Publisher's Synopsis
Kuromasu (from Japanese "kuromasu wa doko da", literally "Where is Black Cells?"; also known as "Kurodoko") is played on a rectangular grid.
Some of these cells have numbers in them.
Each cell may be either black or white.
The object is to determine what type each cell is.
Numbered cells may not be black.
No two black cells may be horizontally or vertically adjacent.
All the white cells must be connected horizontally or vertically.
