How much will it cost?
Riddle No. 4: Try to Solve This Pickleball Puzzle

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.

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:
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.)
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?
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).
Ready for the solution? Click here to see if you’re right.
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:
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:
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?
How would Keanu fare in one-to-one races against each candidate?
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.

38 Hard Math Riddles (With Answers) For Future Geniuses
Stump the mathletes of the family with these extra-tricky math riddles and puzzles.
No one’s indifferent to the long-form math word problem with the opening lines, “There are 67 people on a train traveling west at 45 miles an hour.” Those verbal equations tend to either thrill us or fill us with dread.

Albert Einstein’s 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 solve this brain teaser is through logic and deductive reasoning.
Think you can solve it?
Riddle: Five houses painted five different colors stand in a row. One person of a different nationality lives in each house. The five homeowners all drink some type of beverage, smoke a certain cigar brand, and have a certain kind of pet. But none of the owners drink the same beverage, smoke the same type of cigar, or have the same pet.
Here are the clues:
The Brit lives in the red house.
The swede keeps dogs as pets., the dane drinks tea., the green house is on the immediate left of the white house., the green house’s owner drinks coffee., the owner who smokes pall mall rears birds., the owner of the yellow house smokes dunhill., the owner living in the center house drinks milk., the norwegian lives in the first house., the owner who smokes blends lives next to the one who keeps cats., the owner who keeps the horse lives next to the one who smokes dunhill., the owner who smokes bluemasters drinks beer., the german smokes prince., the norwegian lives next to the blue house., the owner who smokes blends lives next to the one who drinks water.
Now, the question is, who owns the fish?
Answer: Five houses painted five different colors stand in a row. One person of a different nationality lives in each house. The five homeowners all drink some type of beverage, smoke a certain cigar brand, and have a certain kind of pet. But none of the owners drink the same beverage, smoke the same type of cigar, or have the same pet. So, in the end, the correct answer is that the German in house #4 owns the fish.
BONUS: A Fun Riddle Game
This riddle wordplay game is known as the Green Glass Door. It can be played at parties, in classrooms, and just as a fun icebreaker. If you’re a teacher looking to challenge your kids in the classroom, try out this entertaining logic puzzle to test their knowledge about compound words. (You know, those combined words, like sunflower [sun and flower] or moonlight [moon and light] or railroad [rail and road]). You’ll be sure to stump but also entertain your students with this tricky, yet funny riddle game.
Game Rules:
- Tell the group that you are going to take something through a Green Glass Door and that everyone else must also do the same in turn. The purpose of the game is to determine what can be brought through the Green Glass Door.
- Go first and say the following, “I can bring a kitten through the Green Glass Door but I cannot bring a cat.” This is because the rule is that the object brought through the Door must have double letters like the two “t”s in “kitten”.
- If a player tries to take an object through the Green Glass Door that doesn’t have a double letter, say “You cannot take that through the Green Glass Door. You must take…” Also, if a player believes they know the pattern, the game leader should question them and have them give an example rather than state the answer.
Were those easy riddles?

