Nob Yoshigahara Puzzle Design Competition is an annual award and competition in the engineering and design of mechanical puzzles. The location of the competition rotates between North America, Europe, and Japan. It was founded in 2001, and has been known since 2005 as the Nob Yoshigahara Puzzle Design Competition, after the renowned puzzler Nob Yoshigahara.[1][2]
The competition is held in conjunction with International Puzzle Parties founded by Jerry Slocum in 1978, an event dedicated to discussing, showing, and trading of mechanical puzzles.[3] Due to the postponement of the 2020 International Puzzle Party as a result of the COVID-19 pandemic the 2020 competition was held online only and not in conjunction with the puzzle party event.[4]
