Ultimate Guide on How to Fuse Brainrots: Best Combos, Odds, etc3 min read

Linking many Brainrots to create rarer, more expensive ones is a strong new mechanism brought by the Steal a Brainrot Fuse Machine update, often referred to in guides as the “witch fuse” idea.

This guide explains how it operates, your chances, and strategies to increase your earnings.

What Is the Fuse Machine & Why It Matters

In Steal a Brainrot, the Fuse Machine can be found in the lobby or central area, next to the Coins Shop. This gadget lets you submit up to four Brainrots and mix them into a single higher-tier unit, in contrast to earlier mechanics (such as the Bubblegum Machine).

You lose your submitted Brainrots forever when you fuse. Your submission’s rarity will decide the final Brainrot. Higher-tier combinations are more expensive, take longer, and are more likely to result in secret or rare outcomes.

How to Use the Fuse Machine: Step by Step

1. By holding down “E” (or the corresponding action key), you can take up a Brainrot from your base.
2. Go to the Collect Zone of the Fuse Machine and turn it in. Repeat until you’ve turned in four units.
3. Press “E” to connect with the system and launch the Fusion user interface. It will display the waiting time, the necessary cost, and the potential following rarities.
4. By buying Robux (often around 299 Robux), you can avoid the wait if you’d like.
5. Go again to the machine and get your new Brainrot when the timer goes off (or you skip it).

Top-tier combinations may take a full 90 minutes or longer to process, while common combinations may take 15 minutes. Wait durations differ based on the rarity of the submitted combination. Furthermore, the cash cost increases with rarity.

Rarity Odds & Useful Combos

Probability tables are used in the fusion system; some combinations boost the likelihood of Secret or Mythic events. Here are a few examples of combos:

• 2 Brainrot Gods fused: ~45% chance for Mythic, ~25% chance for Brainrot God, ~30% Secret.
• 3 Secrets + 1 Brainrot God: ~25% Mythic, ~31% God, ~44% Secret. 
• 4 Legendary: ~14% chance of Legendary output, rest lower rarities.
• 4 Brainrot Gods: ~46% Mythic, ~48% God, ~6% Secret.

These are but a few examples; before finalizing your fusion, always look at the chances displayed by the user interface. Dream of owning Nuclearo Dinossauro? Check out the sneaky steal method and how to unlock this secret beast.

Tips for Maximizing Your Fuse Results

• Cost and risk must be managed; don’t always go for early, secret results. As you gain resources, use safer combos.
• Wait for bonus events: At times fusion odds are increased by events or buffs; fuse when these occur.
• Create a plan for your rarities: Put in a super-rare unit only if you think the expected return is greater than the danger.

Don’t skip the Brainrot-buying playbook – it’s a smart companion to any event or fusion guide.

• Make full use of the skip option: If you’re short on time, it can be beneficial to pay Robux to skip, but stay clear from low-tier fusions.
• Experiment and monitor: As time passes, note which combinations worked best for your style of play.
