According to Distractify’s own Amber Garrett (who competed on the show in 2016), the answer is no. Amber says that “truly, the best way to prep is to watch the show and study past games. A site called J! Archive has literally every question played over the last 38 years.”
Amber adds that “there are definitely categories of general knowledge that come up frequently and are worth studying up on. In geography, it’s wise to learn all the U.S. states and world capitals, major bodies of water, and landmarks in major cities. You may also want to brush up on trivia about the presidents of the United States, recipients of major awards from the Oscars to the Nobel Prizes, things like that.”
