Possibly dating from around 1900. We do not know who invented this intriguing puzzle or who manufactured it.

It poses some interesting challenges.


The "Disko Puzzle" was acquired from the John Ergatoudis Collection; but unfortunately it was missing 3 of the 21 discs that it should have contained. We posed a challenge to attendees at IPP31 in August 2011. Nobody has provided a satisfactory solution it so we have decided to open the competition to everyone.

Your challenge is to discover the size of the missing discs and the number that should be printed on each, and send us a solution to the puzzle.

There may be several solutions, in which case we will take the number and elegance of solutions into account when selecting the winner.

Cheating is permitted; so if you can find another example of this puzzle you will be half-way to the answer.

The prize will be an antique "Ne Plus Ultra" Vesta Puzzle with the " 1/6 ME A DOG " puzzle similar to one of those shown on this link.

By the way, the "1/6 me a dog" puzzle still remains unsolved so there is another prize for solving that.
