About the game

Cosmo Crumble is a cartoon space sandbox where you pick a planet, pick a space toy and crumble it into stardust. Every hit digs a real crater: the surface peels away, the mantle shows through, deeper hits reach the glowing core and finally punch right through. Cracks spread, the Crumble meter fills, and the whole planet breaks into chunks that tumble through space while moons wobble off their orbits and satellites go spinning away.

Smash eight made-up planets, from blue Pebblo and frosty Glacia to sweet Candora, ringed Ringaroo, crystal Geodia and the lava world Magmaw, with ten space toys: meteors, the Zap Beam, ice comets, meteor showers, a squad of friendly saucers, the Star Slicer, giant asteroids, the hungry Gulp Hole, the Bonk Ball and the Nova Seed. Every planet has three challenges, like splitting it in two or crumbling it in a few shots, and the stars you earn unlock new planets and new toys. Collect twelve trophies along the way.

How to play

Pick a planet, then a space toy from the bar at the bottom (keys 1–0).
Tap or click where you want to hit: meteors, comets and asteroids land exactly there. Hold to keep dropping meteors.
Zap Beam: hold and drag. Star Slicer: swipe across the planet. Bonk Ball: pull back, aim and let go.
Fill the Crumble meter to break the planet into chunks, then smash the flying chunks into dust.
Complete the 3 challenges of each planet to earn stars and unlock new planets and toys.
Keyboard: 1–0 choose a toy, Space fires, R rebuilds the planet, P or Esc pauses.

Tips and tricks

Watch the Crumble meter under the planet name. Strong hits like comets and asteroids fill it faster than small meteors, and a full meter breaks the planet apart.
Hit the same spot again and again to dig deeper: you go from the crust to the orange mantle, then the glowing core, and at the end the hole goes right through.
For the few-shots challenges, use the big toys. One Giant Asteroid fills a big part of the meter, and a Nova Seed planted near the middle of a planet hits hardest.
The Bonk Ball is strongest when it flies fast and straight at the centre. Pull back far and aim at the middle; a glancing hit does much less.
Blasts push moons and satellites away. A free moon falls towards the planet and crashes into it, which is how you crash a moon into Magmaw.
After a planet crumbles, keep playing: tap the flying chunks. Comets and bigger toys turn a chunk straight into dust, meteors break big chunks into smaller ones.
Place a Gulp Hole close to a moon to swallow it, or right on the planet to eat it from the inside.

Frequently asked questions

Is Cosmo Crumble free?

Yes. It is free to play in your browser on computer, tablet and phone, with no download and no account.

How do I unlock new planets and space toys?

Every planet has three challenges. Each one you complete gives a star, and new planets and toys open when you reach the number of stars shown on them. There are 24 stars in total.

How do I split a planet in two?

Choose the Star Slicer and swipe across the planet so the line passes close to its middle. A cut near the edge only slices a piece off.

Can I play again after a planet crumbles?

Yes. Keep smashing the chunks, or press Rebuild to get the planet back whole and try another challenge.

Is my progress saved?

Yes. Stars, unlocked planets and toys, trophies and records are saved automatically in your browser on that device.
