Space Sandbox

About Space Sandbox: Build and Destroy Your Own Universe

Space Sandbox is a bright 3D game where the entire premise is creative freedom — build a cosmic system, watch it evolve, or push it into spectacular chaos. From the moment you open it, the goal is clear: populate empty space with planets, moons, stars, gas giants, and black holes, then let gravity do the rest. You'll find no strict rules, no win conditions, and no failure states — just your experiments and their consequences.

The simulation tracks orbital trails beautifully, and ready-made scenarios give you a starting point if you'd rather tweak an existing system than build from scratch. Progress saves automatically, so a carefully balanced solar system is never lost between sessions.

Several scenes show a large yellow glowing sphere encircled by thin concentric rings with smaller bodies orbiting around it. One scene places a blue textured sphere with green and white patches at the center of the frame. Another moment shows a green wireframe cube containing a smaller green sphere inside it.

How to Play Space Sandbox

Placing and Selecting Objects

• Open the left menu and choose an object: planet, star, moon, gas giant, or black hole.
• Click anywhere on the space scene to place the chosen object.
• Click any existing object to select it.

Object Actions

Once an object is selected, several actions become available:

• Focus the camera on it
• Track it as it moves
• Boost it
• Stabilize its orbit
• Delete it

Simulation Controls

• Adjust time speed to watch planets move faster and observe how the system evolves.
• Adjust gravity to make the simulation calm, realistic, or chaotic.

Controls

• Left-click on scene: Place the selected object
• Left-click on object: Select it
• Double-click: Focus camera on an object
• Mouse wheel: Zoom in and out
• Right mouse button / Hold Shift: Move the camera
• Pinch gesture: Zoom on touch devices
• Drag with two fingers: Move the camera on touch devices
