SOURCE-CHECKED DATABASE

Steal An Egg Mutations

Mutations are confirmed as part of the experience, but their current names, effects, and math need direct evidence. Until then, this database keeps the distinction between a mechanic and its formula clear.

Track a mutation without inventing its effect

Copy the mutation label exactly as it appears in your session and note the visible pet result before and after the change. Keep size, quantity, upgrades, and other inputs stable where possible.

A visual glow or unusual color can help you recognize a variant, but it is not enough to assign a name or multiplier. The public registry waits for a readable in-game label or another reliable first-party source.

Why the calculator stays in comparator mode

A calculator suggests a formula is known. Applying a guessed coefficient would produce precise-looking but unreliable answers. The tool therefore multiplies only the observed income you enter by a quantity you enter.

Mutation and size notes remain annotations. Once a complete rule is verified for the correct version of the correct game, the tool can graduate from safe comparison to calculation with a visible formula and date.
