The puzzle is to get the beads on the same loop, on the same side of the wood.
A puzzle called The Block and Tackle was designed by combining the design of a puzzle which had been played in Europe (published as early as 1735) and North Africa for centuries, and the Sleeper Stopper designed by Stewart Coffin in 1972.
Over the years this puzzle has been used widely as a marketing gift. Cohn's Pharmacy of Camberwell, Victoria, Australia used it to advertise their business in the early 1900s and even to this day Mr Puzzle has used variations of this one for corporate gifts.
