Welcome to Universe Gravity Simulator 3D, where the cosmos is your playground! This universe sandbox is the ultimate outer space game, combining elements of arcade games, alien shooter missions, and gravity-defying fun. Whether you're a casual gamer or a dedicated space enthusiast, this game will pull you in with its realistic simulation of outer planets, star realms, and intergalactic battles. If you've ever wondered what it feels like to be a planet creator or a planet destroyer, this solar system game puts the power of the universe in your hands! Imagine the thrill of building and shaping entire galaxies, adjusting orbits, growing stars, and watching your solar system evolve. But it's not just about creation—Universe Gravity Simulator 3D lets you engage in galaxy attacks, destroy planets, and even wipe out stars. You’ll command your own space force as you fight to protect your Earth, while also facing off against alien invaders in intense battles inspired by arcade classics like space invaders and galaxy attack. As you play, you’ll discover stars, tweak gravitational forces, and even set up interplanetary collisions, all in the name of fun. Have you ever stargazed and wondered what it would be like to explore Venus, Mars, or the outer reaches of the solar system? Or maybe you've daydreamed of being an astronaut, hurtling through the galaxy in a powerful spaceship, fighting off space invaders in a heroic space battle? Universe Gravity Simulator 3D allows you to explore all of these possibilities and more. The stunning visuals will transport you to far-off star realms where your spaceship sim becomes more than just a game—it's a journey through space and time, a space odyssey that blurs the lines between play and exploration.

Read full description

Zoom from a planet's surface out to distant galaxies, then reshape the whole system with your own hands. Solar System Sim is a real-time gravity sandbox built on Newton's laws and real astronomical data. Every body you add, move or destroy recalculates the orbits of everything else, live. • Smash worlds together: impact craters carve into the surface, firestorms sweep the globe, and glowing debris rains back down. • Build your own universe: add planets, moons, asteroids and comets with their own size, mass and looks, or customise the ones already there. • Land anywhere: drop to a first-person view on any planet's surface and experience its environment. • Sculpt rings: add particle rings and watch gravity shape them in real time. • Witness real eclipses: solar and lunar, with real-world astronomical precision. • Follow comets: watch them streak past and interact with the bodies they meet. • Leave the Solar System: travel to remarkable nearby stars and find them within the Milky Way. • Feel the scale: see the true vastness of space, from a pebble-sized moon to the nearest galaxies. Whether you're here to learn how gravity really works or just to break planets with it, explore at your own pace. Start your cosmic adventure with Solar System Sim.

Verdict

The call

The clearest difference is review sentiment: Solar System Sim at 80% against Universe Gravity Simulator 3D's 43%. Solar System Sim also leads on rating (4.5 vs 4.0) and ratings volume (4.1K vs 128). Universe Gravity Simulator 3D's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Solar System Sim holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Solar System Sim has 4.1K ratings behind it against 128, so its average is the more settled of the two. Written reviews point the same way: 43% of Universe Gravity Simulator 3D's written reviews are positive against 80% of Solar System Sim's.

UpkeepUpdate frequency

Universe Gravity Simulator 3D ships an update every 5 weeks, Solar System Sim every 3 weeks. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
