Brainrot Tiers
The game has 10 rarity tiers. Higher tiers earn significantly more per fish.
| Tier | Example | Earnings/Fish |
|---|---|---|
| Common | Tung Tung Sahur | $100 |
| Uncommon | Pipi Potato | $300 |

Eggs
Eggs hatch into brainrots. Better eggs have higher chances of rare brainrots.
The conveyor belt shows timers for rare eggs. Epic, Legendary, and higher eggs spawn on timers. Wait for these rather than buying Commons after the first hour.
Mutations
Weather events spawn randomly every 30 minutes and last 5 minutes. Eggs hatched during weather events get permanent mutations.
| Weather | Mutation | Multiplier |
|---|---|---|
| Snowy | Snowy | 1.5x |
| Sakura | Sakura | 1.6x |
| Tornado | Tornado | 1.7x |
| Thunderstorm | Lightning | 1.9x |
| Radioactive | Radioactive | 2.1x |
| Galaxy | Galaxy | 2.4x |
| Disco | Disco | 3x + 50% faster |
Disco only spawns during Admin Abuse events.
Variants
Brainrots can also have variants that stack with mutations:
- Gold - 1.5x fish price
- Diamond - 2x fish price
Fish Index
Catching different fish types fills your Fish Index. Milestones give permanent cash bonuses:
| Fish Types | Bonus |
|---|---|
| 10 | +10% |
| 25 | +25% |
| 50 | +50% |
| 100 | +100% |
These bonuses survive rebirth.
Rebirth
Rebirth resets your brainrots and cash but gives permanent multipliers. Your Fish Index progress stays.
Rebirth when progress slows significantly. The multipliers compound over time.
Crafting Machine
Some brainrots are only available through crafting:
- Tukanno Bananno (Legendary) - $32K/fish
- Karkerkarkurkur (Mythic) - $350K/fish
- Dul Dul Dul (Secret) - $4.5M/fish
- Cocosini Mama (Exotic) - $20M/fish
Crafted brainrots are guaranteed rather than RNG-based.
Early Game Strategy (First Hour)
Priority 1: Fill Your Slots
Buy the cheapest eggs to fill all available brainrot slots. Any brainrot fishing is better than empty slots.
Priority 2: Save for Better Eggs
After filling slots, stop buying Commons. Save cash for Rare and Epic eggs when they appear on the conveyor.
Priority 3: Watch for Weather
When weather events spawn, hatch eggs during them to get mutations. Even a mutated Common is better than a normal Rare.
Mid Game Strategy
Upgrade Focus
Upgrade your highest rarity brainrots first. A maxed Epic earns more than several unupgraded Legendaries.
Rebirth Timing
Rebirth when:
- Upgrade costs exceed several minutes of income
- Progress has stalled
- The rebirth multiplier is meaningful
Don't rebirth when:
- You just hatched a high-rarity brainrot
- You're close to a Fish Index milestone
- You're still making good progress
Build Fish Index
Keep some variety in your brainrot lineup. Different brainrots catch different fish types, filling your index faster.
Attend Admin Abuse
Admin Abuse events spawn Disco weather (3x multiplier + 50% speed). This mutation is only available during these events. Check the game's Roblox page for schedules.
Late Game Strategy
Target High Tiers
Focus on Mythic and above. The earnings gap between tiers is massive at high levels.
Stack Mutations
Use the Mutation Combiner to stack multiple mutations on your best brainrots. Mutations multiply together.
A Disco + Galaxy brainrot has a 7.2x multiplier (3x × 2.4x).
Craft Exclusives
Crafted brainrots like Karkerkarkurkur and Cocosini Mama are often the best in their tier. Prioritize crafting them.
Complete Fish Index
The 100% bonus from completing the Fish Index doubles all earnings permanently.

FAQ
When should I rebirth? When progress has stalled and the rebirth multiplier is at least 2x your current rate.
What's the best mutation? Disco (3x + 50% speed), but it only spawns during Admin Abuse events. Galaxy and Magmatic (2.4x) are the best from natural weather.
Should I keep low-tier mutated brainrots? Yes, until you can transfer their mutation using the Mutation Combiner.
How do I get Divine brainrots? Divine eggs spawn rarely on the conveyor. The price is in the quadrillions, so it's a late-game goal.
