Cooperative games you can easily play indoors (11–20)
Mirror stretch

This is a recreation activity where you face each other and mirror the other person’s movements.
Decide who will be the “human” and who will be the “mirror” with rock-paper-scissors, and the mirror person imitates the human’s movements.
You can also choose a theme for the movements.
In this game, concentrating on the other person’s expressions and movements fosters a sense of unity, while also training you to read the other person’s intentions.
LEGO

Block toys are often thought of as children’s playthings, but they’re also excellent for boosting teamwork among adults.
Concretely, you set a problem, and everyone proposes block-based solutions to solve it.
Then the group consolidates around one idea, builds it, and gathers feedback—this is the overall flow.
Simply engaging seriously with kids’ blocks becomes a recreational activity that lets you review your work process, so it’s highly recommended for improving team cohesion.
Board game ‘ito’

Ito is a board game where you progress through the game by talking with each other.
“Ito” means “intention,” and the game is about deciphering others’ intentions while playing, which helps deepen teamwork.
Ito includes two types of games, but if you want to build teamwork, we recommend “Kumonoito,” a fully cooperative mode where the whole team works together.
First, each player draws one card from the deck and secretly checks the number on it without showing others.
Next, choose a discussion topic from the theme cards.
Then, based on that theme, describe your card’s number in words.
After everyone shares their descriptions, reveal cards in order starting with the person whose number seems the smallest.
Through the theme and the words people choose, you’ll learn each person’s values and get a glimpse of their personality—making it the perfect game for getting to know each other!
Brain Matching Game
https://www.tiktok.com/@sanwa_system/video/7478987592403406087Let me introduce a brain-sync game where teamwork is key.
When a prompt is given, everyone should think of a single word that matches the prompt and then say it out loud one letter at a time.
Quick judgment and imagining what words others might come up with are the keys to success.
Even if you don’t all match, the moment you compare answers and see what everyone was thinking is guaranteed to be exciting.
Give it a try and have fun together!

Here’s an idea for an indoor cooperative game that will make even adults burst out laughing: “Say One Thing, Do the Opposite.” Participants link arms and, except for the person giving directions, everyone moves together as one team.
They respond to commands like “Right!” or “Crouch!”—but the movements must be the opposite.
If the command is “Right,” the team shouts “Right!” while moving left.
If the command is “Crouch,” they shout “Crouch!” while jumping, and so on.
The mismatch between voice and movement creates delightful confusion and a chain reaction of slapstick chaos—the game’s biggest appeal.
When the pace clicks, it feels exhilarating; when it doesn’t, it’s guaranteed hilarity.
It also builds team cohesion, making it perfect for icebreakers and recreational activities.

Here’s an idea for a “shape transmission game” that you can start right away with just paper and a pen.
This game is a recreational activity that lets you enjoy both how to convey and how to interpret words.
One person looks at a shape and describes it using only words, while the others try to draw the same shape based on that description.
Questions are allowed, but there’s a time limit, so the key is how efficiently you can align your understanding.
The best part is comparing the finished drawings at the end.
They’re often more off than you expect—or oddly similar—which leads to laughter, applause, and lots of excitement.
It naturally sparks conversation, making it a perfect icebreaker.
Co-op games that are easy to play indoors (21–30)
Captain’s Decision

Consensus is a word that means “agreement.” There are many possible situations, but in a consensus game you face a particular challenge.
In this case, while you’re at sea, visibility becomes poor, and by the time you spot another ship’s silhouette, a collision is already unavoidable.
As the captain, you must address the given items in the optimal order.
Your group discusses and decides that order.
At the end, you compare the model answer with your group’s answer and calculate the rank difference for each item.
The group with the lowest total difference wins.
