What Is the Fuse Machine & Why It Matters?
The Fuse Machine is a game-changing feature introduced in Steal a Brainrot that allows players to sacrifice four Brainrots to create one new Brainrot from a pool of available options. Unlike the previous Bubblegum Machine system, the Fuse Machine offers strategic depth through rarity-based mechanics and probability tables.
Originally launched on August 1, 2025, the Fuse Machine was temporarily removed on September 6, 2025, but made a triumphant return on January 24, 2026, at 3 PM EST due to overwhelming player demand. This updated version brought back all the Common-Legendary Brainrots from the original machine while adding eight new Mythic-Secret tier Brainrots, including the highly sought-after Hydra Dragon Cannelloni.
The machine’s importance cannot be overstated – it’s one of the primary methods for obtaining the rarest Brainrots in the game, including Secret tier units that can generate millions of dollars per second in passive income.
How to Use the Fuse Machine: Step-by-Step Process
Step 1: Prepare Your Brainrots
Before approaching the Fuse Machine, you need to select which Brainrots you want to sacrifice. Hold the E key near any Brainrot in your base to pick it up. Consider the rarity and value of each Brainrot carefully, as they will be permanently lost during fusion.
Step 2: Locate the Fuse Machine
The Fuse Machine is strategically positioned in the central area of the map, right beside the Coins Shop. You can’t miss it – it’s the large, mysterious-looking machine with glowing fusion effects.
Step 3: Submit Your Brainrots
Walk up to the Collect Zone in front of the machine while carrying a Brainrot. The machine will automatically accept it. Repeat this process until you’ve submitted exactly four Brainrots. You can mix and match rarities as you see fit.
Step 4: Initiate the Fusion Process
Once you have four Brainrots in the machine, press the E key to open the Fusion interface. This menu will display:
- The four Brainrots you’ve submitted
- The required fusion cost (varies by rarity combination)
- The waiting time (15, 30, or 90 minutes)
- Possible reward rarities and their probabilities
Step 5: Confirm and Wait
Review the information carefully, then click the “Fuse Brainrots” button to begin the process. The cost will be deducted from your in-game currency, and the timer will start.
Step 6: Claim Your Reward
After the waiting period expires, return to the Fuse Machine and hold the E key to claim your new Brainrot. The machine will deliver one Brainrot from the available pool based on the probability calculations.
Optional: Skip the Wait
If you’re impatient or time-constrained, you can spend 290-299 Robux to skip the waiting time entirely and claim your Brainrot immediately. This is generally only recommended for high-value fusions where time is critical.
Understanding Fusion Mechanics & Rarity System
How Rarity Affects Outcomes?
The Fuse Machine uses a sophisticated rarity system that determines both your fusion costs and potential rewards. The system works on a 7-point scale:
- Common (1 point)
- Rare (2 points)
- Epic (3 points)
- Legendary (4 points)
- Mythic (5 points)
- Brainrot God (6 points)
- Secret (7 points)
The machine averages the rarity values of your four submitted Brainrots to determine your “Dominant Rarity” – the rarity tier you’re most likely to receive as a result.
The 10% Rule: Always a Chance for Better
One of the most important mechanics to understand is that you always have at least a 10% chance to receive a Brainrot one rarity tier higher than your Dominant Rarity. If you submit high-quality Brainrots within your chosen rarity tier, this chance can increase up to 50%.
For example, if your Dominant Rarity is Legendary, you have at least a 10% chance to get a Mythic Brainrot, potentially up to 50% if your submitted Legendary Brainrots are all high-value ones.
Generation Value Matters
Beyond just rarity, the money-per-second generation of your submitted Brainrots affects outcomes:
- For same-rarity results: Higher generation Brainrots increase chances of getting better Brainrots within that rarity
- For higher-rarity results: The machine typically gives the lowest-generation Brainrot of the higher tier
Trait Inheritance System
Your fused Brainrot has a 10-20% chance to inherit any traits or mutations from your submitted Brainrots. If multiple submitted Brainrots share the same trait or mutation, the inheritance chance increases up to 20% per specific trait/mutation.

Advanced Fusion Strategies & Pro Tips
Risk Management Strategies
Start Small, Build Up Don’t immediately jump into high-risk fusions with your most valuable Brainrots. Begin with lower-tier combinations to understand the mechanics and build your fusion experience.
Calculate Expected Value Before any fusion, calculate whether the potential rewards justify the cost. For example, fusing four Brainrot Gods might seem exciting, but you could lose significant value if you receive a lower-tier result.
Timing & Server Selection
Private Server Advantage If you have access to a private server, use it for all fusions. This prevents other players from stealing your newly created Brainrot while you’re waiting for the fusion to complete.
Server Population Strategy When using public servers, choose servers with players who have less money than you. This reduces the risk of someone buying your newly fused Brainrot before you can claim it.
Fusion Combinations by Goal
Best for Space Saving
Use unwanted or duplicate Brainrots for fusion. This accomplishes two goals:
- Clears valuable space in your base
- Prevents theft of unwanted Brainrots
- Potential for valuable returns
High-Risk, High-Reward Strategy
For players with substantial resources:
- 4 Brainrot Gods: ~46% Mythic, ~48% God, ~6% Secret
- 3 Secrets + 1 Brainrot God: ~25% Mythic, ~31% God, ~44% Secret
- 2 Secrets + 2 Brainrot Gods: ~45% Mythic, ~25% God, ~30% Secret
Conservative Progression
For steady advancement:
- 4 Legendary: ~14% Legendary, rest lower rarities
- Mix of Epic + Rare + Common: Predictable results with lower risk
Cost Analysis by Rarity Tier
| Highest Rarity Input | Wait Time | Typical Cost Range |
|---|---|---|
| Common/Rare/Epic | 15 minutes | $500 – $50,000 |
| Legendary/Mythic/Brainrot God | 30 minutes | $50,000 – $5,000,000 |
| Secret/OG | 90 minutes | $5,000,000+ |
Common Mistakes to Avoid
Don’t Mix Extreme Rarities
Avoid combinations like 3 Secret + 1 Common. The low-rarity Brainrot significantly reduces your chances of high-tier results and wastes valuable resources.
Don’t Fuse for Profit Early Game
Early in the game, focus on building your base income rather than risky fusions. The Fuse Machine becomes more valuable when you have excess resources and specific goals.
Don’t Ignore the Skip Option Wisely
While skipping the wait costs Robux, it can be worth it during limited-time events or when server conditions are dangerous. However, avoid skipping low-value fusions where the cost isn’t justified.
Don’t Forget About Events
Pay attention to special events and admin abuse sessions. Sometimes fusion odds are temporarily increased, making it the perfect time for high-value fusions.
Troubleshooting Common Issues
Fusion Not Starting
- Ensure you have exactly 4 Brainrots submitted
- Check that you have sufficient in-game currency
- Verify you’re not in a restricted area or during server maintenance
Can’t Claim Brainrot
- Wait for the full fusion timer to complete
- Make sure you’re in the correct collection zone
- Check if another player has already claimed it
Unexpected Results
- Remember that fusion involves probability and RNG
- Review the rarity chances shown before fusion
- Consider that generation values affect specific Brainrot outcomes
