Fit all the pieces into the frame.
This wooden packing puzzle is appropriately named as it befits the style of the classic artist, Mondrian. The challenge is to fit all the pieces into the frame. The elements include rectangular pieces of various sizes, as well as border sections that must all fit together. A very difficult packing puzzle challenge! 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.
