How to Use the Fuse Machine in Steal an Egg

How to Use the Fuse Machine in Steal an Egg

Steal an Egg drops players into animal pens scattered across the map, where the goal is to grab an egg, escape the guarding animal, and carry that egg back to a personal base for hatching. Every hatch adds a pet to the collection, and repeat hatches eventually pile up duplicate pets that sit in the yard doing very little for total income. The Fuse Machine exists to solve that exact problem, turning three matching pets into one stronger earner.

Not every duplicate deserves a trip to the machine, since some spare pets already earn more sitting in place than any fused result would. The sections below cover requirements, the fusing steps, and when a fuse actually pays off.


Using Fuse Machine in Steal an Egg Summary

Using Fuse Machine in Steal an Egg Summary
  • Fuse Machine lets you combine three copies of the same pet into one upgraded pet, but you can’t mix different pets.

  • The machine sits at the player's base, near the pen and treadmill, with no cooldown or unlock requirement

  • Using the machine costs nothing beyond the three pets themselves, and no premium purchase is needed

  • A fused pet earns money per second equal to or higher than the three pets that went into it

  • Fusing carries a chance to produce a mutated pet, which pays out several times more than a standard result

  • Mutated pets used as inputs do not pass their mutation to the fused result, so feeding the machine a mutated pet risks losing that mutation for good

  • Fusing works best on low-income duplicates, while top earners generally do more good staying placed in the base


What is the Fuse Machine in Steal an Egg

Fuse Machine is a base feature built specifically to clear out duplicate pets while turning them into something more useful. Instead of letting three copies of the same creature sit around earning three small amounts of cash, the machine consumes all three and replaces them with a single pet that earns as much or more.

The machine is placed at the player's base, close to the pen and the treadmill, which keeps it within easy reach during normal gameplay. There is no separate unlock step and no waiting period tied to account progress, so the machine becomes available the moment a player has three matching pets in hand.


Requirements to Use the Fuse Machine

Before attempting a fuse, a few conditions need to line up. The machine is strict about what it accepts, and understanding those limits early prevents wasted trips back to the base.

Here is what the Fuse Machine requires before it lets a merge happen:

Requirement

Detail

Input count

Three pets total

Matching rule

All three must be the exact same pet

Mixing pets

Not permitted under any combination

Location

Fuse Machine at the player's base

Cost

Free, no premium currency required

Cooldown

None, usable at any time

Collecting three identical pets is not a common occurrence during the early stretch of the game, since new zones tend to introduce fresh species faster than duplicates build up. Fusing becomes a realistic option once a player has spent enough time hatching eggs to accumulate repeat pets from the same species.

Rarer pets used as inputs shift the odds toward a stronger output, so saving matching sets of higher-tier pets instead of fusing the very first duplicate found tends to produce better long-term results. Weighing rarity against how badly the base needs the fuse slot cleared is the main decision to make at this stage.


Step by Step: How to Fuse Pets

Fusing pets in Fuse Machine

Once three matching pets are in hand, the actual fusing process takes only a few actions. The steps stay identical no matter which pet species is involved.

These are the steps that turn three duplicate pets into one fused result.

  1. Pick up the three matching pets from the base so all three are being carried at once

  2. Walk over to the Fuse Machine and place each pet into the open slots provided

  3. Press the Fuse button to start the merge

  4. Collect the new pet once the three inputs disappear and a single upgraded pet appears in their place

Placing a pet into the wrong slot is not something to worry about, since the machine only accepts matching pets and will simply reject anything that does not fit the set. The whole process finishes almost instantly, with no waiting screen or timer standing between submission and the finished pet.

Comparing the new pet's money-per-second value against the three originals right away confirms whether the fuse improved total income or simply consolidated it. That quick check also helps build a sense of which species tend to produce stronger fused results over repeated attempts.

What a Fused Pet Turns Out To Be

The pet that comes out of the machine is never weaker than the three that went in. At minimum, the result matches the combined earning potential of the originals, and in many cases it comes out ahead. There is also a chance the fusion produces a mutated pet, which generates several times more income than a standard version of the same species.

That roll is not guaranteed on any single attempt, and higher rarity inputs appear to improve the odds without locking in a guaranteed mutation. One detail catches new players off guard here: a mutated pet fed into the machine as an input does not carry its mutation forward into the result, so the safest inputs are plain, unmutated duplicates rather than anything with a special roll already attached.


When Fusing Pays Off and When To Skip It

Pet Created from fusion

Fusing is a one-way trade, since the three input pets are destroyed the moment the new pet appears. That makes the decision of what to fuse worth thinking through before committing anything valuable.

The table below breaks down common situations and when fusing makes sense in each one:

Situation

Fuse?

Three copies of a weak, low-income pet

Yes, clears clutter and creates one stronger earner

Three copies that rank among the base's top earners

No, leaving them placed usually earns more overall

Any pet that carries a mutation

No, the mutation does not transfer to the result

Three mid-tier pets with no current use

Yes, especially once base space is running low

Checking total money-per-second before and after a planned fuse takes only a moment and prevents an accidental drop in income. A base that is short on space benefits the most from regular fusing, since clearing low earners frees up room for stronger pets found later.

Holding onto strong duplicates instead of rushing them into the machine is rarely a mistake, since those pets keep earning at full strength as long as they stay placed. Fusing works best as routine maintenance for the bottom half of a collection, not as the default move for every duplicate that shows up.


Common Mistakes With the Fuse Machine

A handful of habits quietly cost players income over time, and most of them come down to fusing without checking the numbers first. Slowing down before pressing the Fuse button avoids nearly all of them.

Feeding mutated pets into the machine is the single most common error, since the mutation disappears from the final result and cannot be recovered afterward. Fusing a set of pets that were already outperforming everything else in the base is the second most frequent mistake, since the resulting pet rarely beats three strong earners left in place. Comparing income totals before committing to a fuse solves both problems in a matter of seconds.


FAQs About the Fuse Machine in Steal an Egg

FAQs About Using Fuse Machine in Steal an Egg

How many pets does the Fuse Machine need?

Three copies of the exact same pet are required for every fusion, and the machine will not accept a mix of different species. All three are consumed once the fuse completes.

Can mutated pets be fused?

Mutated pets can be placed into the machine, but the mutation does not carry over to the fused result. Feeding a mutated pet into the machine risks losing that mutation permanently in exchange for a plain output.

Does the Fuse Machine cost anything to use?

The Fuse Machine is completely free, with no premium currency or in-game cash required. The only cost is the three pets used as inputs.

Is there a cooldown on the Fuse Machine?

There is no cooldown or waiting period attached to the machine. It can be used repeatedly, back to back, as long as three matching pets are available each time.

Does fusing always produce a better pet?

The fused result earns money per second equal to or higher than the three original pets, so a fuse never technically produces a weaker earner. It can, however, still fall short of what three strong pets would have earned if left placed instead of fused.


Final Words

The Fuse Machine turns a cluttered base into a more efficient one, but only when the pets going into it are the right ones to lose. A quick income check before every fuse keeps a collection strong instead of accidentally trading away pets that were already carrying the base.

Treated as routine cleanup for weak duplicates rather than a shortcut for every spare pet, the Fuse Machine becomes one of the steadier ways to raise total income without hatching a single new egg.
