Modern Times 21 - 9 Series

A very difficult color-matching puzzle. The objective is to align the wheels or gears so that each one has a common touching color.  Each wheel is made so that it has small sections that have no cogs (teeth), which affects the way that each rotates relative to the others.   This puzzle has more wheels or gear than the 4 series versions, or the 6 series version, which makes it the most difficult in the series. Made with color anodized metal pieces and a decorative border.

Made in laser-cut wood, acrylic, and stainless steel 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.
