This puzzle I created for the practice of US Puzzle Championship 2009. In fact this puzzle is a cave puzzle variation. Cave puzzle was the first puzzle which I created in my life. Cave puzzle was also the among the first ones which I published on the blog i.e. I started this blog after posting a Cave puzzle. I will soon re-post that Cave puzzle soon. Currently I am posting this Inside/Outside Corral puzzle as 20th puzzle in Mini Puzzles Series.
Rules of Inside/Outside Corral
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.
