Rubik's Cube How the puzzle achieved success Emo Rubik first studied sculpture and then later architecture in Budapest, where he went on to become a teacher of interior design. It was whilo he was working as a teacher that he began the preliminary work on an invontion that he called the Magic Cubo' Rubik was inspired by goometric puzzles such as the Chinese langram, a puzzle consisting of various triangles, a square and a parallelogram which can be combined to create different shapes and figures. However, unlike the tangram, which is two. dimensional, Rubik was more interested in investigating how three-dimensional forms, such as the cube, could be moved and combined to produce other forms. His design consisted of a cube made up of layers of individual smaller cubes, and each smaller cube could be turned in any direction except diagonally. To ensure that the cubes could move indopendontly, without falling apart, Rubik first attempted to join them together using elastic bands. However, this proved to be impossible, so Rubik then assembling them using a rounded interionived of to move smoothly and easily. He experimented ways of marking the smaller cubes but ended simple solution of giving a different colour to dulf object was to twist the layers of small cubes eag of the large cube was an identical colour. Rubik took out a patent for the Cube in 1977 and manufacturing it in the same year. The Cube came attention of a Hungarian businessman demonstrated it at the Nuremberg Toy Fair. When expert Tom Kremer saw it, he thought it was ama persuaded a manufacturer, Ideal Toys, to produc of them in 1979, Idea Toys renamed the Cube as inventor, and in 1980 Rubik's Cube was shown over the world. It won that year's prize in German Puzzle. Rubik's Cube is believed to be the world c puzzle; since its invention more than 300 millions r been sold worldwide.
