Hypertapper

David ‘aGameScout’ MacDonald, one of the top content creators in the community, agrees with Cheez. “Eventually I would think almost all the top players in the scene will be rollers of some kind. There is a building sentiment among the top hypertappers now that they need to learn rolling to keep up.”

Joseph Saelee, the first hypertapper to win the championship, holds the controller against his leg and primarily uses his right thumb to hypertap and his middle finger to rotate the pieces, meaning his hand rests above the rectangular controller more like he's typing on a keyboard than holding it in a traditional way. […] His success, and young age, only 16 when winning his first championship, inspired a new generation to take up Tetris, and within a few years dozens of young hypertappers were competing at a high level.

While that gives a little breathing room, a run of bad pieces or execution can still put a hypertapper in an untenable position where the pieces start to stack up high, and completing new lines becomes essentially impossible.
