Einstein’s Hard Riddle 

Now, if you’re really up for a challenge, here is Albert Einstein’s riddle , one that is believed to be developed when he was young. The best way to find the answer to this brain teaser is through logic and deductive reasoning.

Hard Mythology Riddle  

There is a mythological story of a Sphinx, a monster with the body of a lion and the head of a woman. Apparently, the Sphinx sat on top of a rock along the road to the city of Thebes, stopping travelers and proposing to them a riddle . The Sphinx claimed that whoever failed the riddle would be killed, and evidently, not pass through to the city. 

This is the riddle : 

What animal walks on four legs in the morning, two legs during the day, and three legs in the evening?

Oedipus, the king of Thebes, figured out the answer to the riddle :

Man, who in childhood creeps on hands and knees, in manhood walks erect, and in old age with the aid of a staff. (Morning, day and night are representative of the stages of life.)

Riddle No. 1: The King’s Orders Make for One Hell of a Brain Teaser

Difficulty: easy.

King Nupe of the kingdom Catan dotes on his two daughters so much that he decides the kingdom would be better off with more girls than boys, and he makes the following decree: All child-bearing couples must continue to bear children until they have a daughter!

But to avoid overpopulation, he makes an additional decree: All child-bearing couples will stop having children once they have a daughter! His subjects immediately begin following his orders.

After many years, what’s the expected ratio of girls to boys in Catan?

The likelihood of each baby born being a girl is, of course, 50 percent.

Riddle No. 2: How Many Eggs Does This Hen Lay?

This problem is in honor of my dad, Harold Feiveson. It’s due to him that I love math puzzles, and this is one of the first problems (of many) that he gave me when I was growing up.

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?

Riddle No. 3: The Gold Chain Math Problem Is Deceptively Simple

Difficulty: moderate.

You’re rummaging around your great grandmother’s attic when you find five short chains each made of four gold links. It occurs to you that if you combined them all into one big loop of 20 links, you’d have an incredible necklace. So you bring it into a jeweler, who tells you the cost of making the necklace will be $10 for each gold link that she has to break and then reseal.

How much will it cost?

Riddle No. 4: Try to Solve This Pickleball Puzzle

Difficulty: 🚨hard🚨.

Kenny, Abby, and Ned got together for a round-robin pickleball tournament, where, as usual, the winner stays on after each game to play the person who sat out that game. At the end of their pickleball afternoon, Abby is exhausted, having played the last seven straight games. Kenny, who is less winded, tallies up the games played:

Kenny played eight games

Abby played 12 games

Ned played 14 games

Who won the fourth game against whom?

How many total games were played?

Riddle No. 5: Our Circuit Breaker Riddle Is Pure Evil. Sorry.

The circuit breaker box in your new house is in an inconvenient corner of your basement. To your chagrin, you discover none of the 100 circuit breakers is labeled, and you face the daunting prospect of matching each circuit breaker to its respective light. (Suppose each circuit breaker maps to only one light.)

To start with, you switch all 100 lights in the house to “on,” and then you head down to your basement to begin the onerous mapping process. On every trip to your basement, you can switch any number of circuit breakers on or off. You can then roam the hallways of your house to discover which lights are on and which are off.

What is the minimum number of trips you need to make to the basement to map every circuit breaker to every light?

The solution does not involve either switching on or off the light switches in your house or feeling how hot the lightbulbs are. You might want to try solving for the case of 10 unlabeled circuit breakers first.

Riddle No. 6: Two Trains. Two Grandmas. Can You Solve This Tricky Math Riddle?

Jesse’s two grandmothers want to see him every weekend, but they live on opposite sides of town. As a compromise, he tells them that every Sunday, he’ll head to the subway station nearest to his apartment at a random time of the day and will hop on the next train that arrives.

If it happens to be the train traveling north, he’ll visit his Grandma Erica uptown, and if it happens to be the train traveling south, he’ll visit his Grandma Cara downtown. Both of his grandmothers are okay with this plan, since they know both the northbound and southbound trains run every 20 minutes.

But after a few months of doing this, Grandma Cara complains that she sees him only one out of five Sundays. Jesse promises he’s indeed heading to the station at a random time each day. How can this be?

The trains always arrive at their scheduled times.

