Tetris

Tetris (Russian: Тетрис [ˈtɛtrʲɪs]) is a tile-matching video game created by Russian software engineer Alexey Pajitnov in 1984. It has been published by several companies, most prominently during a dispute over the appropriation of the rights in the late 1980s. After a significant period of publication by Nintendo, the rights reverted to Pajitnov in 1996, who co-founded The Tetris Company with Henk Rogers to manage licensing.
