Every question, answer and explanation

Warm-Up

  1. What has keys but can't open a single lock?

    Answer A piano

    The trick is that "key" splits two ways: the thing that turns a lock, and the thing you press. A piano has eighty-eight of the second kind and none of the first.

  2. What gets wetter the more it dries?

    Answer A towel

    Drying is one act with two sides — the towel takes on the water it removes. "Dries" pushes you toward getting drier, when the verb here means what it does to you, not to itself.

  3. What has to be broken before you can use it?

    Answer An egg

    Most things break when they stop being useful, so the riddle sounds like a contradiction. An egg is the reverse: the shell is packaging, and breaking is how you open it.

  4. What goes up but never comes down?

    Answer Your age

    You picture a thrown ball, so gravity feels like part of the question. Age only counts upward — nothing is going anywhere, so nothing has to come back down.

  5. What has a face and two hands but no arms or legs?

    Answer A clock

    "Face" and "hands" both belong to a body, which is why the pair reads as a person. On a clock both words are old technical names for parts, and neither implies the rest of a body.

  6. What has one eye but cannot see?

    Answer A needle

    An eye is for seeing, so the word smuggles in a creature. A needle's eye is named for its shape — a small round opening — and shape is all the two share.

  7. What has a neck but no head?

    Answer A bottle

    Necks come attached to heads, so the riddle borrows that expectation. On a bottle the neck is the narrow part below the opening, named by resemblance and nothing else.

  8. What is full of holes but still holds water?

    Answer A sponge

    Holes are how containers fail, which makes "holds water" sound impossible. A sponge holds water in the holes rather than in spite of them — surface tension keeps it there.

  9. What has teeth but cannot bite?

    Answer A comb

    Teeth suggest a mouth, and a mouth suggests biting. A comb's teeth are a row of thin projections; the name describes the arrangement, not what it does.

  10. What kind of band never plays music?

    Answer A rubber band

    "Band" means a group of musicians and also a loop of material. The riddle leans on the first meaning by mentioning music, then answers with the second.

Curious Objects

  1. What can travel around the world while staying in a corner?

    Answer A stamp

    A corner sounds like a place you are stuck in. The stamp's corner travels with the envelope, so staying in one corner and crossing the world are not in conflict at all.

  2. What building has the most stories?

    Answer A library

    A "story" is a floor of a building and also a thing you read. The riddle asks in the language of architecture and answers in the language of books.

  3. What invention lets you look right through a wall?

    Answer A window

    You expect a gadget, because "invention" and "look right through" sound like technology. A window is the plainest possible answer and has been the answer for centuries.

  4. What has words but never speaks?

    Answer A book

    Words normally arrive as speech, so "has words" pulls toward a speaker. A book holds them without ever producing a sound — the words are stored, not spoken.

  5. What has a thumb and four fingers but is not alive?

    Answer A glove

    One thumb and four fingers is the exact shape of a hand, so the mind fills in a person. A glove is that shape and nothing more, which is the whole point of it.

  6. What kind of room has no doors or windows?

    Answer A mushroom

    This one hides in the spelling: "mushroom" ends in the letters r-o-o-m without containing a room. The question asks about architecture and the answer is a fungus.

  7. What runs all around a garden but never moves?

    Answer A fence

    "Runs" is doing double duty. Applied to a path or a boundary it means extends along, with no motion implied — a fence runs around a garden while standing still.

  8. What has legs but doesn't walk?

    Answer A table

    Legs imply walking because we meet them on animals first. Furniture borrows the word for anything that holds a body up off the ground.

  9. What has one head, one foot and four legs?

    Answer A bed

    The head and foot of a bed are named for where the sleeper's head and feet go, not for parts the bed has. Once you hear them as positions, the four legs stop being strange.

  10. What goes through towns and over hills but never moves?

    Answer A road

    Same trick as the fence, stretched further. "Goes through towns and over hills" describes the road's shape across a map, and shape does not require movement.

Wordplay

  1. What month of the year has 28 days?

    Answer All of them

    February is the one with only 28, and the riddle counts on you hearing "only." Every month reaches a 28th, so every month has 28 days in it.

  2. Where does today come before yesterday?

    Answer In a dictionary

    The question sounds like it is about time, so you look for a paradox. Alphabetical order is a different order entirely, and in it "today" simply lands before "yesterday."

  3. What begins with T, ends with T, and has T in it?

    Answer A teapot

    You look for a spelling puzzle, and there is one, but it works on two levels at once: the word starts and ends with the letter T, and the pot has tea in it.

