I think I saw them in the brain teasers section. They were quizzes where there would be a jumbled up word and the questions would say to remove certain letters. By the last question, removing all the letters would form a phrase. What are these quizzes called?

That sounds like the Follow the Directions quizzes, found here:

You'll notice that we are not accepting new quizzes in that category at this time, but there are quite a few there for you to enjoy playing.
