Team-based and Co-op Games (11–20)
Pon-kotsu Paint with Everyone

This is a game where you draw the prompt written on a card using only combinations of circles and straight lines to convey it to the guessers.
Since the rules have players reveal their drawings in order from the fewest strokes, focus on drawing concisely with as few strokes as possible.
If you think the key features of the prompt can be captured with few strokes, it’s recommended to explore ways to reduce the stroke count even further.
It could also be interesting to adopt a strategy of making a higher-stroke illustration that serves as a hint if you predict others won’t be able to extract the answer from earlier drawings.
Let’s draw a picture together!

Even a picture you can draw smoothly on your own becomes very difficult when everyone tries to draw with a single pen.
You might wonder how everyone can use one pen, but you wrap strings around the pen, spread them out like rays, and everyone holds a string.
You move the pen by pulling the strings, but unless everyone matches their strength and the direction they pull, you can’t draw clean lines.
If even one person pulls too hard, the pen can tip over, so it’s quite a challenging group activity.
Try it with simple drawings or letters first!
The cup game that requires cooperation

You can only clear the game if everyone who joins works together! Here’s an idea for a cooperation-required cup game.
It’s great for strengthening class unity and building bonds.
It also takes little prep, so give it a try.
All you need are paper cups, a rubber band, and strings.
Tie one string per participant to the rubber band and you’re ready to go! Aim to clear the challenge by arranging or stacking the paper cups.
The key is controlling your strength!
Picture shiritori

This “Picture Shiritori” is perfect for killing a bit of time, like during your lunch break.
You’re probably familiar with regular shiritori, but in picture shiritori you play it using drawings.
If your drawing skills aren’t great, people can’t tell what you drew, which leads to funny, unexpected connections—that’s part of the charm.
It’s easy to get absorbed in it, so it’s ideal for a quick pastime.
Co-op Challenge

Instead of making it a competition or a face-off, try a “9-person cooperative arrangement” where everyone works together toward success.
The team can have any number of members.
Set a time limit and rules, and aim to achieve continuous successes.
For example, you can dribble like in soccer or basketball and put the ball into a goal, or you can catch a shuttlecock, a small ball, or a paper airplane in a basket.
It’s a valuable experience for both children who are good at these activities and those who aren’t, as they think about how everyone can succeed together.
Earphone Loud Telephone Game

The “telephone game” is fun because the original message rarely makes it all the way to the end! This version cranks it up with loud music.
With music blasting through earphones or headphones, you watch the speaker’s mouth and try to guess what they’re saying, then pass on the phrase you’re confident about to the next person.
When it’s your turn to say it, your voice will be drowned out by the music in your ears, so it’s fine to speak out loud! Choose intense tracks like EDM or hard rock that will completely drown out voices.
It’s especially fun as a team competition to see whether the message survives to the end!
Team-based / Co-op Games (21–30)
Getting lost in snowy mountains

You all joined a tour to see the aurora.
However, the plane you were on crashed due to a geomagnetic storm.
The crash site is in snowy mountains, and the nearest town is as far as 32 kilometers away.
The pilots have died, and the plane has sunk to the bottom of a lake, so you have no choice but to make your way on your own.
Besides cold-weather clothing, you only have 10 items.
To survive, discuss as a group and rank the items from most to least important.
The time limit is 30 minutes; when time is up, present your ranking.
When giving opinions about the ranking, be sure to explain your reasons, and when making decisions, reach a consensus—an agreement among everyone.
