Riddles for Teens: 48 Tricky Riddles With Answers
Here are 48 riddles for teens with answers, each answer on its own line so you can cover it and guess first. They are pitched at roughly ages 13 to 18: harder than kids' riddles, less punishing than the ones written to stump adults, and sorted by the kind of thinking each one needs.
The tricky riddles hide a false assumption. The high school set needs a little logic or arithmetic. The funny riddles are puns, the word riddles depend on spelling, and the last set is a connection puzzle with no stock answer to look up. A short note after many answers explains why the riddle works, which is the part worth talking about in a classroom or group chat.
Tricky Riddles for Teens
Each of these leans on something you assume without noticing. If you're stuck, read the question again slowly and ask which word you've taken for granted.
1. On her last birthday a girl was 10. On her next birthday she'll be 12. How?
Answer: Today is her 11th birthday.
Why it works: "Last" and "next" sound as if they sit on either side of today. When today is the birthday, they don't.
2. Is it legal for a man to marry his widow's sister?
Answer: No. If he has a widow, he's dead.
Why it works: You start thinking about marriage law and never reach the word "widow."
3. Can a man who lives in New York be buried west of the Mississippi?
Answer: No. He's still living.
Why it works: The geography question pulls attention away from "lives."
4. How many birthdays does the average person have?
Answer: One. You're only born once. Every year after that is an anniversary of it.
5. You walk into a dark cabin carrying one match. Inside are a candle, an oil lamp and a fireplace. What do you light first?
Answer: The match.
Why it works: The list of three options makes you choose among them, so the fourth thing in the scene disappears.
6. A one-story house is painted yellow inside and out: yellow walls, yellow floors, yellow furniture. What color are the stairs?
Answer: There are no stairs. It's a one-story house.
7. You throw me out when you want to use me and pull me back in when you're done. What am I?
Answer: An anchor.
8. Poor people have it. Rich people need it. If you eat it, you die. What is it?
Answer: Nothing.
Why it works: Read each line with "nothing" in place of "it" and every clue is literally true.
9. A man shaves several times a day, yet he still has a beard. How?
Answer: He's a barber. He shaves other people.
10. What tastes better than it smells?
Answer: Your tongue.
Why it works: You go looking for a food. The answer is the thing doing the tasting.
Riddles for High School Students
These need a bit of logic or quick arithmetic, so they suit a math or science warm-up. Give two minutes each and ask students to show how they know, not just what they got.
11. What is half of two plus two?
Answer: Three. Half of two is one, and one plus two is three.
Why it works: Most people hear "half of (two plus two)" and say two. Order of operations says otherwise. Ask the class how they would rewrite the question to make it mean two.
12. Divide 30 by half and add 10. What do you get?
Answer: 70. Dividing by one half is the same as multiplying by two, so 30 becomes 60, and 60 plus 10 is 70.
Why it works: "Divide by half" gets heard as "divide in half," which gives 25.
13. A clock reads 3:15. What is the angle between the hour hand and the minute hand?
Answer: 7.5 degrees.
Why it works: The minute hand points straight at the 3, but the hour hand has moved a quarter of the way from 3 to 4. Each hour mark is 30 degrees apart, and a quarter of 30 is 7.5.
14. How many times do the hour and minute hands of a clock overlap in 24 hours?
Answer: 22.
Why it works: Every 12 hours the minute hand laps the hour hand 11 times, not 12, because there is no overlap between 11:00 and 12:00 apart from 12:00 itself. Twice 11 is 22.
15. Take any two-digit number whose digits are different. Reverse the digits and subtract the smaller number from the larger one. Which number will always divide evenly into the result?
Answer: 9. For example, 72 minus 27 is 45, and 91 minus 19 is 72.
Why it works: A two-digit number with digits a and b is worth 10a plus b. Reversed, it's 10b plus a. The difference is 9 times (a minus b), so it is always a multiple of 9.
16. A father is four times as old as his son. In 20 years he'll be only twice as old. How old are they now?
Answer: The son is 10 and the father is 40. In 20 years they'll be 30 and 60.
17. If a hen and a half lays an egg and a half in a day and a half, how many eggs does one hen lay in one day?
Answer: Two thirds of an egg.
Why it works: One and a half hens make one and a half eggs in a day and a half, so one hen makes one egg in a day and a half. In a single day that's two thirds of an egg. The quick answer, "one," treats three changes as if they cancel out.
