What's New in Space Crash Simulator

0.61

July 12, 2026

• NEW: Added Compute function for smooth replay (including rewind and slow-motion) on weak devices • NEW: Planetary rings! Give any planet a ring in Setup Mode — tilt it, resize it, watch it orbit, catch the planet's shadow, and rain glowing debris onto the surface. Or shred a moon into a ring with the tidal break-up action. • New Extras menu in setup (rings & orbit helpers) • Enter values directly without sliders • Graphics improvements

This is great

This is a fun game, but you can smash every planet. It’s OK have fun.

Very laggy and low fps

This would be a 5-star review but is its very laggy and low fps so please make the limit of fps higher then 30 bro🙏

Amazing update!

Amazing graphics!
Fun
Way more ways to simulate custom planets and systems.

The game won’t play

The game won’t play for some reason I think it’s bugged. The simulation won’t play.

Galaxy’s

Please make it so the galaxies can like forge together instead of just orbiting each other for an infinite amount of time and also add different types of galaxies like elliptical instead of only spirals
So good I really likeSo good I really like

FAQ

What is Space Crash Simulator?

Space Crash Simulator is a mobile application that uses Smoothed Particle Hydrodynamics (SPH) to simulate planetary collisions in real time. It allows users to witness and create detailed, physics-based cosmic events.

What are the key features of this app?

Key features include a robust SPH simulation engine for realistic planet collisions, a Setup Mode for customizing initial conditions like particle count and velocity, and adjustable settings to optimize performance on various devices.

Is Space Crash Simulator free to download?

Yes, the app is free to download and offers in-app purchases. It also includes advertisements.

Can I adjust the simulation settings?

Yes, you can customize initial conditions in Setup Mode. This includes adjusting parameters such as particle count, planet velocity, and collision accuracy to create your own unique collision scenarios.

What kind of devices can run this simulation?

The app is designed to be accessible on a range of devices. Settings like particle count, accuracy, and timescale can be adjusted to allow even less powerful devices to run the simulation effectively.
