Not all of the puzzles you will view on this page will have solution links.
I reserved that choice to those that appear to be the most challenging in the high difficulty rating.

As much as I admire Puzzlemaster for their achievement of visual creativity, and have the greatest respect for their resourcefulness in creating the solutions for this line, there are those few instances where certain of their
solutions may appear ambiguous to the less initiated .

I admit that I myself have been challenged from the confusion resulting from failure to
understand some of their schematics.

So, to that end, I've enhanced some of the original solutions to better acquaint the viewer with a more familiar understanding of what they are trying to achieve visually.

Let me remind the reader here that there are but a very select few of these not-so-familiar solutions.

cast NEWS

According to the description on PuzzleMaster's  webpage  for this puzzle, "I came up with the idea for this puzzle when I was 19 years old. It just came to me during a stroll home in the snow; it's truly a creation of my youth. Unfortunately, saying anything here about its construction would give away how to solve it. I certainly can't disappoint the fans that have come to expect frustratingly difficult puzzles from me. Besides, the fans that refuse to accept any kind of hint are those who make me the happiest! The key word is 'needle'."
