About Solar Sandbox

Step into a universe of endless creation and cosmic wonder in Solar Sandbox—a groundbreaking, free-to-play simulation that lets you shape galaxies at your fingertips. Designed for browser play on itch.io, Solar Sandbox is the ultimate playground for fans of physics, astronomy, and creative experimentation. Dive into a realm with over 42+ distinct celestial objects and immerse yourself in a seamless, ad-free environment crafted by passionate indie developers. Whether you want to ignite supernovas, build planetary systems, or experiment with black holes, this game unleashes your imagination with live gravity simulation powered by state-of-the-art physics. Newcomers and seasoned simulation fans alike will be hypnotized by the intuitive controls and smooth performance.

Each action feels significant: watch as asteroid belts swirl, gas giants collide, or a newborn star pulls planets into orbit. The handcrafted soundtrack by Nikita Shaposhnikov elevates your cosmic creations with atmospheric music, making every session a contemplative, relaxing escape. No object limits mean you’re free to test theories, invent celestial patterns, and simulate chaos—without ever facing an intrusive pop-up ad. Solar Sandbox's polished main menu empowers you to dive straight into experimentation, while its thriving Discord community ensures your feedback shapes future updates and features.

Unlike any standard browser sim, Solar Sandbox is an ever-evolving project fueled by player collaboration. Spot a bug or have an idea for a cool new planet? The devs want to hear from you, promising a truly player-driven experience. As new objects, mechanics, and updates loom on the horizon, now is the time to spark your curiosity, unleash creativity, and build a beautiful cosmic sandbox uniquely your own. Are you ready to become a master of the universe?

How to Play

Starting your adventure in Solar Sandbox is quick and intuitive. Once you launch the game in your browser, you’ll be greeted by a sleek, well-made main menu. Simply click 'Start' to enter the cosmic playground. The left panel offers over 42+ unique objects, from glowing stars and volatile black holes to mesmerizing asteroid fields and icy planets—just click to select your desired object. To place an object, point your cursor anywhere on the starry canvas and left-click. If you want to fling it into space with momentum, drag your mouse in the desired direction for a dynamic launch.

Gravity takes charge from there. Watch how planets orbit, stars attract, or comets race along surprising trajectories—all governed by real-time physics simulation. Use your mouse to click, drag, and reposition celestial bodies, or right-click an object to remove it from the system. Zoom in and out with your scroll wheel to get the perfect vantage point for your interstellar experiments. The top toolbar offers immediate controls for resetting the simulation, pausing time, or clearing the cosmos if you want a fresh start.

Beginners should experiment with simple two-body orbits, while more advanced players can create complex galaxies, test chain-reaction supernovas, or craft stable planetary systems. Don’t be afraid to get creative—there are no limits or wrong answers. Be sure to explore all objects and combinations, and if you discover something cool or hit a snag, use the built-in feedback link to help shape the game’s future. Above all, enjoy the freedom to build, destroy, and remix the laws of the universe—all from your browser.
