I did get a new high score for myself once I realized that oh duh maybe go for Tetrises to maximize the scoring potential before it gets too fast for your slow brain. = p
The young programmer Pajitnov turned to for porting Tetris to MS-DOS, Vadim Gerasimov, has his own account of Tetris, and it's a good read: https://vadim.oversigma.com/Tetris.htm . According to his account, he never received any pay for the game--which they originally did for fun, I suppose--and was persuaded by Pajitnov to sign away any rights to it, oof!
And Pajitnov's friend from his Soviet Academy of Sciences days, Vladimir Pokhilko (here's another thing I had wrong: Pokhilko wasn't at the Academy, he was at the Moscow Medical Institute) https://en.wikipedia.org/wiki/Vladimir_Pokhilko , and who emigrated to the US with Pajitnov in 1991, ended up being squeezed out of Rogers' Tetris business arrangements, and was left with another company the three had founded, AnimaTek, whose employees were still largely in Russia, which was making the financial situation difficult--and in 1998 Pokhilko ended things in a murder-suicide in California. = o
