This puzzle I created for the 10th 24-hour Puzzle Championship. There was a time in the year 2009 when the Oguz Atay Puzzle Contest (OAPC) was conducted. In this championship, many new types of puzzles were introduced. These puzzles later also appeared in the World Puzzle Championship, which was held in Turkey. The range puzzle is also one of the new puzzle variations that appeared during that time. I created a couple of puzzles of this type, which are published on this website.
The Rules of the Range Puzzle
Place digits 1-N in the grid so that no digit is repeated within a row/column. Numbers in the diagram indicate the difference between the biggest and smallest digit in the visible cells. A digit can see others until its view is blocked by a triangular cell. If there is only one cell in sight, the number indicates the digit itself. No cell may remain empty.
