Complete Steal a Brainrot Mutation Tier List

Mutations in Steal a Brainrot are special modifiers that randomly appear on Brainrots when they spawn on the conveyor belt. These mutations not only change the visual appearance of your Brainrots but also provide substantial multipliers to their income generation. Understanding which mutations are most valuable can help you make smarter decisions about which Brainrots to purchase and which to let pass by.

Ranking Methodology

Our tier list is based on several key factors:

• Income Multiplier: The primary factor determining a mutation’s value
• Rarity: How frequently the mutation appears naturally
• Availability: Whether the mutation can be obtained normally or requires admin intervention
• Stacking Potential: How well the mutation works with traits for maximum income

S-Tier Mutations: The Ultimate Money Makers

S-Tier mutations represent the pinnacle of income generation in Steal a Brainrot. These rare mutations provide massive multipliers that can transform your earning potential overnight.

Rainbow Mutation (10x Multiplier)

Status: Available (Rare) The Rainbow mutation is the holy grail of Steal a Brainrot mutations, offering an incredible 10x income multiplier. Brainrots with this mutation display a vibrant rainbow texture that makes them instantly recognizable. While available naturally, the Rainbow mutation is extremely rare and should be prioritized whenever it appears, regardless of the Brainrot’s base value.

Pro Tip: During the Rainbow Machine admin event, the chances of spawning Rainbow mutations increase significantly. Keep an eye on the official Discord for event notifications.

Strawberry Mutation (8x Multiplier)

Status: Available (Event Only) The Strawberry mutation provides an impressive 8x multiplier and features a distinctive pink texture with a stem hat. This mutation can only be obtained when a Strawberry Elephant spawns in your server, making it one of the most sought-after event-exclusive mutations.

Strategy: If you see a Strawberry Elephant on the conveyor belt, consider purchasing it even if it’s expensive – the 8x multiplier will quickly justify the investment.

Yin Yang Mutation (7.5x Multiplier)

Status: Available (Trigger Only) Offering a 7.5x multiplier, the Yin Yang mutation is only available during specific Yin Yang events. Brainrots with this mutation display the classic yin-yang symbol and provide substantial income boosts. While not as rare as Rainbow, it’s still considered a top-tier mutation due to its high multiplier.

A-Tier Mutations: Excellent Income Boosters

A-Tier mutations offer substantial income improvements and are more accessible than S-Tier options, making them excellent choices for most players.

Lava Mutation (6x Multiplier)

Status: Available (Rare) The Lava mutation gives Brainrots a fiery appearance with a 6x income multiplier. While not as rare as Rainbow, Lava mutations are still uncommon and should be prioritized when they appear. The visual effect includes glowing orange-red textures that make mutated Brainrots stand out.

Glitch Mutation (6x Multiplier)

Status: Available (Trigger Only) Glitch mutations provide the same 6x multiplier as Lava but are only available during Glitch events. These Brainrots display glitchy visual effects and digital artifacts, making them easy to identify. During Glitch events, the map turns dark and glitch-themed, with Brainrots occasionally falling into glitch holes to receive this mutation.

Galaxy Mutation (6x Multiplier, 7x during events)

Status: Available (Rare) The Galaxy mutation offers a 6x multiplier normally, but this increases to 7x during special Galaxy events. Brainrots with this mutation display a beautiful purple cosmic aura. According to recent developer tweets, new Galaxy mutation features were introduced in August 2025, making this mutation even more valuable.

B-Tier Mutations: Solid Performance

B-Tier mutations provide good income boosts but are typically only available through admin intervention, making them less accessible for regular players.

Celestial Mutation (4x Multiplier)

Status: Admin Trigger Only The Celestial mutation offers a 4x multiplier with a cosmic starry appearance. However, this mutation is no longer available through normal means and can only be spawned by administrators during special events.

Candy Mutation (4x Multiplier)

Status: Admin Trigger Only Similar to Celestial, the Candy mutation provides a 4x multiplier with a sweet, colorful appearance. This mutation is also admin-only and cannot be obtained through normal gameplay.

