In this post, as an exercise, I will try to summarize the video New NES Tetris Technique: Faster Than Hypertapping!.
In NES Tetris, fast piece movement is essential for the very last levels when the pieces fall really fast. The normal way to move pieces left and right is by holding down left or right on the D pad, but that has a built in delay (known as DAS) before the piece starts moving at the max speed for holding down, which is around 10 Hz. This is similar to holding down a key on a computer keyboard: it takes a while to start repeating the key quickly, and even then, it doesn’t repeat that fast.
If you tap the D pad instead of holding down, the piece moves quickly – for all practical purposes, it moves as fast as you can tap – and without any delay. Until recently, the only known way to tap really quickly in NES Tetris was a technique known as “hypertapping”. To hypertap, you just tap a finger on the D pad really fast. However, hypertapping is strenuous and hard to learn.
In late 2020, a Tetris player called Cheez_Fish discovered a way to apply to NES Tetris an arcade game technique for fast button pressing called “rolling”. Rolling is faster than hypertapping and easier on the hands. Cheez_Fish’s version of rolling works by tapping the back of the controller with multiple fingers. This causes the controller to bounce against his thumb, which he holds steady against the D pad.
In November 2020, Cheez_Fish posted a video of him getting 20+ taps per second with rolling (3:55 in the video). The video says this is “faster than even the fastest hypertappers”. Cheez_Fish soon developed his skill to a level where he could use it in competitions. In March 2021, Cheez_Fish got the first score over 1.3 million and became the first person to get 4 Tetrises on level 29. On April 5, 2021, “Cheez set a new world for highest score on a level 29 start with 259,000 in probably one of the most impressive NES Tetris games of all time.”
Other people have started to learn rolling. The video announcer himself tries it and has a bit of success.
