Create & destroy on an unimaginable scale with a realistic physics-based space simulator. Explore the beauty of our universe and the fragility of our planet. Use science to bend the laws of gravity, collide planets, boil away oceans, fire epic space lasers, and customize your universe.

Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 7.86/day in the week to Aug 21 → 9/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 25 chart moves that followed a price cut of more than 20% went a median of 10 places towards #1, and the 2,413 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.
About
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.
N-body simulation at almost any speed using Newtonian mechanics. Real science, real physics, no supercomputer required.
Epic, mind blowing collisions of massive planetary bodies that leave behind molten craters.
Start with a star, then add a planet. Spruce it up with moons, rings, comets, or even a black hole.
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.

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

Hitch a ride with spacecraft including Juno and New Horizons, or view a total solar eclipse.
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
Share & explore simulations on Steam Workshop

It's really good for showing people the scale of cosmic objects e.g. Betelgeuse next to our Sun.
really good, I would say that there is some quirky bugs sometimes and sometimes they're funny, and sometimes they ruin everything, but the handy debug tool is here, so yeah, good but a bit unpredictable

Absolutely fabulous and intoxicating for people who enjoy science, astronomy, and just like asking "What if?" I overwhelmingly recommend it!
# The Weight of Creation: Universe Sandbox Most games ask you to survive in a world. Universe Sandbox asks something far more unsettling: What happens when the world survives because of you? At first, curiosity takes over. You move planets. Change orbits. Create stars where none existed before. You experiment with gravity as if it were a toy. Then Earth disappears. A collision you didn't expect. A moon placed too close. A star made slightly too large. An entire world erased in seconds. And suddenly, the scale of what you're looking at becomes impossible to ignore. Every planet is a delicate balance. Every orbit is a silent agreement between gravity and time. Every stable system is the result of countless forces working together across millions of years. The universe feels eternal until you are given the power to break it. That's what makes Universe Sandbox so fascinating. It transforms physics from a collection of equations into something you can feel. You don't just learn how worlds are created. You learn how easily they can disappear. There is something strangely humbling about watching a civilization's home vanish because of a decision you made with a single click. Not because it is destructive. But because it reminds you how fragile existence truly is. Universe Sandbox is often described as a physics simulator. For me, it felt more like a lesson in perspective. A reminder that every world is a miracle. And miracles are far easier to destroy than they are to create.
I bought universe sandbox in 2015 near when it released and was still called "Universe Sandbox 2." I remember the original universe sandbox being a cool way to look at planets and when they'd collide they'd either go "pop" or "shlorp" and that was it. Since then Universe Sandbox became Universe Sandbox Legacy and Universe Sandbox 2 became the Universe Sandbox you see today. Since I bought this game way back in 2015 the game has constantly gotten updates, adding planets, features and has since became utterly stunning to just look at. and when planet collide it creates possibly the most beautiful thing I have ever seen in a video game. From comets to planets colliding to supernovae to galaxies "colliding" this game looks beautiful and manages to run great on my mediocre computer and somehow over a decade later the game is STILL BEING UPDATED! best 20 something quid I have ever spent.
11 years later and its still in "early access"

Universe Sandbox è più un laboratorio di simulazione spaziale e fisica interattiva che un videogioco tradizionale sviluppato da Giant Army, il software offre un livello di libertà praticamente illimitato sul cosmo. Cos'è Universe Sandbox? Non ci sono missioni, obiettivi o livelli da completare Il programma simula in tempo reale gravità, clima, collisioni e interazioni di materia su scala astronomica dai singoli asteroidi fino alle intere galassie. Punti di Forza ● Fisica N-body in tempo reale: Le orbite, le forze gravitazionali e le attrazioni tra corpi celesti vengono calcolate dinamicamente. ● Simulazione Climatica e Terrestre: Aumentando la luminosità del Sole o modificando la composizione atmosferica di un pianeta, la temperatura varia e i ghiacciai si sciolgono o si espandono. ● Sperimentazione Distruttiva: È possibile far collidere la Luna con la Terra, trasformare Giove in una stella aggiungendo massa, o scagliare un buco nero all'interno del Sistema Solare per osservare il caos gravitazionale. ● Supporto VR: Offre un'esperienza immersiva spettacolare in realtà virtuale, permettendo di ridimensionare lo spazio a portata di mano. Limiti e Criticità ● Assenza di Gameplay Tradizionale Chi cerca una trama o obiettivi specifici potrebbe stancarsi rapidamente dopo aver "distrutto" il sistema solare un paio di volte. ● Carico Hardware: Le simulazioni più complesse (come lo scontro tra due galassie con milioni di particelle) richiedono una CPU e GPU performanti per evitare rallentamenti. Verdetto Finale È uno strumento eccezionale per chiunque sia affascinato dallo spazio, dalla fisica o dal worldbuilding astronomico. Funziona benissimo sia come software educativo sia come "giochi di distruzione cosmica
