Every year there is a Classic Tetris World Championship where people from around the world compete in a NES Tetris tournament. Things have gotten ridiculous with the skill level.
The 29th level in the game is when the already accelerated game speed gets doubled. It is supposed to be unplayable and was referred to as the "kill screen" all the way up to just a couple years ago. The best in the world didn't really play far into the kill screen.
But these kids have figured out how to "roll" their fingers against the back of the controller while using their thumb on the DPAD to force the pieces to move further/faster than ever possible before.
So the physical manipulation of the controller plus a smart kid's brain obsessing over NES Tetris strategy has led to an all new level of skill. It used to be mostly 30-50 year old dudes but now it's all early teenage kids. But seriously just watch the first game of this match:
