I ran a Harry Potter round at a pub quiz in Leeds about three years ago, and the most confident team in the room — matching robes, the lot — scored four out of ten. Not because the questions were unfair. Because they'd watched the films twenty times and read the books twice, and they still couldn't tell you what O.W.L. stands for, which ghost haunts the Ravenclaw common room, or what Dumbledore's brother's name is. That's the thing about Harry Potter knowledge: it feels encyclopaedic until the moment someone asks you something specific, and then it evaporates faster than a Vanishing Spell.
What makes Harry Potter such brilliant quiz territory is exactly that gap between perceived expertise and actual recall. Almost everyone in a UK pub has read at least one book or seen at least one film. That means every table thinks they've got this round covered, and almost none of them do. The casual fans get tripped up by anything beyond the main plot. The hardcore fans get tripped up by the details the films quietly dropped. And the book purists — the ones who'll happily tell you the films got it wrong — sometimes can't remember which book introduced which character because they last read them as a twelve-year-old. It's a topic that generates genuine table debate, which is exactly what you want from a quiz round.
This post gives you fifty questions across five distinct rounds. We start with Hogwarts and its houses — architecture, history, the stuff the films glossed over. Round two covers spells and potions, where precision matters and spelling genuinely becomes relevant. Round three goes deep into characters and backstory, the kind of lore that lives in footnotes and appendices. Round four is dedicated to magical creatures, the most underrated area of Potter trivia. And round five is where things get spicy: books versus films, a round designed to reward people who've actually done both.
One practical note before you dive in: I'd strongly recommend splitting these rounds across two quiz nights rather than firing all fifty at a single session. Potter fans have stamina, but sustained difficulty without relief tips from challenging into demoralising pretty quickly. Alternatively, if you're running this as a standalone Potter special, intersperse a couple of picture rounds — cast photos, book cover art — to give people a breather. Also worth knowing: I've deliberately kept every question anchored to canonical text or confirmed film content. Nothing from Pottermore exclusives, nothing from the Fantastic Beasts films, nothing that requires you to follow J.K. Rowling on Twitter to have encountered it. Fair's fair.

Round 1: Hogwarts & Houses
This is the round that separates the people who watched the films from the people who actually paid attention. Hogwarts has a rich internal geography and history that the films only sketch, and a lot of these questions live in the gaps. Expect confident early answers followed by sudden, humbling silence around question six.
1. What is the full name of the moving staircase area at Hogwarts that connects the floors?
✓ The Grand Staircase
💡 Hogwarts has one hundred and forty-two staircases in total, according to the books — a detail the films couldn't fully show.
2. Which Hogwarts founder is associated with the element of water?
✓ Salazar Slytherin
💡 Each founder is linked to a classical element: Gryffindor to fire, Ravenclaw to air, Hufflepuff to earth, and Slytherin to water.
3. What O.W.L. grade is required to take a subject at N.E.W.T. level under standard Hogwarts entry requirements?
✓ 'Exceeds Expectations' or higher (E or O)
💡 O.W.L. stands for Ordinary Wizarding Level. The full grading system runs from O (Outstanding) down to T (Troll).
4. Which ghost is the official house ghost of Ravenclaw?
✓ The Grey Lady
💡 The Grey Lady is revealed in Deathly Hallows to be Helena Ravenclaw, the daughter of founder Rowena Ravenclaw.
5. In which year was Hogwarts School of Witchcraft and Wizardry founded, according to the books?
✓ Around 990 AD
💡 The exact founding year is never stated as a precise date in the books — 'around 990 AD' is the closest the text gets.
6. Name the caretaker of Hogwarts who served before Argus Filch.
✓ Apollyon Pringle
💡 Pringle is mentioned briefly by Molly Weasley, who recalls him caretaking during her own Hogwarts years in the 1960s.
7. What is the correct incantation to open the entrance to Dumbledore's office?
✓ It's a password, not an incantation — and the passwords are always names of sweets (e.g. Sherbet Lemon, Acid Pops)
💡 Dumbledore consistently uses confectionery as his office passwords throughout the series — a small, sweet character detail.
