Although this may appear to be the classic Tower of Hanoi, Jean-Claude Constantin has raised the order of the puzzle - more pieces means that the puzzle is more difficult.

Made in several attractive woods by Jean-Claude Constantin. Jean-Claude Constantin lives in Germany, where he designs and manufactures many different wood and metal puzzles, as well as magic tricks and other intellectual toys and games.
