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.