Riddle No. 7: Here’s a Really F@*#ing Hard Math Problem About Ants

Max and Rose are ant siblings. They love to race each other, but always tie, since they actually crawl at the exact same speed. So they decide to create a race where one of them (hopefully) will win.

For this race, each of them will start at the bottom corner of a cuboid, and then crawl as fast as they can to reach a crumb at the opposite corner. The measurements of their cuboids are as pictured:

ant riddle

If they both take the shortest possible route to reach their crumb, who will reach their crumb first? (Don’t forget they’re ants, so of course they can climb anywhere on the edges or surface of the cuboid.)

Remember: Think outside the box.

Riddle No. 8: This Peppermint Patty Riddle Is Practically Impossible

You’re facing your friend, Caryn, in a “candy-off,” which works as follows: There’s a pile of 100 caramels and one peppermint patty. You and Caryn will go back and forth taking at least one and no more than five caramels from the candy pile in each turn. The person who removes the last caramel will also get the peppermint patty. And you love peppermint patties.

Suppose Caryn lets you decide who goes first. Who should you choose in order to make sure you win the peppermint patty?

First, solve for a pile of 10 caramels.

Riddle No. 9: Can You Solve the Great American Rail-Trail Riddle?

This problem was suggested by the physicist P. Jeffrey Ungar.

Finally, the Great American Rail-Trail across the whole country is complete! Go ahead, pat yourself on the back—you’ve just installed the longest handrail in the history of the world, with 4,000 miles from beginning to end. But just after the opening ceremony, your assistant reminds you that the metal you used for the handrail expands slightly in summer, so that its length will increase by one inch in total.

“Ha!” you say, “One inch in a 4,000 mile handrail? That’s nothing!” But … are you right?

Let’s suppose when the handrail expands, it buckles upward at its weakest point, which is in the center. How much higher will pedestrians in the middle of the country have to reach in summer to grab the handrail? That is, in the figure below, what is h ? (For the purposes of this question, ignore the curvature of the Earth and assume the trail is a straight line.)

great american rail trail riddle

Pythagoras is a fascinating historical figure.

Riddle No. 10: This Riddle Is Like an Especially Cruel SAT Problem. Can You Find the Answer?

Amanda lives with her teenage son, Matt, in the countryside—a car ride away from Matt’s school. Every afternoon, Amanda leaves the house at the same time, drives to the school at a constant speed, picks Matt up exactly when his chess club ends at 5 p.m., and then they immediately return home together at the same constant speed. But one day, Matt isn’t feeling well, so he leaves chess practice early and starts to head home on his portable scooter.

After Matt has been scooting for an hour, Amanda comes across him in her car (on her usual route to pick him up), and they return together, arriving home 40 minutes earlier than they usually do. How much chess practice did Matt miss?

Consider the case where Amanda meets Matt exactly as she’s leaving their house.

Riddle No. 11: Can You Get These 3 Movie Stars Across the River?

Three movie stars, Chloe, Lexa, and Jon, are filming a movie in the Amazon. They’re very famous and very high-maintenance, so their agents are always with them. One day, after filming a scene deep in the rainforest, the three actors and their agents decide to head back to home base by foot. Suddenly, they come to a large river.

On the riverbank, they find a small rowboat, but it’s only big enough to hold two of them at one time. The catch? None of the agents are comfortable leaving their movie star with any other agents if they’re not there as well. They don’t trust that the other agents won’t try to poach their star.

For example, Chloe’s agent is okay if Chloe and Lexa are alone in the boat or on one of the riverbanks, but definitely not okay if Lexa’s agent is also with them. So how can they all get across the river?

There isn’t just one way to solve this problem.

Riddle No. 12: This Ludicrously Hard Riddle Is Our Tribute to a Late Math Genius. Can You Figure It Out?

On April 11, John Horton Conway , a brilliant mathematician who had an intense and playful love of puzzles and games, died of complications from COVID-19. Conway is the inventor of one of my favorite legendary problems (not for the faint of heart) and, famously, the Game of Life . I created this problem in his honor.

Carol was creating a family tree, but had trouble tracking down her mother’s birthdate. The only clue she found was a letter written from her grandfather to her grandmother on the day her mother was born. Unfortunately, some of the characters were smudged out, represented here with a “___” . (The length of the line does not reflect the number of smudged characters.)

