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 space idle clicker; one planet reborn under your hands. Free and unblocked — 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).
- Reach the Ascendant Gate — grow your world all the way to its final stage to complete
Chapter 1 and ascend toward the next world.

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.
Is Planet Clicker unblocked at school or work?
The whole game is one self-contained web page — nothing to install, no login, no launcher. Wherever a browser works, the game works, and your save lives in that browser's local storage.
Is this a space clicker or an idle game?
Both. It plays like a classic space clicker — tap the planet, catch comets — but your structures keep producing on their own, idle-game style, even while the tab is closed (up to 8 hours are banked).
Can I play with my keyboard?
Yes — tap Space or Enter to channel Stardust instead of clicking. Handy on a laptop, and easier on your mouse hand during a Supernova.
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.
How do chapters work?
Each chapter is a self-contained world. To complete Chapter 1 you fill a checklist of goals (reach the final Earth stage and build up your key structures) and then win a final challenge — the Ascendant Burn, a timed ignition of the Gate — before you Ascend to the next world. There is no endless prestige loop or shard currency: you finish a world and move on.
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.
