Steal a Brainrot rarity tiers explained

Rarity is the starting point

Every brainrot has a rarity tier, shown by its color. Higher tiers are far rarer, cost more to grab off the conveyor, and earn a lot more cash per second. Rarity is the first thing that sets a brainrot's value — but it's only the start, because mutations and traits can multiply it from there.

The nine tiers, low to high

• Common — the everyday brainrots, lowest value.
• Rare — a small step up.
• Epic — getting harder to find.
• Legendary — properly sought-after.
• Mythic — high-end, serious trading starts here.
• Brainrot God — top of the regular ladder.
• Secret — extremely rare, very high value.
• OG — one of the rarest tiers in the game.
• Admin — Admin Abuse / event-only brainrots, the highest tier of all.

Mutations (a brainrot has at most one)

A mutation changes a brainrot's appearance and multiplies its value and income. A brainrot can only ever carry ONE mutation — they don't stack with each other.

• Common ones: Gold and Diamond (small multipliers).
• Mid-range: Bloodrot, Candy, Lava, Galaxy.
• Top-end: Rainbow and Phantom carry the biggest multipliers.
• Only one applies at a time — a Gold brainrot can't also be Rainbow.

Traits (these stack)

Traits are permanent boosters earned from events. Unlike mutations, a brainrot can carry several traits at once, and they stack — so a brainrot with a few strong traits is worth far more than the plain version.

• Strawberry and Meowl are among the strongest single traits.
• Others like John Pork and Skibidi add their own boost on top.
• Traits come from events (Admin Abuse, seasonal, ritual and weather events) and stay on the brainrot for good.
• More traits = more value, because each one adds to the total.

How values add up

Values here are a relative community scale — reference points to keep trades fair, never real-money prices. A baseline brainrot like La Vacca Saturno Saturnita sits near 1, while the rarest Admin brainrots (think Kings Coleslaw) climb toward 100,000. Rarity sets the base, then the mutation and any traits multiply it, so two brainrots with the same name can be worth wildly different amounts.

• Rarity tier sets the base value.
• The one mutation multiplies it.
• Each stacked trait multiplies it further.
• Run both sides through the free Win / Fair / Lose calculator to see if a trade is roughly even before you commit.

What to check before you trade

Trades are item-for-item and happen in-game — you open the trade interface, both players add the exact brainrots (and any Seasonal Base Skins) you agreed on, and both confirm before anything swaps.

• Match the rarity, the mutation, AND every trait — not just the name.
• Confirm the Roblox @username matches the person you arranged with.
• Only trade what's shown in the trade window now — never hand a brainrot over first or 'add later'.
• Re-check the window right before you press confirm, in case anything was swapped.
