A cipher quiz using mathematical formulas

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.

Flash of inspiration riddle-solving quiz
This quiz is the type of brainteaser where, if you think you don’t know the answer, you could go on forever without finding it—but if you change your perspective or approach just a little, the answer pops into place as if by inspiration.
The moment it clicks, what you’ve been looking at appears completely different, so it’s also recommended for people who want to keep their minds flexible.
By regularly solving quizzes from various angles like this, you might make new discoveries in your daily life and end up living more enjoyably and conveniently.
Word Cipher Quiz
It’s a puzzle quiz that uses words and letters as ciphers.
The answers are hidden within words, revealed by changing orientation, or by combining many characters—making it a cipher quiz that seems to train reading comprehension.
All the letters can be a bit confusing at first, but if you think carefully, you’ll find the answers.
This quiz also works as brain training, and it could be exciting to style it like a TV quiz show where, once you figure out the answer, you submit it quietly and those who get it right drop out one by one.
Cryptic Cipher Quiz
It’s a quiz where speed of creativity matters: you’re given a cipher and must reach the answer within a time limit.
Each problem is drawn according to a certain rule, so the challenge is whether you can notice it or retrieve it from your knowledge.
Once the answer is revealed, it moves on to the next problem without much explanation, so it might be important to switch gears quickly instead of overthinking.
It’s recommended to review what rules were in play after everything is over.
Math quiz using pattern puzzles
This is a puzzle about patterns using hiragana and numbers.
Since it’s about patterns, you’ll need flexible thinking to come up with other possibilities.
Overthinking it makes it completely unreadable and quite a headache, but once you see the answers, you’ll be left slack-jawed in astonishment—these problems are full of moments like that.
