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.
| Tier | Brainrots | Why they rank here |
|---|---|---|
| S+ | Abyssal brainrots | Highest base income seen in the current list |
| S | Eternal brainrots | Very strong income and top-tier for long-term grinding |
| A+ | Celestial brainrots | Huge upgrade over lower rarities, especially with mutations |
| A | OG brainrots | Excellent income and often worth keeping for a while |
| B | Hacked, Divine, Secret | Strong mid-to-late game options |
| C | Godly, Mythic | Good early progression, but quickly replaced |
| D | Legendary and below | Fine 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.
| Brainrot | Base 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.
| Brainrot | Base 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.
| Brainrot | Base 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.
| Brainrot | Base 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.
| Rarity | Brainrot | Base income |
|---|---|---|
| Hacked | Alessio | $27.5K/s |
| Hacked | Tripi Tropi Tropa Tripa | $28K/s |
| Divine | WL | $15K/s |
| Divine | Girafa Celeste | $16K/s |
| Secret | Bombini Gusini | $4.7K/s |
| Secret | Castlino Fortini | $5K/s |
C tier: Godly and Mythic
These help a lot in the middle of progression, but they eventually get outclassed.
| Rarity | Brainrot | Base income |
|---|---|---|
| Godly | Bombardiro Crocodilo | $3.1K/s |
| Godly | Rhino Toasterino | $2.8K/s |
| Godly | Orangutini Ananasini | $2.7K/s |
| Mythic | Glorbo Fruttodrilo | $920/s |
| Mythic | Bangello | $725/s |
| Mythic | Chef Crabracadabra | $600/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:
| Mutation | Multiplier |
|---|---|
| Rainbow | x40 |
| Astral | x50 |
| Electrified | x16 |
| Shadow | x12 |
| Radioactive | x8 |
| Plasma | x4 |
| Diamond | x2 |
| Gold | x1.5 |
Best mutation combinations to chase
In practice, these are the combinations that matter most:
| Priority | Best use case |
|---|---|
| Rainbow on high-rarity brainrots | The strongest realistic goal for many players |
| Astral on top-end brainrots | Best possible scaling in the current list |
| Electrified on Celestials or OGs | Very strong upgrade if you cannot find Rainbow |
| Shadow on good midgame brainrots | Excellent if you are still progressing |
| Radioactive on strong base units | Great 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 stage | Best priority |
|---|---|
| Early game | Stronger kick power and basic income brainrots |
| Midgame | Mythic, Godly, and Divine upgrades |
| Late game | OG, Celestial, and Eternal brainrots |
| Endgame | Abyssal 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.
Quick checklist for choosing your next upgrade
Use this checklist before replacing a brainrot:

| Does it earn more per second? | Always compare actual income |
| Will it fit your current base strategy? | Some upgrades are better for cash flow than others |
| Can you safely reach the zone? | Don’t overextend and lose the drop |