8. True or false: the Hufflepuff common room is located in the dungeons.
✓ False — it is near the kitchens, in the basement on the ground floor side of the castle
💡 Slytherin's common room is in the dungeons. Hufflepuff's is warm and earthy, accessed via a barely described tunnel near the kitchens.
9. Which professor taught History of Magic at Hogwarts throughout all seven books?
✓ Professor Cuthbert Binns
💡 Binns is unique among Hogwarts staff: he died at his desk and simply continued teaching the next day as a ghost.
10. What are the four subjects Harry Potter studies in his first year at Hogwarts? Name all four for full marks.
✓ Transfiguration, Charms, Potions, Defence Against the Dark Arts, History of Magic, Herbology, Astronomy, and Flying (accept any four of these eight)
💡 Flying is the only subject assessed in Year One that doesn't continue to N.E.W.T. level — it's essentially a single foundational term.
Round 2: Spells & Potions
Spells feel like an easy area until you realise most people only reliably know about eight of them. This round tests both recognition and precision — there are questions here where knowing the spell's name isn't enough and you'll need to know what it actually does, when it was first used, or who invented it. The potions questions are the sleeper difficulty in this round.
11. What does the spell 'Accio' do?
✓ It summons an object to the caster (a Summoning Charm)
💡 Accio is one of the oldest spells in the books — Harry uses it to summon his broomstick during the Triwizard Tournament's first task.
12. Which potion, described as gold and with swirling steam, gives the drinker the sensation of supreme confidence?
✓ Felix Felicis (Liquid Luck)
💡 Felix Felicis is extraordinarily difficult to brew — one mistake and the whole cauldron is ruined. It's banned in competitive situations.
13. What is the incantation for the spell that forces an opponent to drop whatever they're holding?
✓ Expelliarmus (the Disarming Charm)
💡 Expelliarmus becomes Harry's signature spell — Voldemort recognises it during the Battle of the Seven Potters, exposing Harry's identity.
14. Polyjuice Potion requires several ingredients — name two of them as listed in the books.
✓ Accept any two of: fluxweed, knotgrass, leeches, lacewing flies, boomslang skin, powdered Bicorn horn, and a piece of the person to be transformed into
💡 Hermione brews Polyjuice Potion in a second-floor girls' bathroom in Chamber of Secrets — it takes a full month to prepare.
15. What spell creates a magical map of an area and was used by the Order of the Phoenix to monitor Grimmauld Place?
✓ The Marauder's Map was not created by a spell — accept Homonculous Charm as the charm used in its creation
💡 The Homonculous Charm tracks every person within the mapped area and displays their name — an extraordinary piece of magic for its time.
16. Which spell did Severus Snape invent as a student, and what does it do?
✓ Sectumsempra — it slashes the target as if with an invisible sword, causing severe lacerations
💡 Snape invented Sectumsempra as a teenager and annotated it 'For Enemies' in his Half-Blood Prince textbook. Harry uses it on Draco.
17. What colour does a perfectly brewed Shrinking Solution turn?
✓ Bright acid green
💡 Neville Longbottom brews his Shrinking Solution incorrectly in Prisoner of Azkaban, turning it orange — which Snape uses to threaten his toad.
18. The incantation 'Morsmordre' produces which dark symbol in the sky?
✓ The Dark Mark (a skull with a serpent emerging from its mouth)
💡 The Dark Mark is conjured above wherever the Death Eaters have struck — it first appears in the books at the Quidditch World Cup.
19. Which potion, when drunk, causes the drinker to fall into a deep but temporary sleep resembling death?
✓ The Draught of Living Death
💡 The Draught of Living Death is the potion Snape challenges his first-year class to brew in their very first lesson in Philosopher's Stone.
