atari2600land has updated his single and two player simultaneous play variant of a very well known russian block game. The game was previously known as “Tetris”.

Changes::

+When you try to rotate a piece and it can’t rotate, the rotating sound is gone.
+Added a little music to the secret scene (you’ll see it if you get 100 lines or more.)
