## What is Lumen?

Place a mirror. Bend the beam. Light the crystal.

Explore an optics workshop, a prism laboratory, an observatory and a light tower. Each building has its own atmosphere, with brass instruments, stone floors and rooms to discover.

Start on a small board, learn how reflections work and move on to larger puzzles. Walls block your path, mirrors change its direction, and every placement matters.

Higher up, the light plays by new rules. In the observatory, lenses change its color and colored glass lets only the matching color through. In the light tower, portals carry the beam across the board and a splitter sends it two ways at once.

Take your time in most rooms. In others, the light can travel only so far, or slowly burns down while you find a route.

Catch coins with the beam and spend them on hints when you need a hand. Return to completed rooms to try another path and earn more stars.

Tap to place and turn a mirror. Hold it to remove it. Simple controls leave room for the puzzle.

The optics workshop is free to play. Lumen Unlimited, a one-time purchase, opens the prism laboratory, the observatory, the light tower and every building still to come. If you played before this update, every building you reached stays open.

Every building you finish offers walks: fresh puzzles made on the spot from that building's pieces. Five every five hours, or as many as you like with Lumen Unlimited.

Play offline on your phone or tablet. Available in English, Polish, Ukrainian and Russian. No ads and no account required.


## Version history (last 3 releases)

### 1.2 — 2026-09-29

The optics workshop stays free. Lumen Unlimited, a one-time purchase, opens every building above it and every one still to come. Buildings you reached before this update stay open.

Walks: every building you finish now makes new puzzles on the spot.

Calm music on the menus and quiet sounds on the board. A new icon, new Settings and a new level map.

Fixed: closing the panel after the light went out left the screen dark.

### 1.1 — 2026-09-23

A new building: the light tower, with 32 new puzzles. Send the light through portals and split it between two crystals. The observatory has new puzzles too: lenses change the color of the light, and colored glass lets only the matching color through. The game now has an ending, a new title screen and new art for every building. Rate the game in Settings any time. Resetting your progress now asks first.
