About This Game
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
Spin planets apart with centrifugal force
Original soundtrack by Macoubre
Support for 20+ languages

this game is fun. i like making random systems, reenacting the 3 body problem, and recreating systems shown in movies. i like this game, you should play it.
Want to blow up earth? Want to Make Mars Green? Want to Explode your PC? Well, if yes, this is your PERFECT GAME. I had so much fun with this, and i plan to play even MORE! I would totally reccomend dis masterpiece of a game, even if it's a little pricey.
This game is super realistic! When I went towards the sun, I could feel the heat melt my face off!
Why tf would you remove the vr. Wtf is the point of this? Refund me if youre going to be a liar. Youre a horrible creator. I pay for a vr game and then you remove that. Give me my fucking money back.
Demanding on your hardware (as to be expected, lol), but an INCREDIBLE simulator. It can serve as a worldbuilding tool, and a brilliant educational tool. The level of knowledge you can pick up about astronomy just from fiddling around and being curious is incredible. 100% recommend supporting this.
[Scroll to the bottom for a simple review sheet] Over the (only) 26.2 hours that I have played Universe Sandbox, so many improvements have happened within the game. When I first started playing Universe Sandbox, the game was pretty laggy, glitchy, and overall difficult to understand. However, the team behind this wonderful game has made so many useful improvements and actually listened to what the community has suggested, leading to an overall wonderful experience playing it. The graphics themselves are very easy to customize, so you can still play the game even on a low-end computer. Even with graphics turned significantly down, however, the visuals are still stunning. In conclusion, Universe Sandbox is an awesome game with creative and caring developers, and I would recommend it to almost anyone. However, it is easy to get burnt out on it if you play it too often, as are most sandbox games. Simple Review Sheet: Audio Quality (0-10): 8 Graphics Quality (0-10): 9 Gameplay Quality (0-1...
a nice game about destroying planets, a little confusing at first but fun when you get the hang of it!
This is fun to play around with every once in a while but the price point is just way too high. I got it on sale for $20 and even that feels like too much for what you get here. Something around $10 feels more fair.
Literally telling me my 12 core, 128gb ram, Vega GPU computer, that has already played the game, is so hardware incapable, that it won't even let me try to play the game. Don't pay lazy developers who just use hardware claims and driver updates as excuses for their bugs and ineffiencies.
