Rubik's Cube: interesting facts about the famous puzzle
The puzzle "Rubik's Cube" ("Magic Cube", "Hungarian Cube" and even just "Rubik") attracted attention, as they say, "of all groups of the population" and received the widest distribution. We have already written about the merits of this remarkable puzzle game, which both schoolchildren and academicians began to play with, finding in it dignity that matches the level of scholarship, education, and inclination to research ( see No. 2, 1982 ) and even cited solution methods.

In the 70s of the last century, architect Erno Rubik taught at the Academy of Applied Arts and Crafts of Budapest. There, he decided to construct a simple and at the same time fascinating manual for the development of spatial imagination of his students. Rubik made a cube of 27 parts, the components of which could rotate freely without disturbing the integrity of the structure. The author spent about a month on the first assembly of the resulting puzzle. An unusual cube fell in love with his friends and colleagues, and a year later Ernö patented his invention.
In 1982, the first official world championship on the Rubik's cube assembly was held in Budapest. It was won by a student from Los Angeles Minh Thai, who dealt with the puzzle in 22.95 seconds. Later, a special term appeared for those who assemble a cube for speed - they began to be called speedcubers. The record of modern speedcooters is 5.55 seconds. In the Soviet Union, the Rubik's cube appeared in 1981. According to unofficial data, a license for the production and sale of a puzzle cost the USSR three million dollars.
