Light Up

Light Up is a glowing logic puzzle. Place bulbs on the white cells: each bulb lights its row and column until it hits a wall.

Every white cell has to be lit, but two bulbs may never shine on each other. Numbers on the walls tell you how many bulbs sit right next to them - that's where you start.

A new daily puzzle every day - the same for everybody - plus unlimited practice puzzles in four sizes. Every puzzle has exactly one solution.
