Wordplay & Quiz Game (1–10)
Lyrics hijacking game

As we become adults, many of us find ourselves revisiting the music we listened to in our student days.
When you get together with friends from the same generation, I recommend trying this “Lyric Takeover Game.” In this game, you start singing a song, and whenever the lyrics line up with the same part of another song’s lyrics, you switch over and “take over” with that other song.
It’s especially fun with people your age, because lots of nostalgic tunes will pop up.
Word game where laughing is forbidden

It’s just a game where you say words one after another, but the fun part is that no matter what word is said, you absolutely must not laugh.
It’s strange how even words you would normally never laugh at can become funny the moment you tell yourself you’re not allowed to laugh.
Try getting creative—make the delivery funny, or say an unfunny word with a straight face.
But be careful: if you overthink it, you might end up laughing at your own words! Whoever laughs first loses.
Word Wolf Game

A psychological “Word Wolf” game! First, prepare one card for each player.
Write the same word on all the cards except one, and write a completely different word on that single remaining card.
Then everyone takes a card and talks about the word written on their card.
The goal is to figure out who has the card with the different word.
At first, even if your word is the odd one out, you won’t realize it.
But if, during the conversation, you suspect you might be the different one, deliberately join in and try to confuse the others! If you successfully mislead everyone and no one thinks you’re the odd one out, you win.
If the others correctly identify the person with the different word, that person loses.

Rhythm 4 Game

I bet a lot of people love the nostalgic games they played back in their school days.
One game I recommend is the “Rhythm 4 Game.” It originally became popular thanks to the TV show ‘Let’s Go to School!’ and many people probably remember playing it as students.
Just playing it brings back old memories, so it’s sure to liven things up.
Magical Banana

It’s a game that originated from a variety show, where players link words inspired by the previous person’s word in time with a rhythm.
The key is to speak in rhythm, and under the pressure of a time limit, your ability to calmly come up with words is put to the test.
It’s also fun to split into teams and compete to see how long you can keep the rally going; in that case, not only each person’s creativity matters, but also choosing words that make it easier for the next player to respond.
Since the game progresses using only words, another advantage is that you can start easily as long as you have enough people.
A game where whatever you say gets answered with “XX.”

A game where you just reply with a set phrase no matter what someone says—what’s fun about that? you might think.
It seems easy because you just keep replying with the same words in a snappy rhythm.
But the prompts you’re given include little traps—words that make you stumble.
For example, if you’re told, “No matter what you’re asked, reply with ‘furabonogamu’,” you feel like you could do it, right? But when you keep answering quickly and rhythmically, some part of you gets led astray by the phrase ‘furoba no gomu’ (bathroom rubber), and you trip up.
It’s a simple yet tricky and fun game.
Rotational Shiritori

Shiritori is a classic, casual game for killing time.
But it can drag on endlessly and get messy when you don’t know when to stop.
In contrast, this “Rotational Shiritori” ends neatly and is played for speed.
You set a fixed number of turns in advance, and the game must come back around to end exactly on the starting word.
In other words, you choose the number of words beforehand, and after one full round, the last word must end with the same character the first word started with.
For example, if the shiritori starts with “a,” the last character must also be “a.” It’s smooth at first, but toward the end you have to connect words while considering the remaining count and possible words—making it a great brain workout as well.
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!
