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.

Like the name implies, a hypertapping player simply presses left or right on the NES d-pad their desired number of times.
