A beautiful 7-piece puzzle made in 7 different wood colors. At first sight, this looks like a traditional Tangram set, but when you take a closer look, there’s actually a few key differences. The most important is the inclusion of an irregular quadrilateral which will make it much more challenging than a regular Tangram. Just like its cousin, By the Way can be used to build countless shapes with some already included in the tray and instructions. This Tangram variation was created over 120 years ago, in 1891 more precisely. The modern-day version of this fascinating puzzle was designed by Jürgen Reiche just a couple of years ago.
