TLDR:
- Break and Steal an Egg currently has 8 confirmed Mutations: Gold, Diamond, Lightning, Frozen, Angelic, Hacker, Time and Void.
- Gold (1.5x) and Diamond (2x) come from randomly hatching eggs, while the other six are tied to weather or special events.
- Void is the best Mutation at 5x earnings, and it only appears during the Void Event.
- Mutation boosts are listed as multipliers on Cash earned, so a mutated pet in your base earns far more than its base version.
In Break and Steal an Egg, you break eggs, grab the animal that hatches, escape the guards and bring it back to your base to earn Cash. Mutated pets are one of the best ways to boost that income, since a mutation multiplies what a pet earns. Getting them mostly depends on being online during the right events. This guide covers every Mutation we know of, how much each one multiplies, and how to get it.

There are currently 8 Mutations. Two come from hatching eggs and the other six come from weather or special events.

How To Get Hatch Mutations in Break and Steal an Egg?
Gold and Diamond are Hatch Mutations. They can appear when you open an egg, so there is nothing special to do except keep breaking eggs and carrying the animals home.
To improve your odds, break as many eggs as you can. A faster pickaxe means more eggs in less time. Each zone has pickaxes recommended for it, such as the Stone Pickaxe for the Forest and the Golden Pickaxe for the Desert.
TIP: Higher zones also have more valuable pets, so a Gold or Diamond mutation there is worth much more Cash. Stronger pets multiplied with a mutation is what you should try to get.
What Is the Best Mutation in Break and Steal an Egg?
Void is the best at 5x, followed by Time at 4x and Hacker at 3.5x. In practice, the best mutation is usually the highest multiplier on your highest-earning pet. For example, a 2x Diamond on a Celestial pet like Amphiptere ($125M/s) will outperform a 5x Void on a Common one, so focus on pet quality as well as mutation.
