Chinese Nine Linked Rings Puzzle/ Chinese Rings (jiulianhuan) : The nine linked rings puzzle (jiulianhuan ???)?also called Chinese rings?is perhaps China?s greatest mechanical puzzle. Long analyzed by mathematicians?and, now, also by computer scientists?the puzzle consists of a looped handle that is Chinese nine linked rings puzzleinterlocked with nine rings. The objective is to remove all nine rings from the loop, and the solution takes 341 moves, so lots of patience is required. But there?s a method to the solution?and once one learns to solve the puzzle, it?s hard to forget! There is a story that the great politician and strategist Zhuge Liang (181-234)?also known as Kong Ming?invented the nine linked rings for his wife so that she could forget her sorrow in attempting to solve it while he was away at war. And many sources state that the nine linked rings dates back to the Song dynasty (960-1129), but there doesn?t appear to be any documentary evidence to prove this. So the truth is that nobody really knows who made the first nine linked rings puzzle or when it first appeared in China. The earliest known Western description of a puzzle of this type is by the Italian mathematician Luca Pacioli (1445-1517), who was a friend of Leonardo da Vinci. This appeared in Pacioli?s manuscript De Veribus Quantitatis, written around 1500.
