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. Game Features: • Realistic physics engine and mechanics. • Dynamic universe creation and amazing phenomenon. • Immersive 3D environments and stunning graphics. • Gravity simulator with solar systems to discover. • Interactive journal to track your universe simulator 3D. • Embark on a journey through space, where you can craft your own universe within a universe sandbox, explore the solar system simulator, and experiment with the laws of physics in a space sandbox. • With Universe Space Simulator, the cosmos is at your fingertips—ready to be shaped, explored, and understood How to Play: • Discover Sandbox Planets, design and create your own solar system, galaxy, universe, and space, and enjoy watching them orbit, • collide, and interact in a cosmic dance in your space sandbox. • Start with a small asteroid absorbing other asteroids to form a solar system. • Adjust the galaxy speed as you like it most. Explore how life develops in your solar system through the planet journal. • Screenshot your complete galaxy with stars and share it with family/friends. Universe Gravity Simulator 3D offers endless possibilities for fans of outer space games, whether you're into astronomy games, arcade action, or stargazing in a planetarium 3D environment.

About

Gravity Physics

Features
Read full description

Gravity is a real-time N-body physics simulation of our solar system — fly a spacecraft through accurately modeled orbits, gravity wells, and atmospheres, all rendered in a clean top-down view of the ecliptic plane. Every body uses real physical data: mass, radius, orbital elements, and atmospheric density where applicable. Gravity between all 26 bodies — Sun, planets, major moons, and dwarf planets — is computed live using velocity Verlet integration, so orbits, perturbations, and gravity assists emerge naturally from physics, not scripted paths. FEATURES • Pilot your own spacecraft — configure engine count, thrust, and mass, then launch from Earth • True N-body gravity — every body pulls on every other body and on your ship, in real time • Realistic atmospheric drag and heating — feel the difference between skimming Earth's atmosphere and diving into Venus or Saturn • Time controls — speed up months of orbital motion or slow down to precision-dock in real time • Trajectory prediction — see where your current heading will take you before you commit • Flight trail — trace your path across millions of kilometers • Extended telemetry — track speed, altitude, gravity, thrust-to-weight ratio, dynamic pressure, hull temperature, time dilation, and more Whether you want to attempt a Hohmann transfer to Mars, slingshot past Jupiter, or just watch the Moon orbit Earth in fast-forward, Gravity gives you a physically accurate sandbox to explore the mechanics of our solar system.

Verdict

The call

The clearest difference is in-app purchases: Gravity Physics at none against Universe Gravity Simulator 3D's 1. Gravity Physics also leads on update cadence (weekly vs every 5 weeks). Universe Gravity Simulator 3D's advantage is iOS requirement (12.0 vs 17.6). On price, ads and device support there is nothing between them.
