All Steal An Egg Biomes: Speed Requirements, Guardians & Egg Pools

How many biomes are in Steal An Egg?

Twelve egg zones in total: ten main biomes that unlock in a fixed Speed order — Forest, Lake, Desert, Jungle, Snow, Volcano, Abyss Ocean, Prehistoric, Cosmic, and Cherry Blossom — plus two event zones, Titan Temple and Angels & Demons. Each biome has its own guardian, its own egg with an 8-pet pool, and an income ceiling roughly an order of magnitude above the zone before it.

Every biome and its Speed requirement

Community sources agree on the order and most thresholds; where they conflict we show the range:

How do guardians work?

Every biome has a guardian — the zone’s apex predator that aggros when you pick up an egg. Guardians scale with their biome’s Speed gate: a guardian built for a 700K-Speed zone trivially catches a 100K-Speed thief. There is no fighting them — your only counter is Speed, trails, and route discipline. Per-zone guardian details live on each biome page.

How do the event zones work?

Titan Temple and Angels & Demons sit outside the linear progression as event zones with their own eggs and pet pools. Angels & Demons is the headline — its Light and Dark egg pools each end in a $5B/s Divine (ArchAngel and World Burner), the joint-best hatchable pets in the game. Event availability rotates with updates; check the update tracker for what is live.

What is the right progression path?

Farm each biome’s eggs until its pets replace your weakest earners, then push Speed for the next gate — do not linger in a zone you have outgrown, and do not suicide-run a zone you cannot escape. The speed training guide covers how to hit each gate, and the pets index shows exactly which pets each zone’s egg can pay out.
