Shade cells so each number counts the shaded cells around it.
Controls
Shade some cells. A number gives how many of the up to eight cells around it, including diagonal neighbours, are shaded; the clue cell itself is not counted and may be shaded or left white. Tap a cell to cycle empty → black → white; use Clear to reset and the answer button to reveal or hide the full solution.
