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.

Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
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 22 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,513 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

Sums Steam only; Xbox, GOG, Epic publish no volume signal, so the true total is higher by an unknown amount.
Updates
Build ids and update times come straight from Steam's PICS — the same source SteamDB reads. Patch history grows as we record new builds.

[b]Spójrz ponownie na tę kropkę. To Nasz dom. To my. Na niej wszyscy, których kochasz, których znasz. O których kiedykolwiek słyszałeś. Każdy człowiek, który kiedykolwiek istniał, przeżył tam swoje życie. To suma Naszych radości i smutków. To tysiące pewnych swego religii, ideologii i doktryn ekonomicznych. To każdy myśliwy i zbieracz. Każdy bohater i tchórz. Każdy twórca i niszczyciel cywilizacji. Każdy król i chłop. Każda zakochana para. Każda matka, ojciec i każde pełne nadziei dziecko. Każdy wynalazca i odkrywca. Każdy moralista. Każdy skorumpowany polityk. Każdy wielki przywódca i wielka gwiazda. Każdy święty i każdy grzesznik w historii Naszego gatunku, żył tam. Na drobinie kurzu zawieszonej w promieniach Słońca. Pomyśl o rzekach krwi przelewanych przez tych wszystkich imperatorów, którzy w chwale i zwycięstwie mogli stać się chwilowymi władcami fragmentu tej kropki. Naszym pozom. Naszemu urojonemu poczuciu własnej ważności, naszej iluzji posiadania jakiejś uprzywilejowanej pozycji we wszechświecie, rzuca wyzwanie ta oto kropka bladego światła. Nasza planeta to samotny pyłek w bezmiarze wielkiego, otulającego nas kosmicznego mroku. W naszej nikłości, w tej rozległości wszechświata, brak jest nawet cienia nadziei, że pomoc nadejdzie skądinąd, by nas ocalić od nas samych. Ziemia to jedyny znany dotąd świat, który gości życie. Nie ma żadnego innego miejsca, przynajmniej w najbliższej, dającej się przewidzieć przyszłości, dokąd nasz gatunek mógłby się przenieść. Odwiedzić – tak. Osiedlić się – jeszcze nie. Chcąc nie chcąc, na razie Ziemia jest miejscem, gdzie musimy trwać. Mówi się, że astronomia to doświadczenie uczące pokory i kształtujące charakter. Nie ma chyba lepszego świadectwa na próżność ludzkich ambicji, niż ten odległy obraz naszego maleńkiego świata. Dla mnie to uwydatnia naszą odpowiedzialność, by obchodzić się ze sobą życzliwiej, oraz by pielęgnować i kochać z całego serca tę bladoniebieską kropeczkę – jedyny dom, jaki kiedykolwiek było dane nam poznać.[/b] [i]-Carl Sagan, Błękitna kropka. Człowiek i jego przyszłość w kosmosie[/i]
