Bend beams of light through mirrors, prisms and portals
Lumen Loop: Light Puzzle is a beam-routing puzzle game by Rui Codex for Android. Players place mirrors, splitters, prisms, color filters and portals so every target lights up in the right color, across 280 levels in 14 worlds. Puzzles work offline, and the game is free with ads and optional purchases.
Scroll sideways or use the arrow keys.
Hand-tuned puzzles, each verified solvable, with a Trial every tenth level.
Red, green and blue combine into new colors, and targets need the right one.
Mirrors, splitters, prisms, color filters, combiners and portals.
A fresh daily puzzle, three daily missions and a weekly star challenge.
A relaxing endless Zen mode and an endless ladder of puzzles after the campaign.
Neon, Ember, Crystal, Aurora, Solar, Void and more, purely cosmetic.
Each level is a board with a light source, a set of pieces and one or more targets. Turn mirrors and place splitters, prisms, filters, combiners and portals until every target glows. Red, green and blue light mix into new colors, and a target only lights up in the right one, so later boards are as much about color as about angles.
The difficulty curve is deliberate. Early levels teach a single mirror; a few worlds later, mirrors are scattered across the board, some pieces are decoys, and two separate beams must be built without touching each other. Every tenth level is a Trial, the hardest puzzle of its stretch, with double rewards. All 280 levels across 14 worlds are hand-tuned and verified solvable, and the Deep Field adds an endless ladder after the campaign.
A daily puzzle, three daily missions, a seven-day reward calendar and a weekly star challenge give a reason to return, and a relaxing Zen mode has no goals at all. Beam themes such as Neon, Ember and Aurora change the look, never the puzzle. Every level can be finished for free, a hint places one piece correctly, and Remove Ads or the one-time Luminary Pass turns ads off. No account is needed.
Puzzle players who like spatial logic and optics, from casual players learning the first mirror to those who want genuinely hard boards.
