Brainrot Tier List
Ranks every Brainrot family by income, Rebirth requirement, and meta value as of Update 3.
Brainblast a Lucky Block runs on Brainrots — the collectible units you spawn from Lucky Blocks and slot into your Base to earn passive cash. Picking the right unit for each slot is the single biggest lever you can pull on income, and it is what separates a casual grinder from a Rebirth 5+ player.
This tier list ranks every Brainrot family we have observed in the live game after Update 3. The list is sorted by passive income per second (the dominant metric) and cross-referenced with Rebirth gating so you know which units are worth chasing now and which are placeholder filler.
Tier List Summary
| Tier | Brainrot Family | Income (per sec) | Notes |
|---|---|---|---|
| S | Celestials | $10M+ | Endgame. Rebirth 8 gating. |
| S | Eternals | $5M – $10M | Top earner per slot. |
| S | Transcendents | $3M – $5M | Snowball your Rebirth loop. |
| A | Brainrot God | $500K – $2M | Mid-late core units. |
| A | Secret Brainrots | $50K – $400K | Reliable earners, Rebirth 6-7. |
| B | Mythic | $5K – $50K | Bridge between early and late. |
| B | Legendary | $1K – $5K | Stable mid-game income. |
| C | Epic – Common | < $1K | Replaceable early game. |
How We Ranked Brainrots
The metric we lean on hardest is passive income per second because every other system in Brainblast a Lucky Block ultimately feeds that number:
- Brain Power — Determines how far your Lucky Block flies. Higher-tier zones drop higher-tier Brainrots.
- Base Income — Determined by which Brainrots you have placed. Higher tiers multiply faster.
- Rebirth Multiplier — Compounds on top of base income. Stacking S-tier Brainrots lets you rebuild power in minutes rather than hours.
We also penalise units that are locked behind Rebirth gates you cannot reach yet, so the S-tier reflects what an experienced player should chase — not what a brand-new account should expect.

Each tier has its own dedicated page with a longer breakdown, recommended placement order, and slot-by-slot advice.
- S-Tier Brainrots — best-in-slot units for endgame income
- A-Tier Brainrots — stable mid-late earners
- B-Tier Brainrots — bridge units for new players
- C-Tier Brainrots — placeholder units to swap out fast

Frequently Asked Questions
Quick answers to the most common questions.
How is the Brainblast a Lucky Block tier list ranked?
We rank by passive income per second, then cross-check against Rebirth gating so the list is useful for both new and experienced players.
Which tier should a new player focus on?
Place any Brainrot you unlock — empty pedestals earn nothing. Then start replacing C-tier units with Mythic or higher once your income stabilises.
Do Brainrots have mutations?
Yes. Mutated Brainrots earn a multiplier on top of their base income. We list the most valuable ones inside the S-tier breakdown.
Can the tier list change with updates?
Yes. Update 3 added new event Brainrots that we are tracking. We re-rank the list after every major patch.
Is there a way to preview a Brainrot before unlocking it?
Player videos on YouTube cover every released unit. Our embedded guide videos walk through each tier visually.
