Wordplay & Quiz Games (11–20)
Oogiri Guessing Quiz

Even as adults, many of our friends are people we know inside and out.
You can probably even guess the kind of answers they’d give in an improv-style comedy prompt.
In this game, you try to match each witty answer to the friend who wrote it.
It could be fun to award points for correctly guessing who wrote which answer.
Number guessing game

This “number-guessing game” is simple yet surprisingly deep.
First, players form a circle.
One person calls out a number, and everyone chooses to either sit or stand accordingly.
If the called number matches the number of people who are standing, that person wins.
There’s a psychological element to it, so it’s sure to excite adults as well.
You can also tweak it so that matching the number means you lose.
Try adjusting the rules to suit the number of players and the group’s dynamics.
No Voiced-Sound Game

Voiced sounds refer to “muddy” sounds like da and ji.
For example, daijoubu and gomen are words that contain voiced sounds.
This game is about having a conversation while banning these voiced sounds.
When you talk, choose a topic and discuss it.
Saying you won’t talk is not allowed.
Remove the voiced sounds and keep the conversation going.
If you answer reflexively, you’ll end up speaking as usual, so be careful.
Announcing that there will be a penalty game for each voiced sound used will make it more thrilling!
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!

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.
