About this game

Smash worlds together and watch them shatter, merge, and melt — driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same.

Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust.

⦁ True particle physics (SPH) — the first of its kind on mobile
⦁ Molten impact zones: heat, lava, and cooling crusts
⦁ Give planets rings — or shred a moon into one with tidal forces (Roche limit)
⦁ Protoplanetary disk and colliding-galaxies modes
⦁ Black holes that tear planets apart
⦁ Custom planet textures from your own photos
⦁ Runs on everything: tune particle count, accuracy, and timescale to your device

Ratings and reviews

AWESOME game! the people in the reviews who say "OMG ITS SO LAGGY!" dont realize that you can just lower the particle count to be near 2000. also big thanks for adding my suggestion that said "make it so that you can type out the particle count and ui" also has GREAT realism! I think it does need optimization and definitely better lava though. overall this is awesome.

It's pretty a really good game, it doesn't lag, but can handle 10k particles without crashing my phone. I use the compute button, and yes the update is very good, but BRO, whenever I compute a high particle Collision, it just cuts off in the middle of the computing process. Please fix this issue and fix the issue that the computing process cuts off at the middle of nowhere.

super fun and I have a idea add a empty simulation but you can spawn planets by dubble clicking and add a another one for galaxies hope you will accept the idea! also after you're done showing the simulation you tap the camera icon on the bottom right and take a picture of it and it will show you the aftermath and also you can also you can spawn moons and put them in the roach limit so that way you can look at a planet with rings 🤩

What’s new

BIG update!

- Many new planet textures
- New shapes: cube, wall and disc alongside spheres
- Indestructible bodies: shapes keep their shape no matter what if you want them to.
- Save and load setups, with thumbnails.
- Shadows: real-time shadows with three quality levels (Off / Basic / Advanced). Advanced casts and receives shadows per particle.
- GPU rendering: planets now have correct depth and occlusion.
