About Uwe Mèffert
- Uwe Mèffert (born 28 November 1939) is a German puzzle designer and inventor.
- He has manufactured and sold mechanical puzzles in the style of Rubik's Cube since the original Cube craze.
- His first design was the Pyraminx(Created before the original Rubik's cube.) and others include the Megaminx, Skewb and Skewb Diamond.
- More recently he has licensed and re-released designs from other manufacturers, such as Dogic.In the 1970s Mèffert created some puzzles for his own amusement using pieces of balsa wood attached to a center ball by rubber bands.
- He did not think anyone else would be interested in them, and put them away and forgot about them until Erno Rubik's 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.
- Since that time, Mèffert and his associates have created more than 100 3D rotating mechanical puzzles.Mèffert also created his own version of sudoku, the popular nine-number print puzzle.
- In addition to the standard sudoku rules, the two major diagonals must also contain the numerals from 1 to 9.
- Additionally, a Chinese magic square is hidden somewhere in the solution.
- He named this puzzle Kokonotsu, Japanese for nine.Mèffert has also produced puzzle designs by Tony Fisher, including the Golden Cube, and Oskar van Deventer, including the Gear Cube.
