Tetris

Alexey Leonidovich Pajitnov is a Russian computer engineer, currently residing in the United States, who developed the popular game Tetris while working for the Computing Center of the Soviet Academy of Sciences, a Soviet government-founded R&D center. Despite being the developer of Tetris, Pajitnov did not receive royalties from his creation, as rights were owned by his employer, the Soviet government, which distributed it throughout the... USSR and Eastern Europe. He only started to get royalties from his creation by 1996 when he and Henk Rogers formed The Tetris Company. Alexey Pajitnov created Tetris with the help of Dmitry Pavlovsky and Vadim Gerasimov in 1985. The game, first available in the Soviet Union, appeared in the West in 1986. Pajitnov also created the lesser known sequel to Tetris, entitled Welltris, which has the same principle but in a three dimensional environment where you see the "board" from above.
