How to play

  1. A number counts the white cells it sees up, down, left and right, including itself. Black cells block the view.
  2. Black cells never share an edge. Numbered cells stay white.
  3. Every white cell joins one connected area.

Controls

Tap to shade, tap again to mark white, again to clear. Arrows move; B shades, X marks white.
