TETRIS is a puzzle video game originally designed and programmed by Alexey Pajitnov in June 1985,while working for the Dorodnicyn Computing Centre of the Academy of Science of the USSR in Moscow.A random sequence of tetrominoes fall down the playing field.The object of the game is to manipulate these tetrominoes,by moving each one sideways and rotating it by 90 degree units,with the aim of creating a horizontal line of blocks without gaps.When such a line is created,it disappears and any block above the deleted line will fall.Tetris was first published by Tengen for NES but because of the copyright of Nintendo,they were all collected back and Nintendo released their own version which was licensed from Alexey Pajitnov...
