About & Contact

Welcome to Sand Pit Online — a little corner of the internet where sand falls, water sloshes, fire spreads, and the only rule is that you get to invent the rules. It's a falling-sand physics sandbox: pour substances into the pit, watch them tumble and react, and design your own materials with their own weight, colour, viscosity, and chemistry. Build a world, share it, and see what other people cook up.

Where it came from

Sand Pit Online started life as a humble university project. Somewhere between deadlines and too much coffee, a simple grid of falling pixels turned into a genuine obsession — the kind of thing you keep tinkering with long after the grade has been handed in. What began as an assignment quietly refused to be finished, and eventually grew into the full-blown creative playground you're looking at now.

The original spark came from an old browser classic: "Dust" at Dan-Ball. If you ever lost an afternoon flinging virtual powders around in Dust, you already understand the appeal. Sand Pit Online is a love letter to that feeling — the simple, hypnotic joy of watching stuff fall and interact — rebuilt for the modern web and opened up so you can be the one designing the stuff.

Who builds it

Sand Pit Online is designed, built, and maintained by a single independent developer. There's no big studio behind the curtain and no team of a hundred — just one person who thinks falling sand is genuinely wonderful and wanted to make a place for it to live. That means every substance, every fix, and every late-night improvement comes from the same pair of hands. It also means your feedback lands directly with the person who can actually do something about it.
