Alexey Leonidovich Pajitnov (born 14 March 1956) is a Russian video game designer and computer engineer who developed Tetris while working for the Dorodnitsyn Computing Centre of the Soviet Academy of Sciences, a Soviet government-founded R&D center. He only started to get royalties from his creation in 1996 when he and Henk Rogers formed The Tetris Company.
Tetris was the first entertainment software to be exported from the Soviet Union to the US, where it was published by Spectrum HoloByte for Commodore 64 and IBM PC. Tetris is a popular use of tetrominoes, the four-element special case of polyominoes. Polyominoes have been used in popular puzzles since at least 1907, and the name was given by the mathematician Solomon W. Golomb in 1953.
The game, or one of its many variants, is available for nearly every video game console and computer operating system, as well as on devices such as graphing calculators, mobile phones, portable media players, PDAs, Network music players and as an Easter egg on non-media products like oscilloscopes. It has inspired Tetris serving dishes and been played on the sides of various buildings.
While versions of Tetris were sold for a range of 1980s home computer platforms as well as arcades, it was the successful handheld version for the Game Boy launched in 1989 that established the game as one of the most popular. Electronic Gaming Monthly's 100th issue had Tetris in first place as "Greatest Game of All Time". In 2007, Tetris came in second place in IGN's "100 Greatest Video Games of All Time". In January 2010, it was announced that the Tetris franchise had sold more than 170 million copies, approximately 70 million physical copies and over 100 million copies for cell phones, making it the best selling paid-downloaded game of all time.