The Benefits of Solving Riddles
Solving riddles is not only a fun and engaging activity but also offers numerous benefits for your brain. When you tackle a riddle, your brain is forced to think critically, analyze information, and apply problem-solving skills. This mental workout can help improve your cognitive abilities, memory, and overall brain health.
Engaging with riddles also stimulates creative thinking and enhances your ability to think outside the box. Riddles often require you to make connections between seemingly unrelated pieces of information, fostering creativity and expanding your mental flexibility.
Moreover, solving riddles can be a great way to challenge yourself and improve your problem-solving skills. As you encounter more complex riddles, you’ll develop strategies for breaking down problems into manageable parts and applying logical reasoning to find solutions.
How Riddles Can Improve Critical Thinking Skills
Riddles are excellent tools for developing critical thinking skills. When faced with a riddle, you must carefully analyze the information given, identify patterns or hidden clues, and apply logical reasoning to arrive at the correct answer.
One of the key aspects of critical thinking that riddles help improve is deductive reasoning. Riddles often present a set of clues or information that needs to be pieced together to form a logical conclusion. By engaging with riddles regularly, you can enhance your ability to make logical deductions and arrive at accurate conclusions based on the available information.
Riddles also encourage lateral thinking, which is the ability to think creatively and approach problems from different angles. When solving a riddle, you may need to consider multiple possibilities, explore unconventional solutions, and think beyond the obvious.
Additionally, riddles promote problem-solving skills by challenging you to think critically and come up with creative solutions. The process of solving a riddle involves breaking down complex problems into smaller, more manageable parts and applying logical reasoning to find the solution.
The Psychology Behind Riddles and Brain Teasers
Riddles and brain teasers have fascinated humans for centuries, and their appeal goes beyond mere entertainment. The psychology behind riddles lies in the cognitive processes they engage and the mental challenges they present.
One of the reasons riddles are so engaging is because they tap into our innate desire to solve problems and find solutions. Humans have a natural inclination towards puzzles and challenges, and solving riddles satisfies this inherent need for problem-solving and intellectual stimulation.
Riddles also trigger a sense of curiosity and intrigue. The element of mystery and the promise of a solution entice us to engage with the riddle and invest our mental energy in finding the answer. This sense of curiosity keeps us engaged and motivated to solve the riddle, even when faced with difficulty.
Additionally, the element of surprise and the satisfaction that comes with solving a riddle releases dopamine in our brains. Dopamine is a neurotransmitter associated with pleasure and reward, and its release reinforces the positive feelings of accomplishment and satisfaction we experience when solving a challenging riddle.
Types of Riddles – Logic Puzzles, Lateral Thinking Riddles, and Math Riddles
Riddles come in various forms and categories, each with its unique set of challenges and problem-solving approaches. Let’s explore three common types of riddles:
Logic Puzzles
Logic puzzles are riddles that require you to apply deductive reasoning and logical thinking to arrive at the correct answer. These riddles often present a series of clues or statements that need to be analyzed and connected to solve the puzzle. Logic puzzles can involve various scenarios, such as crime scenes, mathematical problems, or spatial arrangements.
To solve a logic puzzle, you’ll need to carefully evaluate each clue, eliminate possibilities that contradict the given information, and make logical deductions to narrow down the options until you reach the correct solution.
Lateral Thinking Riddles
Lateral thinking riddles, also known as “thinking outside the box” riddles, require you to approach problems from unconventional angles and consider multiple possibilities. These riddles often involve wordplay, puns, or ambiguous language that can misdirect your thinking. To solve a lateral thinking riddle, you’ll need to challenge assumptions, explore different interpretations, and think creatively.
Lateral thinking riddles encourage you to break free from traditional thought patterns and explore alternative solutions that may not be immediately apparent. These riddles are designed to stretch your imagination and promote flexible thinking.
Math Riddles
Math riddles, as the name suggests, involve mathematical concepts and require you to apply numerical reasoning to find the solution. These riddles can cover a wide range of mathematical topics, including arithmetic, geometry, algebra, and logic.
To solve a math riddle, you’ll need to use your mathematical knowledge and problem-solving skills to analyze the given information and apply appropriate mathematical principles. Math riddles often require careful calculations, logical reasoning, and creative thinking to arrive at the correct answer.
Now that we’ve explored the different types of riddles, it’s time to put our problem-solving skills to the test with seven challenging riddles. Are you ready?

Enotria: the last song - all status effects, explained, enotria: the last song review, quick links, bargniff's first riddle answer in enotria: the last song, bargniff's second riddle answer in enotria: the last song, bargniff's third riddle answer in enotria: the last song.
Upon reaching the Clocktower while exploring Litumnia in Enotria: The Last Song , players will encounter a strange character called Bargniff . The fish-shaped NPC offers you to solve three riddles; in return, it will reveal the secrets of the Cosmos.
The Maskless One needs to meet Bargniff in three different locations since the moment you solve a riddle, the NPC will swim to another location. To unlock Litumnia, you must defeat Zanni in the first area and speak with Pulcinella to access the previously closed gate leading to the desired region. Here are the answers to all Bargniff riddles in Enotria: The Last Song and where to find Bargniff locations .
There are four status effects in Enotria: The Last Song and understanding the mechanic of each one will help immensely in battles.
Brains not brawn define you. You slice, you dice, but never flesh. Who are you?
The answer to the first riddle Bargniff gave is the Mask of Wits . Equip the Mask and speak with the fish to solve the riddle. Simply rest at the first Reality Knot to obtain Mask of Wits automatically .
Bargniff is located near the Clocktower Reality Knot, and it can be easily reached from the Old Docks Reality Knot. Once the riddle is solved, it moves to another location.
In ruby robes, you fervently implore, devotion unyielding, her voice you await. Who are you desperate one?
To solve the second Bargniff riddle in Enotria: The Last Song , you must defeat Vermiglio, the Red Prior boss in the Monastery of Maja . After that, equip the Vermiglio’s Mask and talk with the fish to solve the second riddle.
To find Bargniff’s second location, go to the Highborne Streets Waypoint and cross the bridge to climb narrow stairs. Ignore the grand staircase leading to an open door and instead run to the other side and go down another set of stairs. Keep going forward past enemies until you reach a gate. Drop onto the ledge to the side to reach Bargniff’s second location in Enotria: The Last Song .
Through winding waterways, your vessel glides, in a city of bridges, where secrets reside. Who are you?
The third Bargniff riddle is solved by wearing the Gondolier’s Mask in Enotria: The Last Song . Unlike the previous Mask where you get it through a boss fight, the Gondolier’s Mask is only obtained by farming the Gondolier enemies and collecting 100 Shards of their Masks .
You can find plenty of Gondolier enemies near the Old Docks Waypoint , although the number of Shards dropped depends on the characters’ Luck .
As for Bargniff’s third location in Enotria: The Last Song , reach the Mines of Gratia, which you can access by using the big elevator located underground. After unlocking the Mines of Gratia, jump down and head left. Ignore the enemies and defeat the Gondolier boss at the end of the path . The fish should appear right after you beat the boss .
