Which two coins add up to 30 cents? & Other Mysteries Disclosed

Riddles are mind games meant to deceive and trick you. Some of us enjoy taking on challenges, while others easily become frustrated. But knowing the different types of riddles and how they are constructed will improve your ability to decipher these linguistic conundrums. which might turn out to be a really practical talent!

You’ll probably need to know how to solve puzzles if you ever find yourself in a situation where you’re trying to navigate a labyrinth but are stopped by a sphinx; otherwise, you won’t survive. Maybe you just want to keep your brain in shape and want to learn more about riddles. In any case, we’ll look at how to identify various types of riddles and assist you in solving them in this post.

How to Identify the Various Types of Riddles

Riddles can be classified as either enigmas or conundrums. Conundrums emphasise wordplay, while enigmas are creative puzzles. Let’s examine the differences between these two categories of riddles.


Enigmas are original queries, sentences, or claims. They typically contain word associations, metaphors, or allegories that make them challenging to solve.

illustrative of enigmas

Which came first, the chicken or the egg? is a conundrum. utilise logic and inventiveness. It might be regarded as a conundrum that has no answer (some scientists would argue that amniotic eggs evolved much earlier than chickens, though we think they might be missing the point).

“What can be swallowed, or can swallow a person?” is a clever conundrum puzzle. Twice, the term “swallow” is used, each time with a different, figurative intent. Pride is the solution to the puzzle.


Conundrums are a particular kind of riddle that frequently contains puns in the solution, the riddle, or both.

Examples of Puzzles

Two fathers and their two boys ate breakfast of eggs together. Each of them consumed one of the three eggs. Describe how. In this instance, one of the fathers is also one of one of the sons’ grandfathers.

Conundrum riddles frequently use the following format: “What is black and white and read all over?” It may seem more obvious when the solution is stated explicitly (it’s a newspaper). However, this puzzle depends on the similar sounding wordplay of red and read. Our minds are designed to hear “red all throughout,” especially considering that two of the hints are phrases that describe colours. Conundrum riddles, on the other hand, frequently demand that we take into account a word’s various meanings.

Solutions to Riddles

The janitor from the television series “Scrubs” spent time in the library researching coin history in order to solve the common conundrum, “What two coins create 30 cents and one of them is not a nickel?” He finally decided on a penny and a valuable out-of-misuse coin worth 29 cents. The solution to the conundrum is concealed, though. Only one of the coins, according to J.D from “Scrubs,” is a nickel, thus the second coin must be one as well.

Here’s a basic lesson on how to answer riddles to get you started on navigating seemingly tough riddles.

  1. Disassemble the conundrum.

It is easier to comprehend the enigma when each piece is viewed as a distinct entity. For instance, there are three pieces to the question “What two coins create 30 cents and one of them is not a nickel?”

Two coins: In the United States, a dollar is made up of two quarters, two dimes, one nickel, and one penny. These are worth, successively, 25 cents, 10 cents, 5 cents, and 1 cent.

Makes 30 cents — According to American coin logic, the only coins that can make 30 cents are the quarter and the nickel.

The tough thing is that one of the coins is not a nickel. One of the coins, according to the puzzle, is not a nickel. The fact that one of the quarter and nickel coins is not a nickel makes sense. We now have the definitive response.

  1. Consider the riddle’s activities.

The central action of a riddle like “What turns everything around yet does not move?” is turning everything around. You’re probably going to start picturing the rotation and movement of objects as the answer to the puzzle, which should be something that flips everything upside down. To clarify your thinking, keep in mind that the object itself shouldn’t move. What could change the situation without actually moving? The response? a reflection

  1. Does the riddle contain any other pertinent information?

Without fingers, I point, without arms, I strike, and without feet, I rush, according to the riddle. We perceive motion when we ask, “What am I? “. The thing in question lacks fingers, arms, and feet, despite the fact that the riddle implies some type of human movement.

We can presume that the riddle is trying to get us to picture someone, but we can override that inclination. Instead, think about how your first reaction is probably wrong and how the thing is probably not alive, which limits the range of potential answers to the mystery. “Strike” is another piece of vital information that stands out. “When the clock strikes nine” is a common idiom that may come to mind.

Advice on Solving Riddles

There are a tonne of puzzles out there. Here are some suggestions about how to approach tackling them.

The majority of puzzles will try to confuse you.

Riddles can be used to make people laugh, especially if they lead you astray by using logical associations. For instance, you might at first wonder how you might eat an elephant after hearing the age-old African conundrum, “How do you eat an elephant?” The solution to this conundrum is actually rather simple and can be found right in front of you: you eat an elephant like you would any other food, one mouthful at a time.

Usually, something familiar is the answer.

Rarely do puzzles require additional investigation or study. The majority of puzzles believe that the solution is obvious. Finding out if someone knows what they already know is what makes it fun. Riddles may initially appear difficult, yet frequently the solution is something you already know.

Maintain an Open Mind

Because riddles frequently utilise words you are acquainted with yet explain things in a different way than you are used to, it is simple to give up on them. Our advice Be open-minded.

Riddles can be as straightforward as a habitual practise you engage in or appear to be hard due to the wordplay techniques they employ. For instance, the riddle “Forward I’m heavy; backward I’m not” calls for flexibility. Can you determine the solution? We’ve placed it at the end so you have time to consider it.

Perfect Practice = Perfect!

You need to keep practising, even reverse-engineering the answers to riddles you might already be familiar with, to solve them more quickly. You can practise on many puzzles that are available online and in movies.

Make it a habit to play word games like crosswords as well. Your capacity to solve problems and spot trends and patterns more readily are both enhanced by doing this.

The reply is: a tonne!
