Steal a Brainrot Tier List — Best Brainrots Ranked

Steal a Brainrot is one of Roblox’s fastest-growing simulation games, letting players “steal” quirky creatures known as Brainrots to generate income over time. Each Brainrot has a rarity, value, and earning rate — making collection strategy a key to progression. As the game evolves, understanding which Brainrots actually perform best helps you avoid wasting time on low earners.

This tier list is based on real data and community consensus mostly from the Steal a Brainrot Wiki.

S-Tier — The Top Earners (Must-Have Brainrots)

The following are the undisputed best Brainrots in the game — offering the highest passive income per minute, extreme rarity, and superior trade value.

• Chimpanzini Spiderini — Secret rarity; a true meta-defining Brainrot capable of generating $100M–$150M+ income.

• Dul Dul Dul — Another Secret pick with equally top-tier output; considered one of the most valuable in the current economy.

• Trenostruzzo Turbo 4000 — Offers massive income while being incredibly hard to steal; highly sought after by collectors.

These Brainrots sit at the top because they outperform all others in efficiency and prestige. If you can secure even one of these, your income snowballs rapidly.

A-Tier — High Performers With Great ROI

A-Tier Brainrots provide strong income and solid availability, making them excellent mid-game or secondary investments.

• High-end Legendary or Mythic Brainrots

• Balanced units that offer consistent $50M–$100M returns

• Easier to obtain than Secret types, but still valuable for trades and progression

Players often use these as stepping stones while grinding toward S-Tier Brainrots.

B & C-Tier — Decent Picks for Progression

These Brainrots are good for early-mid game players who are still expanding their lineup. They don’t compete with top earners but provide stable returns.

• Epic and Rare Brainrots

• Examples: Fluriflura, Talpa Di Fero, Pipi Kiwi

• Usually earn in the $10M–$40M range per cycle

While they won’t make you rich, they’re easy to obtain and a smart way to diversify your setup before hunting higher rarities.

D & F-Tier — Starter or Niche Brainrots

Low-tier Brainrots are often just for completion or nostalgia. Their income potential is minimal, and most players replace them quickly.
Still, a few have cosmetic or event value, making them collectible in their own right.

These can be seem as “for fun only” — useful for experiments or to fill collection slots.

How the Rankings Were Determined

Both Eldorado and community data consider three main factors:

1. Income per Minute – The key metric that defines how profitable a Brainrot is.

2. Rarity and Drop Rate – Secret and God-class Brainrots naturally rank higher.

3. Steal Difficulty – Harder-to-obtain Brainrots often have inflated value due to scarcity.

This ensures the ranking reflects not just income but the overall practicality of owning or farming each Brainrot.
