- Smoothed Particle Hydrodynamics (SPH) simulation
- Real-time planetary collisions
- Customizable simulation parameters
- Setup Mode for scenario creation
- Adjustable particle count and accuracy
- Physics-based detailed simulation

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
World Destroyer Simulator
Read full descriptionHide full description
Pick a world. Pick a weapon. See what's left. World Destroyer is a sandbox where a planet floats in front of you and you take it apart. Tap to fire, drag to spin it, pinch to look closer. Each strike leaves a crater, the crust cracks and glows, the population ticks down, and eventually there is nothing left but a ring of rubble and a report of what you did. THIRTY-THREE WEAPONS Seven categories on the rail down the right edge. Meteors, storms, comets, an extinction-class asteroid and a moon dragged out of orbit. Lasers and a plasma lance you drag across the surface to carve molten scars. A black hole that stretches the world and swallows it. A supernova. A cleave that splits the planet in two along the line you tap. Saucers, a dreadnought, a strike wing and a drone swarm. A kraken, a world-eating worm, a void dragon and something ancient that opens its eye. Volcanoes, quakes, tsunamis, an ice age and a plague. And three ways to fight back: a shield, a guardian satellite and a terraformer that heals the crust. TEN WORLDS An Earth-like world of eight billion. A jungle super-earth. A red desert with domed colonies. An airless cratered moon. A banded gas giant with nothing to crater and everything to stir. A lava world already on fire. A frozen ocean with cities under the ice. A water world where the cities float. A ringed violet world. A volcanic-glass planet lit by neon cities. Every one is generated on your device, down to the coastlines, the clouds and the night-side lights. WATCH IT DIE Damage is not a number hidden somewhere. Craters have depth. Lava glows in the cracks and cools over time. The clouds darken, the atmosphere turns the colour of smoke, fissures race across the crust, and a world that has taken enough keeps losing people between strikes. Slow time down to watch a nuke go off, or speed it up to watch a plague spread. MADE ON YOUR PHONE There are no downloads and no assets. Every texture, every sky, every sound is synthesised when the app opens, which is why it is small and why it works with no connection at all. NOTHING ELSE No account, no sign-in, no ads, no purchases, nothing collected. Settings has a switch to reduce flashing for anyone sensitive to bright light.

Verdict
The clearest difference is in-app purchases: World Destroyer Simulator at none against Space Crash Simulator's 1. World Destroyer Simulator also leads on ads (none vs shown). Space Crash Simulator's advantage is iOS requirement (15.0 vs 17.0). On price and device support there is nothing between them.
