Scrabble evolves constantly along with language, with new words keeping the game from ever becoming stale. With SO many words already in the dictionary, though, it's rare that any individual word makes that much of an impact. In 2006, one word proved to be a huge exception to this rule the Chinese life force QI.

(Note that QI was already valid in the Collins lexicon used outside of North America at that point in time, but the majority of the video is still relevant)

Thank you to:

Josh Castellano for helping find great preQI example games
