An oddly-shaped disentanglement puzzle designed by Siebenstein-Spiele founder Jürgen Reiche. In order to solve the puzzle, one must remove the metal ring. Instead of the normal pieces of square or round wood, this puzzle features an unusually-shaped oblong piece of wood with an ovaloid hole. Made in laser-cut and turned wood, rope, and stainless steel by Siebenstein-Spiele. Based in Munster, Germany, Siebenstein-Spiele was founded in 1992. Although the company is mainly known for board games, Siebenstein-Spiele also makes many wooden puzzles, several of which have been designed by company founder Jürgen Reiche.
