About game

Sandbox Universe turns your browser into a playground where you manipulate celestial bodies. You drag planets into orbit and watch how gravity dictates their chaotic future paths. Placing a new star or a dense black hole shifts everything in the vicinity instantly. Collisions create spectacular explosions that scatter debris across the dark void. You adjust the mass and temperature of every planet manually to see if your creation remains stable. Controlling the timeline allows you to fast-forward through millions of years to witness the long-term evolution of your custom galaxy. Sandbox Universe gives you total creative freedom to build solar systems or destroy them with a single click. Play this space simulator for free right now in your browser without any downloads required.

How to play

1. The game starts with the Solar System. Rotate the camera with your mouse or finger, zoom in with the scroll wheel or pinch gesture.
2. Tap "+" on the toolbar to add an object — choose from a catalog of real stars, planets, and other bodies.
3. Tap an object to view its properties: mass, radius, temperature. You can adjust the parameters and watch how they affect orbits.
4. Control time with the speed-up and slow-down buttons.
5. Open Scenarios — load a pre-built system or start from an empty sandbox.
6. Experiment: crash planets together, create binary stars, feed a black hole!

Features

Gravity Engine: Every object interacts based on real physics so orbits react dynamically to your changes.
Property Editor: Modify the mass or radius of any celestial body to observe how these changes impact orbital mechanics.
Destructive Collisions: Slam massive objects together to see how they merge or shatter into smaller fragments.
Scenario Browser: Load pre-built systems that range from simple solar models to complex binary arrangements.
Time Dilation: Alter the simulation speed to watch planetary movements in real time or accelerate events to see long-term outcomes.

Who is this game for

Space enthusiasts and fans of physics sandboxes who enjoy experimenting with gravitational forces. Anyone who dreams of being a cosmic architect will enjoy testing how different stars and planets interact in a persistent, simulated environment without needing any complex installation or registration processes to begin creating.