“Dear Virginia,

Little did I know when I headed to work this Monday morning, that by evening we would have a beautiful baby girl. And on our wedding anniversary, no less! It makes me think back to that incredible weekend day, J___ 27th, 19___ , when we first shared our vow to create a family together, and, well, here we are! Happy eighth anniversary, my love.

Love, Edwin”

The question: When was Carol’s mother born?

This problem is inspired by Conway’s Doomsday Rule .

Riddle No. 13: To Solve This Twisty Math Riddle, You Just Need One Belt and One Earth

Imagine you have a very long belt. Well, extremely long, really … in fact, it’s just long enough that it can wrap snugly around the circumference of our entire planet. (For the sake of simplicity, let’s suppose Earth is perfectly round, with no mountains, oceans, or other barriers in the way of the belt.)

Naturally, you’re very proud of your belt. But then your brother, Peter, shows up—and to your disgruntlement, he produces a belt that’s just a bit longer than yours. He brags his belt is longer by exactly his height: 6 feet.

If Peter were also to wrap his belt around the circumference of Earth, how far above the surface could he suspend the belt if he pulled it tautly and uniformly?

Earth’s circumference is about 25,000 miles, or 130 million feet … but you don’t need to know that to solve this problem.

Riddle No. 14: This Elbow Tapping Riddle Is Diabolical. Good Luck Solving It.

In some future time, when the shelter-in-place bans are lifted, a married couple, Florian and Julia, head over to a bar to celebrate their newfound freedom.

They find four other couples there who had the same idea.

Eager for social contact, every person in the five couples enthusiastically taps elbows (the new handshake) with each person they haven’t yet met .

It actually turns out many of the people had known each other prior, so when Julia asks everyone how many elbows they each tapped, she remarkably gets nine different answers!

The question: How many elbows did Florian tap?

What nine answers did Julia hear?

Riddle No. 15: You’ll Need a Drink After Trying to Solve This Whisky Riddle

Alan and Claire live by the old Scottish saying, “Never have whisky without water, nor water without whisky!” So one day, when Alan has in front of him a glass of whisky, and Claire has in front of her a same-sized glass of water, Alan takes a spoonful of his whisky and puts it in Claire’s water. Claire stirs her whisky-tinted water, and then puts a spoonful of this mixture back into Alan’s whisky to make sure they have exactly the same amount to drink.

So: Is there more water in Alan’s whisky, or more whisky in Claire’s water? And does it matter how well Claire stirred?

The size of the spoon does not matter.

Riddle No. 16: The Doodle Problem Is a Lot Harder Than It Looks. Can You Solve It?

This week’s riddle is relatively simple—but sinister all the same.

The question: Can you make 100 by interspersing any number of pluses and minuses within the string of digits 9 8 7 6 5 4 3 2 1? You can’t change the order of the digits! So what’s the least number of pluses and minuses needed to make 100?

Text, Font, Logo, Graphics, Smile,

For instance, 98 - 7 - 6 + 54 - 32 shows one way of interspersing pluses and minuses, but since it equals 107, it’s not a solution.

I call this a “doodle problem”: one that’s best worked on during meetings where you might be doodling otherwise.

You might want to start looking for solutions that use a total of seven pluses and minuses (although there are ways to use fewer).

Riddle No. 17: This Math Puzzle Stumped Every Scientist but One. Think You Can Crack It?

Difficulty: hard.

In honor of Freeman Dyson, the renowned physicist who died last month , here’s a legendary tale demonstrating his quick wit and incredible brain power.

One day, in a gathering of top scientists, one of them wondered out loud whether there exists an integer that you could exactly double by moving its last digit to its front. For instance, 265 would satisfy this if 526 were its exact double—which it isn’t.

After apparently just five seconds , Dyson responded, “Of course there is, but the smallest such number has 18 digits.”

This left some of the smartest scientists in the world puzzling over how he could have figured this out so quickly.

So given Dyson’s hint, what is the smallest such number?

My second grader has recently learned how to add a 3-digit number to itself using the classic vertical method:

Font, Text, Calligraphy, Line, Art, Writing,

18-digit numbers, of course, can be added in the same way.

