In its most basic sense this toy is a series of 6 concentric arches of constantly increasing radius, but, we are dividing each of those arches into an increasing number of segments, starting with the unit at the center, [a semi-circle] then the second arch divided into two equal shapes, the third in three and so on, all the way up to the sixth, divided into six equal pieces.
This is an elegant and logical system to create blocks that can be stacked up in this perfect radial order or you can build pyramids, walls, linear arrangements, and of course develop your own way to play.
Behind this toy, there are ideas of geometry and math and you can explore physical concepts that apply to real-life structures like bridges or arches
It is truly amazing how such a simple idea as dividing the fundamental arches and the resulting curved blocks creates so many possibilities and hours of entertainment.
