Train your brain! Carefully selected brain training and ability development quizzes for adults (11–20)
Brain training to increase IQ

If you’re looking for brain-training style problems, this one is recommended.
The rules are simple: like flash mental arithmetic, numbers are shown one at a time for a brief moment; you memorize them and then answer by giving them in the reverse order of the final display.
For example, if “1, 8, 5” is shown, answering “5, 8, 1” is correct.
It may seem easy, but your brain is actually memorizing briefly displayed numbers, retrieving them, and rearranging them, which makes it a good brain workout.
It’s a problem you can enjoy like a game.
Brain-training quiz to strengthen inspiration and imagination

This is a puzzle-like quiz where you look at the examples given in the problem, discover a specific rule, and use that rule to find the answer.
The fun part is taking your time to study the examples and think about the rule.
It’s satisfying when you solve the quiz using the rule you’ve found, but many problems aren’t so straightforward, and the high difficulty is also a hallmark.
I think people who have solved many quizzes are better at finding the rules and more likely to get the right answer, so I recommend challenging yourself with lots of quizzes!
What hiragana is it?

This is a quiz where you look at hiragana from various angles rather than as whole characters and try to figure out which hiragana it is.
Your ability to capture the straight and curved lines of the character from photos or videos shown from different angles, and to imagine the surrounding shapes, will be tested.
Until you get used to seeing hiragana as completely different shapes, it might feel like a difficult quiz.
If you present multiple hiragana at once and develop it into figuring out what word is being spelled, the difficulty increases and it gets even more exciting.
A puzzle quiz with riddles that adults find challenging

The ability to generate ideas is called creativity, and it’s a skill required in all kinds of professions.
The puzzle quiz we’re introducing today, which can be quite challenging for adults, really puts your creativity to the test.
As we get older, our thinking tends to become fixed, making flexible thinking more difficult.
With the right spark of insight, even children, who have less knowledge than adults, might be able to solve it.
Try brainstorming and thinking in ways that can lead to different answers.
It’s a quiz the whole family can enjoy.
Observational Skills Diagnostic Test

An observational skills test is one where you find the single odd one out among many identical letters or illustrations.
You’ve probably seen those puzzles on social media where you have to spot the single ぬ hidden among a bunch of め, right? You can do it with similar-looking hiragana or kanji, and even with emojis.
It’s not a brain-taxing problem—you’re simply searching for the odd one out—so its appeal may be that you can immerse yourself without thinking too hard.
It seems like the perfect quiz when you want a quick change of pace.
