Erno Rubik was teaching interior design and architecture in Budapest when he created what is now
known as the Rubik's Cube. Rubik studied architecture and design at the Academy of Applied Arts and Crafts in the late 1960s.
He took a job as an instructor there, and in his free-time he built models and worked on the three-dimensional designs. The
first working prototype of his cube was finished in 1974, and he applied for a Hungarian patent on the design in early 1975.
The puzzle is a cube made up of smaller, colored interlocking cubes (3 x 3 x 3) that can be scrambled by twisting the
horizontaly and verticaly. In it's first form, the cube's six faces -- made up of nine squares -- are colored yellow,
white, orange, blue, red and green. Once the cube has been twisted, getting the parts arranged back to the first form
is not so easy. It was not intended for it, but it took Rubik a month to solve his own puzzle. By 1977 his "magic cube" was
being manufactured in Hungary, and its first burst of popularity was in Europe, despite the lack of a marketing or advertising
campaign. By 1980 it had been introduced to the United States and the rest of the world. The toy sold by the millions and
attracted the attention of many in the academic community; it also became a competive event in 1982, when Budapest hosted
the first world championship. Although the craze lasted only a few years, the Rubik's Cube is now a toy store standard and
has started dozens of imitations and "spin-offs." Rubik became one of Hungary's richest inventors and went on to develop
more games and puzzles, including his more famous cube, Rubik's Revenge (a 4 x 4 x 4 cube)
