Classic Board and Card Games (21–30)
Nine Tiles

Nine Tiles is a fast-paced game where you slide and flip the nine tiles in front of you to match the arrangement shown on the challenge card.
It’s only nine tiles, but just figuring out the placement and orientation gets your brain and hands working at full throttle! Your concentration and decision-making are put to the test as you race to finish before anyone else.
Because rounds are quick, you can play again and again, making it fun for both kids and adults—and it’s easy to get everyone excited.
You’ll be using your head while keeping your hands busy, so it’s a game you can’t help but get absorbed in.
The rules are simple, yet the sense of accomplishment will have you coming back for more.
Give it a try!
Board game ‘Cloak’

This is a game where you rearrange pieces of various colors to line up three of the same color before your opponent.
It’s not just about moving pieces—each player also has lids to cover the pieces, so you have to remember which color is inside as you play.
Even if you place a piece yourself, you still need to remember it, so it really tests advanced strategy and memory.
There are even situations where you declare a match but it turns out not to be correct due to a memory slip, and that kind of bluffing and mind game is part of the fun.
The board game “For Sale” (Hagetaka no Eji)}

It’s a game where you enjoy the mind games of choosing which score to go after and with what number: if you play a number from your hand that’s higher than everyone else’s, you claim the points currently on the table.
However, some of the score cards that appear on the table are negative, so you avoid those by playing low numbers—this push-and-pull makes the bluffing even more intense.
It’s also crucial that your hand size is limited and that if played cards tie, no one gets the points.
Keep an eye on what remains in both your hand and your opponent’s as you steer the game to your advantage.
Wordplay & Quiz Game (1–10)
Mansion Game

Let me introduce a rhythm-based apartment game.
There is a five-story apartment building, and the person who first reaches the 5th floor loses.
Assign room numbers to players one by one.
For example, rooms on the first floor are numbered 101, 102, 103, and so on.
Once the game starts, say your own room number, then call out the room number of the next person.
Keep the game moving at a steady tempo with hand claps and a time limit.
If someone is called but fails to respond in time, their room number advances to the next floor—201, 202, 203, etc.
The person who ends up reaching the 5th floor loses.
It’s a thrilling apartment game—let’s keep our focus and play with good rhythm.
Antonym Game

It’s a game where, to the rhythm, you answer with the antonym of the previous person’s word.
An antonym means an opposite word—“small” is a good example as the antonym of “big.” Players sit in a circle, choose a starting person, and go clockwise.
The fun twist is that it’s okay to say a word that doesn’t have a true antonym.
For example, if someone says “apple,” you can answer “banana”—as long as the group accepts it as an antonym, anything goes! Don’t overthink it; just say whatever comes to mind and have fun.
An interview where you must not say “yes”

In everyday life, we often say “hai” as a response when someone speaks to us.
This is a game where you’re not allowed to say that “hai”! With seniors or superiors, we tend to be mindful of polite language and end up saying “hai” automatically.
You could try playing with a senior at work, but it’s especially fun to play in the format of a job interview—a situation where the word “hai” comes out most easily—even among friends who don’t usually use polite speech.
The person acting as the interviewer asks questions, and the interviewee is forbidden from saying “hai.” Each time they’re asked something, how well can they stop themselves from unconsciously blurting out “hai”? Can they rephrase it with different words? Surprisingly, this is quite difficult!
A game where everyone matches their answers

This is a game where each person thinks of an answer to a question, and the goal is for the team to match their answers.
With broad prompts like “What comes to mind when you think of a beautiful flower?” or “What comes to mind when you think of a pet?”, you can also get a glimpse into how everyone thinks.
You can enjoy it with various rules, such as earning points if your team matches, or giving points to those who match when everyone answers at once.
It also seems like it would be exciting to have members discuss without saying the exact answer, aiming to compromise and come together.
Atama-Oshiri Game

It’s a game where you’re given the first and last letters, and you fill in the letters in between to make a single word.
The twist is a 10-second time limit.
With the deadline closing in… doesn’t just imagining it make you a little nervous? You might draw a blank on answers that you’d normally think of right away.
It’s perfect for lively, friendly fun with everyone chatting and laughing together.
If someone comes up with a long word, it’s sure to make the room even more excited.
High-Energy Prince Shōtoku Game

As we become adults, we tend to compliment our friends face-to-face less often.
For people like you, I recommend the “Age-Age Prince Shōtoku Game.” In this game, you role-play as Prince Shōtoku, who is said in legend to have been able to listen to ten people at once, and you try to distinguish multiple compliments being said simultaneously.
Because you have to seriously listen to people praising you, it’s a slightly embarrassing, blush-inducing game.
Majority Game

As we go about our days without much thought, we tend to assume our ideas and actions are shared by most people, and we may not even realize that we’re actually in the minority.
This game lets you see where everyone stands, and it also works as a check to see whether your opinion is in the majority or the minority.
You pose a two-choice question that you believe most people will agree with, everyone answers at once, and those in the minority receive a penalty.
The stronger someone’s preconceived notions are, the greater the shock may be when they find out they’re actually in the minority.
