This is the deepest Harry Potter quiz on the site: 140 free questions with answers spanning all seven books, the eight films and the story of how the series was published. It opens with warm-ups on houses, wands, Quidditch and the Marauder's Map, then works book by book through the plots, from Firenze's warning in the Forbidden Forest to Molly Weasley's duel with Bellatrix and the names in the epilogue, and finishes with genuinely hard Harry Potter book trivia: print runs, rejected titles, translations and the editor who bought the manuscript. Book readers will find questions the films skipped; film fans will find plenty they recognise. It works as a solo test or as several rounds for a Potter-themed quiz night. Every answer has been checked against a reference source and each question shows its citation.