Riddle No. 18: Figure Out What’s on Her Forehead

Cecilia loves testing the logic of her very logical friends Jaya, Julian, and Levi, so she announces:

“I’ll write a positive number on each of your foreheads. None of the numbers are the same, and two of the numbers add up to the third.”

She scribbles the numbers on their heads, then turns to Jaya and asks her what her number is. Jaya sees Julian has 20 on his forehead, and Levi has 30 on his. She thinks for a moment and then says, “I don’t know what my number is.” Julian pipes in, “I also don’t know my number,” and then Levi exclaims, “Me neither!” Cecilia gleefully says, “I’ve finally stumped you guys!”

“Not so fast!” Jaya says. “Now I know my number!”

What is Jaya’s number?

Jaya could be one of two numbers, but only one of those numbers would lead to Julian and Levi both not knowing their numbers. Why?

Riddle No. 19: Can You Get Keanu Reeves Elected As President?

It’s 2024, and there are five candidates running in the democratic primary: Taylor Swift, Oprah Winfrey, Mark Cuban, Keanu Reeves, and Dwayne Johnson. (Hey, it could happen.) As usual, the first primary is in Iowa.

In an effort to overcome its embarrassment after the 2020 caucus debacle , the Iowa Democratic Party has just announced a new, foolproof way of finding the best candidate: there will be four consecutive elections.

First, candidate 1 will run against candidate 2. Next, the winner of that will run against candidate 3, then that winner will run against candidate 4, and finally the winner of that election will run against the final candidate. By the transitive property, the winner of this last election must be the best candidate ... so says the Iowa Democratic Party.

Candidate Keanu has been feeling pretty low, as he knows he is ranked near the bottom by most voters, and at the top by none. In fact, he knows the Iowa population is divided into five equal groups, and that their preferences are as follows:

Text, Font, Line, Organism, Document, Number, Handwriting, Calligraphy, Smile, Art,

Keanu is childhood friends with Bill S. Preston, Esq., the new head of the Iowa Democratic Party. Preston, confident that the order of the candidates doesn’t matter for the outcome, tells Keanu he can choose the voting order of the candidates.

So what order should Keanu choose?

Riddle No. 20: Who Opened All These Damn Lockers?

There are 100 lockers that line the main hallway of Chelm High School. Every night, the school principal makes sure all the lockers are closed so that there will be an orderly start to the next day. One day, 100 mischievous students decide that they will play a prank.

The students all meet before school starts and line up. The first student then walks down the hallway, and opens every locker. The next student follows by closing every other locker (starting at the second locker). Student 3 then goes to every third locker (starting with the third) and opens it if it’s closed, and closes it if it’s open. Student 4 follows by opening every fourth locker if it’s closed and closing it if it’s open. This goes on and on until Student 100 finally goes to the hundredth locker. When the principal arrives later in the morning, which lockers does she find open?

Make sure you pay attention to all of the factors.

3. If I am holding a bee, what do I have in my eye?

4. An old man dies, leaving behind two sons. In his will, he orders his sons to race with their horses, and the one with the slower horse will receive his inheritance. The two sons race, but since they're both holding their horses back, they go to a wise man and ask him what they should do. After that, the brothers race again — this time at full speed. What did the wise man tell them?

short problem solving riddles

Answer: To switch horses.

Explanation:  After they switch horses, whoever wins the race will get the inheritance because they still technically own the losing (i.e., slower) horse.

5. Turn me on my side and I am everything. Cut me in half and I am nothing. What am I?

6. A farmer needs to take a fox, a chicken, and a sack of grain across a river. The only way across the river is by a small boat, which can only hold the farmer and one of the three items. Left unsupervised, the chicken will eat the grain, and the fox will eat the chicken. However, the fox won't try to eat the grain, and neither the fox nor the chicken will wander off. How does the farmer get everything across the river?

short problem solving riddles

Answer: The farmer must follow these steps.

1. Take the chicken across the river. 2. Come back with an empty boat. 3. Take the grain across the river. 4. Bring the chicken back. 5. Take the fox across the river. 6. Come back with an empty boat. 7. Take the chicken across the river.

7. If you have a 7-minute hourglass and an 11-minute hourglass, how can you boil an egg in exactly 15 minutes?

short problem solving riddles

Answer: To boil the egg in exactly 15 minutes, follow these steps.

