hypertapping

It wasn’t until 2018, after a young player won a prestigious competition using hypertapping, that more players starting using it.

Prior to this, DAS and Hypertapping were the two standards for Tetris pros, but Rolling allows for a high amount of button presses per second without the "superhuman finger speeds" needed for Hypertapping, modified controllers, or any gloves - which also makes it is perfectly legal for tournament play.

The strategy that has dominated recently for the last couple of years is to tap the d-pad as fast as humanly possible with one finger, known as hypertapping in the gaming community. In NES Tetris, this skill is crucial, since the speed increases when moving up levels, culminating in level 29, where the pieces usually drop to the bottom of the board in less than ⅓ of a second. However, hypertapping has several limitations.

The first known way past the brick wall of Level 29 was a technique that became known as hypertapping. By using a special grip that lets you vibrate a finger over the D-pad directions at least 10 times a second, you can effectively skip the "delayed autoshift" (DAS) that limits how fast pieces can move laterally when the D-pad is held down.
