❓ Frequently Asked Questions

What is the best brainrot in Steal a Brainrot?

Strawberry Elephant is currently the #1 brainrot with the highest income ($750M/s) and trading value. However, it's extremely rare with only ~2,000 copies in existence. For realistically obtainable brainrots, Griffin ($400B, $400M/s) is considered the best choice.

How do I protect my brainrots from being stolen?

Purchase slappers and troll gear from the in-game shop. Higher-tier slappers provide better protection. You can also set up traps and defensive structures around your base to deter thieves.

What are Lucky Blocks?

Lucky Blocks are special items that, when opened, spawn random brainrots with varying rarities. Some Lucky Blocks (like the Octo Lucky Block from the Summer 2026 update) contain exclusive brainrots not available elsewhere.

How do mutations work?

Mutations multiply a brainrot's base value and income. Only one mutation can be active at a time. Phantom (12x) is currently the highest, followed by Cyber (11x). Events often introduce limited-time high-tier mutations.

When should I rebirth?

Rebirth is worth doing when the permanent multiplier bonus will help you progress faster than continuing without it. Generally, rebirth when your income has slowed down and a multiplier boost would significantly accelerate your progression to higher-tier brainrots.
