About this game
A beam of light leaves an emitter. Mirrors stand in its path. Turn them until
the light reaches every core — and not one hazard.
That is the whole game. No timers, no lives, no energy meters, no ads
interrupting a puzzle you are in the middle of. Just you and a board that has
exactly one right answer.
ONE RIGHT ANSWER, NOT A LUCKY GUESS
Most puzzle games let you flail your way through the early levels. Lumenlock
does not. Every board is checked by a solver before it ships, and the number of
winning configurations is capped — most levels have precisely one solution.
Flipping mirrors at random stops working on level 1, not level 40.
PAR IS THE TRUE MINIMUM
Every level shows a par: the fewest mirrors you have to change to solve it.
That number is not a designer's guess. It is computed by brute force, so when
the board says par 6, six is genuinely the shortest route that exists.
Three stars means you found it. Two means you solved it the long way. There is
always a reason to come back to a level you already beat.
Scoring counts the mirrors you changed, not the taps you made — so
experimenting is free, and undo can never be farmed for an easy three stars.
250 LEVELS ACROSS NINE ACTS
Each act introduces exactly one new idea, and nothing is ever explained with a
wall of text:
• REFLECT — turn a mirror, bend the beam
• DEFLECT — longer routes, walls in the way
• TWIN BEAMS — two emitters sharing the same mirrors
• SPLIT — beam splitters send light two directions at once
• HAZARD — hazard cores punish a sloppy route
• SPECTRUM — colour filters, and cores that only accept their own colour
• OVERLOAD — every mechanic at once
• CASCADE — three cores, one beam
• LOCKDOWN — the hardest boards in the game
The early levels are gentle enough to teach themselves. The late ones are not.
BUILT TO RESPECT YOUR TIME
• Plays entirely offline — no account, no sign-up, no connection needed
• Nothing is ever locked behind a countdown
• Hints are earned by playing, not withheld to sell back to you
• Instant restart, unlimited undo, no fail state
• Dark, low-glare visuals designed for long sessions
A QUIET GAME
Lumenlock looks like an optics bench in a vacuum chamber. Cold light, brushed
steel mirrors, a warm amber core when you get it right. No cartoon mascots, no
confetti, no shouting.
If you like Nonograms, Sudoku, Flow, Bloxorz, or anything where the answer is
sitting there waiting for you to see it, this will feel familiar.
Free to play, with an optional one-time purchase to remove ads.
