About Kurodoku Puzzles
Kurodoku (also called Kuromasu) is a Japanese shading puzzle. Each number tells you how many white cells it can see along its row and column, counting itself, until the view is blocked by a black cell or the edge of the grid.
How to solve Kurodoku
- Visibility numbers: A number counts the white cells visible up, down, left and right, including its own cell.
- Numbers stay white: A cell with a number is never shaded.
- No touching black cells: Two black cells may not share an edge.
- One white area: All white cells must connect into a single group.
Reading the sheet
- Shaded cells in the answer key are the black cells.
