.
