The Cursed Mutation in Steal a Brainrot is one of the most valuable limited-time upgrades available in the game. It multiplies a Brainrot's income by nine times and gives it a striking red-and-black appearance. The mutation is only available during Cursed Events, which last 15 minutes and repeat every three hours. This makes timing and preparation essential for anyone who wants to collect these powerful units.
Cursed Mutations not only increase income but also make your collection visually impressive. Collecting a large number of Cursed Brainrots also unlocks the Cursed Base cosmetic skin, a reward for achieving 75 percent of the full Cursed collection.
Understanding the Cursed Event
Cursed Mutations appear exclusively during Cursed Events, which are short and repeat at fixed intervals. Each event lasts 15 minutes and occurs every three hours. During the event, the game map changes its appearance with deep red and black tones, symbols appear on walls, and a large monster head appears near the red conveyor belt entrance. These cues tell you when to focus entirely on mutation collection.
Players should also be aware of Admin Abuse periods. During these special sessions, the game can spawn extra Cursed content, increasing the chance to obtain rare mutations.
Steal a Brainrot Guide: How to Get Cursed Mutation
How to Get Cursed Mutation
There are three main ways to obtain Cursed Mutations: conveyor belt spawns, Cursed Spin Wheel, and stealing from other players.
Conveyor Belt Spawns
The primary acquisition method involves camping the conveyor belt during active Cursed Events. Mutated Brainrots spawn randomly among regular units and appear with their distinctive red-black coloring. You can purchase these at standard prices with no extra cost for the mutation.
Competition runs intense during peak hours. Multiple players target the same spawns, creating a race for E key reactions. Position yourself strategically near the conveyor entrance, keeping your camera angle optimized for quick identification. The moment you spot that red glow, purchase immediately.
Server selection matters significantly here. Fresh servers with lower player counts reduce competition for spawns. However, high-population servers sometimes trigger more frequent spawn rates. Test both approaches to determine which works better for your playstyle.
Important
Cursed Mutation Brainrots cost identical amounts to their regular versions. The mutation adds value without increasing purchase price.
Cursed Spin Wheel Rewards
The Cursed Spin Wheel appeared alongside the mutation update, positioned beside the central Shop area. This wheel offers six possible rewards, with the Cursed Secret Lucky Block representing the ultimate prize at just 0.5% drop rate.
You'll receive one free spin every hour. Additional spins require Robux purchases, though buying spins grants 2x Luck multiplier for improved odds. The Cursed Secret Lucky Block contains guaranteed rare Brainrots with Cursed Mutation applied, making it the most efficient single-spin reward possible.

Strategic Stealing Tactics
Stealing represents the fastest path to Cursed Mutations for aggressive players. During active events, many players purchase Cursed Brainrots and immediately return to their bases for storage. This creates perfect raid opportunities.
Scout player bases during the first 5 to 7 minutes of each Cursed Event. Watch for players making multiple trips from the conveyor to their base as they are likely stockpiling fresh mutations. Position yourself near their base entrance, waiting for them to deposit units and leave.
Hold E on targeted Cursed Brainrots to initiate the steal. The moment you grab one, sprint toward your base using your fastest movement abilities. Expect the original owner to chase immediately.
Warning
Pre-place traps outside your base before stealing. Loop pursuers through trap zones to secure your stolen mutations safely.
