Cipher Quiz

This is a video about finding answers hidden in what looks like incomprehensible ciphers at first glance.
With elementary school–level observation and creativity, the puzzles are easy to solve.
Some parts may not fit with an adult way of thinking, so it might be fun to try them out on yourself or your friends and play around with it.
Pattern Quiz

This is a quiz where you grasp the whole picture, find a pattern, and derive the answer from it.
Basically, it involves identifying patterns in sequences of numbers, testing not only creativity but also quick calculation skills.
It seems clear to first propose candidate patterns based on how adjacent numbers are related, then narrow them down by checking whether they apply to the next numbers as well.
Some items include multiple steps of calculation within a single number, so people who aren’t comfortable with numbers may find it even more difficult.
9 Apple Job Interview Questions

There are times when entrance exam questions from global IT companies are presented as quizzes, right? These kinds of questions often require logical thinking, and they’re also said to be difficult because they may demand various other types of knowledge and a mathematical sense.
So this time, we’re introducing questions that were actually asked in Apple’s entrance exams.
They’re recommended for people who enjoy thinking logically and for those who like imagining different patterns and running simulations.
Caesar Cipher Quiz

This is a quiz that uses the Caesar cipher, which creates a code by shifting letters by a fixed number.
For example, if you shift “WORLD” forward by 3 letters, it becomes “ZRUOG.” Even if a word looks meaningless at first glance, the key point is that you can reveal the original word by shifting back using the same rule.
To decode it, you need careful observation and patience to determine the correct shift amount, but the sense of accomplishment when you grasp the pattern can be addictive.
It’s perfect as brain training for adults, since you can have fun while honing logical thinking.
Once you get used to it, you can also encrypt your favorite words yourself and exchange them with friends, making it a quiz with a wide range of ways to enjoy.
Cipher & Pattern Quiz

This is a cipher quiz where you find a pattern to arrive at the answer.
At first glance, it may look like a meaningless string of letters or formulas, but try replacing them with other letters, numbers, or words to uncover the pattern.
Once you do, the answer will come into view.
The pattern itself uses knowledge you’re all familiar with, so it’s not that difficult.
However, you will need a flash of insight, so keep an open mind as you think.
Start by testing any patterns that come to mind and look for a foothold.
A cipher riddle quiz using kanji

The combination of kanji and ciphers is a puzzle packed with brain-training elements that make the most of the depth of Japanese.
You’re given the reading of three kanji characters as a hint, and the challenge lies in how to use it.
It’s a riddle where you search for clues from a lined-up string of kanji.
Sometimes romaji serves as a hint, and answering while considering meanings tests your mental flexibility.
Simply knowing kanji isn’t enough—you need creativity and a shift in perspective, which is part of the appeal.
It’s a puzzle that lets you experience the fun of looking at kanji from an unusual angle.
