The new Bros Machine in Steal a Brainrot introduces 10 Secret Brainrots that players can craft by combining specific Brainrots. However, the crafting cost varies considerably depending on which Bros you choose. Some generate over $200M/s but require hundreds of billions to craft, while others offer a cheaper way to add another Secret Brainrot to your base.
Quick Answer
The Bros Machine changes its available crafting target every 15 minutes, while crafting takes 5–60 minutes depending on the selected Bros.
If you're aiming for high income, Scary Bros is my top recommendation. If you'd rather keep your crafting costs down, consider Tang Bros, Spinny Bros, or Noobini Bros.

Which Bros Brainrots Should You Craft First?
The 10 Bros have base incomes ranging from $11M/s to $230M/s. However, the highest income doesn't automatically make one option the best choice for every player. Here are my recommendations based on their confirmed income, crafting costs, and waiting times.
1. Scary Bros – Best Overall
$230M/s
Crafting Cost: $230B | Crafting Time: 60 minutes
Scary Bros generates $230M/s, making it the highest-income option among the 10 regular Bros.
It requires Scarino Crowino and Fishino Clownino, costs $230B to craft, and takes 60 minutes. You can also skip the waiting time for 240 Robux.
If you already have the required ingredients and want a high-income Secret Brainrot, Scary Bros is my top recommendation.
Despite its name, Scary Bros actually looks pretty cute. Whether you're collecting it or looking to boost your base income, it's a great choice.
Mutations and Traits can further boost its income. You can stack different Traits to push its earnings even higher.
2. Cabin Bros – High-Income Alternative
$205M/s
Crafting Cost: $205B | Crafting Time: 60 minutes
Cabin Bros generates $205M/s, making it the second-highest-income Bros.
It requires Bearito Cabinito and Lionello Casarello, costs $205B to craft, and takes 60 minutes.
Although the investment is substantial, Cabin Bros is worth considering if you already have the required ingredients and want another high-income Bros.
3. Machine Bros – Best Balance Between Income and Cost
$145M/s
Crafting Cost: $65B | Crafting Time: 45 minutes
Machine Bros generates $145M/s, costs $65B to craft, and takes 45 minutes.
Its income is lower than Scary Bros and Cabin Bros, but its crafting cost is considerably lower. If you don't want to spend over $200B but still want a relatively high-income Brainrot, Machine Bros is a solid middle-ground option.
4. Tang Bros and Spinny Bros – Lower-Cost Choices
Tang Bros generates $82.5M/s, costs $15.4B to craft, and takes only 15 minutes.
Spinny Bros generates $61.5M/s and costs $15.1B, with the same crafting time.
The difference in crafting cost is only $300M, but Tang Bros generates an additional $21M/s. If you already have the required ingredients, I'd recommend Tang Bros over Spinny Bros when income is your priority.
5. Noobini Bros – Budget Option
$11M/s
Crafting Cost: $1.6B | Crafting Time: 5 minutes
Noobini Bros has the lowest base income at $11M/s, but it's also the cheapest and quickest Bros to craft.
It only requires $1.6B and takes 5 minutes to complete. If you want to try out the Bros Machine without spending too much cash, Noobini Bros is a good starting point.
My recommendation: Go for Scary Bros if you want the highest income, choose Machine Bros for a balance between income and cost, or consider Tang Bros and Noobini Bros if you're on a tighter budget. Don't focus on base income alone; whether you already own the required ingredients also matters.
Mutation Chances for Bros Brainrots
Besides base income, Mutations are another factor worth considering when choosing which Bros to craft. The following chances have been confirmed through in-game crafting screenshots.
| Bros Brainrot | Mutation | Chance |
|---|---|---|
| Scary Bros | Radioactive | 15% |
| Scary Bros | Lava | 15% |
| Machine Bros | Eclipse | 15% |
| Noobini Bros | Eclipse | 15% |
| Tang Bros | Galaxy | 15% |
| Nacho Bros | Divine | 15% |
Note: These Mutation options and chances have only been confirmed for the Bros listed above. Other Bros do not have confirmed options in the information currently available.
How Long Will the Bros Machine Stay?
According to Sammy's comments during an Admin Abuse session, the Bros Machine was initially expected to stay for around two weeks. A possible extension to three weeks was also discussed.
The Fuse Machine may also return during the Christmas period in December, but an exact date has not been confirmed.
The exact removal date of the Bros Machine has not been confirmed. If you're planning to craft a particular Bros, it's best to prepare the required ingredients in advance rather than waiting until the machine is about to disappear.
