Meanwhile, two of Maxwell's companies - the British Mirrorsoft and the American Spectrum Holobyte - were releasing their version of Tetris. The Russians refused to sell Stein the rights to Tetris on his terms. A few months after the deal, Stein came to negotiate the purchase of rights from the real right holders. Stein sold the rights to Tetris to Mirrorsoft (and its subsidiary Spectrum HoloByte), owned by British media mogul Robert Maxwell. Robert Stein immediately decided that the game could be published freely. For some reason unknown to Stein, Pazhitnov gave him Tetris.
Stein went to Moscow, where he met with Alexei Pazhitnov, and agreed on a license to release the game. A few months later, the importer of software from Hungary - Robert Stein - heard about the game. The game quickly spread through Moscow and further around the world. 7 "tetromino bricks" Tetris: I, J, L, O, S, T, Z.įor IBM PC, the game was rewritten on Turbo Pascal by 16-year-old schoolboy Vadim Gerasimov.
The main idea of "Tetris" was born in those experiments - the figures fall and the filled rows disappear.
However, there was not enough computing power for the rotation of the pentomino, it was necessary to debug on tetromino, which determined the name of the game. Pazhitnov tried to automate the fitting of pentomino in the given figures. Working in the Central Committee of the USSR Academy of Sciences, Pazhitnov dealt with the problems of artificial intelligence and speech recognition, and used puzzles, including the classic pentomino to test ideas. ‘Tetris’ was written by Alexei Pazhitnov in June 1984 on a computer ‘Electronics-60’. In particular, pentominoes were so popular that in the "Science and Life" since the 1960s there was a permanent column devoted to the assembly of figures from a set of pentominoes, and plastic sets of pentominoes were sometimes sold in stores. Interest in the figures of dominoes, trimino, tetromino and pentomino in the USSR was arisen due to the book by SV Golomb "Polimino" (publishing house "Mir", 1975). The name of the game comes from the number of cells that make up each figure. The idea of "Tetris" was prompted by the pentomino game he bought. Tetris is a computer game invented in the USSR by Alexei Pazhitnov and presented to the public on June 6, 1984.
