More than years ago, this game was as famous as the Rubik cube and has been played passionately by many as entertainment, educational or mathematical tool, because it boosts shape recognition, problem solving, and pattern design skills.

The PVC before compounding can be thought of as similar to flour, by adding various ingredients flour can be used to make for bread, cakes or many other items but on its own the flour is useless.

In his book, "Art and Geometry: Piece 7, or "P": This, no doubt, was due to the opening up of trade with China and the aforementioned sailors bringing home new found amusements.
