What is Universe Sandbox ?

Universe Sandbox is a physics-based space simulator.


It merges gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.


Create, destroy, and interact on a scale you've never before imagined.

What can you do with Universe Sandbox ?  

Simulate Gravity

N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.

Earth & Moon Collision

Collide Planets & Stars

Epic, mind-blowing collisions of massive planetary bodies.



Create Your Own Systems

Start with a star then add planets. Spruce it up with moons, rings, comets, or even a black hole.


Model Earth's Climate

Watch sea ice grow and recede with the seasons because of the tilt of the Earth: change the tilt and change the seasons. Or move the Earth farther from the Sun and freeze the entire planet.

What Are People Saying About It?

It's easy to use, beautifully tutorialised, and hugely fascinating.

Rock Paper Shotgun

I just finished playing and my mind is blown. I spent most of my time staring at the screen, smiling like an idiot.

Dan & Matt

[Universe Sandbox] is one of the coolest things I've used on Vive so far.

Tom Marks, PC Gamer Assistant Editor

Most epic moment - increased the mass of the sun when it suddenly flashed insanely in a giant supernova. Epic touch.

Take on Mars developer

...a vast improvement over the original. ... an incredibly enjoyable simulator.


This simulator will blow your mind. I love it.

Michael, Vsauce

Everyone should be playing Universe Sandbox.

Neill Blomkamp, writer & director of the films District 9 & Elyisum

To describe the simulated destruction of Earth as satisfying is to undersell the delight of a child with a magnifying glass and some plastic soldiers.


I just love this stuff. I could explore this game all day.


Love this program. So pretty. You guys really outdid yourselves!!

The Professor, Know Idea 4zzzfm

It's like my great grandfather always used to say, 'Nothing like destroying 45 simultaneous instances of the Milky Way to brighten up a bad day.'


If the water starts to evaporate, this might be one of the best games ever made... [water evaporates]


Space is so cool!

A space simulator like no other: The Sims meets Elite meets Stephen Hawking's archives.

Red Bulletin

This simulator really puts you in the driver's seat to the universe we live in.
