 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.
