Instruction:
Shade some cells black (leaving the other cells white) so that the grid is divided into black and white regions. (Cells of the same color are considered in the same region if they are adjacent horizontally or vertically.) Each given number must be in a white region that has the same area in cells as that number. Each white region must have exactly one given number. (There is no constraint on the number, size, or shape of black regions.)
