All the white cells must be connected horizontally or vertically.
A cell with a number can be blacken. Two black cells must not be orthogonally adjacent.
The number in a white cell indicates the number of orthogonally adjacent black cells.
The number in a black cell indicates the number of diagonally adjacent black cells.
The puzzle involves logically placing black cells within a grid based on numerical clues that represent the number of adjacent black cells. The placement of black cells must ensure that all white areas remain connected and that no two black cells are placed directly next to each other.
