Fun for communication! Pokan Game

Words that seem obvious to you can be completely unclear to everyone else—what do they even refer to? In the “Pokan Game,” you guess the true topic hidden behind such words through conversation.
First, the person who’s “it” gives a single-sentence line or phrase as the prompt.
The others then figure out what it refers to by asking the leader questions and proposing guesses.
It’s best to choose prompts that aren’t easily solved, ones that require some real thought.
Talk a lot and deepen your bonds as you play!
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?
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.
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.
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.
Runaway Trolley and Workers

A consensus game themed on a thought experiment proposed in 1967 by British philosopher Philippa Foot.
There are multiple workers on a railway track, and unless something is done, a major accident will occur; if you flip a switch, you sacrifice one person to save many lives.
Should you flip the switch, or leave things as they are? The key is first to consider the dilemma individually, then to reach a single conclusion as a group.
Because differences in positions and values become clear, it’s a compelling topic that sparks lively discussion.
Six patients and medicine

It presents the ultimate choice: help one critically ill patient or save five moderately ill patients.
There is only one dose of medicine; the critical patient needs the entire dose, whereas the moderate patients can all survive if it is divided among them.
The dilemma of valuing a single life versus prioritizing the many exposes one’s values.
Key discussion points include whether all lives are equal in weight or whether social roles should be considered.
It is important for the whole class to debate and work toward a single final decision, making this a thought-provoking theme that lets students experience the challenges of ethics and difficult choices.
