Famous and Classic Riddles
PLAY
Some riddles have survived for thousands of years. This collection gathers the most famous riddles in history with answers, and an origin note on the oldest ones, starting with the riddle of the Sphinx that Oedipus solved. You'll also find classic riddles from the Bible, Norse myth, Victorian puzzle books, and the schoolyard.
Old famous riddles stack contradictions, the hard run turns to letters and scenes
Contradiction does more work on this page than any other trick. The Sphinx opens with legs counted across one lifetime, then the mountain has deep roots and no growth, the echo speaks with no mouth, and the towel gets wetter the better it dries you. When a line insists on two things that cannot both be true, stop hunting for a creature and ask which object makes both halves true.
The hard run that fills cards 51 to 72 asks for something else. Nearly half of it hands you the letters themselves: one number loses a letter and comes out even, another keeps its whole sound after four of its five letters go. Most of the rest sets a scene, like the man who stops at the seventh floor unless it rains. Four cards do neither, from a mined core in a wooden case to the elbow your right hand can never reach.
An origin note is context on most cards, not a solving step: the headless maidens in white hoods and the thief who ate a scholar's words give up everything in the wording. A few really do need the source: Samson's eater and strong stays shut until you hear about the lion. Several of the oldest cards, the thirty white horses among them, also turn up in the riddle game Bilbo trades with Gollum on the Hobbit riddles page. For the same puzzles sorted by the assumption they hide, try the logic riddles.
- Riddle 2: most people say The sun and the moon. Sun and moon are the pair everyone reaches for, and neither one produces the other. In turn is the phrase that removes them, since it asks each sister to end at the exact moment the other begins.
- Riddle 10: most people say A piano. Keys with no locks fit an upright piano, so it is a fair first answer. Space but no room is what removes it, because a piano has no space bar and nothing on it is labelled enter.
- Riddle 39: most people say Five legs. Adding one is a reflex, and the question never says the tail turned into a leg. Calling it a leg leaves the animal exactly as it was, so the count under the dog does not move.
- Riddle 65: most people say Four people. Two plus two is four only when each role sits on a different person. Nothing in the wording keeps them apart, so the man in the middle answers to two titles and three rods bring home three fish.
When two clues contradict each other, hunt for the single object that makes both true instead of the creature the words suggest.
-
1. What walks on four legs in the morning, two legs at noon, and three legs in the evening? Easy
Need a hint?
Morning, noon, and evening stand for the stages of a whole life.
Show answer
A human. We crawl as babies, walk upright as adults, and use a cane in old age. This is the riddle of the Sphinx, which Oedipus solved in Greek myth.
The three times of day are not hours at all: they mark one whole lifetime, so the leg count tracks a crawling baby, an upright adult, and an elder leaning on a stick.
-
2. There are two sisters: one gives birth to the other and she, in turn, gives birth to the first. Who are the two sisters? Medium
Most people first say: The sun and the moon
Need a hint?
They take turns, forever, and neither can exist without the other.
Show answer
Day and night. This is the second, lesser-known riddle of the Sphinx from Greek tradition.
Gives birth reads as family, and here it means coming after. Each state ends by starting the other, so the two sisters are the halves of a single turning day.
-
3. Out of the eater came something to eat, and out of the strong came something sweet. What is it? Hard
Need a hint?
Samson had recently killed a lion, and bees had moved in.
Show answer
Honey from a lion's carcass. This is Samson's riddle from the Book of Judges, one of the oldest riddles ever written down.
Bees nested in a slain lion, so the strong eater yielded sweet honey inside.
-
4. As I was going to St. Ives, I met a man with seven wives. Each wife had seven sacks, each sack had seven cats, each cat had seven kits. Kits, cats, sacks, and wives, how many were going to St. Ives? Medium
Most people first say: Two thousand eight hundred
Need a hint?
You met them. Which direction were they walking?
Show answer
Just one: you. Everyone else was coming FROM St. Ives. This English rhyme dates back to at least 1730.
Met is the hinge: the whole procession was walking away from town, so all those sevens sit there to start you multiplying instead of counting travelers.
-
5. Thirty white horses on a red hill. First they champ, then they stamp, then they stand still. What are they? Easy
Most people first say: Chess pieces
Need a hint?
The red hill is inside your head.
Show answer
Teeth. A traditional English folk riddle, later made famous by a certain riddle game in a dark cave.
