The Extended Play version of the show uses the same questions. You'd think because of the amount of questions there are, that it would be rare to get the same thing twice, but there's several questions that I've seen twice, and I've only played like 5 games in total. It's possible that there's a few people that write/type all the correct answers down. You get like 5 seconds to answer after the question has been asked I think, plus an extra 2 or so before the answers even appear, so there's definitely enough time to Ctrl+F the question on a .txt file or something. So yeah, I wouldn't be surprised if you were right.

I think the Live version has a completely new set every time, but I might be wrong.

I wonder if the European version will be separate? If not, the questions will probably be biased in favor of Americans.
