OG brainrots generate $2M+/second and require 280+ Speed to farm. Divine brainrots hit $100K-500K/second at 180 Speed. For most players, Secrets ($5K-20K/second at 100 Speed) are the realistic endgame. Everything below Mythic is temporary filler you'll replace within hours.
I've been grinding this game since launch, and the income gaps between tiers are massive. A single Divine brainrot outearns a full base of Legendaries. Focus on climbing tiers, not collecting within tiers.
Tier List Summary
| Tier | Brainrots | Verdict |
|---|---|---|
| S+ | OG | Endgame gods, 280+ Speed required |
| S | Divine, Exclusive | Top tier, worth the grind |
| A | Brainrot God, Secret | Late-game core |
| B | Mythic | Mid-game staple |
| C | Legendary, Epic | Early progression |
| D | Rare, Common | Replace immediately |
S+ Tier: OG Brainrots
Income: $2M-5M+/second
Zone Speed: 280+
Verdict: The absolute best. If you can farm OG zone, nothing else matters.
OG brainrots spawn at the far end of the map where waves originate. You need serious speed investment and perfect wave timing to grab these. Most players never touch OG zone.
A single OG brainrot at Rebirth 10 generates more income than a full base of Secrets. If you're pushing endgame, OG is the goal.
S Tier: Divine & Exclusive
Divine Brainrots
Income: $100K-500K/second
Zone Speed: 180
Verdict: Realistic endgame for dedicated players.
Divine zone is achievable with focused grinding. The income jump from Brainrot God to Divine is 5-10x. A base full of Divines at R10 generates billions per second.
Exclusive Brainrots
Income: $500K-2M/second
Zone Speed: 220
Verdict: Between Divine and OG. Worth farming if you can reach it.
Exclusive zone sits between Divine and OG. The brainrots here are excellent, but the speed requirement is steep. Most players skip straight from Divine farming to OG attempts.
A Tier: Brainrot God & Secret
Brainrot God
Income: $20K-100K/second
Zone Speed: 140
Verdict: The gateway to endgame. Farm these heavily.
Brainrot God zone is where the game shifts from "grinding" to "progressing." The income jump from Secret to Brainrot God is significant. A fused Brainrot God can compete with unfused Divines.
Secret
Income: $5K-20K/second
Zone Speed: 100
Verdict: Late-game staple. Most players spend hours here.
Secret brainrots are the first tier that feels "worth it." A full base of Secrets generates enough income to push for higher zones. This is where I spent most of my mid-game.
B Tier: Mythic
Income: $1K-5K/second
Zone Speed: 80
Verdict: Solid mid-game. Replace with Secrets when possible.
Mythics are the transition tier. They're good enough to progress but not good enough to keep long-term. Use them to fund your push to Secret zone, then replace them.
A fused Mythic can outperform an unfused Secret, so don't ignore the Fuse Machine.
C Tier: Legendary & Epic
Legendary
Income: $200-1K/second
Zone Speed: 60
Verdict: Early progression. Replace with Mythics.
Legendaries feel good when you first get them, but the income gap to Mythics is brutal. Don't invest in upgrading Legendaries. Save resources for higher tiers.
Epic
Income: $50-200/second
Zone Speed: 40
Verdict: Starter tier. Replace quickly.
Epics are your first "real" brainrots. They generate enough income to start progressing, but you'll replace them within your first few hours.
D Tier: Rare & Common
Rare
Income: $10-50/second
Zone Speed: 20
Verdict: Filler. Replace immediately.
Rares exist to fill slots until you find something better. Don't upgrade them, don't fuse them, just replace them.
Common
Income: $1-10/second
Zone Speed: 0
Verdict: Garbage. Never keep these.
Commons are worthless. The income is so low that a single Epic outearns 20+ Commons. Replace them the moment you find anything else.
Income Comparison at Rebirth 10
| Tier | Base Income | R10 Income |
|---|---|---|
| OG | $3M/sec | $225M/sec |
| Divine | $300K/sec | $22.5M/sec |
| Brainrot God | $50K/sec | $3.75M/sec |
| Secret | $10K/sec | $750K/sec |
| Mythic | $3K/sec | $225K/sec |
| Legendary | $500/sec | $37.5K/sec |
The R10 multiplier (75x) makes tier differences even more extreme. A single OG at R10 generates more than 300 Legendaries combined.
Mutation Multipliers
Mutations stack with rebirth multipliers:
| Mutation | Multiplier |
|---|---|
| Normal | 1x |
| Shiny | 2x |
| Golden | 3x |
| Rainbow | 5x |
| Radioactive | 10x |
A Radioactive Divine at R10: $300K × 10 × 75 = $225M/second from a single brainrot. That's why mutation hunting during events matters.
What to Farm at Each Stage
R0-R3: Anything you can reach. Fill slots, rebirth fast.
R3-R5: Target Mythics and Secrets. Replace everything below Legendary.
R5-R7: Farm Secrets and Brainrot Gods. Start replacing Mythics.
R7-R10: Push for Divine zone. Replace Secrets with Brainrot Gods and Divines.
R10+: Farm Divine and OG. Hunt mutations during events.
Fusing Priority
Fuse duplicates in this order:
- Commons/Rares should be fused immediately since you're replacing them anyway
- Epics/Legendaries can be fused if you have duplicates, but don't farm for them
- Mythics require strategic fusing since a fused Mythic competes with unfused Secrets
- Secrets and above should only be fused if you have 3+ copies to keep diversity
Don't fuse your only copy of a high-tier brainrot. The income boost from fusing isn't worth losing a slot.
Common Mistakes
Keeping Commons/Rares. The income is worthless. Replace them immediately.
Upgrading low-tier brainrots. Save resources for Secrets and above.
Ignoring mutations. A Shiny Mythic beats a normal Secret. Check mutations before replacing.
Rushing zones you can't survive. Farm the zone you can handle consistently. Dying wastes time.
Skipping rebirths. The multipliers make every brainrot better. Rebirth early and often.
