Made of small things.

This fictional creek is rendered as a single real-time 3D scene. Its pan, gold and water are modeled and stylized for play; they are not scans of historical equipment or a scientifically validated simulation. Natural-looking materials do not make the scene photorealistic.

A quiet game, not a promise

All gold amounts are virtual. Deposit mixtures are fictional. There are no real prizes, purchase offers or financial returns. Gold is enlarged for visibility, sediment uses a bounded two-dimensional material model displayed in 3D, and spilling is forgiving: valuable finds wait in the recovery tray.
