I too stumbled upon Classic Tetris through the Youtube algorithm.

I've watched almost all of the 2019 and 2020 world championships and the game is just played so well with so much energy. It's really a simple game and the players are just SO fast at understanding the combinations and when to "burn" lines to set up more valuable Tetrises.

Incredibly surprised that Joesph lost but it was a REALLY REALLY close game (https://www.youtube.com/watch?v=isbvQVngnXA)
