About this game

Place bulbs on a dark grid and light every open square.

Numbered walls show exactly how many bulbs belong next to them. Bulbs cannot shine directly at one another, so use logic to illuminate every row and column without creating a conflict.

Lumen Grid is a casual logic puzzle built around the satisfying moment when a dark board glows to life.