The horses are a picture, not animals: thirty small pale things standing in rows above a red slope, champing and then still, put you inside a mouth.
-
6. My roots run deep where nobody goes. I stand taller than any tree, yet I have never grown an inch. What am I? Medium
Need a hint?
My roots reach deep into the earth, but I am not alive.
Show answer
A mountain. Riddles in this shape go back to old Anglo-Saxon and Norse tradition.
Roots and height sound like a plant, and the flat claim that it never gained an inch cancels that. What stands rooted and tall without ever growing is landscape, not life.
-
7. I speak without a mouth and hear without ears. I have no body, but I come alive with wind. What am I? Easy
Most people first say: A ghost
Need a hint?
Shout across a canyon and I answer you.
Show answer
An echo. One of the most repeated classic riddles in the world.
Speaking and hearing suggest a creature, yet nothing here owns a body. A sound bounced back off rock does all of it, which is why moving air carries the answer.
-
8. In Greek myth, what happened to the Sphinx after Oedipus answered her riddle correctly? Medium
Show answer
She destroyed herself
In most tellings the Sphinx threw herself from her rock and died. Thebes was freed, and Oedipus was made king soon after.
-
9. A thief crept through a monastery library and ate a scholar's finest words, yet swallowed no wisdom at all. Monks wrote about me a thousand years ago. What is the thief? Medium
Most people first say: A hungry mouse
Need a hint?
It chews through pages but never learns a thing.
Show answer
A bookworm. This retells Riddle 47 from the Exeter Book, a manuscript of Old English riddles copied down around the year 975.
Eating words sounds like taking in knowledge, and the line about gaining no wisdom denies exactly that. What is left is the literal reading: something chewing paper on a shelf.
-
10. What has keys but can't open locks, space but no room, and you can enter but can't go inside? Easy
Most people first say: A piano
Need a hint?
You are probably close to one right now.
Show answer
A keyboard. A modern classic built on the much older piano riddle.
Three computer words get read as house words first: keys that unlock, a space you stand in, a door you walk through. Treat all three as labelled buttons instead.
-
11. I am a little box with no hinges, no lock, and no lid, yet golden treasure hides inside me. What am I? Easy
Most people first say: A treasure chest
Need a hint?
The treasure is the yolk.
Show answer
An egg. An old folk riddle form found in collections long before it turned up in fantasy novels.
Box, hinges, and lid send you hunting for something built by hands. No maker leaves a container without a seam, so the gold sits inside a shell you break instead.
-
12. What is greater than God, more evil than the devil, the poor have it, the rich need it, and if you eat it you'll die? Medium
Most people first say: Death itself
Need a hint?
The answer is hiding in plain sight in the question.
Show answer
Nothing. Nothing is greater than God, nothing is more evil than the devil, and if you eat nothing you die. A famous trick riddle passed around for generations.
Searching for an object is the mistake here. Allow an empty answer instead and each impossible comparison turns true at once, including the deadly one about eating.
-
13. I live but never breathe. I am cold as the grave. I drink all day yet am never thirsty, and I wear shining mail that makes no sound. What am I? Medium
Most people first say: A suit of armor
Show answer
A fish
Never breathes and cold as the grave read as dead, yet this thing drinks all day. Gills, cold blood, and overlapping scales that shine like armor belong to a water creature.
-
14. What can run but never walks, has a mouth but never talks, has a head but never weeps, has a bed but never sleeps? Easy
Need a hint?
It starts in the mountains and ends at the sea.
Show answer
A river. One of the most anthologized riddles in English.
Mouth, head, and bed are body and bedroom words in plain speech, and each is also a map word for water: the place it empties, its source, and the channel it lies in.
-
15. The riddle of the Sphinx appears in the ancient Greek play 'Oedipus Rex' word for word. Medium
Show answer
False.
False. Sophocles never states the riddle in the play. The audience already knew it, so the text only refers to it. The full wording comes from other ancient sources.
-
16. I devour everything: birds and beasts, trees and flowers. I wear down iron, crumble castles, and turn mountains into sand. Even kings cannot escape me. What am I? Medium
Most people first say: A dragon
Need a hint?
I defeat mountains and kings alike, but very slowly.
Show answer
Time. The 'time devours all' riddle is an ancient form, made newly famous by literature's most dangerous riddle game.
Each clue is chosen to rule out a physical eater. Teeth could manage flowers, but nothing with a body wears iron thin or beats a king, which leaves a force that works by lasting.
