Each player receives an individual board which they try to fill up with Tetris tiles. These are taken blindly in real time. Pieces must be played from the bottom up, as in the video game. Unwanted pieces can be given to opponents, who must play them. The object is to have the fewest open spaces on one's board when the game ends. This should not be confused with the Tomy Tetris or Tetris Tower 3D.
