Idle · Explore · Evolve
Tap a tiny cell into a galaxy-spanning explorer — and watch your discoveries pile up even while you sleep.
You begin as one tiny living cell, drifting across the surface of Earth — discovering the world one impossibly small patch at a time.
Then you grow. And keep growing — into something far greater than you could imagine.
What you're in for
Map every corner of Earth across 10 wild biomes — then leave the planet entirely. Each world hides secrets you'll have to discover for yourself.
Begin as a microscopic speck barely aware of the world. Every prestige makes you visibly faster, bigger, and more astonishing — until you outgrow planets themselves.
Hire a crew to automate your exploration so it never stops — online or offline, with no time cap. Close the app, live your life, return to a fortune.
Dozens of activities, hundreds of upgrades, a full crew of managers, and prestige boosts that carry you further every single run.
Tap the fungal internet. Recruit squirrel spies. Clone a mammoth to trigger an ice age. Pull the plug on the Pacific. Every activity is a laugh-out-loud surprise.
Gorgeous animated visuals and a vibrant, ever-shifting world. One-tap simple to start, deep enough to play for months.
The journey
You start microscopic, slow, barely aware of the world around you. Every prestige evolves you — visibly faster, bigger, more astonishing — through form after form, until you outgrow the planet itself. Where you end up is part of the discovery.
Many more forms wait between a speck and the stars — discover them yourself.
Progress while you sleep
Hire managers to run every activity automatically — they keep discovering whether the app is open or not.
Away for an hour or a week, you earn the whole time. Close the app, live your life, return to massive earnings.
Watch one quick rewarded ad to double your offline haul and rocket ahead.
The solar system
Each planet is its own adventure with a surface, a strange underground, and a mechanic all its own — low gravity, raging storms, shifting day and night, and forces stranger still.
