Lumen: Relaxing Loop Puzzle

Lumen is a calm, beautiful logic puzzle built around a single rule: light the glowing pearls and draw one continuous loop through the grid. White pearls ask the loop to pass straight through. Black pearls ask it to turn. Every puzzle has exactly one elegant solution, and the quiet satisfaction of finding it is the whole point. There is no timer and no pressure. Solve one puzzle on a coffee break, or sink into a long, meditative streak. Lumen is designed to slow your mind down, not speed it up. Features: - A fresh hand-crafted puzzle every day - Hundreds of puzzles across gentle to genuinely tricky - A clean, glowing visual style made to relax - Smart hints when you want a nudge, never forced - Play offline, anywhere, anytime Lumen is free to play. An optional one-time unlock opens the full puzzle library. Terms of Use (EULA): https://policies.superfuturelabs.com/lumen/terms Privacy Policy: https://policies.superfuturelabs.com/lumen/privacy
