Shade cells so each white region has one clue counting its black neighbours.

Controls

Shade some cells. Borders and shaded cells divide the unshaded cells into white regions. A white region may contain at most one number, and that number equals the number of shaded cells orthogonally adjacent to the whole region. Numbers cannot be shaded. Tap a cell to cycle empty → shaded → white, then use Clear and the answer button.
