How to Use Fuse Machine: Complete Step-by-Step Process
Step 1: Gather Your Brainrots
Before you can start fusing, you need to collect Brainrots from your base. Here’s how to do it efficiently:
- Go to your base and locate the Brainrots you want to fuse
- Hold down the E key (or tap on mobile) to pick up a Brainrot
- Carry it to the Fuse Machine – you’ll see a glowing “Collect Zone”
- Stand in the Collect Zone to deposit your first Brainrot
- Repeat this process until you’ve submitted exactly 4 Brainrots
Pro Tip: Always plan your combinations in advance! Once you submit Brainrots to the Fuse Machine, they’re gone forever – there’s no undo button.
Step 2: Configure Your Fusion
Once you have 4 Brainrots in the machine, it’s time to set up your fusion:
- Press E to interact with the Fuse Machine interface
- Review the fusion details – you’ll see:
- Total cost in in-game currency
- Waiting time based on your rarest Brainrot
- Probability breakdown for each possible rarity outcome
- Confirm the fusion if you’re satisfied with the terms
- Pay the required amount to start the fusion process
Step 3: Wait or Skip the Timer
The fusion time depends entirely on your rarest submitted Brainrot:
| Rarest Brainrot | Fuse Time | Cost Range |
|---|---|---|
| Common/Rare/Epic | 15 minutes | $500 – $5,000 |
| Legendary/Mythic/Brainrot God | 30 minutes | $5,000 – $50,000 |
| Secret/OG | 1.5 hours | $50,000 – $500,000+ |
Skip Option: If you’re impatient (like I often am!), you can pay 299 Robux to skip the waiting time entirely. I only recommend this for high-value fusions where time is critical.
Step 4: Claim Your New Brainrot
Once the fusion completes:
- Return to the Fuse Machine when the timer finishes
- Hold E to claim your new Brainrot
- Check your base to see your new character
- Review the results – did you get the rarity you wanted?
Important: The new Brainrot will automatically appear in your base. Make sure to check its income rate and rarity to evaluate if the fusion was worth it!

Historical Note: 2025 Brainrots
The Fuse Machine originally launched in August 2025 with 15 Brainrots, then was removed in September 2025. When it returned in January 2026, it brought back the Common-Legendary brainrots but added 8 new Mythic-Secret characters, including the incredible Hydra Dragon Cannelloni!
Advanced Fusion Strategies & Probability Mechanics
Understanding the Rarity System
The Fuse Machine uses a sophisticated probability system that averages your input rarities:
Rarity Values:
- Common = 1 point
- Rare = 2 points
- Epic = 3 points
- Legendary = 4 points
- Mythic = 5 points
- Brainrot God = 6 points
- Secret = 7 points
The machine calculates your Dominant Rarity by averaging your 4 inputs and rounding to determine your most likely outcome. However, you always have at least a 10% chance to get one rarity higher than your Dominant Rarity!
Best Fusion Combinations by Goal
For Maximum Profit:
4 Legendary Brainrots
→ 58% Rare, 28% Epic, 14% Legendary
For High-Rarity Results:
2 Secret + 2 Brainrot God
→ 45% Mythic, 25% Brainrot God, 30% Secret
For Secret Hunting:
3 Secret + 1 Brainrot God
→ 25% Mythic, 31% Brainrot God, 44% Secret
Safe Mythic Attempts:
4 Brainrot God
→ 46% Mythic, 48% Brainrot God, 6% Secret
Pro Strategies I’ve Learned
- Save Space Strategy: Use unwanted Brainrots for fusions to prevent them from being stolen and save base space
- Private Server Advantage: Always fuse in private servers if possible – no competition for your results
- Event Timing: Wait for special events when fusion odds are boosted
- Generation Matters: Higher-income Brainrots of the same rarity increase your chances for better results
- Trait Inheritance: 10-20% chance to inherit traits from input Brainrots (up to 20% if multiple inputs share traits)
Secret Combinations & Hidden Features
Ketupat Bros Secret Recipe
This is the most valuable secret combination I’ve discovered:
Required Inputs:
- 1 Ginger Gerat
- 1 Ketupat Kepat
- Any 2 Secret Brainrots
Result: 50%+ chance for Ketupat Bros ($65B value, $145M/s income!)
