Classic Board and Card Games (1–10)
The Mind

The Mind is an analog game in which all conversation and communication are strictly forbidden.
Each player is dealt cards with numbers on them, and the goal is to play those numbers in ascending order.
If you think the number on your card is lower than everyone else’s, you play your card.
Until a card is played, you must not talk about it or make any kind of appeal or expression—no facial expressions or gestures.
If, by the time the last player has played, all the numbers are correctly arranged in ascending order, you succeed.
There are 12 level cards: at level 1 each player has 1 card; at level 10 each player has 10 cards.
As the level rises, it becomes increasingly difficult to judge which card should be played first and by whom.
Classic Board Games and Card Games (11–20)
Noi

Neu is a Japanese-born card game with simple rules that anyone can enjoy right away.
There are negative-number cards and positive-number cards, as well as special cards that reverse turn order, let you choose the next player, or double the total.
Players take turns playing cards strategically, keeping the running total from exceeding 101 on their turn.
It’s popular because it can be played regardless of age and flexes to different group sizes.
It also doesn’t take up much space, so it might be nice to have a set at home.
Othello

Board games that are easy to play indoors are popular, aren’t they? A classic among such board games is Othello.
It’s such a well-known game that an explanation of the rules might be unnecessary, but just in case: you place black and white discs on the board and flip the ones you’ve sandwiched.
These days there are Othello smartphone apps, so it’s become easy to play.
Card game ‘Robo 77 (LOBO 77)’

Players take turns playing numbered cards and adding to a running total.
If you make the total reach 77 or higher, or land on a double (matching digits like 11, 22, etc.), you lose.
Some cards have negative numbers, some double the total, and some reverse the direction of play.
It looks simple, but it actually involves a lot of reading your opponents! The pace is brisk, which pulls you in and can get surprisingly intense.
Although it’s themed as “for adults,” it’s also great for families with elementary school kids since it’s good practice for arithmetic.
Jenga

Jenga is a classic game that’s great for playing indoors.
It may be a classic, but once you try it, it always gets everyone excited—there’s a reason it’s a staple! These days, there are all kinds of Jenga variations on the market, like Love Jenga that’s perfect for mixers and Punishment Jenga for forfeits.
Choosing one that suits the occasion will make things even more fun.
chess

If you’re looking for a brainy recreation, I also recommend chess.
Chess is similar to shogi in terms of rules, but there are differences, such as the types of pieces and the fact that you can’t reuse captured pieces.
How about inviting a friend and practicing together as beginners? Plus, chessboards and pieces look cool, so they make great interior decor—you can enjoy just having them on display at home.
Trump Card Game “F Card”

When you get together with friends and find there’s nothing to do—no games everyone can play—playing cards come to the rescue.
Almost every household has a deck, and you can easily pick one up at a 100-yen shop, making them a go-to for casual fun.
This game uses a standard deck of cards.
Players lay down cards from their hands; the one with the lower number loses and takes all the cards on the table.
Anyone who runs out of cards in their hand is safe and out of the game.
It’s a simple game, but it gets exciting and surprisingly tricky as you factor in your opponent’s and your own remaining cards.
You can even play with just two people.
