atari2600land has updated his single and two player simultaneous play variant of a very well known Russian block game.

Release notes:

I think I fixed that one. I tried cleaning out four lines and it worked. Also, in this version, you can change the colors from black and white to color (and back and forth) during the game, too, not just the title screen. I don’t know why people haven’t commented on my little surprise if you get 100 lines or more in 1 player A-Type. It’s basically the same thing that happens in Tetris for Game Boy: A rocket launches (only mine says “USA” on it, although we don’t launch rockets any more. How sad…) and the same music from the Game Boy version of Tetris plays. If you spot any bugs, as usual, please let me know.
