LEV     PUZZEL        

Gappy ("Gaps") is played on a square grid. The goal is to make cells WHITE or BLACK according to the following rules:

  • Each row and column must contain two BLACK cells.
  • BLACK may not touch each other, not even diagonally.
  • Numbers outside the grid show the number of WHITE cells (=GAP) between the BLACK cells in a corresponding row or column.
  • Once you have found the 2 BLACK cells of a row or column you can make all the remaining cells of that row or column WHITE.

First, look for the cells that you are sure to be WHITE. Especially high number clues can help you with that.
