Uwe Mèffert (born 28 November 1939)[citation needed] has manufactured
and sold mechanical puzzles in the style of
Rubik's Cube
Rubik's Cube since the
original Cube craze. His first design was the
Pyraminx
Pyraminx and others
include the Megaminx,
Skewb
Skewb and
Skewb
Skewb Diamond.[citation needed] More
recently he has licensed and re-released designs from other
manufacturers, such as Dogic.[citation needed]
In the 1970s Mèffert created some puzzles for his own amusement using
pieces of balsa wood attached to a center ball by rubber
bands.[citation needed] He did not think anyone else would be
interested in them, and put them away and forgot about them until
Ernő Rubik's
Rubik's Cube
Rubik's Cube became a worldwide sensation in the 1980s.
In 1981 Mèffert took his puzzles to a Japanese toymaker who agreed to
market them. One of them, Pyraminx, sold more than 10 million pieces
that year, and 90 million within three years.[citation needed] Since
that time, Mèffert and his associates have created more than 100 3-D
rotating mechanical puzzles.[citation needed]
Mèffert also created his own version of sudoku, the popular
nine-number print puzzle. His puzzle consists of nine 3×3 grids,
“representing total logic.” One has to place the numerals 1 to 9
in each horizontal and vertical row, each 3×3 box and the two major
diagonals without repeating numbers. A “Chinese Magic Square”,
consisting of the numbers 1–9, is hidden in a 3×3 grid somewhere in
each puzzle. Adding any three numbers together in any direction always
adds up to 15, providing additional challenge. Mèffert calls his
version of the puzzle KOKONOTSU, a Japanese word meaning simply
nine.[citation needed]
Mèffert has also produced puzzle designs by Tony Fisher, including
the Golden Cube,[1] and Oskar van Deventer, including the Gear Cube.