18. Two books stand side by side on a shelf in the usual way, Volume 1 on the left, spines facing you. Each book's pages are 2 inches thick and each cover is a quarter of an inch thick. A bookworm starts at the first page of Volume 1 and chews in a straight line to the last page of Volume 2. How far does it travel?
Answer: Half an inch: just the front cover of Volume 1 and the back cover of Volume 2.
Why it works: With the spines facing out, page 1 of Volume 1 sits on its right-hand side, next to Volume 2, and the last page of Volume 2 sits on its left-hand side. The worm never goes through the pages at all.
Funny Riddles for Teens
Every one of these is a pun. They work well as a group-chat riddle of the day, because the groan is half the fun. For a longer set, the funny riddles collection has 60 more.
19. What do you call a group of whales playing instruments?
Answer: An orca-stra.
20. What did the calculator say to the student before the test?
Answer: "You can count on me."
21. Why was the broom late for school?
Answer: It over-swept.
22. Why did the teenager take a ruler to bed?
Answer: To see how long they slept.
23. Why couldn't the pony sing in the school choir?
Answer: It was a little hoarse.
24. What do you call a sad cup of coffee?
Answer: Depresso.
25. What do you call a bear with no ears?
Answer: B.
26. How does the moon get its hair cut?
Answer: Eclipse it.
What Am I? Riddles for Teens
In these the answer describes itself in clues that sound impossible until you see it. Read the whole riddle before guessing, since the last clue usually settles it.
27. I sit in your pocket all day. My face lights up when someone wants you, I wake you up in the morning, and I die if you forget to feed me at night. What am I?
Answer: A phone.
28. I have the head of a cat, the feet of a cat and the tail of a cat, but I'm not a cat. What am I?
Answer: A kitten.
29. I can be cracked, made, told and played. What am I?

30. I'm taken from a mine and shut up in a wooden case that I never leave, yet almost everyone uses me. What am I?

31. I have to be answered, but I never ask a question. What am I?
Answer: A doorbell.
32. I go through cities and across fields, but I never move. What am I?

33. I'm always on my way, but I never arrive. What am I?
Answer: Tomorrow. Once it gets here, it's today.
34. The more you use me, the sharper I get. What am I?
Answer: Your mind.
Word Riddles for Teens
These are about the letters, not the meaning. When a word riddle won't crack, write the key words down and look at them.
35. What has four eyes but can't see?
Answer: Mississippi. It has four i's.
36. What can you find in the middle of March and April that you can't find at the start or end of either month?
Answer: The letter R.
37. Which letter of the alphabet holds the most water?
Answer: C (the sea).
38. Why is the letter T like an island?
Answer: Because it's in the middle of "water."
39. What has four letters, sometimes has nine, and never has five?
Answer: The riddle is describing its own words. "What" has four letters, "sometimes" has nine, and "never" has five, so the statement is true of the sentence, not of any object.
Why it works: It is the hardest one here because there's no object to find. Most people need the hint "count the letters."
40. "Level," "radar" and "civic" belong together. Which word for the middle of the day belongs with them, and why?
Answer: "Noon." All four read the same forward and backward (they're palindromes).
Connection Riddles for Teens
Each set has three words. Find one word that goes with all three to make a compound word or common phrase. This is the format of the Remote Associates Test, a puzzle used in research on creative thinking, and it's a good set for teens who already know the classic riddles, because there's nothing to remember. Try saying guesses out loud: "Is it 'light'? Flashlight, backlight, spotlight. Yes."
41. cottage, Swiss, cake
Answer: Cheese (cottage cheese, Swiss cheese, cheesecake)
42. cream, skate, water
Answer: Ice (ice cream, ice skate, ice water)
43. show, life, row
Answer: Boat (showboat, lifeboat, rowboat)
44. duck, fold, dollar
Answer: Bill (duckbill, billfold, dollar bill)
45. flash, back, spot
Answer: Light (flashlight, backlight, spotlight)
46. selfie, walking, candle
Answer: Stick (selfie stick, walking stick, candlestick)
47. lunch, tool, shoe
Answer: Box (lunchbox, toolbox, shoebox)
48. pass, zip, area
Answer: Code (passcode, zip code, area code)
How to Use These Riddles With Teens
Teenagers can smell an activity that's meant to be good for them. These formats keep the riddles competitive and quick, which is what makes them work.
