The puzzle is to build the 12 pointed star from the six identical pieces.
The puzzle has a long history and there’s some evidence that a version of the six piece diagonal burr was known as long ago as 1875 but a formal patent No 779121 was definitely granted in St. Louis, Missouri, USA on 3rd January 1905 to George R. Ford who said he had invented the puzzle. He stated “My invention relates to a puzzle consisting of a plurality of polygonal-shaped blocks that are designed to be placed together in pairs, each block being provided with a pair of notches to receive a pair of blocks adjacent thereto and having intermediate of its notches a tapering four-sided portion that fits between an adjacent pair of blocks.”
Nowadays it is often called The Cluster because of the star-like cluster of wooden blocks making this puzzle. It has also been sold commercially using other names – all suggesting it’s striking shape – Gem Cut Puzzle, Chestnut Burr & The Snowflake.
The puzzle is made from blonde wood and finished in clear acrylic.
Size of the puzzles is: 75mm x 75mm x 75mm (each piece 75mm x 25mm x 25mm)
