Description
Universe Sandbox is a realistic physics-based space simulator that allows you to create, destroy, and interact on an unimaginable scale.
It merges real-time gravity, climate, collision, and material interactions to reveal the beauty of our universe and the fragility of our planet.
Simulate Gravity
N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.

Collide Planets & Stars
Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.
Create Your Own Systems
Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.

Model Planetary Climate
Watch sea ice grow and recede with the seasons because of a planet’s tilt - change the tilt and change the seasons. Or move planets close to a star and see the oceans boil away as the surface heats up.

Supernova a Star
Watch a supernova unfold by colliding two stars, cranking up their mass, or making them explode at your whim.

Explore Historical Events
Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.
And more...Build and terraform planets with 12 materials, including water, oxygen, & carbon dioxide
Stellar flares & volatile trails
Procedurally generated planets, stars, & galaxies
Pulsars
Light-warping black holes
Epic space lasers
Shape oceans & mountains on planet surfaces

About Universe Sandbox
Universe Sandbox is a physics-based space simulation game developed and published by Giant Army, a Seattle-based studio founded by designer Dan Dixon, who released the original Universe Sandbox back in May 2008. Work on a successor began in 2011, entering Steam Early Access on August 24, 2015, initially under the working title Universe Sandbox². In December 2018, this newer version was officially renamed to simply Universe Sandbox, with the original 2011 release renamed Universe Sandbox Legacy to distinguish between the two.
The game merges real-time gravity simulation, climate modeling, collision physics, and material interactions into a single sandbox, letting players explore the scale and fragility of the universe using genuine scientific data and Newtonian mechanics rather than simplified approximations. Players can place and manipulate objects drawn from an extensive library covering every major celestial body in the Solar System, along with tens of real stars, including Proxima Centauri, Betelgeuse, and Arcturus.
N-body gravity simulation runs at nearly any speed, letting players observe orbital mechanics unfold over seconds or millennia. Massive planetary and stellar collisions can be triggered and watched in real time, with the game modeling the resulting physical and material consequences. Climate simulation lets players adjust variables like solar output or atmospheric composition and watch how a planet's environment responds over time, offering both an educational tool and a demonstrative showcase for exploring theoretical scenarios that would otherwise require a supercomputer to model accurately.
Universe Sandbox continues to receive regular updates from Giant Army, expanding its simulation depth, object library, and visual fidelity well beyond its original Early Access feature set.

No. This is a newer, separate game originally developed under the working title Universe Sandbox², renamed simply Universe Sandbox in December 2018. The original 2011 release was renamed Universe Sandbox Legacy and is sold as a distinct product.
Both. The game is built around genuine scientific data and physics, making it a popular tool for educational demonstrations of gravity, climate, and celestial mechanics, while also functioning as an open-ended sandbox for experimentation and creative destruction.
The game is designed to run real physics simulations without requiring a supercomputer, though performance can vary depending on the complexity and scale of a given simulation, particularly with large numbers of objects or extreme time acceleration.
Yes. Giant Army continues to release regular updates expanding the game's simulation depth, object library, and visual features well beyond its original release.
