Rainbow is one of the best mutations in Steal a Brainrot. It multiplies a brainrot's income by 10, and unlike most big mutations it isn't locked to a one-off event. Here's how to get one.
1. Watch the Red Carpet
Every brainrot that walks in on the Red Carpet has a small chance to be Rainbow, around 1%. Gold and Diamond are much more common, so most of what you see won't be Rainbow. If you spot one, grab it fast, because other players will be going for it too.
2. Use luck boosts
Server luck boosts raise the odds of rare mutations while they're active. That's the best time to stay in a server and keep an eye on the carpet.
3. Steal one
It's in the name. If another player has a Rainbow brainrot on their base, you can try to steal it. Just remember they can do the same to you, so lock your base when you've got something good.
4. Trade for it
Some players will trade a Rainbow for the right offer. Check what your brainrots are worth first so you don't give away more than you need to.
5. Buy it
If you'd rather not wait for a 1% spawn, you can buy Rainbow brainrots from us. Go to Steal a Brainrot and pick Rainbow in the mutation list to see every Rainbow brainrot we have in stock and its price.
Once you've paid, open your order from the link in your confirmation email, link your Roblox account and chat with us while we deliver. Most orders arrive in-game within 1 to 20 minutes, and we never ask for your password.
Is Rainbow worth it?
For most players, yes. A 10x boost is huge, and Rainbow is usually cheaper than top limited mutations like Crystal or Eclipse. Put it on a brainrot that already earns well and you'll feel the difference straight away.
