[For Elementary School Students] Cipher Quiz: Fun Puzzle Riddles (11–20)
Average-level crypto quiz

An average-level puzzle quiz that trains language skills and thinking ability.
Many of the questions are themed around kanji and numbers, making it perfect for situations where elementary school knowledge can be put to use.
If it’s hard to solve within the time limit, it’s fine to offer simple hints.
The key is to give hints that don’t get too close to the answer, like “Try converting it into kanji or hiragana!” Also, even problems that look easy can stump adults, so a parent-child showdown could be fun.
As you answer the quizzes, try tackling problems that double as brain training and study.
Illustration Addition Quiz

Two illustrations appear, and you add them together.
The answer is a number, but since the problem is presented with pictures, it might get a bit confusing.
Interpret the illustrations, solve the riddle, and derive the answer.
It’s a fairly tricky quiz: you can’t just answer right away—you have to decipher the images and then figure out the result.
If you’re good at puzzles, you might solve it smoothly…? Once you hear the answer, it makes perfect sense (lol).
It’s a brain-training quiz that works your mind while you think.
Mystery Cipher

A cryptogram quiz where you can enjoy authentic mystery-solving.
Your detective-like reasoning will be tested as you search for the culprit based on various testimonies and clues.
Instead of taking the problem statement at face value, look for the culprit’s name hidden in the message from every possible angle.
Sometimes adults can’t solve a puzzle, but children’s flexible thinking leads them to the answer.
If the puzzle is hard to crack, give small hints about the suspects bit by bit.
Prepare paper or a whiteboard and try finding the culprit together as a parent and child while discussing your ideas.
Analyze the problem statement! Lateral-thinking quiz

A brain teaser quiz that you can’t solve if you’re too rigid? These witty quizzes often hide the answer right in the question—if you read carefully, you can work it out.
And even if you can’t figure it out at all, hearing the answer usually makes you go, “Ahh, of course!” The more you think about these kinds of quizzes, the deeper you get stuck and the further you seem to drift from the right answer—probably because your thinking is too rigid (lol).
They’re great for a little mental workout, too.
Rule Cipher Quiz

It’s a “rule cipher quiz” where a problem follows a certain rule, and you have to figure out what that rule is and then answer what fits it.
People tend to split into two camps with rule-based quizzes: those who are good at them and those who aren’t.
Elementary school kids might actually find the answers more easily than adults because their thinking is more flexible.
When you hear the answers, they all make you go, “I see!”—but you don’t get it until someone tells you (lol).
The more you think about it, the harder it gets, but it’s perfect for brain training!
A detective’s everyday problems

A quiz themed around the kinds of problems a detective might solve in everyday life.
Many of the questions can be cracked with a flash of insight and flexible thinking, making them perfect for elementary school students who study regularly.
Try reaching the answers through various approaches—like flipping letters upside down or converting words into kanji.
Although many look difficult at first glance, you’ll find they’re surprisingly simple once the solution clicks.
It’s a quiz that works in many settings, from parent–child showdowns to challenges with classmates at school.
By tackling word problems and trying your hand at puzzles, you can strengthen your thinking skills.

Uncrackable!? 12 Cryptography Puzzles

Ciphers involve finding patterns in a problem and arriving at the answer; in this context, more complex rules are used.
You’ll combine various rules within a single puzzle—such as rearranging tables, paraphrasing words, and even considering the typeface in which the problem text is written—to unravel it.
The most important skill is the ability to notice what feels off in a problem, and from that intuition, search for the hidden rules.
To solve within the time limit, it may be crucial to rapidly test and apply different rules in your head—the speed of your ideas matters.
