Much has been said about the historicity of Tetris and its many iterations, but I find the very original text-based graphics version from 1984 to be the most charming. If I was committed to grinding this as a pseudo-sport, to improve my logic center and simple problem-solving speed, I'd likely opt for one of the later titles, probably Tetris 2000 or something based off of that for what little I know; but I don't really care to, it's just an extremely fundamentally well-made puzzle game with a background that frequently births inspiration. Bored, and a few lines of code later... Tetris!

You can play a recreation of this 1984 original here,, as well as Tetris Holdings' tribute to the original. I prefer the presentation of the first here, but the second is good too.
