Riddle Trick Quiz
Trick questions are hard to solve precisely because you can’t answer them with just knowledge or common sense.
But that’s what makes them a fun brain workout and great for getting everyone excited! So this time, we’re introducing some “trick riddle quizzes.” Some of these are a bit mean-spirited, with answers that make you go, “Wait, that counts?” so be careful.
Even if you’re sure you’ve found the right answer, try looking at it from another angle.
The answer you’re certain can’t be right might actually be the correct one.
If you didn’t get caught, you’re a genius.
Let me introduce a “Gotcha-Free Genius Quiz” that also serves as brain training for kids.
The questions are simple, but the answers are a bit twisty.
Try to think about what kind of quiz it is while you work out the answers.
You might find that answering by intuition helps you come up with the answers more quickly.
The more you try not to get tripped up, the more you might fall for the traps, right? Stay relaxed and answer with your intuition.
Make it a fun quiz game that trains your brain!
Ultra-difficult trick quiz
Are you bad at trick questions? I couldn’t even get the classic one—“Which is heavier, 1 kg of iron or 1 kg of cotton?”—I just kept groaning and never reached the right answer.
I’m the type who overthinks and self-destructs, assuming there must be some hidden twist just because it’s presented as a question.
I can’t handle normal trick questions, so if they’re labeled “super hard,” then… As for those tougher trick questions, the rising YouTuber Chonmage Kozou—who suddenly appeared with the greeting “Hikiniku desu!”—is enjoying them too.
Elementary schoolers who don’t have much time, give them a try!
A cipher quiz using mathematical formulas
A cryptic quiz that looks like simple addition but uses completely different logic to reach the answer.
Equations that seem nonsensical—like 3+7=“trauma” or 4+6+2=“sea slug”—hide tricks such as the ordering of letters or words.
It’s recommended to consider the problem from multiple angles, including letter order and wordplay.
Finding the answer tests your ability to think outside the box.
It’s not just about logical reasoning; a feel for language is also required, making it a quiz that gets your whole brain firing—and becomes addictive.
What is the name of the old man who appears in Urashima Taro?

Speaking of Urashima Taro, it’s known as the story where he rides a turtle to the Dragon Palace, spends what feels like only a short time there, and when he returns, many years have passed in the world he came from and not a single acquaintance remains.
It’s a beautiful yet sorrowful tale, and surely everyone, from children to adults, has read it at least once.
Now, recall the story carefully and try this challenge.
If you’re thinking, “Did Urashima Taro have a grandfather?” you won’t reach the right answer.
The hint is to remember what happened to Urashima Taro when he opened the tamatebako (jeweled box)!