1. Start both hourglasses as you start boiling the egg. 2. After the 7-minute hourglass runs out, turn it to start it again. 3. Four minutes later, when the 11-minute hourglass runs out, turn the 7-minute hourglass again. 4. Wait for the 7-minute hourglass to run out, which will take another four minutes and get you to exactly 15 minutes of boiling time.

8. You are walking down a road and come to a fork. One path leads to certain death; the other leads to eternal happiness. You don't know which is which. In the middle of the fork, you come across two brothers who know which road is which. One brother always tells the truth and the other always lies. You can only ask them one question. How would you determine which road to take?

short problem solving riddles

Answer: Ask each brother, "If you were your brother, which road would you say leads to eternal happiness?"

Explanation:  Let's say the path on the right leads to eternal happiness. After you ask your question, both brothers will tell you the exact same thing: "He would say the left path leads to eternal happiness."

As Reddit user OnscreenForecaster explained, "In either case ... you would pick the opposite of what they both say because one is telling the truth about it being a lie, and one is lying about it being the truth."

Source:  SneeKeeFahk, Reddit

9. What is next in this sequence of numbers: 1, 11, 21, 1211, 111221, 312211, ______?

short problem solving riddles

Answer: 13112221.

Explanation:  Each sequence of numbers is a verbal representation of the sequence before it. Thus, starting with 1, the next sequence would be "one one," or "11." That sequence is followed by "two one," or "21," and so on and so forth.

Still confused? Here's a good explanation by Reddit user hankthetank921 :

The first number is just ONE (amount) "1" (0-9 numeral). So if you say there's ONE "1" (seriously just say it aloud) the next number would be an 11. Then there are TWO "1's", creating 21. Then ONE "2" and ONE "1" which creates 1,211. Then ONE "1", ONE "2", and TWO "1's" creating 111,221 ... and so on.

10. Four people arrive at a river with a narrow bridge that can only hold two people at a time. It's nighttime and they have one torch that has to be used when crossing the bridge. Person A can cross the bridge in one minute, B in two minutes, C in five minutes, and D in eight minutes. When two people cross the bridge together, they must move at the slower person's pace. Can they all get across the bridge in 15 minutes or less?

short problem solving riddles

Answer: Yes, they can cross in exactly 15 minutes.

Explanation:  The group of four must follow these steps.

1. First, A and B cross the bridge and A brings the light back. This takes 3 minutes. 2. Next, C and D cross and B brings the light back. This takes another 10 minutes. 3. Finally, A and B cross again. This takes another 2 minutes.

11. A rebus is a pictogram that represents a word, phrase, or saying. For example, "Ci ii" represents "See eye to eye." What word or phrase does the following rebus represent: O_ER_T_O_?

short problem solving riddles

Answer: Painless operation.

Explanation :  The letters missing in O_ER _T _O_ (OPERATION) spell out PAIN. Thus, "pain-less" operation.

Source:  kjivxx, Reddit

12. During a recent census, a man told the census taker that he had three children. When asked their ages, he replied, "The product of their ages is 72. The sum of their ages is the same as my house number." The census taker ran to the man's front door and looked at the house number. "I still can't tell," she complained. The man replied, "Oh that's right, I forgot to tell you that the oldest one likes chocolate pudding." The census taker then promptly wrote down the ages of the three children. How old are they?

short problem solving riddles

Answer: 3, 3, and 8.

Explanation:  As Reddit users  TT1103 and RedditRage explained, the key to this brain teaser is that the census taker looks at the house number. In other words, she knows the sum of the children's ages.

However, at that point of the riddle, she still can't tell how old the man's children are. Therefore, she has to be stuck between multiple possibilities. To narrow it down further, only two sets of numbers that multiply to 72 share the same sum: (2,6,6) and (3,3,8).

After the man reveals that his oldest   child likes chocolate pudding, however, the census taker can differentiate between the two options. That is, only the latter of those two sets has a distinct "oldest" child.

13. You're in a dark room with a candle, a wood stove, and a gas lamp. You only have one match, so what do you light first?

short problem solving riddles

Answer: The match.

