How to solve
- Light every cell: Every white cell must be lit by at least one bulb.
- Bulbs never see each other: Two bulbs may not share a row or column unless a wall sits between them.
- Numbered walls: A number on a wall says how many bulbs touch it on its four sides.
- Plain walls: Walls without a number can have any number of bulbs next to them.
