The puzzle is to disentangle the two metal “M”s.
To this day Brian @ Mr Puzzle still considers this to be one of the best disentanglement puzzles in his collection. Only bettered by the MMM puzzle which has 3 M pieces joined together!
Each time he revisits the puzzle after not having played for a long time is like solving it from scratch all over again.
The MM puzzle has become one of the most recognisable puzzles around. Probably because it’s so much fun to fiddle with, even if you can’t solve it! It’s been called many other names, The Devil’s Claw, Twin Tangle, Hanayama Devil, The Double M puzzle, The Double W puzzle or The MW puzzle to name just a few. It’s so good that even Hanayama make a version of it now called Devil but we prefer to sell this larger version; better to handle and not so fiddly as some of the smaller ones.
Until recently we didn’t really have any information about the origins of the puzzle; that was until we visited with Nanco Bordewijk in Amsterdam after the International Puzzle Party in Paris in August 2017.
Nanco was the one who was instrumental in introducing puzzle collectors to the MM puzzle back in 1993 when he gave a puzzle he called “The Sao-Paulo Puzzle” as his exchange gift at the IPP13 event held in Breukelen in The Netherlands in August of that year. Nanco told us that a pilot friend of his had bought him the puzzle after a trip to Sao-Paulo, Brazil. There was no information with the puzzle and the designer of the puzzle was not known. Nanco and his friend tried many times but unsuccessfully to find the designer and so the person remains unknown to this day.
So despite many people and even large manufacturers having claimed this puzzle as their own unless they are from Brazil it’s very unlikely that is the case.
Size: Each M is 60mm x 55mm using 5mm metal.
