Roll Cases for Brainrots Mutation Tier List
Confirmed Galaxy, Magma, and Lava versus unconfirmed stickers — September 2026 working ranks.
Mutations are the multiplier layer on Roll Cases for Brainrots. A mid Brainrot with the right coat can out-earn a naked rare. This list is a community working rank for September 2026. Confirmed names come from official promo art and from pass labels: 8x Mutation Luck, 4x Mutation Luck, 2x Mutation Luck, plus 2x Luck and VIP’s 2x Luck. Ritual luck is a separate pass (2x Ritual Luck), so rituals exist even without a public recipe sheet.
We do not import Yin-Yang, Radioactive, or other sticker books from Steal a Brainrot unless a patch on place 97665661589897 says they dropped here. Unconfirmed names stay in a holding pen, not in S. The grind walkthrough is how to get mutations. The roster view is Brainrot mutations. Sibling ranks: cases, Brainrots, gamepasses. Hub: Tier List Hub.

| Unconfirmed | Yin-Yang, Radioactive, others | Other Brainrot games, not this place’s art | Do not chase |
Promo $/s numbers describe crate fantasy income, not a lab measurement of each mutation. Still, the art set is consistent: Lava is the ceiling, Galaxy is the stylish mid-high, Magma is the fire stepping stone.
S — Lava mutation
Lava is the coat that matches the far crate and the 0.01% cerberus-style dog. If a unit picks up Lava, it is a plot carry until something with a higher ticking $/s arrives. Park it in slot one. Plot setup wants mutation units on visible, safe pads so you notice them and so you do not fumble them while a wave is incoming.
You reach Lava mutations by reaching Lava (and maybe Magma) crates, then stacking mutation luck. Jump first. How to jump farther is the real gate. 8x Mutation Luck is the spender hammer after that gate; 4x and 2x are the cheaper rungs. We do not list Robux prices.
A — Galaxy and Magma
Galaxy is the pink look. It is the mutation you should actually expect to see before Lava, because the pink crate is the mid-far chase on the case tier list. Keep Galaxy hosts. A Galaxy mid unit often beats an unmutated Mythic drop.
Magma is fire without the full lava ceiling. Promo Magma crates sit at $999M/s, so a Magma coat on a decent host is how early plots look rich. Do not sell a Magma host to make room for a slightly prettier common. Sell the common.
B — Generic luck and ritual luck
Generic luck is not a coat. It is the chance layer: 2x Luck, VIP (2x Luck plus 1.5x Cash plus a tag), and the mutation luck family. Rank luck as B if your bottleneck is still jump distance. Rank it as S for your wallet only after Auto Train or 2x Strength has your arc landing the crates you care about. The gamepass tier list and gamepass value tool split those goals.
Ritual luck is B because the system is confirmed by a pass name and the recipes are not. Keep a couple of possible ritual pieces as the Brainrot list says. Do not freeze your plot waiting for a board that has not been posted.
How to stack without wrecking the plot
- Train legs (Getting Started, progression tool).
- Collect the crate you can actually land (how to open cases).
- Open, then compare $/s with your worst slot (best Brainrots).
- Keep hosts; sell filler.
- Add mutation luck only when you are opening the right lids, not Mythic spam.
- Collect cash. Auto Collect helps. Tsunami still wants speed and an escape plan.
- Rebirth after the mutated keepers are parked (how to rebirth).
Faster Case Spin does not raise mutation chance; it only shortens the animation. 3x Cases is off sale. Codes, if RNG Collective drops any, go on Codes. Optional script talk is on Scripts. Official links: Links. Patch movement: September 2026 updates.
Until a patch names a new mutation on this place, do not import another game’s sticker book.
Frequently Asked Questions
Quick answers for Roll Cases for Brainrots.
Which mutations are confirmed?
Galaxy, Magma, and Lava from official art, plus generic luck from 2x Luck, VIP, and the Mutation Luck passes. Rituals are confirmed as a system by 2x Ritual Luck.
Are Yin-Yang or Radioactive in this game?
Unconfirmed for Roll Cases for Brainrots. They belong to other Brainrot titles unless a patch on this place says otherwise. Do not hoard filler for them.
Does 8x Mutation Luck replace jump training?
No. Luck rolls the crate you already collected. Lava coats still need lava (or late fire) lids. Train first; see how to jump farther.
Should I mutate commons?
Mutate hosts you would keep anyway. A Lava coat on junk is still a slot. Rank the final $/s with Place Best in mind.
What is the difference between mutation luck and ritual luck?
Mutation luck targets coats such as Galaxy, Magma, and Lava. Ritual luck is a separate pass, so rituals are a different loop. Recipes are not public yet.
Where do I read the grind steps?
Use how to get mutations for the loop and Brainrot mutations for how coats sit on the roster.
