## What is Lumen Path?

Light enters. You decide where it goes.

Lumen Path is a laser puzzle set on a dark optical bench. Emitters fire beams
across a grid of brass and blackened steel. Every target asks for one exact
colour, and it is lit only when it gets exactly that — not more, not less.

Tap a piece to turn it. That is the whole of the game.

WHAT YOU WORK WITH

• Mirrors that fold a beam ninety degrees
• Prisms that break white into red, green and blue
• Splitters that send one beam two ways at once
• Combiners that mix colours back together
• Filters, rotators, one-sided mirrors and portals

144 PUZZLES, ALL VERIFIED

Six chapters of twenty-four. Each one introduces a single new piece and then
exhausts it, so nothing arrives without being taught first — and it is taught
by the board, never by a wall of text.

Every level is verified before it ships: solvable, with a known shortest
solution, and with no piece on it that does not matter.

A PUZZLE A DAY

One generated board per calendar date, the same for everyone, harder as the
week goes on. Keep a streak. Miss a day and it starts again.

NOTHING TO READ ON THE BOARD

There is not a single sentence of instruction in the game. Colours are shown
as shapes as well as hues — a triangle, a circle, a square — so the rules read
the same whether or not you can tell red from green, and the same whether or
not you read English.

PLAYS THE WAY YOU WANT

• Fully offline. No account, no sign-in, your progress goes nowhere
• No energy, no lives, no timers, no waiting
• Undo is free and unlimited — think out loud on the board
• One hand, portrait, any time you have a minute
• Eight themes to change how the light looks

Stars are for arriving at a short solution, not for playing fast. Nothing is
locked behind perfect play.
