Rock-Paper-Scissors & Variety Games (1–10)
Growth Janken

Grow bigger when you win at rock-paper-scissors! Here’s an idea for a Growth Rock-Paper-Scissors game.
Start in a crawling pose like a baby! Each time you win, you “grow”: from a crouching child to a standing adult.
You can play one-on-one, of course, but it’s also great fun with a large group.
To keep it fresh, try tweaking the pose you strike when you level up, or set rules like not playing rock-paper-scissors with the same person consecutively.
That way, everyone can enjoy it without getting bored!
Number Jump

Let’s play using both our heads and our bodies! Here’s an idea for a game called Number Jump.
Kids tend to get more excited by games that are a bit challenging rather than too easy.
How about trying Number Jump, a game that engages both the mind and the body? It’s best to start with five or more people and go over the rules slowly as you begin.
First, each person jumps one at a time while saying “1.” After the last person has jumped, switch to jumping in pairs while saying “2.” In this way, the number of people jumping at once increases, so it’s a game that requires concentration.
Give it a try!
Pyramid Rock-Paper-Scissors

Perfect for class or grade-level activities! Here’s a fun idea for Pyramid Rock-Paper-Scissors.
Rock-Paper-Scissors is a simple, classic game that always gets everyone excited, and with a few tweaks, it becomes even more engaging for kids! After splitting into Defense and Offense teams, the Defense team stands on the lines drawn in a pyramid shape.
The Offense team aims to defeat the King by playing rock-paper-scissors against the Defense team and advancing with each win.
A key rule for the Offense team: if you lose a round, you must return to the starting point!
Newspaper Rock-Paper-Scissors

Defend your territory! Here’s an idea for a newspaper rock-paper-scissors game.
It’s simple yet tense! Each participant stands on a sheet of newspaper, and if you lose a round of rock-paper-scissors, you fold your newspaper.
As the paper gets smaller, it becomes harder to keep your balance, adding to the excitement.
As the game goes on, players drop out, so you’ll need caution and a competitive edge to be the last one standing! It’s a fun idea you can enjoy with friends and family while getting everyone pumped up.
Aiko, then go!

Let’s enjoy a reflex-based game! Here’s an idea for Aikode-Don.
This is a one-on-one game where you face each other and start in a seiza (kneeling) position.
With rock-paper-scissors, people usually focus on winning or losing, but in this game the key moment is when it’s a tie! The instant you both throw the same hand (a tie), try to stand up faster than your opponent! Once you get used to the game, try changing the sitting style to gym sit (hugging knees) or long sit with legs extended.
You can also increase the difficulty by adding a rule that you must stand up without using your hands!

Play with letters! Here’s an idea for “A-I-U-E Balls.” It’s a letter-play activity perfect for anyone planning a game with colored balls.
You’ll need a large basket, colored balls, masking tape, a permanent marker, and a smaller basket for collecting the balls.
First, write each of the 50 Japanese syllables on pieces of masking tape—one character per piece—and stick them onto the colored balls.
Once you put the balls into the large basket, you’re ready to go! Give the kids a prompt, then have them search the large basket to find the letters one by one.
It’s a thrilling, heart-pounding activity that’s lots of fun.

Perfect for class events and grade-wide recreation! Here are game ideas for everyone.
These unique ideas are great for grabbing the attention of children in a group or filling short breaks.
The teacher acts as the leader and gives the children instructions for actions.
However, they should only follow actions that include the phrase “everyone.” Well-behaved children tend to follow every instruction the leader gives, but the rule is to follow only the instructions that include “everyone.” Try using this when you want them to focus.

If you win rock-paper-scissors, throw the ball and try to tag your opponent! Here’s an idea for a ball battle game.
It helps develop decision-making, quick reactions, and control.
The rules are simple: whoever wins rock-paper-scissors holds a colored ball and tries to hit their opponent with it.
The player who loses should move quickly and dodge to avoid getting hit.
It’s a unique and fun game that’s sure to fill the air with laughter before you know it!
Psychological rock-paper-scissors
@cocoskip♪ Original song – Yuzu (๑′ᴗ‵๑)♪ – Yuzu (๑′ᴗ‵๑)♪
A new twist on invisible rock-paper-scissors! Here’s an idea for psychological rock-paper-scissors.
In this game, you face each other with a wall between you so neither can see the other’s hand.
Talk it out with lines like, “I’m throwing ___,” or “Are you throwing ___?” and try to guess what your opponent is showing.
You can change your throw until the time limit is up.
When time’s up, who’s winning? It’s a thrilling, heart-pounding way to play.
Candy scooping

It’s a game where you scoop up candy with a paper-covered “poi,” just like the classic yo-yo fishing or goldfish scooping you see at festival stalls.
Doing it in a bath or pool makes it feel out of the ordinary and fun, doesn’t it? With your favorite treats right in front of you, can you keep your cool and use the poi to scoop them up?
