Frequently Asked Questions
How do egg hatch chances work?
Each pet has a fixed hatch chance when opening its associated egg. For example, a 5% hatch chance means you have a 1 in 20 chance per egg. Opening more eggs increases your odds but never guarantees a specific pet.
How many eggs do I need to hatch a specific pet?
The expected number of eggs needed is 1 divided by the hatch chance. For a 1% chance pet, you need about 100 eggs on average. For a 30% chance pet, only about 3-4 eggs.
Which egg source has the best pets?
Fantasy Eggs and Strawberry Eggs contain epic and legendary pets with high multipliers. Basic Eggs have common pets with lower bonuses. 67 Packs contain the legendary 67 pet with a massive 50x muscle bonus.
