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.

Earth Sandbox is an experimental simulation game centered on Earth itself. Instead of following a fixed story or objective, the game invites you to explore how a planet reacts when its core systems are changed. Climate, gravity, oceans, and atmosphere interact dynamically, creating unique outcomes every time you experiment. You can adjust environmental conditions, trigger natural events, or push the planet into extreme states. Rising temperatures may reshape ecosystems, shifting gravity alters planetary balance, and sudden disasters can permanently change the world you observe. Natural events such as meteor impacts, earthquakes, volcanic activity, and global climate shifts are part of the simulation. Each event influences the planet differently depending on existing conditions, encouraging experimentation rather than repetition. The simulation is driven by interconnected systems inspired by scientific principles. Population trends, environmental stability, and planetary conditions evolve in real time, allowing you to observe long-term consequences of your actions. Features: • Earth-focused environmental simulation • Interconnected climate and planetary systems • Dynamic natural events and long-term world changes • Real-time population and ecosystem trends • Interactive tools designed for experimentation • Clean visuals with intuitive controls How will your choices shape the future of this Earth?

Verdict
The clearest difference is rating: Universe Gravity Simulator 3D at 4.0 against Earth Sandbox's 2.3. Universe Gravity Simulator 3D also leads on ads (none vs shown) and ratings volume (144 vs 12). Earth Sandbox's advantage is in-app purchases (none vs 1) and update cadence (weekly vs every 5 weeks). On price, review sentiment and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Universe Gravity Simulator 3D sells 1 one-off in-app purchase. Earth Sandbox asks for nothing beyond the download.
Universe Gravity Simulator 3D holds the better App Store score, 4.0 against 2.3. That said, the two scores are not equally well evidenced: Universe Gravity Simulator 3D has 144 ratings behind it against 12, so its average is the more settled of the two. Written reviews complicate that: 43% of Universe Gravity Simulator 3D's written reviews are positive against 50% of Earth Sandbox's, so the app with the better star average is not the one people write more warmly about.
Universe Gravity Simulator 3D ships an update every 5 weeks, Earth Sandbox weekly. The most recent releases landed on November 7, 2026 and November 9, 2026 respectively.
