This puzzle is one of the ones that I used as a sample puzzle in my Survey of Paint-by-Number Puzzle Solvers as an example of a larger, more difficult puzzle that still has a unique solution. It's an interesting puzzle from a programmer's point of view because some solving strategies that work well on other hard puzzles completely collapse on this one.#10: Adam Nielson (monkeyboy) on Nov 10, 2009I wonder if Adam would be willing to give permission to allow this puzzle to be freely redistributed as part of a standard test set for developers of new solving programs.
Sure, why not.#11: bugaboo (bugaboo) on Jan 30, 2011

Thanks for the wonderful comment. If you like difficult puzzles, check out my puzzle # 7604. I believe it is the most difficult puzzle (of those that are completely line logic solveable) on this site. Enjoy!#16: Vaggelis Kamaris (evag7651) on Aug 7, 2017
