Nuri Nearest Number
Shade cells so the white board stays connected and numbers show distances.
Controls
Shade some cells so that shaded cells never share an edge and all unshaded cells stay orthogonally connected. A number cannot be shaded; it gives the distance through unshaded cells to the nearest other number. Tap a cell to cycle empty → shaded → white, then use Clear and the answer button.
