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.

About

Space Crash Simulator

Experience realistic planetary collisions with a powerful physics engine. Customize your own cosmic events by adjusting particle count, velocity, and accuracy, or jump straight into high-energy impacts. This app offers a detailed, physics-based simulation for educational or entertainment purposes.

Highlights
  • Smoothed Particle Hydrodynamics (SPH) simulation
  • Real-time planetary collisions
  • Customizable simulation parameters
  • Setup Mode for scenario creation
  • Adjustable particle count and accuracy
  • Physics-based detailed simulation
Features
Read full description

Smash worlds together and watch them shatter, merge, and melt, driven by real physics, not pre-made animations. Every planet is made of thousands of interacting particles, so every collision is computed live and no two impacts ever look the same. Build your own scenario in Setup Mode: place up to 8 bodies, set their size, density, spin and velocity, then let gravity do the rest. Or dive straight into a head-on collision and watch the debris glow, cool, and form a crust. - True particle physics (SPH), the first of its kind on mobile - Molten impact zones: heat, lava, and cooling crusts - Give planets rings or shred a moon into one with tidal forces (Roche limit) - Protoplanetary disk and colliding-galaxies modes - Black holes that tear planets apart - Custom planet textures from your own photos - Runs on everything: tune particle count, accuracy, and timescale to your device

Verdict

The call

The clearest difference is review sentiment: Space Crash Simulator at 81% against Universe Gravity Simulator 3D's 43%. Space Crash Simulator also leads on rating (4.5 vs 4.0) and update cadence (every 5 days vs every 5 weeks). Universe Gravity Simulator 3D's advantage is ads (none vs shown) and iOS requirement (12.0 vs 15.0). On price, in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

Space Crash Simulator holds the better App Store score, 4.5 against 4.0. That said, the two scores are not equally well evidenced: Space Crash Simulator has 723 ratings behind it against 142, 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 81% of Space Crash Simulator's.

UpkeepUpdate frequency

Universe Gravity Simulator 3D ships an update every 5 weeks, Space Crash Simulator every 5 days. Both last shipped on October 25, 2026.
