Chapter 3 goes behind the books. In 1990 a train from Manchester to London was delayed by four hours, and Harry, Ron and Hermione came into J.K. Rowling’s head; with no pen to hand, she worked the characters out in her head until she got home. She gave Harry her own birthday, 31 July. Her publisher suggested using initials so that boys would not be put off by a woman’s name, and she chose K for her grandmother, Kathleen. Bloomsbury paid a £2,500 advance after the chief executive’s eight-year-old daughter called the book so much better than anything else, and the first print run of Philosopher’s Stone was just 500 hardbacks, 300 of which went to libraries; in 2021 one of them sold for as much as US$471,000. In the United States the book became Sorcerer’s Stone because the editor thought philosopher sounded too archaic, a change Rowling later said she regretted. The chapter ends with a hot take, whether the books are better than the films, and you see the best case for both sides before you vote.
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.
