Lumen Light: Neon Logic Puzzle

Lumen Light is a calm, clever routing puzzle drawn in neon.

Pulses of light pour down glowing paths. Swipe a switch, or tap the path you want, and send each pulse to the outlet with its shape: cyan circles, amber squares, green diamonds. Some pulses carry marks and must pass the matching gate first, and gates only take pulses marked for them.

EVERY LEVEL HAS A PAR
Clearing a level is easy. Clearing it in the fewest switch flips is the puzzle. Each level's par is the proven minimum, found by a solver, so three stars is always possible and never free.

EARN SPECIALS
New stars earn Sparks. Spend them on Peek (see every pulse still to come), Hold (pause the emitters for a moment) or Shield (forgive one wrong turn). Specials are earned by playing and never sold. A run that uses one can earn up to two stars.

CLIMB THE STARS BOARD
Race everyone on the Open board, where free and Pro players are ranked on the same free levels. Pro players also climb the Full ladder across every level. Every result is checked by replaying your moves with the game's own rules. No account needed.

MADE FOR EVERYONE
Every colour has its own shape, so no rule depends on telling colours apart. Sound and haptics can be switched off separately, and Relaxed speed slows every level down.