-
17. I am always hungry and must always be fed. The finger I touch will soon turn red. What am I? Easy
Most people first say: A hungry baby
Need a hint?
Feed me wood and I grow. Feed me water and I die.
Show answer
Fire. A classic riddle found in collections across many languages.
Hunger belongs to animals, and that is the misdirection. Read feeding as adding fuel and the red finger as a burn, then the eater with no stomach shows up.
-
18. What English word is always spelled incorrectly? Medium
Most people first say: The word wrong
Need a hint?
Read the question again, very literally.
Show answer
The word 'incorrectly.' A famous schoolyard trick question.
Spelled incorrectly gets read as spelled wrongly, though it can also name the letters themselves. Once the phrase describes its own spelling, the question answers itself.
-
19. The famous 'Einstein riddle' asks who owns a certain pet, given clues about five houses. Which pet is it? Medium
Show answer
The fish
The classic zebra-puzzle variant credited to Einstein asks who keeps the fish. There is no proof Einstein wrote it, which is part of its legend.
-
20. A man looks at a portrait and says: 'Brothers and sisters I have none, but that man's father is my father's son.' Who is in the portrait? Hard
Most people first say: His brother
Need a hint?
Replace 'my father's son' with the person it must be.
Show answer
His son. 'My father's son' is the speaker himself, so the portrait shows the speaker's son. A famous logic riddle from Victorian puzzle books.
No siblings is the load-bearing line. With no brother in the family, my father's son has to be the speaker himself, and that man's father places the picture one generation below.
-
21. What comes once in a minute, twice in a moment, but never in a thousand years? Medium
Need a hint?
Stop thinking about time. Look at the words.
Show answer
The letter M. A print classic since the 1800s.
Ignore time and count letters: M appears once in minute, twice in moment, never in years.
-
22. I saw maidens marching over the sea. Each wore a white hood, yet not one of them had a head. Who were they? Medium
Most people first say: Ships under sail
Need a hint?
Watch the water near the shore on a windy day.
Show answer
Waves, wearing hoods of white foam. This comes from the Old Norse saga of King Heidrek, where Odin in disguise plays a riddle contest with a king.
Maidens with no heads are the signal to un-person the picture: rows of something moving toward shore, each capped in white, marching the way water does in a wind.
-
23. Riddle contests appear in Norse mythology, including one where Odin competes in disguise. Medium
Show answer
True.
True. In the Vafthrudnismal, Odin has a life-or-death wisdom contest with the giant Vafthrudnir, and he wins with an unanswerable question.
-
24. Four hang, four sprang, two point the way, two ward off dogs, one dangles after, always rather dirty. What is it? Hard
Most people first say: A horse
Need a hint?
Picture a farm animal, piece by piece.
Show answer
A cow. Four teats hang, four legs spring, two horns point, two hind legs kick at dogs, and the tail dangles. A riddle in the old Norse style.
Tally the parts before you name the creature. Four things that hang plus four that spring means legs and udder together, and the dog-warding pair are back hooves on a barnyard milker.
-
25. I spend my whole life drying others, and the better I do my job, the wetter I become. What am I? Easy
Most people first say: A sponge
Need a hint?
You grab me the moment you step out of the bath.
Show answer
A towel. This small paradox has been a favorite of printed riddle books since the 1800s.
Better at drying should mean drier, and that expectation is what flips. The water has to go somewhere, so success and soaking are one event for cloth in a bathroom.
-
26. The oldest known riddles were written on clay tablets. Which civilization left them to us? Medium
Show answer
Sumer in Mesopotamia
Sumerian school tablets from around 4,000 years ago carry the earliest riddles we can still read today.
-
27. I have cities, but no houses. I have mountains, but no trees. I have water, but no fish. What am I? Easy
Most people first say: A globe
Need a hint?
You can fold me up and put me in a glovebox.
Show answer
A map. A modern classic repeated in nearly every riddle book of the last century.
Each pair sets a place against what should be inside it, so no real location survives the list. What is left is a flat printed copy of places, small enough to fold.
-
28. What is so fragile that saying its name breaks it? Easy
Most people first say: A soap bubble
Need a hint?
You can keep it or break it, but never touch it.
Show answer
Silence. One of the most shared riddles on the internet, with roots in much older word riddles.
Speaking its name aloud makes noise, and any sound instantly ends the silence.
