Steal a Brainrot Cursed Mutation Guide — March 2026

Steal a Brainrot just dropped its most sinister update yet: the Cursed Mutation. Your brainrots can now turn evil with a red cursed aura, a brand-new Cursed Spin Wheel is live, and the game is teasing a full Duels system arriving next week.

Here is everything you need to know about the Cursed Mutation update and how to take advantage of it.

What Is the Cursed Mutation?

The Cursed Mutation is a new mutation type that applies a red evil aura to any brainrot. Unlike standard mutations, cursed brainrots have unique visual effects and appear in the brand-new Cursed Index — a separate collection tracker for all cursed variants.

Cursed brainrots are obtained through the Cursed Spin Wheel, a new machine that costs in-game currency to spin. Each spin has a chance to apply the cursed mutation to one of your existing brainrots or grant you a cursed secret block.

Cursed Spin Wheel

The Cursed Spin Wheel is located in the main hub area. Here is what you need to know:

The Cursed Secret Block is a new collectible that only drops from this wheel. These blocks are already commanding premium trade values since the supply is limited to event spins only.

Pro tip: Farm currency before spinning. The wheel is expensive at higher rebirth levels, and you want enough for at least 10-15 spins per session to make the pity system work in your favor.

This adds a whole new layer of collecting on top of the existing brainrot collection. Expect cursed variants of rare brainrots to become some of the most valuable items in the trading economy.
