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 valid configurations. ⭐ EARN THREE STARS • Solve fast → keep more time bonus • Fire fewer probe lasers → keep more efficiency bonus • A clean run on a 12×12 grid is the brag-worthy goal 📱 DESIGNED FOR THE COMMUTE • One-thumb portrait gameplay • Works fully offline • Saves your progress automatically • No login, no email, no account creation • Soft procedural sound — keep headphones in, or play silent ✨ FEATURES • 50 hand-tuned levels across 5 grid sizes • Smart hint system — watch a quick ad to reveal one mirror when stuck • Star-rating system that rewards efficient play • Neon visual style with smooth scene transitions • Subtle haptic feedback on cell taps and laser fires • Custom procedural audio — no music files, instant install 🎯 WHO IT'S FOR If you enjoy Sokoban, Lasers, Light Up, Hashi, Slitherlink, Nonograms — or just like games where the only opponent is the puzzle itself — this is for you. 🔒 PRIVACY • No analytics tracking your gameplay • No accounts, no email, no profile • Banner and rewarded ads are served by Google AdMob — see our privacy policy for what AdMob collects Crack the first level in 30 seconds.
