What is confirmed about mutations?
The official Fake an Egg icon retrieved in this review contains an offline-mutation promotional claim. That is evidence of how the game is advertised, not a numerical specification of offline gains, mutation odds or stacking behavior.
The guide does not assign Golden, Rainbow, Radioactive or Void multipliers. The supplied video shows Rainbow, GOLD and DIAMOND labels, but does not establish their formulas. A planning prompt alone cannot establish additional variants. Fuse stages and their bonuses are also unverified.
How can you test an upgrade without mixing effects?
Record the pet's exact current label and displayed rate before changing it. Keep active boosts and other upgrades unchanged, then record the resulting label and rate. If several things change together, the comparison cannot isolate one mutation's effect.
For an offline observation, record the logout and return times, starting state and any displayed result. A single return does not establish a stable rate or a probability. Keep server changes and unknown events visible in your notes.
When should a multiplier go into the calculator?
Enter a multiplier only when you know what base rate it applies to. The default of 1 makes no extra multiplier assumption. A final rate already shown by the game should not be multiplied a second time.
If you are deciding whether to spend, compare the added cost with the improvement you observed. When the requirement or outcome is uncertain, preserve the uncertainty instead of converting it into a guaranteed payback estimate.

The exact experience's official promotional image shows eggs in nests and an avatar inside a cracked egg. It establishes visual identity only, not a controlled real-versus-fake test, animation timing or item stats.

Actual introductory gameplay frames reviewed on 2026-10-17 show Bunny Egg at 0:10, Bunny and RAINBOW Cat at 1:00, and Chicken Egg variants at 2:40.
