The objective is to divide the grid into shaded and unshaded cells, subject to the following rules:

  1. Each region contains one number with an area equal to that number.
  2. Numbers in white cells are part of white regions; numbers in gray cells are part of gray regions.
  3. Same colored regions cannot share an edge.
