Sandbox Universe: Space Games

Welcome to Sandbox Universe, a 3D space simulator where you create your own solar system and watch real gravity bring it to life! Place stars, planets, moons, asteroids, comets, neutron stars and black holes anywhere in space, then see them orbit, collide, merge or tear each other apart. Build a calm and stable star system or unleash total cosmic chaos: this universe is yours to shape. CREATE YOUR OWN SOLAR SYSTEM Start with our own Solar System, or begin with an empty sandbox and a blank sky. Pick objects from a catalog of real celestial bodies, place them wherever you want and fine-tune every detail: mass, radius, gravity and orbital speed. Give a planet a new moon, add a second sun or design a brand-new star system that has never existed before. REAL GRAVITY IN ACTION Every object in Sandbox Universe follows the laws of gravity. Set a planet at the right speed and it will circle its star for ages; push it too hard and it will fly off into deep space or crash into its neighbors. Control gravity and the flow of time to watch your system evolve, and learn how orbits really work along the way. COLLISIONS AND BLACK HOLES Feeling destructive? Smash planets into each other and watch them break apart or merge into new worlds. Drop a black hole next to Earth, feed it planets and see stars get shredded by its pull. Every experiment ends differently, and that is what makes the sandbox so much fun. EPIC SPACE SCENARIOS Not sure where to begin? Try ready-made scenarios inspired by real astronomy and wild "what if" ideas: two stars dancing around each other, the giant impact that formed the Moon, the Sun turning into a black hole, Jupiter becoming a star or two black holes merging into one. GAME FEATURES 🌌 Create your own solar system in 3D 🪐 Stars, planets, moons, asteroids, comets and black holes 🔧 Change mass, radius, gravity and orbital speed 💥 Planet collisions that merge or destroy worlds ⚫ Black holes that swallow planets and tear stars apart 🌠 Ready-made scenarios from binary stars to Moon formation ⏩ Control the flow of time and watch your system evolve 🔭 A fun way to learn how gravity and orbits work Whether you are a curious beginner or a true astronomy fan, Sandbox Universe turns space physics into a playground. It is a space simulator, a planet builder and a gravity lab all in one. If you love space games, solar system simulators, gravity sandboxes and planet games, this universe was made for you. Build, experiment, destroy and start again: become the creator of your own universe!