20. What is the specific counter-curse for Sectumsempra, as performed by Snape in Half-Blood Prince?
✓ It is not given a named incantation in the text — Snape performs it non-verbally (accept: an unnamed healing spell performed by Snape)
💡 Rowling never gives the counter-curse a name in the books — only Snape knows it, as the inventor of the original spell.
Round 3: Characters & Backstory
This is the round where people's confidence tends to collapse around question four. Character backstory in Potter is genuinely dense — Rowling planted details across seven books that most readers absorbed passively at best. Questions about minor characters, family connections, and pre-Harry history are particularly lethal. I've included a couple of gentler ones near the top to give teams a running start before things get properly unpleasant.
21. What is the full name of Ron Weasley's rat, Scabbers?
✓ Peter Pettigrew (Scabbers is Peter Pettigrew in Animagus form)
💡 Scabbers had been in the Weasley family for twelve years before Prisoner of Azkaban — far longer than any normal rat's lifespan, a clue nobody noticed.
22. What is Dumbledore's full name?
✓ Albus Percival Wulfric Brian Dumbledore
💡 Rowling revealed the full name in an interview. 'Brian' is widely considered the funniest of the four middle names, and deliberately so.
23. What is the name of Dumbledore's brother, and what is his profession?
✓ Aberforth Dumbledore — he is the landlord of the Hog's Head Inn in Hogsmeade
💡 Aberforth was prosecuted for practicing inappropriate charms on goats — a gag Rowling plants early and never fully explains.
24. Which Death Eater was known as 'the Carrows' — and were they one person or two?
✓ Two people — Alecto Carrow and Amycus Carrow, a sister and brother
💡 The Carrows are installed at Hogwarts in Deathly Hallows. Alecto teaches Muggle Studies; Amycus teaches Defence Against the Dark Arts.
25. Before teaching at Hogwarts, what job did Remus Lupin hold, and why did he lose it?
✓ He had no mainstream job — he was unemployable due to his werewolf condition (accept: unemployed / lived in poverty due to lycanthropy)
💡 Lupin's poverty is emphasised by his patched robes and shabby appearance. Werewolf discrimination in wizarding society left him chronically unemployed.
26. What is the name of Voldemort's mother, and what was her family name before marriage?
✓ Merope Gaunt (née Gaunt, married name Riddle)
💡 Merope used a love potion on Tom Riddle Sr. When she stopped giving it, he left — abandoning her while she was pregnant with Voldemort.
27. Name the four Marauders, giving both their nicknames and their real names.
✓ Moony (Remus Lupin), Wormtail (Peter Pettigrew), Padfoot (Sirius Black), Prongs (James Potter)
💡 The nicknames reflect their Animagus or werewolf forms: Lupin is the only Marauder who couldn't choose his animal — it chose him.
28. What is Professor McGonagall's first name?
✓ Minerva
💡 Minerva is the Roman goddess of wisdom and strategic warfare — an apt name for a woman who coordinates Hogwarts' defence in Deathly Hallows.
29. Which character is described as the only known maker of the Philosopher's Stone, and what was his nationality?
✓ Nicolas Flamel — he was French
💡 Nicolas Flamel was a real historical figure, a 14th-century French scribe who became famous through legends about his alchemical work.
30. What position did Percy Weasley hold at the Ministry of Magic when he fell out with his family in Order of the Phoenix?
✓ Junior Assistant to the Minister for Magic (Cornelius Fudge)
💡 Percy's ambition blinds him to Fudge's failures for most of the series — he only reconciles with his family during the Battle of Hogwarts.
Round 4: Magical Creatures
Magical creatures are the most criminally underused category in Harry Potter quizzes, which is a shame because Rowling put an enormous amount of thought into the bestiary. This round goes beyond dragons and hippogriffs — there are creatures here that appear only once in the books, creatures defined by rules the films quietly dropped, and at least one question where knowing the creature's diet turns out to matter. Consider yourself warned.
