The puzzle is to build the 12 pointed star from the six identical pieces.
A patent was approved for this puzzle in St. Louis, Missouri, USA to inventor George R. Ford. Patent No 779121 on 3rd January 1905. However there is some evidence that a very similar puzzle had been documented as early as 1875.
George R. Ford claimed: “I claim as my invention – A puzzle consisting of a plurality of blocks 70 all of which are identical in form and shape, each of said blocks being provided with pairs of notches and a four-sided tapering portion between said notches; said blocks being adapt- ed to be placed together in pairs to occupy 7 5 notches in adjacent blocks and have their foursided tapering portions arranged in mating facing positions, substantially as set forth.”
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.
Mr. Puzzle has not changed the puzzle but perhaps his name for it is more appropriate!
