Sandspiel

Paint with sand, water, fire, plants and other interacting elements in Max Bittker’s original simulation. Build a landscape, mix materials and watch what happens.

Choose an element, then paint on the board. Try water beside sand, seeds above soil, or fire near wood. This is a creative sandbox with no win condition.

Saves

Material layouts save locally after painting, every 20 seconds, and on Stop or tab hiding. Stop then Play restores the scene. Fluid velocity and simulation timing restart on load. Scenes stay on this device; there is no online gallery or account requirement. Clearing browser data removes saved scenes.

Sandspiel — help & credits

Mouse drag or touch paints the selected material. Brush size changes the stroke. Keyboard: Tab to the board, arrows move the visible cursor and Enter paints. Undo reverses a stroke. Freeze simulation lets you build a stationary scene. Clear scene starts fresh. Page Pause freezes the player; fullscreen gives more space.
