Robert Stein of Andromeda Software liked the game, they referred him to the Soviet Academy of Science's Computer Center. Because the idea of intellectual property rights did not exist in Soviet Russia, as anything Pajitnov had made belonged to the state, he did not receive even a bonus for his work. They distributed it to their friends, and soon later the game, Pazhitnov would say, "Tetris, in two weeks, was in every single computer in Moscow." It further reached the outskirts of the Soviet Union and eventually throughout Europe. By the summer of 1985, Aleksey distributed the first color version of Tetris to his friends outside the Computer Center. The game quickly made its way through the Computer Center. Pajitnov's friend Vadim Gerasimov would later port this to IBM PC. This first version, which Pazhitnov created using Pascal on the Electronica 60, consisted of brackets and of black and white graphics, with pieces made up of brackets. Also different from pentaminoes, they now fell into a well, where a player would have to arrange in a specific way. After long hours of working on the game (said by coworker Mikhail Kulagin to have "smoked an enormous amount of cigarettes"), Pazhitnov's game of pentaminoes transformed into tetrominoes. Pazhitnov, an enthusiast of puzzle games, shaped his favorite game, pentominoes into his programming. Aleksey Pazhitnov first programmed Tetris while working for the Soviet Academy of Sciences at their Computer Center in Moscow on June 6, 1984.
