A quiz where you fill in the blanks with the same hiragana character

When you want to train your creativity, how about trying a quiz where you fill the blanks with the same hiragana character? For example, you might see something like “〇しやき〇も,” and you put the same character in both blanks.
ところで、これは正解が「い」で、「いしやきいも」(ishiyaki-imo、stone-baked sweet potato)になります。
It can be fun to compete with friends to see who solves it faster.
And if you want to raise the difficulty a bit, quizzes where you fit in kanji are also recommended.
Since kanji often have multiple readings, these puzzles can be more complex.
Lettering Quiz

It’s a quiz where one part of a word is hidden and you have to fill in the same letter.
The words that come up are all simple.
It tests your vocabulary and your flash of insight.
The difficulty is somewhere between low and medium.
It’s easy to enjoy casually, so it’s recommended for breaks.
You could also try competing with your child—kids might surprisingly be better at it.
Type diagnosis with brain teasers

The more you use your brain, the more you can train it.
So let’s give it a solid workout with quizzes like these.
By determining your brain type, you can also figure out what kinds of questions you’re best at.
They’re great mental exercises, so try doing them before work or study to boost your concentration.
You might even awaken a variety of abilities.
Who am I? quiz

Brain training is great for improving memory and reasoning skills.
In particular, “Who am I?” quizzes are a fun way to get your thinking in high gear.
You infer the target object or person from various clues.
For example, a question might be posed like, “I like cold places and help you sweat.” The appeal lies in narrowing down the answer step by step while tackling tricky questions.
It’s fun to take turns making questions with family and friends, and answering quizzes on your own is also a good mental workout.
Why not use small pockets of time each day to keep your brain in top condition?
