Draw a single closed loop along the grid lines. If a number is inside the loop then it equals the count of interior squares that are directly in line (horizontally and vertically) with that number's square, including the square itself. Similarly, if a number is outside the loop then it equals the count of exterior squares that are directly in line with that number's square, including the square itself.
