At the top of the Forgotten Gems list it says
Quote: This page lists those quizzes that have been online for many, many months but have been played very few times. These forgotten quizzes need to be played! So show them some love and help us get them ranked by playing them and then rating the quiz when you are done. As quizzes from this list are played by more players they will fall off this list and rejoin their pals.
I'm not 100% sure, but judging by the bold part I'd say that quizzes need to be rated 30 times before they disappear from the Forgotten Gems list. So for some quizzes that'll be after they've been played 30 times, others might need 60 plays before enough people have rated them.
