Biomes
Steal An Egg biomes — speed-gated zones, where rare eggs spawn, and the best biomes to raid for pets and money.
Introduction
The Biomes hub maps the zones of Steal An Egg and how you unlock them. Every player starts in the first biome, and as you train your treadmill and raise your Speed stat, you unlock new biomes — each one holding better eggs, pets and income than the last. The community reports that Speed milestones gate biome access, though the exact thresholds are not officially published. Because each biome holds better eggs and pets, knowing what each zone offers and what to raid when is a core part of progression. This hub covers the biome progression ladder, the Speed requirements, and the best strategies for raiding each zone efficiently.
Biome Progression
| First Biome | Starting zone | Learning the loop | Starter eggs |
|---|---|---|---|
| Desert Biome | Speed tier 1 | Early nest eggs | Nest raids |
| Snow Biome | Speed tier 2 | Rare eggs, better pets | Rare spawns |
| Ocean Biome | Speed tier 3 | Legendary eggs | Big raids |
| Endgame Biome | Max Speed | Best eggs and income | Endgame |
Biome Guide
First Biome
Where every player starts stealing eggs. The first biome is deliberately low-stakes — mostly wandering pets, small nests and starter eggs — so it is the perfect place to learn the loop before you risk contested steals. Revisit this page whenever you unlock a new zone so you always know what to raid next.
Desert Biome
The first Speed-gated zone, unlocked at the earliest Speed milestone. The desert holds more nest eggs and early pets than the starting zone, making it the first real upgrade in your stealing territory. Raid it early for steady nest eggs before you push your Speed higher.
Snow Biome
A higher Speed-gated zone where the community reports rarer egg spawns and better income pets. The snow biome is where your collection starts to matter, with rare eggs worth contesting. Contesting its rare spawns is a reliable step toward a stronger collection.
Ocean Biome
A deep Speed-gated zone with legendary eggs and high-value pets. The ocean biome is a serious upgrade in both risk and reward, and the rare-egg race spawns here can be fiercely contested. Bring a fast carrier and a lookout, because the prizes here are worth the fight.
Endgame Biome
The final zone at max Speed, holding the best eggs, pets and income in the game. Reaching the endgame biome is the long-term goal of the treadmill ladder, and it is where the strongest collections are built. Most of your long-term progression goals live here, so plan your treadmill training around it.
Core Mechanics
Biomes in Steal An Egg are unlocked by Speed, which you raise by training on your treadmill. The community reports that hitting Speed milestones opens the next biome, with each zone holding progressively better eggs, pets and income. The first biome is where you learn the steal-and-hatch loop, and each subsequent biome raises the stakes: better nests, rarer eggs, and more valuable pets, but also more competition. The specific biome names and their exact Speed requirements are community-reported estimates — the game is young and the zones are still being mapped by players. Because higher biomes hold better eggs, reaching them is the primary driver of late-game progression, which makes treadmill training and biome unlocking two sides of the same loop.
Advantages
A clear biome map tells you exactly where to spend your stealing effort. Most players stay in the first biome far too long, missing the better eggs and pets that higher zones offer. Knowing the Speed milestones that gate each biome lets you set concrete training goals and reach the better content faster. The zone-by-zone breakdown also helps you plan raids — knowing that the snow biome holds rare eggs or that the endgame biome has the best income tells you what to target when you get there. And because biomes are gated by Speed, the biome guide doubles as an upgrade guide, tying your treadmill priorities directly to the content you want to unlock.
Challenges
Biome data is among the least certain content in Steal An Egg because the zones are young and community-mapped. The exact biome names, their order, and the Speed thresholds that gate them are community-reported estimates, not official data, and they can shift with updates. It is possible the game uses different names or a different unlock system than the community currently describes. The specific eggs and pets in each zone are also only partially documented. Players should treat the biome ladder here as a working model, watch for unlock prompts as their Speed rises, and expect the map to change as the game adds or rebalances zones.

Quick Tips
Always train toward the next Speed milestone. Every biome you unlock raises the quality of eggs, pets and income, so consistent treadmill training is the single most reliable way to improve everything in your game. The habit pays off most when you are close to the next milestone, so keep training even during short sessions.
Raid the highest biome you can handle, not the highest one unlocked. A contested egg in a biome above your ability is worse than a clean steal in the zone you know, so farm your current zone until the next one is comfortable. It keeps your farming efficient and your progression moving even when you have limited time.
Track which biomes hold the eggs you want. If you are chasing legendary or mythic eggs, prioritize the Speed milestones that unlock the zones reported to hold them, and focus your stealing there. Combined with a strong income roster, it turns small sessions into steady biome progress. Combined with a strong income roster, it turns small sessions into steady biome progress.