Source: notarobot45, Reddit

14. There are five bags of gold that all look identical, and each has 10 gold pieces in it. One of the five bags has fake gold in it. The real gold, fake gold, and all five bags are identical in every way, except the pieces of fake gold each weigh 1.1 grams, and the real gold pieces each weigh 1 gram. You have a perfectly accurate digital gram scale and can use it only once. How do you determine which bag has the fake gold?

short problem solving riddles

Answer: Take one gold piece from the first bag, two from the second bag, three from the third bag, four from the fourth bag, and five from the fifth bag. If the weight on the scale ends in .1, then you know the first bag has the fake gold. If the weight on the scale ends in .2, then the second bag has the fake gold, and so on and so forth.

30 Math Riddles (With Answers)

short problem solving riddles

Math may not be everyone’s cup of tea, but when you think about it, it’s everywhere. Most of us likely do some type of math just about every day. So how can we make learning math and improving our problem-solving abilities more enjoyable? The answer is easy—riddles! And these math riddles are a great place to start.

These riddles span various age levels and abilities. Try some out yourself or gather the kids and make it a family or school activity. Math is fundamental, so there’s no time like the present to fine-tune those skills!

Calling All Math Masters!

If you enjoy math riddles, you’re bound to love the Math Masters category of our in-home scavenger hunts ! All you’ll need is your family, your internet-enabled device, and your competitive spirit. Our intuitive interface will have you connected, solving clues, and completing challenges in no time.

Developed in conjunction with 2 elementary school teachers, this hunt makes problem-solving a blast! When you’re done with that category, there are several more from which you can choose. The one thing they all have in common is FUN!

1. Riddle: A merchant can place 8 large boxes or 10 small boxes into each carton for shipping. In one shipment, he sent a total of 96 boxes. If there are more large boxes than small boxes, how many cartons did he ship? Answer: 11 cartons total: 7 cartons of large boxes (7 * 8 = 56 boxes), 4 cartons of small boxes (4 * 10 = 40 boxes).

2. Riddle: I have a calculator that can display ten digits. How many different ten-digit numbers can I type using just the 0-9 keys once each, and moving from one keypress to the next using the knight’s move in chess? (In chess, the knight move in an L-shape—one square up and two across, two squares down and one across, two squares up and one across, and other like combinations.) Answer: You can form the numbers 5034927618 and 5038167294. You can also form their reverses: 8167294305 and 4927618305. Hence four different numbers can be made.

3. Riddle: When my dad was 31, I was just 8 years old. Now his age is twice as old as my age. What is my present age? Answer: When you calculate the difference between the ages, you can see that it is 23 years. So you must be 23 years old now.

4. Riddle: An insurance salesman walks up to a house and knocks on the door. A woman answers, and he asks her how many children she has and how old they are. She says I will give you a hint. If you multiply the 3 children’s ages, you get 36. He says this is not enough information. So she gives a him 2nd hint. If you add up the children’s ages, the sum is the number on the house next door. He goes next door and looks at the house number (13) and says this is still not enough information. So she says she’ll give him one last hint which is that her oldest of the 3 plays piano. Why would he need to go back to get the last hint after seeing the number on the house next door? Answer: After the first hint, there are several different options. When he realizes the sum is 13, the answer is one of two possibilities. The third hint indicates there is an “oldest” daughter. Since one of the two options includes older twins (1 + 6 + 6 = 13) and the other includes young twins (2 + 2 + 9 = 13), the daughters must be 2, 2, and 9.

5. Riddle: Scott has $28.75. He purchased three cookies that cost $1.50 each, five newspapers that each cost $0.50, five flowers for $1.25 each, and used the remainder of the cash on a pair of sunglasses. How much were the sunglasses? Answer: $15.50.

6. Riddle: What is the smallest whole number that is equal to seven times the sum of its digits? Answer: 21. The two-digit number ab stands for 10a + b since the first digit represents 10s and the second represents units. If 10a + b = 7(a + b), then 10a + b = 7a + 7b, and so 3a = 6b, or, more simply, a = 2b. That is, the second digit must be twice the first. The smallest possible number is 21.

7. Riddle: A monkey is trying to climb a coconut tree. He takes 3 steps forward and slips back 2 steps downward. Each forward step is 30 cm and each backward step is 40 cm. How many steps are required to climb a 100 cm tree? Answer: 50 steps.

