Update on February 1st, 2026: Added the new information for Fuse Machine in Steal a Brainrot.
The Fuse Machine is coming back again with the Return update in Steal a Brainrot. Just like back then, this feature lets you combine your existing Brainrots to create brand new ones. If you’ve been collecting Brainrots and want to unlock some more exclusive characters, this guide will show you everything you need to know about how to use the Fuse Machine in Steal a Brainrot.

How to Use the Fuse Machine in Steal a Brainrot
The Fuse Machine is a tool that lets you mix different Brainrots together to make completely new ones. The cost to use the Fuse Machine varies, but it starts from $500 in-game currency. The timings to fuse Brainrots are also different each time, and the shortest time is 15 minutes based on the rarities of Brainrots you submit.
And here’s what makes this machine special: Each player gets their own Fuse Machine, so you don’t have to wait in line or compete with others. You can use it whenever you want at your own pace. Using the Fuse Machine is pretty easy once you know the steps. Here are the steps:
- You’ll need to grab Brainrots from your base and bring them to the Fuse Machine next to the Shop.
- The machine can hold up to 4 Brainrots , but you need to submit them one by one. You can experiment with different combinations to see what works best.
- When you put your Brainrots in, there will be a prompt showing the time it needs to fuse and the money you need to pay . Confirm if you agree to do it.
- Wait until the fusion is ready. Then go back to the Fuse Machine, and hold the E key to claim your new Brainrot . It will give you one new Brainrot from a pool of many possible options.

The quality of what you put in mattered a lot. If you threw in higher rarity brainrots, you had better chances of getting something rare back. The machine could spit out anything from Common to Secret brainrots, so there was always a bit of luck involved.

When the machine first launched last year, there were 15 Brainrots , which come in different rarities. Some are Common, others are Rare and even Brainrot God . On the upcoming Return update, Sammy will add 8 more brainrots from Mythic to Secret rarities.
