Tetris Classic

Tetris: Pieces fall randomly across the playing area. The object of Tetris is to move these pieces left and right or rotate them 90 degrees to form a horizontal line of pieces with no gaps in it. If such a line is formed, it will disappear and all the pieces above that line will fall. The more lines that can disappear together, the more points you get. As the Tetris game progresses, the movement of the pieces becomes faster and the game ends when the accumulated pieces reach the top of the playing area.
