About this game

Space Crash Simulator is the first mobile app with Smoothed Particle Hydrodynamics (SPH) for planetary collisions. Watch as planets collide and break apart in real time, with a robust simulation running a decent number of particles for a detailed, physics-based simulation..

The simulation lets you jump straight into high-energy collisions or customize initial conditions in Setup Mode. Adjust parameters like particle count, planet velocity, and collision accuracy to create your own collision scenarios.

SPH simulations are notoriously resource intensive but settings like particle count, accuracy and timescale can be adjusted to allow even weaker devices to run it.

There is a bug in the new update where if you zoom out a bit, the planets dissappears. Although other than that, the update is great. and I love it. Thank you, and please fix this bug.

This game is very awesome but i perfer you adding more planet count, i started a channel named Jupiter0 and my most popular content got 1 million views from this single app the ads appear when you press the Set up button 2 times so please extend it to 5 times. Thanks -Westley (Jupiter0)

dont listen to the hate, the new updates are amazing, and to the people say "its so laggy!!1!1!!" just use less particles, but this is honestly the best space game ive ever played along with solar system simulator.

What’s new

- You can now add as many galaxies as you like
- Added set Roche button in setup
- replaced particle mass by planet density so you can make dense or loose planets irrespective of particle count
- Added real time lighting: planets have night and day sides, and cast shadows on each other
- You can now make planets much bigger by increasing their particle counts.
- Removed 2- and 3- body mode and replaced it with "Planetary Mode". In this mode you can add up to 8 planets in a scenario.