  4. What five-letter word becomes shorter when you add two letters?

    Answer Short

    Adding letters normally makes a word longer, so the riddle sounds self-defeating. "Short" plus e-r becomes "shorter" — the word gets longer while its meaning gets smaller.

  5. Which word is spelled incorrectly in every dictionary?

    Answer Incorrectly

    You start hunting for a typo that every dictionary shares. There is none: "incorrectly" is spelled correctly, and it is also the word that means what the question asks about.

  6. What starts with an E, ends with an E, but contains only one letter?

    Answer An envelope

    "Only one letter" makes you count the letters in a word. An envelope contains a letter in the postal sense, which is a different meaning of the same word.

  7. I am an odd number. Take away a letter and I become even. What am I?

    Answer Seven

    The riddle says odd and even, so you reach for arithmetic. Removing the letter S turns "seven" into "even" — the change is in the spelling, not the number.

  8. What word looks the same upside down and backwards?

    Answer SWIMS

    In capitals, S and W and I and M each survive a half-turn, and the word's order reverses to itself at the same time. Both symmetries have to hold, which is why so few words qualify.

  9. What two things can you never eat for breakfast?

    Answer Lunch and dinner

    You search for foods, because "eat" points at the plate. The answer is about the meal's name instead — whatever you eat first is breakfast by definition.

  10. What word of four letters can be written forward, backward or upside down, and still be read from left to right?

    Answer NOON

    Reversed it is still NOON, and in capitals each letter is its own mirror. That is why it survives being turned upside down as well as backward.

Everyday Logic

  1. If you overtake the runner in second place, what place are you in?

    Answer Second

    The pull is to say first, because overtaking feels like winning. You took the second runner's place, so second is exactly what you inherit.

  2. What can you catch but not throw?

    Answer A cold

    "Catch" has a sporting sense and a medical one, and the riddle sets up the first so the second lands. You catch a cold without anyone throwing it.

  3. What can't talk but will always reply when spoken to?

    Answer An echo

    Replying implies a speaker, so you look for something that understands you. An echo returns your own sound, which answers the letter of the question and none of its spirit.

  4. What is always in front of you but can't be seen?

    Answer The future

    "In front of you" sounds spatial, so you scan the room. Time uses the same word — we speak of what lies ahead — and nothing ahead in that sense is visible.

  5. What gets bigger the more you take away from it?

    Answer A hole

    Taking away normally shrinks things, which is what makes this feel impossible. A hole is defined by what is absent, so removing more material is exactly how it grows.

  6. The more of it there is, the less you see. What is it?

    Answer Darkness

    More of a thing usually means more to look at. Darkness is the one substance whose quantity is measured by how much it removes.

  7. What goes up and down but stays in the same place?

    Answer Stairs

    Going up and down sounds like travel, so you think of elevators or yo-yos. Stairs go up and down as a description of their shape, the way a road runs over a hill.

  8. What belongs to you but is used more by others?

    Answer Your name

    Ownership suggests something you hold, so you look for an object. Your name is yours and yet almost every use of it is by someone else, addressing you.

  9. What has ears but cannot hear?

    Answer A cornfield

    An ear of corn is named for its shape on the stalk, an old use of the word unrelated to hearing. A field of it has thousands of ears and no hearing at all.

  10. What runs but never walks, has a mouth but never talks?

    Answer A river

    "Runs" and "mouth" are both borrowed from bodies. A river runs in the sense of flowing, and its mouth is where it meets the sea — geography took the words and dropped the body.

Hard Mode

  1. A man in a house couldn't see out, and there were no doors or windows he could use. How did he get out? He stopped...

    Answer Imagining — it was a dream

    The riddle is built so that no physical answer can work: no doors, no windows, no way out. The escape is to notice the room was never real.

  2. The person who makes it sells it. The person who buys it never uses it. What is it?

    Answer A coffin

    You look for something useless, since the buyer never uses it. The buyer is not the occupant — that gap between purchaser and user is the whole riddle.

  3. What is so fragile that saying its name breaks it?

    Answer Silence

    Fragile suggests glass, so you think about physical breaking. Silence is the one thing the act of naming destroys, because naming it makes a sound.

  4. Forward I am heavy, backward I am not. What am I?

    Answer The word 'ton'

    "Heavy" points you at weight, and there is a weight in it, but only as spelling. Reverse the letters of "ton" and you get "not" — heavy read one way, negation read the other.

  5. What can fill a room but takes up no space?

    Answer Light

    Filling a room implies volume, so you think of water or air. Light fills a room in the sense of reaching every part of it while displacing nothing.

