Classic Tetris Version 1 descriptions Classic Tetris is a very popular falling blocks puzzle game. A sequence of tetrominoes - shapes composed of four circle blocks each - fall down the playing field. The object of the game is to manipulate these tetrominoes by moving each one sideways & 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 & the blocks above fall. As the game progresses the tetrominoes fall faster & the game ends when the player "tops out" that is when the stack of tetrominoes reaches the top of the playing field & no new tetrominoes are able to enter. Features: Retro style Boss key Good-looking interface Photo background Nine difficult levels.
