Indoor games that get you moving (31–40)
A number-guessing game that everyone can enjoy, from children to adults

The number-guessing game, where communication skills and powers of observation are key, is a game that large groups can enjoy.
The rules are simple: on the cue of “Ready, go!”, players take turns calling out the next number.
Each person also decides, at that same cue, whether to stand or sit.
If the number called does not match the number of people standing, the game ends there.
Because you have to observe others and decide which number to call while watching your opponents, the key is not to succumb to tension or pressure.
Give it a try!
Play the Signal Game Indoors!

The “Traffic Signal Game,” where everyone follows the leader’s instructions, is a play activity that can help develop the ability to listen carefully and the judgment to act immediately.
When the signal is blue, take one marching step; when it’s yellow, shake your head left and right and look around; when it’s red, squat down.
Listen closely to which color the leader calls and act accordingly.
If the leader calls a color other than the three, everyone says “nai-nai” (meaning “no such color”).
There’s no winning or losing in this game, so just have fun moving your body!
Rock-Paper-Scissors Game Jump!

Participants split into two teams and face each other from opposite ends of the room.
When the signal to start is given, play rock-paper-scissors with a teammate; those who win move toward the opposite side by jumping.
Once you reach the other side, play rock-paper-scissors again, and repeat.
It’s a very simple game, so incorporate different types of jumps for the movement: a “rock” jump where you hop with both feet together, then a “scissors” jump that’s like practicing skipping, and next a “paper” jump with your legs spread wide.
It feels like you’re evolving as you go, and it’s a lot of fun.
Enjoy instantly! “Shingenchi Game”

Choose one person from the players to be the guesser.
The remaining members decide who will be the “epicenter,” then either stand in front of the guesser or form a circle with the guesser at the center.
At the start signal, the epicenter naturally strikes a pose—anything is fine, such as folding their arms, switching their pivot foot, or scratching their head.
The other members, with a slight delay, imitate the epicenter’s pose.
The guesser must observe who started the pose and identify the epicenter.
Ball games you can play with two people!

Balls are very familiar playthings for children, and the ways to enjoy them are limitless! This time, we’re introducing eight ball games for lower-grade students.
In addition to balls, items like hula hoops are used to help kids improve their physical abilities while having fun.
Basically, children pair up in twos and play by throwing or rolling the ball, or dodging a bouncing ball.
There are also games with sport-like elements—such as Copycat Dribble, Hoop Pass Tennis, and Marker Hockey—so we hope even kids who feel uneasy about ball sports will take this opportunity to get interested.
Don’t make a sound! The Silent Game

The no-noise game, where even the slightest sound means you’re out, is a fun activity for everyone from small children to adults.
You can use anything as the subject, but simple, everyday items like plastic cups make preparation easy and help you enjoy it casually.
Try focusing your attention and being extremely careful to avoid making sounds while getting creative with tasks like stacking paper cups, wrapping with tissues, lining up juice cans, or folding aluminum foil.
Once you get used to the game, it’s also recommended to add a time limit or use paper bags to increase the difficulty.
Gorilla Game

Let me introduce a game that will have your class roaring with laughter: the Gorilla Game.
Choose one child in the classroom, and have them answer every question from the questioner with the word “Gorilla.” For example, if the question is, “What did you eat for breakfast today?” the child answers, “Gorilla.” Of course, the questioner should react with a funny comeback to the “Gorilla” answer.
This back-and-forth will make the kids burst into laughter.
Make sure the final question sets up a punchline.
Also, the questioner’s reactions are key—add some facial expressions to make it even more exciting.
Bomb Game

Children dash past, laughing, “Run for it!” That’s the thrilling scene of the Bomb Game.
Place mats for the start and finish, and if you make it across while dodging the rolling balls, you succeed.
The rules are simple, but by gradually increasing the balls’ speed, throwing in feints, or changing the timing, it stays fresh and exciting every time.
Each playthrough builds problem-solving—“How should I dodge?”—and trains not only physical ability but also reflexes and concentration.
It’s safe to play indoors, and the easy setup is another big plus.
Reflex Game

We’d like to introduce an idea for a group game called the “Quick-Reaction Game,” perfect for after-school programs because the rules are simple and you can adapt it freely.
The basic rule is: when the leader meows like a cat (“meow”), the children must immediately raise their hands.
That alone is simple, but by mixing in feints—like a dog’s bark or a wolf’s howl—you add just the right amount of thrill and laughter.
You can also use instruments instead of animal sounds.
For example, the bell sound means correct, while castanets or a tambourine indicate a trick.
Using familiar instruments makes it fun while building focus and reaction speed.
It’s a highly adaptable, recommended game that you can play over and over, adjusting for different ages and group sizes.
A rhythm game that toddlers can enjoy

Moving your body to songs and rhythms can really lift your spirits, right? It introduces games that are fun even with large groups, like “Kaminari-don,” “Yakiimo Goo Choki Paa,” “Anpan Shokupan,” and “The Greengrocer’s Shop.” The rhythm game “The Greengrocer’s Shop” is a unique activity that fosters memory, concentration, and the ability to recall familiar items based on a theme.
How about trying it at events with preschoolers? It’s full of fun ideas that people of all ages can enjoy.
