LIGHT BEAM REFLECTION
Redirecting beams of light with mirrors, prisms, and lenses to hit targets, activate sensors, or burn obstacles — the classic optics puzzle.

Zelda institutionalized it (Ocarina of Time's mirror-and-sun temple puzzles), The Talos Principle builds connector-beam routing into its core vocabulary, and dedicated puzzlers like Lara Croft and the Guardian of Light and countless mobile games run mirror-grid puzzles pure. Designers love beam reflection because it's self-explaining physics with perfect feedback: the beam is its own visualization — players see exactly where light goes, where it stops, and what's in the way, so iteration is instant and wordless. It also composes cleanly: add splitters, colors that mix, movable emitters, or beam-blocking enemies and the same base rule yields escalating complexity. Beams naturally connect distant spaces too, making them level-design connective tissue that forces players to read whole rooms. Key decisions: continuous angles versus grid-locked 45°/90° mirrors (grids keep solutions crisp and forgivable; free rotation adds fiddliness fast), whether beams persist or need sustained sources, and what beams do beyond unlocking — damage, revealing hidden geometry, and charging objects give the mechanic combat and exploration lives. Pitfall: precision fiddling — when the puzzle is solved in the player's head but the mirror needs pixel-perfect nudging to register, the remaining 'challenge' is fighting the controls, which converts an aha into an argh.
