Range Puzzles

I have always liked puzzles. I really enjoy discovering a new puzzle. Sometimes when I have discovered a new puzzle, I enjoy it so much that I can't seem to do enough of them. In such cases, I quickly run out of these puzzles to do and find myself looking for either a new puzzle or a way to generate them on my own.

Such was the case when I discovered the "Range Puzzles". The rules are simple:

  • Every cell is marked either blue or gray
  • No two gray cells can be next to one another
  • The grid must be a connected (i.e. there is always a path from every cell to every other cell using horizontal and vertical connections.
  • Some cells have a number inside. This indicates the number of cells that can be viewed (horizontally and vertically in both directions) by this cell, including the cell itself.
