Wordplay & Quiz Games (11–20)
Who am I? game

If you’re looking for a brain-teasing game, “Who Am I?” is a great choice.
In this game, the responder pretends to have become something, and by asking others questions like “Am I a living thing?” or “Can I be eaten?”, they try to figure out what they are.
It’s fun as is, but it gets even more exciting if you set a limit on the number of questions beforehand or add extra rules like allowing one lie per game.
Trivia Quiz

Everyone, do you like trivia? When you watch TV shows that share trivia, you can’t help wanting to tell someone the next day—you want people to hear your trivia knowledge, right? (lol) This trivia-collection quiz isn’t just any quiz; it helps build your own knowledge, so I recommend it.
From things that make you feel proud to know, to things you might think you could’ve lived without knowing, let’s turn them into a quiz and try answering together.
You can make a quiz out of the knowledge you already have, but these days there are also plenty of videos that compile trivia!
Difficult Kanji Quiz

I think there are many people who are good with kanji, but some are better at writing them while others are better at reading them.
Of course, there are also people who aren’t good at them (haha).
How about playing a game where you read difficult-to-read kanji? It could be a fun way to learn and might even become a skill you can proudly show off somewhere.
In particular, fish names—kanji with the “fish” radical—include lots of tricky characters, like the ones you see on teacups at sushi restaurants.
There are also tough kanji for flowers, animals, and more, so let’s have fun getting excited over all kinds of difficult kanji!
Wordplay & Quiz Games (21–30)
Tongue Twister Challenge

The tongue twister challenge is a recreational activity that everyone can enjoy together, no matter their age.
The key is to read the designated phrase quickly without stumbling over the words.
The facilitator should demonstrate first; if they deliberately slip up, it can help participants relax and ease their nerves.
Start by practicing slowly at first, and once everyone gets used to it, gradually increase the speed.
It can also be fun to play in teams and compete for the best time.
Association & Shiritori Game

The “Association Shiritori Game,” which combines word association and shiritori, is a very fun game that strengthens creativity and thinking skills.
The first player picks a theme and chooses either association or shiritori, then passes it to the next player.
The next player responds with either something associated with the theme or a word that connects via shiritori.
The key is that each player, when their turn comes, can instantly choose whether to go with association or shiritori on the spot.
Focus and quick thinking might be crucial.
It can get really lively with a large group.
Make a palindrome

Palindromes—didn’t you ever think them up and play with them as a kid? You still see them now and then on TV quiz shows, too.
But as adults, we don’t often play with or think about palindromes, do we? It’s a simple pastime you can do anywhere as long as you have paper and a pen, but it gives your brain a little workout.
From short phrases to ones that make you think, “This long? Really?”, jot down whatever comes to mind while considering the meaning.
It’s just a game, but it doubles as brain exercise, so it’s a win–win.
Let’s compete to see who can come up with the most delightful palindrome!
Infinite Shiritori
@hannariz.haru Only people with a really good memory can do this, lol.#HannariestranslationTranslation
♬ Original song – Hannaries – Hannaries
This is a game of shiritori—where you take the last character of a word and connect it to a new word—that adds a memory element.
Instead of just saying the next word, you also line up all the words that have been said so far and then add the next one.
As the turns progress, it gets harder because you have to recall the sequence of how you got to the current word.
If you keep the turns moving to a rhythm, the difficulty increases but the rhythm helps you remember, so that pattern is recommended.
Dosukoi Game
@chiguhagu_staff Dosukoi game ☝️#Dosukoi Game#Yubi-SumaPlay
♪ Original Song – A Day in the Life of a Mismatched Employee – A Day in the Life of a Mismatched Employee
A simple and exciting “Dosukoi Game.” Form a circle with a few people and start with one hand clenched.
When the host says, “Dosukoi + [syllable],” participants raise their thumbs and shout a word that begins with that syllable, adding “dosukoi” at the end.
Those who say a word first advance, and the last person remaining loses.
You can keep changing the starting syllable (a, i, u, e, o, etc.) and enjoy it endlessly, so it’s sure to liven up parties.
Since it uses no props and trains concentration and improvisation, it’s also great brain training.
Wasshoi Game
@kiki_holdings A quick game for spare moments. Wasshoi Game. It gets super hard as the character count increases.
♬ Original Song – kiki_holdings – kiki_holdings
In the “Wasshoi Game,” one person picks a kana from the Japanese syllabary and declares, “Wasshoi [kana]!” Everyone raises their pinky finger like in the finger-counting game “Yubi Suma,” and you count the total number of raised pinkies.
Players then think of a word whose length matches that number of letters and that ends with the chosen kana; whoever shouts it out first with “___ wasshoi!” advances.
For example, if the chosen kana is ‘sa’ and there are four pinkies raised, someone might say, “Arekusa wasshoi!” It’s a playful hand game that’s both funny and great brain training.
Two-letter shiritori

Would you like to try playing two-letter shiritori? In regular shiritori, you connect the last letter of the previous word to the first letter of your word regardless of length, and the person who uses a word that ends with “n” loses.
This version adds one more rule: you can only answer with two-letter words.
It’s perfect for when regular shiritori is too easy and boring.
If you want to make it even harder, try banning repeated words or keeping a steady rhythm while playing.
It’s a real test of your vocabulary!
