The finale is yours. Rank the three facts that surprised you most, ask the Restricted Section, an AI that is given only the checked facts from these stories, up to three questions, and read a short what-if scene, written as clearly marked fiction, about how a story like this might begin. Then keep a recap card with your quiz score, your vote on the hot take and your top three. The card is drawn on your device and saved as an image only if you choose; nothing you answer is stored once you close the tab. From the card you can go on to our article about the HBO series, play Continuity Check, where you spot the errors planted on a film set, or read about the symbol of the Deathly Hallows. If you spot a mistake in any of the thirty facts, the Contact page reaches the editors, and we will check it and correct it.
30 Harry Potter Facts Even Potterheads Don’t Know is a set of unofficial fan stories in seven short chapters, each on its own page. Tap the right side of the screen for the next slide and the left side to go back, hold to pause, and use the button at the end of a chapter for the next one. Three parts are written live by AI and labelled: a read of your answers, the Restricted Section and a what-if scene. The AI is told not to invent facts and can still make mistakes; if it is busy, a hand-written text appears instead and says so.
Every fact was checked on 14 October 2026 against pages we opened, all listed on the first page: Wikipedia’s articles on the books, the characters, the film locations and the HBO series, the official Harry Potter website’s feature on sentences that turned out to matter, and the Harry Potter Lexicon. The pictures are open-licence photos from Wikimedia Commons and our own drawings; no film stills or official art are used. Your answers stay in this browser tab and are cleared when you close it.
