cse-ahsankhan/Tetris

Tetris (Russian: Тетрис [ˈtɛtrʲɪs]; portmanteau of "tetromino" and "tennis") is a tile-matching puzzle video game originally designed and programmed by Soviet Russian software engineer Alexey Leonidovich Pajitnov (Russian: Алексе́й Леони́дович Па́житнов).[1] The first playable version was completed on June 6, 1984,[2] while he was working for the Dorodnitsyn Computing Centre of the Academy of Science of the Soviet Union in Moscow.[3] He derived its name from combining the Greek numerical prefix tetra- (the falling pieces contain 4 segments) and tennis, Pajitnov's favorite sport.[4][5] The name is also used in-game to refer to the play where four lines are cleared at once.
