Tetris (Russian: Тетрис [ˈtɛtrʲɪs]; portmanteau of "tetromino" and "tennis") is a tile-matching puzzle video game originally designed and programmed by Soviet Russian game designer Alexey Leonidovich Pajitnov (Russian: Алексе́й Леони́дович Па́житнов). The first playable version was completed on June 6, 1984, while he was working for the Dorodnitsyn Computing Centre of the Academy of Science of the Soviet Union in Moscow. He derived its name from the Greek numerical prefix tetra- (all of the game's pieces contain four segments) and tennis, Pajitnov's favorite sport. The name is also used in-game to refer to the play where four lines are cleared at once.