-
29. An eye in a blue face saw an eye in a green face. 'That eye is like to this eye,' said the first, 'but in low place, not in high place.' What is it? Hard
Most people first say: The moon on a pond
Need a hint?
One face is the sky, the other a summer lawn.
Show answer
The sun shining on daisies
Faces here are backgrounds: blue means sky, green means grass. Once an eye reads as a round bright thing set in a field of color, a high one looks down at a low one.
-
30. 🦁 + 🐝 Medium
Most people first say: The Lion King
Need a hint?
Think of the oldest riddle in this collection.
Show answer
Honey from the lion (lion + bee): a nod to Samson's famous riddle.
Emoji pairs usually blend into one word, and this pair refuses. Instead the two animals quote the Samson story from earlier on the page, where a swarm settled in a dead beast.
-
31. In 'Harry Potter and the Goblet of Fire,' a sphinx blocks the maze with a riddle. Its answer is a creature Ron would hate. Which one? Medium
Show answer
A spider
The sphinx's riddle builds the word 'spider' piece by piece. Harry solves it and keeps his wand ready, just in case.
-
32. The phrase 'riddle of the Sphinx' refers to a puzzle from ancient Egypt. Easy
Show answer
False.
False. The famous riddle belongs to the Greek Sphinx of Thebes. The Egyptian sphinx statues, like the one at Giza, ask no riddles at all.
-
33. 'Why is a raven like a writing desk?' is a famously unanswered riddle. Who asks it? Medium
Show answer
The Mad Hatter
The Mad Hatter asks it in 'Alice in Wonderland' and admits he has no answer. Lewis Carroll invented one later: 'Because it can produce a few notes.'
-
34. A wondrous creature comes sailing, deadly and beautiful, carrying cold water in its belly. The more of its sisters it gathers, the more ships it can drown. What is it? Medium
Most people first say: A pirate ship
Show answer
An iceberg. This reworks a riddle about ice from the Exeter Book, the same Old English manuscript as the bookworm riddle.
Creature, belly, and sisters dress a floating block of ice as a living thing. Undress it: something that drifts without sailing and grows deadlier as more of them gather.
-
35. In a famous opera, a princess demands to know: what is born anew every night and dies every dawn, rising in the heart of every person? What answer saves the prince? Medium
Most people first say: A dream
Show answer
Hope. It is the first of Princess Turandot's three riddles in Puccini's opera 'Turandot.'
The clue points at a feeling rather than an object: something reborn nightly, gone by dawn, alive in every chest. Puccini's princess asks this one first, and the prince must name it before he faces her other two.
-
36. Little Nancy Etticoat, in a white petticoat and a red nose, stands and stands, and the longer she stands the shorter she grows. What is she? Easy
Most people first say: A little girl
Show answer
A candle. A traditional nursery riddle printed in old Mother Goose collections.
Nancy is a costume for an object: a white body with a red top that loses height while standing still. Nothing alive shrinks by standing, which rules out girls in petticoats.
-
37. Old Mother Twitchett has but one eye and a long tail she can let fly, and every time she passes through a gap she leaves a little of her tail behind. What is she? Medium
Show answer
A needle and thread. A classic riddle from old Mother Goose rhymes.
One eye and a long tail sound like an animal until the loss matters. No creature sheds part of its tail at every gap, but a sewing tool leaves a stitch behind on each pass.
-
38. I am born in winter and die in summer, and I grow toward the ground with my roots pointing up. What am I? Medium
Show answer
An icicle. A traditional folk riddle found in many old rhyme collections.
A plant grows up from its roots, and this thing does the reverse: it builds downward from a roof, arriving in cold and vanishing in heat, which makes it water caught mid-drip.
-
39. How many legs does a dog have if you call its tail a leg? Easy
Most people first say: Five legs
Show answer
Four. Calling a tail a leg does not make it one. This point is famously attributed to Abraham Lincoln.
Renaming a tail does not change reality, so the dog still has four legs.
-
40. A rooster sits at the very peak of a slanted barn roof and lays an egg. Which side of the roof does the egg roll down? Easy
Most people first say: The steeper side
Show answer
Neither side. Roosters do not lay eggs. A favorite schoolyard trick question.
Roosters cannot lay eggs, so the premise fails and no egg rolls anywhere.
-
41. A suitor must choose among three chests of gold, silver, and lead to win a bride. The lead one warns, 'Who chooses me must give and risk all he has.' Which chest holds her portrait? Medium
Most people first say: The gold chest
Show answer
The lead casket. In Shakespeare's 'The Merchant of Venice,' the humble lead chest holds the winning prize.
