Brief intruduction of Chinese Ring Puzzle:
Nine Rings Puzzle is a very classical and well-known Chinese metal puzzles, the puzzle consists of a looped handle interlocked with nine rings. The object is to remove the nine rings from the handle. It will take 341 moves to work out the puzzle but there's a method and once you know it you'll certainly be able to solve the puzzle.
The Puzzle has been analysed by many mathematicians and more recently computer scientists alike. It is particularly interesting because it's has been shown the process of removing the rings can be directly related to binary numbers.
Known around the world as the Chinese Ring Puzzle, or just the Chinese Rings, it's real name is Jiulianhuan but over the years it's also has been known as Nine Linked Ring, The Linked Rings, Chinese Folk Rings, Devil's Needle and more... In France they call it Baguenaudier, in Italy it's known as Anelli di Cardano or Cardano's Rings.
Perhaps China's most famous puzzle ever, certainly equally as well known as the Tangram puzzle, Stewart Culin (an American ethnographer 1858-1929) proved the Chinese Ring Puzzle was invented by the Chinese general Hung Ming in the 2nd century AD.
