Subcategories are small subdivisions of Sporcle quizzes. Subcategories range in size; larger subcategories include NBA and NFL; smaller ones include rugby and Bible.
What subcategories a quiz falls under is determined by the tags of the quizzes. It is important to note that not all quizzes have tags.
Curators manage each subcategory. On subcategory pages, the most recent curator's picks for each subcategory, along with the most recent editor's picks applying to quizzes with the subcategory's tag and published quizzes by the same rule.
