Mutations in Kick a Lucky Block can make a huge difference in how fast you earn money. When you kick a lucky block, there's a random chance it opens up to reveal a mutated brainrot instead of a regular one. These mutated versions look different and earn more cash, so getting one is always a good thing.
All Mutations in Kick a Lucky Block
Right now, there are five mutations in the game. Each one applies a multiplier to your brainrot's earning rate and sale value. Here's a full breakdown:
| Mutation | Image | Multiplier |
|---|---|---|
| Golden | ![]() | 1.5x |
| Diamond | ![]() | 2x |
| Plasma | ![]() | 4x |
| Molten | TBA | 6x |
| Radioactive | TBA | 8x |
The multiplier works on both how much your brainrot earns per second and how much you get when you sell it. The devs haven't shared exact drop rates, so you can't know exactly how rare each mutation is. But from what players have seen, Gold and Diamond show up fairly often while Molten and Radioactive are much harder to land.
Note: More mutations are expected to be added in future updates, so keep checking back.
How to Get Mutations in Kick a Lucky Block
Every time you kick a lucky block, the game runs a hidden luck roll. If it hits, you get a mutated brainrot. If it doesn't, you just get a regular one.

The exact odds are not shown anywhere in the game, so it's purely luck-based. However, there are some things that you can do to increase your chances:
1. Global Luck Events
These are server-wide events that pop up randomly and last up to five minutes. During a Global Luck event, everyone on the server gets a luck boost. The boost can be 2x, 4x, or even 8x, which seriously raises your chances of getting a mutation. When you see one of these events active, kick as many lucky blocks as you can.
2. Land a Perfect Kick
Timing your kick perfectly gives you a temporary luck boost for that specific block. It's not a huge boost, but it's completely free and adds up over time. If you're consistent with excellent kicks, you're giving yourself better odds on every single block you open.

3. Buy the Mutation Luck Gamepass
If you want a permanent upgrade, the Mutation Luck Gamepass in the Store is worth looking at. It costs 349 Robux and permanently doubles your mutation luck. It stacks with event boosts and perfect kicks too, so during a Global Luck event, you're already working with a much higher base chance.

4. Upgrade Your Kick Power
Higher Kick Power quietly feeds into your overall luck calculation. It also lets you open blocks faster, which means more chances at mutations overall. Keep on buying new weights in the Weight Shop, and lift them! It will add your kick power gradually over time.

5. Stack Everything Together
The best possible setup is a Perfect Kick during a Global Luck event while the Mutation Luck Gamepass is active. All three stack together, giving you the highest practical odds of landing a high-tier mutation like Molten or Radioactive. Save your focus for these moments when everything lines up.
