Hard, but awesome puzzle. 5 stars for me. That renban line in box 6 was a pain in the neck. Took hours to solve but it was worth it. Thanks for the puzzle.

Fantastic puzzle, got stuck a few times, but thoroughly enjoyed it. I think the renban line dropping into box 9 makes it so much more difficult. Thank you
