UWE MèFFERT (born 28 November 1939) has manufactured and sold mechanical puzzles in the style of Rubik\'s Cube since the original Cube craze. His first design was the Pyraminx

and others include the Megaminx

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 Ernő 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 3-D rotating mechanical puzzles.

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.

Mèffert has also produced puzzle designs by Tony Fisher , including the Golden Cube, and Oskar van Deventer , including the Gear Cube.
