50 free Sirius Black trivia questions with answers — literature quiz, new questions added Aug 2026.
Sirius Black is Harry Potter's godfather, the runaway heir of the House of Black, best man at James and Lily's wedding and the titular Prisoner of Azkaban. He is mentioned in the very first chapter of the series as the wizard who lent Hagrid a flying motorbike, spends twelve years wrongly imprisoned for Peter Pettigrew's crimes, becomes the first person to escape Azkaban under his own power, and dies at the Department of Mysteries at his cousin Bellatrix's hand. This quiz covers all of it: the constellation naming tradition, the Gryffindor sorting that broke with family habit, the Marauders and the Animagus dog called Padfoot, Uncle Alphard's inheritance, the fatal Secret-Keeper switch, Scabbers on the front of the Daily Prophet, Crookshanks and the Firebolt, the cave above Hogsmeade, Number 12 Grimmauld Place and Kreacher, the veil, the Resurrection Stone, and the family tree sold for £30,000 on Daniel Radcliffe's behalf. It also covers Gary Oldman, who took the part because he needed the money and did not know the character was going to die. Fifty questions, four options each, with a short explanation after every answer. Play on your phone or print it for a Harry Potter quiz night.
