Nuraf , also known as Araf Nurikabe , combines the rules of Nurikabe and Araf. A rectangular or square grid contains numbers in some cells. The goal is to blacken a few cells of the grid or to place a dot according to the following rules:

  • The black cells divide the grid into islands.
  • Cells with numbers are never blue and belong to an island.
  • Two islands are never horizontal or vertical connected.
  • All blue cells must be connected horizontally or vertically.
  • No 2x2 areas can be blue.
  • Each island contains exactly two numbers.
  • The size of an island must be equal to a digit between the 2 digits that are in that island. For example, if the island contains 1 and 4, the size of the island must be 2 or 3 cells.