31. What is a Bowtruckle, and what does it primarily eat?
✓ A Bowtruckle is a small, insect-like tree guardian; it eats woodlice and fairy eggs
💡 Bowtruckles only inhabit wand-quality trees and will scratch eyes if threatened — Newt Scamander keeps one named Pickett in Fantastic Beasts.
32. A Basilisk can kill with its gaze — but what does it do to a person who sees its eyes indirectly, such as through a reflection?
✓ It Petrifies them rather than killing them
💡 This rule saves multiple Hogwarts students in Chamber of Secrets — Hermione deduced the Basilisk's nature from this indirect-reflection clue.
33. What Ministry of Magic classification is assigned to a dragon?
✓ XXXXX — the highest danger rating (known as 'Known Wizard Killer / Impossible to Train or Domesticate')
💡 The Ministry's classification system runs from X (boring) to XXXXX (extremely dangerous). Dragons are one of only a handful of XXXXX creatures.
34. What is the name of the creature that feeds on human happiness, reproduces by forcing its victim to relive their worst memories, and can only be repelled by a Patronus?
✓ A Dementor
💡 Rowling has said Dementors are based on her own experience of depression — the feeling of happiness being completely drained away.
35. Which magical creature is described as having the body of a horse and the wings and head of an eagle, and what is the correct greeting ritual when approaching one?
✓ A Hippogriff — you must make eye contact, bow, and wait for it to bow back before approaching
💡 Buckbeak the Hippogriff is sentenced to death after attacking Draco — but Draco deliberately skipped the bowing ritual to provoke him.
36. What is a Thestral, and what is the condition for being able to see one?
✓ A Thestral is a winged, skeletal black horse; you can only see them if you have witnessed death and fully processed the experience
💡 Harry can see Thestrals from Order of the Phoenix onward — he witnessed his parents' deaths as a baby but was too young to process them.
37. Name the three Unforgivable Curses.
✓ The Killing Curse (Avada Kedavra), the Cruciatus Curse (Crucio), and the Imperius Curse (Imperio)
💡 All three are made legal by Voldemort's regime during Deathly Hallows — Death Eater teachers at Hogwarts practise the Cruciatus on students.
38. What does a Niffler primarily seek out, and what magical property makes it useful to treasure hunters?
✓ Nifflers are attracted to shiny objects; their pouch-like stomach can hold far more than its external size suggests
💡 Nifflers appear in Goblet of Fire when Hagrid uses them in a Care of Magical Creatures lesson — long before Fantastic Beasts popularised them.
39. A Phoenix, such as Dumbledore's Fawkes, has two specific magical abilities beyond flight — name both.
✓ Their tears have healing properties, and they can carry extremely heavy loads (their feathers also make powerful wand cores — accept either additional point)
💡 Fawkes saves Harry's life in Chamber of Secrets using both abilities simultaneously: carrying him out while his tears cure the Basilisk venom.
40. What is the name of the giant spider colony that lives in the Forbidden Forest, and who is their leader during Harry's years at Hogwarts?
✓ The Acromantulas — the colony is led by Aragog
💡 Hagrid raised Aragog from an egg and hid him in a cupboard at Hogwarts — the incident that got him expelled in his third year.
Round 5: Books vs Films
This is the round that causes the most arguments, which is precisely why I included it. The Potter film adaptations made dozens of deliberate changes — some smart, some baffling — and this round specifically rewards people who've engaged with both versions rather than just one. A few of these questions will feel obvious to book readers and invisible to film-only fans, and that tension is the entire point.
41. In the books, Harry's eyes are repeatedly described as a specific colour — a trait inherited from his mother. What colour, and did the film casting match it?
✓ Green in the books — Daniel Radcliffe's eyes are blue, and the films did not use coloured contact lenses (he was allergic to them)
💡 Rowling repeatedly emphasises Harry's green eyes as key to the plot — several characters comment on his resemblance to Lily. The films quietly dropped this.
42. Which major character death occurs in the book version of Goblet of Fire but is handled significantly differently in terms of the aftermath scene in the film?