Silent first guess (5 minutes). Put one riddle on the board as the class walks in. Everyone writes an answer on scrap paper before anyone speaks, so the fastest student doesn't end it for the rest of the room. Reveal it after three minutes and ask one student who got it to explain why it works.
Riddle duel (10 minutes). Split into two teams. Each team gets 60 seconds per riddle, with one point for the answer and a bonus point for explaining it. Mix sections so the logic fans and the pun fans both get their moment. The high school set (11 to 18) makes a good tiebreak round.
Riddle of the day (1 minute a day). Post one riddle in a family or class group chat each morning and the answer the next. It takes no setup, and the tricky riddles (1 to 10) are short enough to read on a phone.
Defend the wrong answer (10 minutes). After a tricky riddle is solved, ask students to argue for the most common wrong answer and pin down exactly where it breaks. Doing this for "half of two plus two" or the hen and a half turns a riddle into a lesson on reading a question carefully. Teachers who want more of this can borrow from the critical thinking questions list.
Match the set to the group. Younger teens who find these hard can warm up with the brain teasers for middle school. Teens who solve everything here are ready for the hard riddles, which are written to stump adults, or the longer mysteries in lateral thinking puzzles, where the group solves the puzzle by asking yes-or-no questions.
How Teens Can Write Their Own Riddles
Writing a riddle is harder than solving one, and that's the point: you have to see an ordinary thing from an angle nobody expects. This takes about 15 minutes.
- Pick an object (1 minute). Choose something everyone in the room uses: headphones, a locker, a backpack, a charger.
- List its parts and jobs (4 minutes). Write every part with a name and everything the object does. Headphones have a band, ear cups and a cord; they play, block noise and tangle.
- Find the double meanings (5 minutes). Circle any part or job that also describes a person, animal or feeling. A charger "feeds" a phone. A locker has a "combination."
- Write three clues (3 minutes). Turn the double meanings into clues that sound impossible, and save the most revealing clue for last.
- Test it (2 minutes). Try it on a friend. If they get it in under five seconds, make a clue harder. If no one gets it with a hint, one clue is unfair.
For a harder version, write a connection riddle like 41 to 48. The test is whether only one word fits all three cues; if two answers work, swap a cue.
Keep Practicing With Fresh Puzzles
A riddle only works once. When you know the answer, it's spent. Connection riddles are different, because the same kind of thinking works on new words every time.
Our Speed Connections drill is built on that format. You see three cue words and type the one word that connects them. A correct answer moves you to the next triad, and wrong guesses or skips add strikes, up to three. You set the length of the timer before you start, so a five-minute round fits at the start of a class or the end of a study session. Teens who like the word riddles can also try the word brain teasers, and anyone younger in the house can start with the riddles for kids.
Frequently Asked Questions
What are good riddles for teens?
Good riddles for teens are hard enough to need a second look but fair once you see the answer. Tricky riddles that hide a false assumption, such as "Is it legal for a man to marry his widow's sister?", and short logic riddles, such as "Divide 30 by half and add 10," work especially well with this age group.
What age are these riddles for?
They suit roughly ages 13 to 18. The funny and what-am-I riddles work for younger teens, and the high school set (11 to 18) suits ages 15 and up, since a few need comfort with fractions and order of operations.
What is the hardest riddle on this list?
Most people find riddle 39 the hardest ("What has four letters, sometimes has nine, and never has five?") because there's no object to find. The bookworm riddle (18) is a close second, since it depends on picturing how books sit on a shelf.
How do you use riddles in a high school classroom?
Use one as a silent warm-up: students write a guess before anyone speaks, then one student explains the answer. A riddle duel between two teams, with a bonus point for explaining the answer, fits into 10 minutes at the end of a lesson.
What is the difference between a riddle and a brain teaser?
A riddle is usually a question with a hidden double meaning or false assumption, and the answer clicks once you spot it. A brain teaser is a broader term that includes logic and math puzzles you work through step by step. The high school set here sits in between.
How can teens get better at solving riddles?
Read the question twice and name the assumption you're making, then try the opposite. Saying guesses out loud also helps, especially for connection riddles. Practice with new puzzles rather than ones you've seen, because a remembered answer trains nothing.
