Games (11–20)
Countdown
The Count Game is a very simple game for two or more players where you lose if you say a predetermined number.
Children old enough to say numbers can play.
To start, decide on the number that must not be said.
Then count upward from 1 toward that number in order.
Each player can say at most three numbers in a turn, so you have to think ahead as you answer.
It’s great mental exercise—give it a try!
Last-Player-Standing Grand Strategy
Introducing ‘The Last One Standing: Luck and Logic,’ a strategy game of chance and brains.
It’s playable by 2 to 4 people.
First, each player chooses a color.
Then, in turn, place one ball of your color anywhere you like, one at a time.
After all balls are placed, play rock-paper-scissors to decide the order for pulling the lever.
When you pull the lever, balls will drop.
The player whose ball(s) remain until the end wins.
It’s both brainy and exciting—highly recommended!
Number puzzle
There are many types of number puzzles, and the one I’m introducing here is a number puzzle where you match the same numbers.
Anyone can make it with paper, a pen, and scissors.
First, prepare a square sheet of paper and fold it so that it’s divided into 16 equal sections.
Then, write the numbers 1–8 in designated positions on both the front and back.
Next, make cuts with scissors along the vertical fold lines in the second and third rows.
That completes the number puzzle.
After that, simply fold it so that four of the same number come together! Try to think flexibly and give it a go.
chess
Chess is a two-player board game and a type of mind sport.
The first and second players each use 16 pieces of six different types to corner the opponent’s king.
Even if you know what chess is, you might feel that the pieces’ characteristics and the rules seem difficult and hesitate to get started.
But if you change your perspective, once you learn those basics, it’s a game you can enjoy almost indefinitely.
Why not take this opportunity to give it a try?
mosquito
Let me introduce “Mosquito,” a game where you take on roles and battle while doing calculations.
How about splitting into Spiders and Mosquitoes and trying a game that uses simple arithmetic? Even if you’re not confident with math, it’s easy to jump in because it feels like a game.
All you need is paper and a pen.
The calculations use multiplication, so anyone with basic multiplication knowledge can play—that’s part of the appeal.
By playing while thinking about tactics and strategy, you can develop planning skills, flexibility, and problem-solving ability.
Rubik’s Cube
A Rubik’s Cube is a square toy whose pieces rotate vertically and horizontally.
I’m sure many of you are familiar with it.
The way to play is to align the scrambled colors so that all six faces become a single color.
You can’t solve it by turning it randomly, so you need to think as you move it.
It seems the trick is to start by making a cross! It’s highly recommended—finishing it feels incredibly satisfying!
Games (21–30)
codename
Let me introduce the word-association game “Codenames.” First, you need two players and one guesser.
Prepare 25 cards, each with a codename written on it.
The guesser must not see the contents of the cards.
Of the cards, 9 belong to the first team, 8 belong to the second team, and 7 are bystanders.
The players give the guesser a single word that will make them associate with their own team’s agents.
The side whose agents’ codenames are all identified first wins.
One remaining card is the assassin; if you lead the guesser to that codename, you immediately lose, so be careful.
It’s a fun game where everyone gets to use their brains.
