FAQ
Common questions
Is this an official Websim project?
No. This is an original local 3D Cube Playground built for this fan-made site.
How are large numbers shown?
Large numbers use grouped stacks so the page stays responsive instead of rendering every single cube.
Can I rotate and zoom on mobile?
Yes. Drag on the canvas to rotate. Use fullscreen for a larger touch target on phones and tablets.