C-Tier Mutations: Limited Value

C-Tier mutations offer minimal improvements and are generally not worth pursuing unless you have no other options.

Bloodrot Mutation (2x Multiplier)

Status: Admin Trigger Only The Bloodrot mutation provides only a 2x multiplier with a dark, bloody appearance. Like other admin-only mutations, it’s no longer available through normal gameplay and offers poor value compared to obtainable options.

D-Tier Mutations: Minimal Impact

D-Tier mutations provide the smallest income boosts but are the most commonly available. While not exciting, they’re better than no mutation at all.

Diamond Mutation (1.5x Multiplier)

Status: Available (Common) The Diamond mutation gives Brainrots a blue crystalline appearance with a modest 1.5x multiplier. While common, this mutation should only be considered for high-value Brainrots where even a small boost is worthwhile.

Gold Mutation (1.25x Multiplier)

Status: Available (Common) The Gold mutation is the most common mutation, giving Brainrots a golden appearance with a 1.25x multiplier. Like Diamond, this mutation is only worth considering for expensive Brainrots where the small percentage increase adds up to significant amounts.

How to Get Mutations in Steal a Brainrot?

Understanding how mutations work and how to increase your chances of getting them is crucial for maximizing your income in Steal a Brainrot.

Natural Mutation Spawning

Mutations appear randomly when Brainrots spawn on the conveyor belt. The system is entirely luck-based, but there are ways to improve your odds:

• Server Luck Gamepass: For 249 Robux, you can purchase the Server Luck gamepass, which doubles the mutation spawn rate in your server.
• Play with Friends: Having more players in your server increases the overall spawn rate of Brainrots, indirectly increasing your chances of seeing mutations.
• Event Participation: During special events, mutation rates are often increased, and exclusive mutations become available.

Admin Events and Exclusive Mutations

Many of the best mutations are only available during admin events. Here’s how to stay informed and participate:

1. Join the Official Discord: The Steal a Brainrot Discord provides real-time notifications for admin events and special mutations.
2. Follow Developer Social Media: The official Twitter account and developer Sammy’s account announce upcoming events and new content.
3. Participate in Rituals: Some mutations can be triggered by completing specific rituals with other players, such as forming triangles or lines with certain Brainrots.

Mutation Stacking with Traits

For maximum income, you want to combine mutations with traits. Traits are separate from mutations and provide additional multipliers that stack with mutation bonuses:

Example Calculation: A Brainrot with a Rainbow mutation (10x) and a Firework trait (6x) would generate 16x the normal income (10 + 6 = 16x).

Some of the best trait combinations include:

• Strawberry Trait (8x) + Rainbow Mutation (10x) = 18x total
• Nyan Trait (6x) + Rainbow Mutation (10x) = 16x total
• Firework Trait (6x) + Rainbow Mutation (10x) = 16x total

Pro Tips for Mutation Hunting

1. Prioritize High-Value Brainrots

When a mutation appears on an expensive Brainrot, it’s often worth purchasing even if the mutation isn’t perfect. A Gold mutation (1.25x) on a $10B Brainrot generates more income than a Rainbow mutation (10x) on a $1B Brainrot.

2. Monitor Event Cycles

Many mutations follow predictable patterns:

• Weather Events: Rain (2.5x), Snow (3x), and Starfall (2.5x) occur naturally
• Timed Events: Halloween (4.5x) and Extinct (4x) events spawn every 2 hours
• Admin Events: Follow the Discord for real-time notifications

3. Build a Balanced Collection

Don’t put all your resources into chasing one perfect mutation. Instead, build a diverse collection with different mutations and traits to ensure steady income from multiple sources.

4. Consider Stealing Opportunities

Sometimes the best way to get rare mutations is to steal them from other players. Keep an eye on other players’ bases and be ready to make strategic steals when valuable mutated Brainrots are left unguarded.
