What is It?
- A contest where you place light bulbs on the grid such that every white square is lit.
- A number in a square indicates how many bulbs share an edge (but not diagonally) with that square.
- A square is lit if it's in the same row or column as a bulb, as long as there are no Black blocks between them.
- No bulb may light another bulb.(if a light bulb is already on that row or column you can not place another bulb, unless there is a black square in the way).
