[For Elementary School Students] Cipher Quiz: Fun Puzzle Riddles (11–20)
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!
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.
Image quiz that tests your imagination
This is a picture quiz where you look at an image that says “If you can answer within the time limit, you might be a genius?” and answer what it represents.
It tests your flashes of insight and imagination, and each question has a time limit.
Can you figure out what the numbers or illustrations stand for? The questions seem easy enough for elementary school students, but they might actually be tricky for adults.
It could be fun to compete as a parent and child.
If it’s too hard, you can always pause the timer and try.
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.
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.

Matchstick puzzle: Move one stick to make 1.
See the answer
Move the rightmost matchstick to make “ONE.”
When you're told to “make a 1,” you’d naturally think you have to create the actual shape of the numeral “1,” right? But if you think about 1 in different ways—like “hitotsu,” “first,” “one”—your thoughts start to wander and then you go, “Aha!” That’s why it works. It’s a bit tricky for people who don’t know how to spell the English word ONE.