Lucky Block Exploit
Warning: This is a bug that may get patched!
You can actually put Lucky Blocks into the Fuse Machine. While this isn’t intended gameplay, some players have reported interesting results. Use at your own risk!
Special Time-Based Combinations
During the first two weeks of the original Fuse Machine launch, you could fuse 4 Mythic Brainrots with zero chance to get a Mythic result. This was patched, but it shows how the developers can adjust mechanics over time.
Common Mistakes to Avoid
Mistake #1: Mixing High and Low Rarities
Never submit 3 high-rarity Brainrots with 1 low-rarity Brainrot! This drags down your average and significantly reduces your chances of good results.
Example: 3 Secret + 1 Common = Much worse than 4 Secret or 3 Secret + 1 Rare
Mistake #2: Fusing High-Value Brainrots Carelessly
I’ve seen so many players lose millions by fusing their best Brainrots without understanding the probabilities. Always calculate if the expected value is worth the risk!
Rule of Thumb: Don’t fuse Brainrots worth more than 10x the fusion cost unless you’re specifically targeting a higher rarity.
Mistake #3: Ignoring Generation Values
Two Brainrots of the same rarity can have vastly different income rates. Higher-generation Brainrots give you better odds for premium results within that rarity tier.
Mistake #4: Not Using Private Servers
If you have access to private servers, always use them for fusions! Public servers mean other players can potentially steal your newly-created Brainrots before you can claim them.
Platform-Specific Tips
PC Players
- Use keyboard shortcuts (E key) for faster interactions
- Keep probability calculators handy for complex combinations
- Consider using macros for repetitive fusion processes
Mobile Players
- Be extra careful with touch controls – it’s easy to accidentally submit wrong Brainrots
- Use the early reveal option (299 Robux) more often since mobile play is often on-the-go
- Consider playing on larger tablets for better visibility of the Fuse Machine interface
Console Players
- Take advantage of the precision of controller sticks for accurate Brainrot selection
- Use the pause menu to review fusion combinations before committing
- Consider using a USB keyboard for faster text input if needed
Troubleshooting Common Issues
Fusion Not Starting?
- Check that you have exactly 4 Brainrots submitted
- Verify you have enough in-game currency
- Make sure you’re not in a restricted area or during server maintenance
Didn’t Get Expected Rarity?
- Remember that fusion involves RNG (Random Number Generation)
- Check your combination against the probability tables
- Consider if your input Brainrots had the right generation values
Can’t Find Your New Brainrot?
- Check your base thoroughly – it may be in a different spot
- Wait a few minutes for server synchronization
- Contact support if the Brainrot doesn’t appear after 10 minutes
Frequently Asked Questions
How much does the Fuse Machine cost to use?
The cost varies based on your submitted Brainrots, starting from $500 for basic combinations up to $500,000+ for Secret-level fusions. The exact cost is shown before you confirm the fusion.
Can I get my Brainrots back after fusing?
No! Once you submit Brainrots to the Fuse Machine, they are permanently consumed. Always double-check your combinations before confirming.
What’s the fastest way to get Secret Brainrots?
The best strategy is using 3 Secret + 1 Brainrot God combinations, which gives you a 44% chance for Secret results. The Ketupat Bros secret recipe (1 Ginger Gerat + 1 Ketupat Kepat + 2 Secrets) gives you 50%+ chance for this valuable Secret.
Is the 299 Robux skip worth it?
I only recommend paying 299 Robux to skip for high-value fusions (Legendary+) or when time is critical. For basic fusions, it’s usually not worth the cost.
Can I fuse the same Brainrot multiple times?
Yes! You can submit duplicate Brainrots, though mixing different types often gives better results due to the averaging system.
What happened to the original Fuse Machine?
The original Fuse Machine was removed in September 2025 and replaced by the Craft Machine. Due to popular demand, it returned in January 2026 with both old and new Brainrots.
How do I maximize my fusion success rate?
Focus on using high-generation Brainrots, stick to proven combinations, fuse during special events, and always use private servers when available.
Can I get banned for using the Lucky Block exploit?
While not officially confirmed, using exploits like the Lucky Block bug carries some risk. I recommend avoiding it or using it sparingly.
