Black out some of the squares, in such a way that:
- no number appears twice in any row or column
- no two black squares are adjacent
- the white squares form a single connected group (connections
along diagonals do not count).
Click in a square to black it out, and again to uncover it.
Right-click in a square to mark it with a circle, indicating that
you're sure it should not be blacked out.
