A brain teaser quiz that requires outside-the-box thinking
When you think of riddles and witty solutions, some of you might picture Ikkyu-san.
There was even an animated TV show about him, right? Faced with tricky problems—like a sign by a bridge over a river that says, “Do not cross this bridge”—Ikkyu-san would solve them with clever wit.
This wit, which is practically synonymous with Ikkyu-san, is said to mean wisdom that comes to you on the spot, suited to the situation.
The quiz we’re introducing this time will also require some smarts.
Read each question carefully and think from different angles.
You might solve it by rearranging letters, or it could involve two words with the same meaning.
Use the right kind of wisdom for each question and work your way through them.
A trick quiz that’s trending on social media
“Trick questions” have been around for a long time, but thanks to the evolution and growth of social media, they’re now easier to enjoy than ever.
One of the fun things about these quizzes is that even if you jump to conclusions with an “Ah, I’ve got it!” and fall for the trick, it’s still entertaining.
For example: “You have 5 candies.
If you lick one, how many are left?” You might instinctively answer “4 left!” because 5−1=4, but the correct answer is 5.
That’s the hallmark of trick questions: they cleverly exploit our urge to answer faster than everyone else.
Sometimes it’s important to stay cool-headed!

A trick riddle that will definitely catch you 200%
It looks like an ordinary riddle where you find clues in the question and figure out the answer, but it actually needs one more twist.
Words that seem like hints in the question are meant to lead you to the wrong answer, so take a moment to think carefully.
Since the thing you arrive at quickly is likely to be wrong, it’s a good idea to consider answers that are not that.
Vividly imagining the characters that appear in the problem might also be an important key to reaching the correct answer.