In Shakespeare's play the humble lead casket, not the showy metals, holds the portrait.
-
42. The more of them you take, the more you leave behind you. What are they? Easy
Show answer
Footsteps. A classic riddle repeated in countless puzzle books.
Take reads as removing something, and here it means taking a stride. Each one you spend puts another mark on the path behind you, so taking and leaving rise together.
-
43. Whoever makes it has no use for it. Whoever buys it does not keep it. Whoever needs it never knows. What is it? Medium
Most people first say: A gravestone
Show answer
A coffin. A grim old riddle passed around for generations.
Three people handle it and none of them uses it: the maker, the buyer, and the one it is meant for. That last clue works only if the person cannot know, which lands you in a cemetery.
-
44. What can travel all the way around the world while staying stuck in one corner? Easy
Show answer
A postage stamp. A classic printed riddle from the age of letters.
Travel and stuck cannot both be true of one thing unless the traveler is a passenger. Something glued to the corner of an envelope rides along without moving itself.
-
45. It only ever goes up and never comes back down, no matter what anyone does. What is it? Easy
Most people first say: A balloon
Show answer
Your age. A well-worn riddle from countless puzzle books.
Going up sounds like motion, so people hunt for something physical. Nothing in the wording promises an object, and a count that climbs on each birthday never moves at all.
-
46. I hold thirteen hearts, yet I have no other organ anywhere in my body. What am I? Medium
Show answer
A deck of cards, counting the thirteen cards of the hearts suit.
Hearts is read as the organ and used as a suit name. Thirteen of them with no other organ in the body means paper, not flesh, and thirteen is exactly what one suit holds.
-
47. You can catch me quite easily, but no matter how hard you try, you can never throw me. What am I? Easy
Show answer
A cold. A classic bit of riddle wordplay.
Catch and throw feel like a matched pair, yet just one of them works with an illness. English lets you catch a bug and offers no way at all to throw one back.
-
48. What kind of room has no doors, no windows, and no walls to speak of? Easy
Show answer
A mushroom. A famous joke riddle beloved by children.
Nothing here is a real room, so stop furnishing it and listen instead. The name of a fungus ends in those same four letters, and the joke lives in that sound alone.
-
49. When is a door not a door? Easy
Most people first say: When it is open
Show answer
When it is ajar. This pun on 'a jar' is one of the oldest joke riddles in English, in print since the 1700s.
Ajar means slightly open, and said aloud it splits into two words for a glass container. The question works only when you hear the break between article and noun.
-
50. What can fill an entire room yet take up no space at all? Easy
Most people first say: The air
Show answer
Light. A classic riddle found in puzzle books everywhere.
Fill and take up space sound like the same idea, and separating them is the whole move. Something can reach every corner without weighing anything or pushing furniture aside.
-
51. There is one English word in which the first two letters make a male, the first three a female, the first four a great man, and the whole word a great woman. What is the word? Hard
Most people first say: The word hero
Need a hint?
Peel the word two letters at a time from the left.
Show answer
Heroine
Read the word from the left, two letters at a time, then three, then four. Each stage is a real word about a person, and the last one has to name a woman of standing.
-
52. I am an odd number, but take away a single letter and I suddenly become even. What number am I? Hard
Most people first say: The number nine
Need a hint?
Spell the number out, then take away its first letter.
Show answer
Seven
Odd and even sound like arithmetic, and the puzzle is about letters. Strike the first letter off the spelled-out number and the four that remain spell the opposite kind.
-
53. Which everyday English word contains three sets of double letters, one right after another? Hard
Most people first say: The word committee
Need a hint?
Think of a job title made from two words joined together.
Show answer
Bookkeeper
Double letters have to sit side by side with nothing between them, which throws out most long words. What survives is a job title built from two nouns stuck together.
-
54. A certain word has six letters, but remove just one letter and twelve of something remain. What is the word? Hard
Need a hint?
Six letters, and one of them is doing plural work.
Show answer
Dozens
Drop the final s from dozens and you are left with a dozen, which is twelve.
-
55. What five-letter English word keeps the exact same sound even after you remove four of its five letters? Hard
Need a hint?
Say it out loud, then name a single letter.
Show answer
Queue
Say the word out loud before you count anything. It comes out as a single letter name, so the other four are along for the ride and losing them changes nothing you hear.
