Tetris

Various shaped groups of blocks will drop from the top/center of the play field. You will need to move the shapes left or right or rotate them to get them to fit as they drop. Once you have decided the position of the shapes you may hit the down arrow key to drop it quickly. Whenever an entire row of 10 blocks has been filled they will disappear, dropping everything above down, and award the appropriate points based on the color of each block. The game will continue until no additional shapes can be dropped, however, every 60 seconds for the first 9 minutes the game speed will increase slightly.