8. Riddle: In a mythical land 1/2 of 5 = 3. If the same proportion holds, what is the value of 1/3 of 10? Answer: 4.

9. Riddle: It is 9 am now. Rita studies for 2 hours, takes a bath for 1 hour, and then has lunch for 1 hour. How many hours are left before 9 am tomorrow? Answer: 20 hours.

10. Riddle: There is an empty basket that is one foot in diameter. What is the total number of eggs that you can put in this empty basket? Answer: Only one egg! Once you put an egg into the basket, it’s no longer an empty basket!

Need a break from all that math? Our list of funny riddles is giggle-worthy!

12. Riddle: If you multiply this number by any other number, the answer will always be the same. What is the number? Answer: Zero.

13. Riddle: A grandfather, two fathers, and two sons went to a movie theater together and everyone bought one movie ticket each. Movie tickets cost $7.00 and their total was $21.00. How? Answer: They purchased 3 tickets. The grandfather is also a father and the father is also a son.

If I deal to five people, two cards remain. How many cards are there? Answer: There are 47 cards. A complete deck is 52 cards. 5 cards have been lost.

15. Riddle: Tom was on the way to the park. He met a man with seven wives and each of them came with seven sacks. All these sacks contain seven cats and each of these seven cats had seven kittens. So in total, how many were going to the park? Answer: 1. Only Tom was going to the park.

16. Riddle: I am an odd number; take away a letter and I become even. What number am I? Answer: Seven. (SEVEN-S=EVEN.)

17. Riddle: How can you add eight 8’s to get the number 1,000? Answer: 888 + 88 + 8 + 8 + 8 = 1,000.

18. Riddle: If there are four apples and you take away three, how many do you have? Answer: Three apples.

25. Riddle: A carton contains apples that were divided into two equal parts and sold to two traders Tarun and Tanmay. Tarun had two fruit shops and decided to sell an equal number of apples in both shops, A and B respectively. A mother visited shop A and bought all the apples in the shop for her kids. But one apple was left after dividing all the apples among her children. If each child got one apple, what is the minimum number of apples in the carton? Answer: 12. That is the minimum possible number of apples for each child to have at least one.

26. Riddle: A duck was given $9, a spider was given $36, and a bee was given $27. Based on this information, how much money would be given to a cat? Answer: $18 ($4.50 per leg).

27. Riddle: The speed of a train is 3 meters/second and it takes 10 seconds to cross a lamp post. What is the length of the train? Answer: 30 meters. The time taken by the train to pass the stationary object is equal to the length of the train divided by the speed of the train.

28. Riddle: It takes 12 men 12 hours to construct a wall. Then how long will it take for 6 men to complete the same wall? Answer: It would probably take 24 hours, but there is no need to make it again. The job is already done!

And best of all, it gives you a chance to bond. Work on solving each riddle together as a fun family activity!

How to help your child create their own riddles

Once your child has completed our list of riddles, take their skills to the next level with homemade riddles! Encourage your child to create their own riddles using the following steps: 

1. Start with the answer

Come up with the solution to your riddle first, then work backwards to create your question. Your solution can be almost anything, but choosing a physical object is an easy way to start. 

Ex. The answer to my riddle is “carrot.”

2. Brainstorm

Write down any words or phrases that could be associated with your answer. 

  • Similar things
  • Things it does 
  • Features it has
  • How to describe it

Ex. Carrots are orange with green leaves on top. 

3. Think like your answer

If your answer were a person, what would they think? What would they do? How would they describe themselves? How would they see the world around them? 

Ex. If I were a carrot, I might think I was wearing a green hat.

4. Think outside the sentence

Use figurative language — like a metaphor, simile, personification or hyperbole — to make comparisons or describe your answer in new ways. This is often what makes the riddle tricky for the reader to solve. 

Ex. A carrot sounds like “a parrot.” 

5. Write your riddle!

Now that you have the backbone of your riddle, the only thing left to do is write! Use clear, descriptive language to write out your riddle, then share it with friends and family to see if they can solve it. 

If you want to show your riddle in a different way, you could even think about presenting it as a pun, like a knock-knock joke! Or if you’re looking to make a really tricky riddle or a brain teaser, you could use something visual like a deck of cards.

Ex. I’m orange, wear a green hat and sound like a parrot. What am I?
