- A 4 black cell requires bulbs on all four sides.
- A bulb placed on a cell lights its entire row and column until a wall.
- Look for white cells that can only be lit from one direction.
- Never place two bulbs where they would see each other.
- Use the constraint that every white cell needs light to find forced placements.
