If you can solve it, you’re a true genius! Advanced riddles
These are advanced riddles said to be solvable only by people who can think flexibly.
You’re tested on your ability to closely observe the question text and identify which words serve as hints, and to combine those hints skillfully with your own knowledge.
Many hints involve paraphrasing words in the prompt, so it may help to, for example, convert kanji to hiragana to make things clearer.
Another way to speed up your answers is to look for reverse-reading patterns—finding words in the question text that relate to what’s being asked.
Five people are playing hide-and-seek. Two have been found. How many are left?
See the answer
2 people
When five people are playing hide-and-seek and two are found, that means three still haven’t been found. But one of those three is the seeker, so only two are actually hiding. The seeker is the one who looks for others, not the one who gets found, so they’re not counted.
A slightly mischievous and difficult riddle
This is a fun collection of problems featuring uniquely unexpected answers.
Among them is a riddle about the three monkeys carved on a historic building.
It’s full of irresistible puzzles for lovers of wordplay.
What is something that won’t break no matter how much you try to break it?
Have you ever had the experience of dropping something and breaking it? As the saying goes, “Anything with form will eventually break,” and glass or pottery will most likely shatter if you drop it.
But there are things in this world that don’t break even when you split them! In fact, they aren’t objects.
If you’re an elementary school student, isn’t there something you split during class? With that hint, you’ve probably figured it out.
The answer is “division.”
What is a ball that’s square, even though it’s still a ball?
Speaking of balls, they’re one of the tools used in ball sports, right? When you picture a ball, most of you probably imagine a round sphere.
However, since the question in this quiz says “square,” we need to look for a square ball.
Let’s forget about balls used in sports for a moment and think of something square that includes the word “ball” (booru) in Japanese.
If you’re an elementary school student, you’ve probably seen it at home or used it for crafts.
The correct answer is “danbooru” (cardboard).
