About the game
Solve twelve original light-routing puzzles by rotating mirrors and beam splitters.
Fixed colour filters and receivers turn each optical bench into a precise spatial puzzle: crossing beams stay independent, while a receiver combines the colours that actually reach it.
Every puzzle is selectable, with a shortest-rotation par, undo, redo, optional hints and device-saved progress.
The interactive Three.js 3D bench and playable 2D grid use the same rules.
Hinted practice cannot replace an unassisted best.
Results also appear in the shared local arcade profile.
This is a simplified puzzle game, not a scientific optics simulator, online multiplayer or cloud-save service.
