How to Play Light Beam
Use A and D or Left and Right Arrow to select an optical component. Press Q and E to rotate the selected component, or click an optic directly and use the on-screen rotation buttons. Mirrors turn the beam, splitters create a straight and side branch, and prisms route light into two directions. All receivers must be powered simultaneously to complete the puzzle. Complete all six optical benches using as few rotations as possible. Press P to pause, M for sound, F for fullscreen and R to restart.
About Light Beam
Light Beam is a single-player browser optics puzzle built around branching light paths. A single emitter must power several receivers at the same time. Mirrors redirect beams by ninety degrees, splitters keep one branch moving while creating another, and prisms send light into two adjacent directions. Plan the complete network so fixing one receiver does not disconnect another.