-
56. Stand me on my side and I am everything there is, but cut me in half and I am nothing at all. What am I? Hard
Most people first say: The infinity sign
Need a hint?
Think about the printed shape, not the value.
Show answer
The number 8
Everything and nothing are shapes here, not amounts. Turn the printed figure ninety degrees and it becomes the sideways loop for endlessness; slice it across the waist and each half is a ring worth zero.
-
57. I am dug from a mine and shut inside a wooden case I will never leave, yet nearly everyone puts me to work. What am I? Hard
Most people first say: A lump of coal
Need a hint?
The wooden case is a handle you hold every day.
Show answer
Graphite, the lead in a pencil
Dug from a mine says mineral, and the wooden case is the strange part, since no precious rock gets sealed in timber on purpose. The wood makes sense as a handle for a grey writing core.
-
58. A man rides the elevator down from the tenth floor every morning, but coming home he rides only to the seventh floor and walks the rest, unless it is raining, when he rides all the way up. Why? Hard
Most people first say: He needs the exercise
Need a hint?
What does he carry only when it rains?
Show answer
He is too short to reach the top button, but an umbrella lets him press it on rainy days
Nothing in the story says the man can reach every button. The umbrella explains it: on wet days he carries something long, and rain has no other reason to change which floor he stops at.
-
59. A man pushes his car up to a hotel, hands over some money, and declares himself bankrupt, yet he is not upset at all. Why not? Hard
Most people first say: His car broke down
Need a hint?
Look at the board, not the road.
Show answer
He is playing Monopoly
His car token landed on a hotel property, forcing a payment that bankrupts him in the board game.
-
60. Police raid a house to arrest a killer named John and find a plumber, a lawyer, a mechanic, and a firefighter playing cards, then arrest the firefighter at once. How did they know? Hard
Need a hint?
Nothing here says all four players are men.
Show answer
The firefighter was the only man, since the other three were women
The list of jobs invites you to picture four men, and the name John does the rest. Read the professions without assuming gender and just one person at that table can carry the name.
-
61. A traveler rides into a town on Friday, stays for three nights, and rides back out on Friday. How is that possible? Hard
Most people first say: He crossed the date line
Need a hint?
Not every Friday is a day of the week.
Show answer
His horse is named Friday
Friday is read as a date, and the sentence never says it is one. Treat the word as a name for something he rides and the three nights stop being a problem.
-
62. Before Mount Everest was ever discovered by climbers, which mountain was the tallest on Earth? Hard
Most people first say: The mountain K2
Need a hint?
Being found and being tall are different things.
Show answer
Mount Everest
Discovered is doing the misleading work here. Height does not wait for a survey team, so the tallest peak before anyone mapped it is the same one that holds the record now.
-
63. There is a common word that changes how it is pronounced the moment you give its first letter a capital. What word is it? Hard
Need a hint?
Try it with a capital letter and say it aloud.
Show answer
Polish
Lowercase polish means to shine, while capital Polish refers to Poland, and the two sound different.
-
64. What can you drop into a full bucket of water to make the bucket lighter rather than heavier? Hard
Most people first say: An ice cube
Need a hint?
You can add an absence to something.
Show answer
A hole
Drop in reads as adding an object, and an absence can be added too. Once you allow that, water leaves through the gap and the pail gets lighter by losing rather than gaining.
-
65. Two fathers and two sons go fishing, each one catches a fish, yet only three fish are caught in all. How does that add up? Hard
Most people first say: Four people
Need a hint?
One person can hold two roles at once.
Show answer
There were only three people, a grandfather, his son, and his grandson
Adding two and two is the reflex, and the wording never says the roles belong to different men. The man in the middle answers to both titles at once, so three anglers cover four labels.
-
66. What five-letter word actually becomes shorter when you add two more letters to it? Hard
Need a hint?
Count the letters, not the thing described.
Show answer
Short
Length of the word is what changes, not the length of anything it describes. Two letters tacked on the end turn a five-letter word into its own comparative form.
-
67. A woman points something at her husband and presses a button, then holds him underwater for half a minute, and later they sit down to dinner together, perfectly happy. How? Hard
Most people first say: She attacked him
Need a hint?
The button she presses makes a click, not a bang.
Show answer
She is a photographer developing his photo
She snaps his picture with a camera and rinses the print in a chemical bath, harming no one.
-
68. Read one way I am a heavy weight, but spell me backward and I mean the opposite of yes. What word am I? Hard
Need a hint?
