mySolar - Build your Planets

Start with a lonely speck of dust and grind it into a gas giant that swallows entire solar systems — how far can your gravity reach?

You start with nothing but a faint cluster of particles floating in the void. Each click adds mass, and before long that loose speck starts pulling in stray dust on its own. That's the hook: mySolar - Build your Planets turns mindless clicking into a strangely meditative loop of cosmic growth. You'll watch your little rock turn into a molten ball, then a planet with rings, then something that could swallow Jupiter without blinking. I kept coming back just to see how absurdly big one object could get. The real fun kicks in when you start placing orbits and nudging new bodies into the system. There's this moment when you fire a small moon too close to your main planet and physics takes over — it spirals in, speeds up, and smacks into the surface, adding its mass in a satisfying flash. You can also spend accumulated energy on upgrades that boost gravity, click power, and idle generation. It's not deep strategy, but it doesn't need to be. It's the digital equivalent of rolling a snowball down a hill and watching it pick up parked cars. I do wish the late game gave you more reasons to experiment with multiple systems side by side. Once you have a supermassive core, smaller planets feel like clutter. But the charm holds: the sound effects are soft and blippy, and the color shifts as your planets heat up are genuinely pretty. If you want a clicker that feels more like a toy than a spreadsheet, this one scratches that itch without demanding your full brain.

Mouse and Keyboard

Smash early upgrades into click power first — idle generation matters less until you have a few planets already stable. Don't merge every planet you make. Keeping three or four mid-sized bodies gives you more places to dump mass when you need a big boost. Watch the velocity vector before you fling a new moon into orbit. A little extra speed turns a satellite into a cannonball. Spend energy on gravity radius upgrades as soon as they unlock; passive pull becomes your main source of mass later. If you're grinding for a new planet size, park the game in a background tab for ten minutes and spend the idle gains all at once. Use the keyboard to zoom out and admire your whole system — then click the smallest asteroid you see to remind yourself where it started.
