Rubik's Cube: interesting facts about the famous puzzle
The puzzle “Rubik's Cube” (“Magic Cube”, “Hungarian Cube” and even just “Rubik”) attracted the attention, as they say, of “all population groups” and gained widespread distribution. We have already written about the merits of this wonderful puzzle, which both schoolchildren and academics began to play with pleasure, finding in it virtues that are consistent with the level of scholarship, education and a penchant for research ( see Science and Life No. 3, 1981 and No. 2, 1982 ) and even cited solution methods.

In the 70s of the last century, the architect Ernё Rubik taught at the Academy of Applied Arts and Crafts of Budapest. There he planned to construct a simple and at the same time fascinating manual for the development of spatial imagination among his students. Rubik made a cube of 27 parts, the components of which could freely rotate without violating the integrity of the structure. The author spent about a month on the first assembly of the resulting puzzle. An unusual cube was liked by his friends and colleagues, and a year later Erneu patented his invention.
In 1982, the first official Rubik's Cube World Cup was held in Budapest. It was won by a student from Los Angeles, Minh Thai, who figured out the puzzle in 22.95 seconds. Later, a special term appeared for those who collect a cube for speed - they began to call them speedcubers. The record for modern speedcubers is 5.55 seconds. In the Soviet Union, the Rubik's Cube appeared in 1981. According to unofficial data, the license for the production and sale of puzzles cost the USSR three million dollars.
