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.

By 2020, Saelee had hypertapped his way to a Level 35 performance, while fellow player EricICX had achieved the first Level 38 performance.
