Inside the workshop
Choose a challenge, assemble the route, then let the simulation run.
A compact physics workshop
Place
Snap ramps, rails, curves, funnels, splitters, bumpers, springs, gates, sources, and goals to the board.
Run
Release a nine-marble batch and follow it through deterministic collisions, rolling, sleeping, and goals.
Refine
Pause, edit, rotate, remove, undo, and share compact machine codes without losing the current build.
