Black Box: Photon Logic

THINK INSIDE THE BOX. Black Box: Photon Logic is a pure deduction puzzle. There is a grid. There are mirrors hidden inside it. Your job is to figure out where they are — using nothing but lasers fired from the edges. HOW IT WORKS • Tap any edge to fire a laser into the box. • See where it exits — that's your only clue. • Place / and \ mirrors on the grid to recreate the same exit pattern. • Match every laser path and the box is cracked. That's it. No tutorials, no hand-holding, no enemies, no timers stealing your stars. Just clean, focused photon-tracing logic. 50 LEVELS, ONE BIG CURVE From a 4×4 calibration with 2 mirrors to a 12×12 black box with 50 mirrors. Every level has a fixed seed — retry as often as you like, the puzzle never changes. Every level is solvable; some have multiple solutions.
