Quick answer
The current best mutation is Radioactive because public mutation guides report an 8x multiplier. A full brainrot tier list is still pending because exact income, sale value, and drop-rate data need in-game proof.
Best mutation tiers
This tier list ranks mutations by reported multiplier, relative rarity, and practical route value. A higher multiplier is strongest when it lands on a valuable base brainrot, so base reward quality still matters.
Molten
6x reported multiplier
The strongest realistic chase roll below Radioactive and a major late-game upgrade.
RareStill rare enough that weak blocks should not consume your best luck windows.
Plasma
4x reported multiplier
High enough to matter on most useful brainrots and easier to plan around than the rarest roll.
UncommonA Plasma roll on a weak base brainrot may lose to a lower mutation on a stronger base unit.
Diamond
2x reported multiplier
A good early and mid-game value boost because it doubles the base brainrot result.
CommonUseful, but not a reason to stop upgrading kick power or route quality.
Gold
1.5x reported multiplier
A starter-value mutation that is better than a base roll but sits at the bottom of the mutation table.
Most commonWorth keeping on stronger early rewards, but not worth building the whole route around.
How to use the tier list
Better base blocks make every mutation more valuable, so early routing beats rare-roll chasing.
Use active luck windows when you can reach higher-value rewards instead of repeating weak starts.
Track the brainrot, mutation, income, sale value, and server state before updating rankings.
This is a mutation-first tier list. It does not claim a verified best brainrot, trading value, or exact drop rate until those numbers are confirmed from the live Roblox experience.
What is still unverified
| Topic | Status | Proof needed before ranking |
|---|---|---|
| Individual brainrot tier list | Pending in-game values | Brainrot name, base income, sale value, source block or zone, mutation state, and screenshot or video timestamp. |
| Trading or value list | Not confirmed | Visible trading system, repeatable market values, and current player demand signals from the live game. |
| Exact mutation drop rates | Unknown | Official developer table or a large recorded sample from current servers. |
Best target order
If you are already reaching worthwhile blocks, treat the rankings as a chase order rather than a guarantee: Radioactive is the best ceiling, Molten and Plasma are strong keeper rolls, and Diamond or Gold are early upgrades while you build toward better routes.
A rare mutation is most valuable when the base brainrot already has useful income or sale value. Do not judge the roll by multiplier alone.
If a page lists exact trade prices without showing the live trading system or screenshots, keep that data out of the tier list.
Avoid Kick a Lucky Block script, auto farm, perfect kick, or executor pages. They are not redeem codes, and they can put your Roblox account or device at risk.

FAQ
What is the best Kick a Lucky Block mutation?
Radioactive is the top mutation in this tier list because current public guides report it as an 8x multiplier, the highest known mutation multiplier.
Is this a full brainrot tier list?
No. This page ranks mutation value because those multipliers have public source support. Individual brainrot rankings stay pending until income and sale values are verified in-game.
Why are Plasma and Molten both A Tier?
Molten has the higher reported multiplier at 6x, while Plasma is still a strong 4x roll and should be easier to encounter than the rarest mutations.
Should beginners chase S Tier mutations first?
No. Beginners should build kick power and reach better blocks first. A rare mutation matters more when the base brainrot is already valuable.
Are exact mutation drop rates known?
No official drop-rate table was confirmed during this check, so this tier list uses reported multipliers and marks exact rates as unverified.
