Rules: Shade some empty cells black so that the grid is divided into orthogonally connected white regions. Each white region must contain exactly one given number, which must be equal to the area (in cells) of that region. The black cells must be orthogonally connected, but no 2x2 group of cells can be entirely shaded.
