A dead world drifts in the dark. Channel its Stardust and watch it wake — molten crust, the first oceans, green life, city-light, a star-gate. One quiet idle clicker; one planet reborn under your hands. No download, no sign-up.
About this planet clicker
PlanetIdle is a free idle clicker game you play right in your browser. Channel Stardust
to wake a dead rock into a living planet, then build cosmic structures — meteor collectors, ocean
seeders, lunar mines, orbital rings, all the way up to a star-gate — that keep producing on their
own, even while you are away.
It is a classic incremental / idle game, but the planet itself is your progress bar: it
visibly grows from a barren core to molten crust, blue oceans, green life, a glowing civilization,
and finally an ascendant world ready to leap to the next. No download, no sign-up — your progress
saves automatically to your own browser.
How to play
- Channel the planet to draw Stardust by hand. Early on, every tap counts.
- Build cosmic structures on the right. Each one produces Stardust per second, forever.
- Buy upgrades to multiply your channeling, boost buildings, and link them with synergies.
- Come back later — your world keeps orbiting offline (up to 8 hours of progress).
- Make a Galactic Leap once you have grown enough: collapse the planet into a singularity
for permanent Starcore Shards that empower every world that follows.

Frequently asked questions
Is Planet Clicker free?
Yes. It runs entirely in your browser with no download and no sign-up. Your progress saves automatically to your device.
How do I save my progress?
Progress saves automatically to your browser's local storage every few seconds and when you leave the page. Clearing your browser data will reset it.
What is a Galactic Leap (prestige)?
Once you have grown your world enough you can leap — collapse it into a singularity in exchange for Starcore Shards that permanently boost all future production. The boost has diminishing returns (it scales with the square root of your total Shards), so your first Shard alone adds about +40%.
What is the comet?
Every minute or two a comet streaks across the screen for about 13 seconds. Tap it for a random reward: a lump of bonus Stardust (Windfall), or a 15-second ×7 production Supernova.
Does it keep producing when I'm away?
Yes. Your world banks up to 8 hours of offline Stardust, and you get a "welcome back" summary the next time you open the game.
