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:

Was test-playing this and kept finding a bug which made the game freeze sometimes if you’re on level 9. So I just removed level 9 altogether. Now if you get 80 blocks, that’s the fastest speed there is. And it’s still pretty hard on that speed (at least for me.)
