If you want the fastest progress in Kick a Lucky Block, the biggest question is simple: which brainrot is actually worth keeping in your base? The answer depends on both rarity and mutation, since a lower-rarity brainrot can sometimes outperform a higher-rarity one if it has a strong multiplier.

Based on the current in-game index and player footage from the latest update cycle, the best brainrots are the ones with high base income and especially strong mutations like Rainbow, Electrified, and Shadow. Celestials are already excellent, but the top end goes much higher once you find the right mutation.

Best brainrots in Kick a Lucky Block tier list

Here’s a practical tier list built around base income, rarity, and how valuable the brainrot becomes with good mutations.

TierBrainrotsWhy they rank here
S+Abyssal brainrotsHighest base income seen in the current list
SEternal brainrotsVery strong income and top-tier for long-term grinding
A+Celestial brainrotsHuge upgrade over lower rarities, especially with mutations
AOG brainrotsExcellent income and often worth keeping for a while
BHacked, Divine, SecretStrong mid-to-late game options
CGodly, MythicGood early progression, but quickly replaced
DLegendary and belowFine for early game, but not your end goal

Best brainrots by rarity

If you are climbing normally, the best move is to focus on the highest rarity you can reasonably reach, then keep an eye out for a strong mutation.

S+ tier: Abyssal

These are the current top-end picks in the public index.

BrainrotBase income
Lucky Fella$5M/s
Coinator Baconator$6.5M/s

If you get one of these, it is usually a major power spike. Even without a mutation, they are among the most valuable brainrots in the game right now.

S tier: Eternal

Eternals are the next big step up.

BrainrotBase income
Ketupat Kepat$1.2M/s

This is a huge jump from Celestial and below. If you are still progressing through the late game, this is the kind of drop you want to keep.

A+ tier: Celestial

Celestials are where a lot of players hit their first real endgame wall.

BrainrotBase income
Dragonfrutina Dolphinita$475K/s
Guerriro Digitale$490K/s

In player footage, Celestials are already considered strong, but not always enough to beat the absolute best mutated pieces. Still, they are extremely useful and often worth equipping immediately.

A tier: OG

OG brainrots remain strong late-game options.

BrainrotBase income
Karkerkar Kurkur$120K/s
Blackhole Goat$125K/s

These are great stepping stones if you are trying to reach Celestials and beyond. They can carry your income well before the highest rarities start showing up.

B tier: Hacked, Divine, Secret

These are strong, but they are usually transitional once you are pushing for the highest zones.

RarityBrainrotBase income
HackedAlessio$27.5K/s
HackedTripi Tropi Tropa Tripa$28K/s
DivineWL$15K/s
DivineGirafa Celeste$16K/s
SecretBombini Gusini$4.7K/s
SecretCastlino Fortini$5K/s

C tier: Godly and Mythic

These help a lot in the middle of progression, but they eventually get outclassed.

RarityBrainrotBase income
GodlyBombardiro Crocodilo$3.1K/s
GodlyRhino Toasterino$2.8K/s

Best mutations for the best brainrots

Mutations matter a lot in Kick a Lucky Block. The in-game list shows that mutations apply a multiplier to the base income, so a strong brainrot with a great mutation can become dramatically better.

Here are the most important mutations to look for:

MutationMultiplier
Rainbowx40
Astralx50
Electrifiedx16
Shadowx12
Radioactivex8
Plasmax4
Diamondx2
Goldx1.5

Best mutation combinations to chase

In practice, these are the combinations that matter most:

PriorityBest use case
Rainbow on high-rarity brainrotsThe strongest realistic goal for many players
Astral on top-end brainrotsBest possible scaling in the current list
Electrified on Celestials or OGsVery strong upgrade if you cannot find Rainbow
Shadow on good midgame brainrotsExcellent if you are still progressing
Radioactive on strong base unitsGreat early-to-mid power spike

What the latest update suggests about the best brainrot

In recent player footage, the strongest confirmed in-run result was a Rainbow Dragonfrutina Dolphinita at 211 trillion per second after upgrades and base setup. That lines up with what the public brainrot list suggests: a Celestial with a huge mutation can outperform many lower-tier drops.

The same footage also shows players frequently replacing earlier dragons and mid-tier brainrots with stronger late-game units like E-sock circles and Celestials. That tells you the practical goal is not just rarity alone, but getting a strong rarity plus a top mutation.

How to get better brainrots faster

You do not need a secret trick. The safest and most consistent way to improve is to push the systems that unlock better drops.

Focus on these first

  • Increase kick power so the Lucky Block reaches better zones.
  • Use max luck boosts when available.
  • Keep upgrading your base so you can afford stronger setups.
  • Replace weaker brainrots as soon as a better one gives more income.
  • Rebirth when it helps you rebuild faster.
  • Check the current index in-game after updates, because new brainrots are added over time.

What to prioritize by game stage

Game stageBest priority
Early gameStronger kick power and basic income brainrots
MidgameMythic, Godly, and Divine upgrades
Late gameOG, Celestial, and Eternal brainrots
EndgameAbyssal brainrots and top mutations

Best brainrot for most players

If you want the simplest answer, here it is:

  • Best overall rarity: Abyssal
  • Best practical late-game target: Eternal and Celestial with strong mutations
  • Best mutation to chase: Rainbow
  • Best “good enough” mutation: Electrified or Shadow

If you are not yet at the very top, a well-mutated Celestial can still be one of the best brainrots in your base for a long time.
