Feel Refreshed When You Solve Them! 10 Riddles

Recommended for kids and adults! Here are 10 riddle ideas that will refresh you when you solve them.
Riddles are easier to crack when you loosen up your thinking and approach them flexibly, right? This time, let’s take on riddles that feel satisfying to solve.
For example, there’s a question like: “It’s gas, but what kind of gas comes out after using the toilet?” Hints are available, but each question has a 10-second time limit! Give them a try!
What bug is in the center of the world?
What insect is in the middle of the world? You might be tempted to wonder, “Where is the center of the world?” but this is a riddle you can solve with a flash of insight—no geography knowledge needed.
The key point is that “sekai” (world) is intentionally written in hiragana as せかい.
It could have been written in kanji, which makes this suspicious.
By the way, the correct answer is “a mosquito” (ka).
It’s that blood-sucking pest we all hate in summer.
Why? Because the middle letter of せかい (se-kai) is か (ka)!
Even though it was taken, everyone’s laughing. I wonder why.
I ended up fighting after my friend and I both tried to take it… It’s something every elementary schooler has probably experienced at least once.
Having something taken from you feels awful and makes you sad, right? So let’s try this puzzle.
Why is everyone smiling even though something was ‘taken’? The first thing to think about when solving this is the meaning of the word ‘taken’ (torareta).
It’s deliberately written in hiragana, so try converting it to kanji and imagining what situation it might describe.
The answer is: because it was a photograph.
No matter how many times you call it, it never answers—what is it?
If you call your dad or mom, your teacher or your friends, they all answer you, right? But in this world, there are things that won’t respond no matter how much you call them… What are they? The answer is something you all know well.
The key to solving this riddle is to focus on the hiragana word yondemo.
First, try converting it to kanji.
If you try different options like 呼んでも (even if you call) and 読んでも (even if you read), you’ll arrive at the answer.
By the way, the correct answer is “a book.”
An elevator that can hold ten people broke and fell. Yet no one was injured. Why is that?
See the answer
Because no one was riding (it)/Because nobody was on it.
If an elevator breaks and falls down, normally you’d expect serious injuries, but the key point here is that no one was inside at the time. It says it’s for ten people, but it doesn’t say anyone was riding it. In other words, no one was in the elevator, so no one was injured.
Daddy frog goes ribbit-ribbit-ribbit, Mommy frog goes ribbit-ribbit, so what sound does the baby frog make?
See the answer
I won’t cry.
Young frogs are still in the tadpole stage, so they can’t croak like adult frogs. That’s why the answer is “they don’t cry/make sounds.” Comparing them to the calls of their father and mother helps you notice the differences in development. Not only appearance but also whether they can make sounds is a point of growth.

What animal is bigger than a whale but smaller than a killifish?
See the answer
dolphin
To say that there’s no animal bigger than a whale and smaller than a killifish, we use a pun: we say “iruka” (which means dolphin) as a play on words with “inai” (there isn’t). The trick is to change the intonation when you say the comeback line, like “Sonna no iruka!” (which can sound like “Is that a dolphin?” or “Who would buy that?” depending on intonation). The correct answer is “iruka” (dolphin).
