Planet Clicker

Think clicking is mindless? Try turning a speck of dust into a solar system without destroying your mouse.

Planet Clicker has you hammering a single button to grow a planet from asteroid to star. It's dumb in the best way. The first few minutes are pure dopamine: each click adds mass, the planet wobbles, and suddenly you've unlocked a moon. Then you realize the real game is deciding when to spend your accumulated mass on upgrades or save for the next celestial tier. I spent twenty minutes trying to hit a perfect Mercury size before giving up and buying a second planet just to see what would happen. There's no fail state. You can't lose. So the tension comes from how much you're willing to grind. Do you click fast enough to outpace the idle generation? Or do you close the tab, let it run for an hour, and come back to a solar system? The numbers inflate gloriously—trillions become quadrillions—and the screen slowly fills with orbiting junk. It's the kind of game you open 'for five minutes' and realize you've been staring at a circle for half a day. The controls are just mouse clicks, no keyboard shortcuts, no drag-and-drop. Click planet, watch mass go up, spend on upgrades. That's it. But there's a weird satisfaction in watching a pixelated dot turn into a recognizable Earth-like sphere, then into a ringed giant, then into a ball of pure flaming gas. If you've ever enjoyed Cookie Clicker or any idle game, this is the stripped-down cousin. If you haven't, this won't convert you.

Controls • Use mouse to play

Buy the first idle upgrade as soon as possible—it pays for itself while you read this. Don't bother clicking manually after the third planet; let the auto-generation carry you. Watch the upgrade costs: sometimes saving for a big tier jump beats buying five small ones. Your finger will hate you, so take breaks or bind a spare mouse button for rapid clicks. The planet's visual changes at certain mass thresholds—hit exact values for a tiny thrill.
