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”.

Release notes:

Added some SFX. When a line clears. Also, in 1-player mode, once the level changes, the little song from the GB version of Tetris will play. Please please please test this on real hardware, someone!
