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.
