Black out some of the squares, in such a way that:

  • no number appears twice in any row or column
  • no two black squares share an edge
  • the white squares form a single connected group through their edges

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.