Read the three letters from right to left.
Show answer
Ton
Reading a word backward is a legal move here, and the reversal turns a unit of weight into a flat refusal. Two spellings, three letters, opposite jobs in a sentence.
-
69. There is a word from which you can remove one letter at a time, again and again, and still have a real word at every step, all the way down to a single letter. What is it? Hard
Need a hint?
The middle letters are the ones you can spare.
Show answer
Startling
Nine letters have to survive eight deletions, so hunt for a word whose middle is all optional. Peel one at a time and every stage stays in the dictionary, down to a single vowel.
-
70. In a famous ancient paradox, a swift hero can never overtake a slow tortoise that started ahead of him, because every time he reaches where it was, it has crept a little farther. What is this puzzle called? Hard
Most people first say: The tortoise and the hare
Need a hint?
Name the Greek philosopher who denied motion.
Show answer
Zeno's paradox of Achilles and the tortoise
The description is accurate, so the only missing piece is a label from the history of philosophy. A Greek thinker built this chase to argue that motion cannot be what it looks like.

71. You face two doors and two guards, one who always lies and one who always tells the truth, but you do not know which is which. With a single question to one guard, how do you find the safe door? Hard
Need a hint?
Find a question both of them must answer the same way.
Show answer
Ask either guard which door the other guard would call safe, then take the opposite door
Asking about a door directly cannot work, since you never learn who you are talking to. Asking what the other guard would say makes both of them name the same bad door, so you take the other.

72. There is a part of your body you can easily hold in your left hand, yet you can never hold it in your right hand. What is it? Hard
Most people first say: Your left elbow
Need a hint?
You are using the wrong arm entirely.
Show answer
Your right elbow
The pair of hands is the whole puzzle: whatever the answer is, it has to sit on the right arm itself. Reaching across works, and reaching back along the same limb does not.

73. What has a neck but no head, and can wear a cap without a single hair? Easy
Most people first say: A shirt
Show answer
A bottle
Neck and cap belong to a person until you notice what is missing: no head, no hair. Both words also name parts of a container, and one of them screws on.
-
74. What has plenty of teeth in a row but has never once taken a bite? Easy
Most people first say: A saw blade
Show answer
A comb
Teeth without biting is the mismatch to solve. Rows of thin points that never chew belong on a grooming tool, not in a mouth, and hair is what they move.
-
75. What has one thumb and four fingers yet is not alive? Easy
Show answer
A glove
Counting five digits sends you straight to a hand, and not alive rules that out. Something shaped like a hand that stays empty until you fill it is clothing, worn in winter.
-
76. What is full of holes all over yet still manages to hold water? Easy
Show answer
A sponge
Holes usually mean leaks, and that expectation is the whole riddle. Tiny pockets can trap liquid instead of letting it run out, which is why a kitchen keeps one by the sink.
-
77. What is packed with words on every page but never says a thing out loud? Easy
Show answer
A book
Words on a page suggest a voice, and never says a thing takes the voice away. What is left is a silent object you read, stacked with pages instead of speech.

FAQ about Famous and Classic Riddles
What is the most famous riddle of all time?
The riddle of the Sphinx is the usual answer: what walks on four legs in the morning, two at noon, and three in the evening. It opens this collection, along with a trivia question about what happened to the Sphinx after Oedipus solved it.
Which of these famous riddles is the oldest?
Samson's riddle about honey from the lion is the oldest one here with a written source, since it sits in the Book of Judges. The Sphinx pair, the Exeter Book bookworm, and the Norse riddle about hooded maidens follow it, and one multiple choice card asks which civilization left the earliest riddle tablets of all.
Why is a raven like a writing desk?
Lewis Carroll never meant that one to have an answer. The Mad Hatter asks it in Alice's Adventures in Wonderland and admits he has none, and years later Carroll offered one in a preface, saying a raven can produce a few notes, though they are very flat. A card on this page asks who poses the question.
Can I use these famous riddles in a classroom?
They fit history and literature lessons well, since many connect directly to texts students meet anyway. Most are solvable by middle schoolers, and every answer reveals on tap so you can run the page as a group quiz.
Knowing where a classic came from is half the fun of retelling it, so read the origin line where one is given before you pass the riddle on. When you want the same tricks in costume, the Riddler riddles from Batman lean just as hard on wordplay, and the lateral thinking puzzles hand you a scene to question instead of an object to name.