✓ Cedric Diggory's death — in the book, the crowd rushes in chaotically; in the film, it is a quieter, more controlled scene with Amos Diggory's grief foregrounded
💡 Robert Pattinson played Cedric Diggory — his first major film role — before being cast as Edward Cullen in Twilight four years later.
43. The Burrow is attacked and partially burned in which film — an event that does not occur in the corresponding book?
✓ Harry Potter and the Half-Blood Prince (2009)
💡 Director David Yates added the Burrow attack to give the film an early action sequence. Many book readers found it an unnecessary invention.
44. In the books, who delivers the line "Harry, did you put your name in the Goblet of Fire?" — and how does the books' version of this scene differ from the film's famously intense version?
✓ Dumbledore asks it in both — but in the book he asks 'calmly'; in the film, Michael Gambon's Dumbledore grabs Harry aggressively, causing long-running fan complaints
💡 The stage direction 'asked calmly' in Goblet of Fire became one of the most quoted book-to-film discrepancies in Potter fan discussion history.
45. Which Hogwarts professor appears in the books from Chamber of Secrets onward but is entirely absent from the film version of that story?
✓ Professor Sprout has a reduced role, but the most notable omission is Peeves the Poltergeist — though he is not a professor (accept: Peeves, cut entirely from all films)
💡 Rik Mayall filmed scenes as Peeves for the first film but was cut in editing. Those scenes have never been officially released.
46. In the book version of Prisoner of Azkaban, how does Harry discover the truth about Sirius Black's innocence? Which character explains the full story first?
✓ Remus Lupin explains the full story in the Shrieking Shack — the film handles this the same way
💡 Alfonso Cuarón directed Prisoner of Azkaban — widely considered the best film in the series by critics, though fans often prefer Philosopher's Stone for nostalgia.
47. The film version of Order of the Phoenix cuts a subplot involving which Weasley sibling that features prominently in the book?
✓ Percy Weasley — his estrangement from the family and his role at the Ministry is almost entirely cut from the film
💡 Percy's subplot across books five through seven is a slow-burn redemption arc. Cutting it from the films made his return in Deathly Hallows feel abrupt.
48. In the books, how does Voldemort die at the end of Deathly Hallows — and how does the film depict this differently?
✓ In the book, Voldemort dies in front of the whole school and simply falls dead like an ordinary man; in the film, he disintegrates into ash and blows away dramatically
💡 Rowling has said she deliberately made Voldemort's book death mundane — to emphasise his humanity and mortality rather than his supernatural status.
49. Which scene involving Dumbledore's Army in Order of the Phoenix appears in the book but was cut from the film, involving a specific piece of magic used to prevent betrayal?
✓ Hermione jinxes the D.A. sign-up parchment so that anyone who betrays the group gets the word 'SNEAK' written across their face in boils — used on Marietta Edgecombe
💡 In the film, Cho Chang is blamed for the betrayal directly. In the book, it's her friend Marietta — a distinction that significantly changes how Cho is portrayed.
50. True or false: in the book version of Philosopher's Stone, Hermione uses the spell 'Alohomora' to open the door into the forbidden third-floor corridor. In the film, this scene plays out identically.
✓ True — both the book and film use Alohomora in this scene; it is one of the earliest spells shown in either version
💡 Alohomora derives from the Mandé language of West Africa — 'aloho' means 'friendly to thieves'. Rowling sourced many spell names from real linguistic roots.
What strikes me every time I put together a Potter quiz is how much the series rewards the kind of reader who treats fiction like a document rather than an experience. The clues are all there — the too-old rat, the too-calm Dumbledore, the eyes that should be green. Rowling hid things in plain sight across seven books and trusted readers to either catch them or feel the satisfaction of a pay-off they didn't see coming. That's actually extraordinary craft for what is nominally a children's series, and it's why Potter quiz questions can be genuinely layered in a way that, say, a Roald Dahl round often can't quite match. I find the books vs films category the most revealing of the five rounds here, because what people notice and retain says something about how they read — whether they're tracking plot or texture.
