Nob Yoshigahara came up with the idea for this puzzle when he was 19 years old. It just came to him during a stroll home in the snow, truly a creation of my youth.
Unfortunately, saying anything here about its construction would give away how to solve it. He 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 him the happiest!
The key word is “needle.”
