Kurodoko


Translate this site.

Kurodoko also known as Kuromasu is a logic puzzle with simple rules and challenging solutions.

The rules are simple.
Shade some cells black guided by number clues.

- Each number clue shows how many cells are "visible" from its place.
- "Visible" are all white cells up, down, left and right of the clue, terminated by a black cell or the grid edge. The cell with the number clue is also counted as visible.
- Other clue cells are considered transparent, so visibility continues through them.
- You can't shade clue cells black.
- All white cells must be connected orthogonally in a single group.
- Black cells can't touch orthogonally (diagonal touching is allowed).

Left click on a cell to make it black. Right click to mark with a dot. Click and drag to mark more than one cell.
