Steal a Brainrot: How to Use the Rainbow Machine and Get Rainbow Characters

Steal a Brainrot is a fun and exciting Roblox game where you build your base and collect characters. Each character has a rarity, and some of them have special mutations. These mutated versions are stronger and more valuable than the regular ones.

One of the rarest and most powerful mutations in the game is the Rainbow mutation. These characters shine with colorful effects and give you more income than normal ones. However, Rainbow characters are very hard to find.

Thankfully, the developers have added a feature called the Rainbow Machine. It can help increase the chances of getting Rainbow characters on the ramp.

In this guide, you’ll learn:

• What the Rainbow Machine is
• How to use it
• Ways to improve your chances of getting Rainbow characters
• Tips to stay safe from other players
• Common questions answered

Let’s get started.

What Is the Rainbow Machine?

The Rainbow Machine is a special machine in Steal a Brainrot. You can find it next to the Shop area in the game. This machine helps you and other players spawn Rainbow characters more often.

It works like this:

1. You deposit Golden Brainrot characters into the machine.
2. Once the required number of characters is added, the machine turns on.
3. When activated, it makes Rainbow characters appear more frequently for 15 minutes in that server.
4. The top of the machine shows rainbow-colored light when it’s active.

This feature is great for players who want a better chance of collecting the rarest characters without depending only on luck.

How to Fill the Rainbow Machine

To use the Rainbow Machine, you need to fill it up first. Here’s how to do that:

1. Steal characters with the Golden mutation.
2. Walk up to the Rainbow Machine.
3. Deposit those Golden characters into the machine.
4. Check the counter next to it to see how many more you need.

At first, the machine asks for 15 Golden Brainrots. But after each use, the number increases. For example:

• 1st time: 15 Goldens
• 2nd time: 25 Goldens
• 3rd time: 50 Goldens
• 4th time: 75 Goldens
• And so on…

As you can see, it gets harder each time.

Important Tip: It’s almost impossible to steal that many Golden characters alone in public servers. Other players may steal your progress. That’s why most experienced players team up in private servers to activate the machine safely.

How Long Does the Rainbow Machine Work?

Once the Rainbow Machine is activated, the boost lasts 15 minutes.

During this time:

• Rainbow characters will spawn more often on the ramp.
• Any player in the server can buy them if they have enough money.
• The machine cannot be reactivated until the timer runs out.
• You cannot stack the effect by adding more Golden Brainrots.

So, plan your 15 minutes carefully. Make sure you’re ready to buy or steal Rainbow Brainrots during this short time.

Can You Use Robux Instead?

Yes! If you don’t have enough Golden characters or just want a quick way to activate the machine, you can spend 199 Robux to fill it instantly.

Each time you choose the “Fill Now” option:

• It skips the deposit process.
• The machine activates right away.
• You still get the 15-minute spawn bonus.

This is a good option for players who want fast results or don’t want to lose their characters.

How to Get Rainbow Characters Faster

Rainbow characters are very hard to get because they have a very low spawn chance. But you can increase your odds by using some smart tricks.

Here are a few helpful tips:

1. Use the Rainbow Machine (with Goldens or Robux)

The main way to increase Rainbow character spawn is by activating the Rainbow Machine. It’s the most reliable method in the game.

2. Use Rainbow Spins for Server Luck

If you spin the Rainbow Wheel, sometimes you can win 10x server luck. When this effect is active, Rainbow characters spawn more often during regular gameplay.

Keep spinning until you get this powerful boost. It stacks well with the Rainbow Machine for maximum effect.

3. Play in Private Servers with Friends

Private servers cost 79 Robux per month, but they give you complete control. You can invite trusted friends and work together.

Benefits of private servers:

• No strangers can steal your characters.
• You can safely deposit Goldens.
• You get more time to focus on finding Rainbow Brainrots.
• Shared teamwork makes progress faster.

4. Stay Ready Near the Ramp

Keep your base protected, but always stay near the ramp when the machine is active. Rainbow characters appear randomly, and you don’t want to miss them.

Have enough money saved before using the machine. That way, you can buy them quickly without waiting.

Base Protection Tips

In Steal a Brainrot, other players can steal your characters if your base is open.

Here are a few tips to keep your Rainbow and Golden characters safe:

• Lock your base at all times.
• Always return to your base before the door timer ends.
• If you’re outside for too long, your base opens, and players can rush in.
• Use walls or traps if available to slow down intruders.

Protecting your rare Brainrots is just as important as collecting them.
