Lumen Loop: Light Puzzle

Guide a beam of light through mirrors, prisms, filters and portals until every target glows in the right colour. Easy to start — and then it really starts thinking back.

A REAL DIFFICULTY CURVE
The first levels teach you to turn a mirror. A few worlds later the mirrors are scattered across the board, some pieces are decoys you don't need, and two separate beams must be built without touching each other. Every tenth level is a Trial: the toughest puzzle of its stretch, with double rewards.

• 280 hand-tuned levels across 14 worlds, each one verified solvable
• Mirrors, splitters, prisms, colour filters, combiners and portals
• Red, green and blue light mix into new colours — targets only light up in the right one
• Trial levels, world chests and a player level that grows with every solve

A REASON TO COME BACK EVERY DAY
• A fresh daily puzzle for everyone
• Three daily missions with a bonus chest for finishing them all
• A 7-day reward calendar with a mystery chest on day 7
• A weekly star challenge
• Relaxing endless Zen mode

MAKE IT YOURS
Unlock beam themes — Neon, Ember, Crystal, Aurora, Solar and Void — by levelling up, with lumens or in the store. Themes change the scene, never the puzzle.

FAIR TO FREE PLAYERS
Every level can be finished without paying. Stuck? A hint places one piece correctly, and when you're out of lumens a short optional video gives you a free hint. The game shows ads; the Remove Ads item or the one-time Luminary Pass turns them off. No subscriptions.