  6. I have cities but no houses, forests but no trees, rivers but no water. What am I?

    Answer A map

    Each pair sounds like a contradiction until you notice they all fail the same way: the map has the names and shapes of these things, never the things.

  7. What comes once in a minute, twice in a moment, but never in a thousand years?

    Answer The letter M

    You hear the words as durations, so you start comparing spans of time. The riddle is counting letters instead — one M in "minute," two in "moment," none in "thousand years."

  8. If two's company and three's a crowd, what are four and five?

    Answer Nine

    The saying about company and crowds sets you up to answer with a phrase. The question is arithmetic in disguise: four and five is nine.

  9. What has 13 hearts but no other organs?

    Answer A deck of cards

    Hearts and organs put you in a body, so the count sounds anatomical. There are thirteen cards in the suit of hearts, and a deck has no anatomy at all.

  10. The more you take, the more you leave behind. What are they?

    Answer Footsteps

    Taking usually reduces what is left, which is why this sounds backward. Steps are the exception — each one you take is one more left behind you.

About Riddles

Riddles are the oldest quiz format there is, and the only one that tests nothing you have learned. A riddle does not ask what you know; it asks whether you can hear a word in two ways at once — whether, when told about keys that open no locks, you can let go of doors long enough to think of a piano.

This set collects fifty classic brain teasers in five rounds of ten: a warm-up, curious objects, wordplay, everyday logic and hard mode. Each has four options with the solution revealed as you pick, which is a kinder format than the traditional one. With a riddle spoken aloud you either see it or sit in silence; with four options in front of you, the answer usually reveals itself the moment you read it, and that small click of recognition is the whole pleasure of the form.

These are the classics rather than newly invented puzzles, and that is on purpose. A riddle survives centuries because its misdirection still works on people who have heard hundreds of others — the sentence sends you down the wrong road every time, even after you know the road is wrong. A good number of these were already being asked a century ago.

How it works
  1. Read the riddle twice before you look at the options. Hurrying does nothing here — it only makes the wrong road more convincing.
  2. The solution appears as you choose. With riddles the laugh arrives after the answer rather than before it, so the screen waits while you groan; tap anywhere when you are done.
  3. The rounds get harder in order — the warm-up is meant to be solved, hard mode is meant to be missed a few times.
  4. There is a score out of fifty at the end, counted by round, though with riddles the number matters far less than which three you now want to try on somebody else.
  5. All fifty riddles and their solutions are written out below — that is the version to use for reading aloud rather than tapping — and a finished run marks the ones that got you.

Frequently asked questions

My answer works too. Why is it marked wrong?

Riddles produce workable alternate answers more often than any other kind of question, because a good riddle is deliberately ambiguous and a clever solver can always find a second reading that fits. The four options are chosen so that only one matches the traditional answer, and that traditional answer is the one marked correct. If your reading is genuinely better, you have out-riddled the riddle, which is a respectable result.

Why multiple choice instead of typing an answer?

Because a typed answer would have to be marked by spelling, and riddles rarely have one exact wording. Options also keep the game moving: nobody wants to stare at a blank box for four minutes. The trade is that some riddles are easier to solve backwards from the list, which is why the last round hides its answer among options that all look plausible.

Are these suitable for children?

The first three rounds are — they are the riddles that circulate in playgrounds, and children are often faster at them than adults, having fewer fixed assumptions to unlearn. The logic and hard rounds assume a bit more patience. Nothing in the set is frightening or unsuitable in any way.

Does being bad at riddles mean anything?

It means you take language at its word, which in almost every other situation is a virtue. Riddle-solving is a narrow trick of loosening a sentence, and it is not a measure of intelligence, reasoning or wit. Anyone who does a few dozen gets noticeably better, which tells you what kind of skill it really is.

Why do I already know some of these?

Because they are classics. This is a collection of the riddles that endured, not a set of new inventions, and the endurance is the point — a riddle nobody remembers was not a very good riddle. If you know a third of them already, you will find they still work on the friend you try them on tonight.

Are the Riddles free, and do I need an account?

Free, with no account and no email. The fifty riddles and their answers are on the page from the moment it loads, and nothing you tap leaves the tab or is sent anywhere — which matters here, because the pleasure of a riddle survives badly under anything that keeps a record of you.

How long do the Riddles take, and can I do them with someone else?

About eight minutes alone, and longer in the good way with someone else — riddles are the one format where saying a wrong idea out loud actually helps. The four options mean you never argue about spelling, only about which reading of the sentence was the intended one.
