Progress in this order: hatch, earn, train, then push the next biome
Start here when you need the order of systems, then move to a guide page when the decision becomes route-specific.
For Steal an Egg progression, the useful order is eggs, pets, income, treadmill Speed, biome test, and safer return. Public guide pages support the player vocabulary around Speed, biomes, offline hatching, trails, and pet income, but exact thresholds should stay source-labelled and checked against the live server.
