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.
A game developed by NASA

Let’s try playing a game developed by NASA, the National Aeronautics and Space Administration.
To briefly explain the game: it assumes a situation where a spaceship has malfunctioned, and you rank 15 items you have on hand.
You assign ranks in order of necessity, and decide them through group discussion.
First, each person should make their own ranking based on their interpretation, and then discuss and reconcile the differences with the group.
Can you determine the correct order—and survive?
Minority wins! The Minority Game

This is a game where the people who choose the minority—the less popular answer—win.
First, split into groups and set a prompt and two choices.
Since there are only two options, pick one based on your own thinking.
After choosing, hold a debate—i.e., a discussion—within your group about the prompt.
After the discussion, think again about which option to choose as your answer, then everyone reveals their choice at the same time.
If you picked the minority answer at that moment, you win; if you picked the majority answer, you lose.
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.
Southern Cross Expedition

It’s an exciting theme where you become a member of the Southern Cross Expedition Team and go on a treasure hunt.
It begins when you receive a message from a teammate saying, “I found treasure on a southern island, but it’s heavy—please help.” However, communication is cut off partway through, and the story revolves around completing the remaining map.
Each member holds different pieces of information, and you can’t reach the answer unless everyone shares what they know.
The key is not to keep your own information to yourself, but to share it and work cooperatively with your teammates.
While enjoying the fun of deduction and organizing information, you also learn the importance of trusting your companions.
The very process of completing the map through repeated discussions is a stimulating theme that lets you experience a real sense of accomplishment.
Territory game! S-Ken

A game called “S-Ken,” where teams compete to steal a treasure from territories drawn in a large S-shape.
Participants split into two teams and start from their respective sides.
Decide roles in advance: who will defend your territory and who will steal the enemy’s treasure.
When the start signal is given, move by hopping on one foot from outside the S to the enemy’s territory.
Once you enter the enemy’s area, you can move with both feet, so quickly grab the treasure.
The square spaces near the enemy territory are safe zones where you can stand on both feet and rest.
Those in your own territory should push enemies out of your area and protect the treasure.
The treasure can be anything like a stone on the ground.
Finding commonalities

Common-ground finding is a fun game that helps you talk with people you’re meeting for the first time and feel closer to them.
There are various ways to play: for example, participants form pairs or groups and, within a time limit, look for things they have in common through conversation; or they present common points they’ve written down in advance—those are standard approaches.
Conversations can stall without a prompt, so set simple topics like “How you spend your days off” or “Favorite foods.” It’s also a good idea to set a target number of commonalities to find beforehand.
