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

BIG update!
- Improved Compute and Replay, you can now record much longer and more stable
- 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.
- Black hole fix, rings fix
- Shadows: real-time shadows with three quality levels (Off / Basic / Advanced). Advanced cast and receive shadows per particle.
- GPU rendering: planets now have correct depth and occlusion.
