How do I create a quiz with wrong answers?

A wrong answer quiz is a special type of quiz on Sporcle where a quiz's bonus answers are actually marked as incorrect. To create bonus answers in quizzes put 'ee' in the last (extra) column. Move these answers to the last rows of the quiz. For wrong answers, you must check the appropriate box in the quiz creation center, and make sure all of your hints match just like a quiz with headings. We've also created a more detailed explanation over at the Sporcle Blog.
