![[Logic Puzzle] Escape from a Room with Only Chairs](https://i.ytimg.com/vi/ZQ7lagRdC3o/sddefault.jpg)
This is a puzzle where ten men locked in a room aim to have everyone escape by meeting certain conditions.
In a room with only a chair, they take turns acting without any ability to communicate, and we consider a method for escaping under those constraints.
The available actions are either to rotate the chair 90 degrees and continue, or to destroy it to release the people who have entered the room up to that point.
The key is how to convey the number of people using these limited actions.
Rather than having everyone try to judge the situation, it’s better to assign one person as the counter; using changes in the chair’s orientation to keep count may be the optimal approach.

It’s not just about having knowledge; it’s a quiz that tests your ability to organize information—your IQ.
It’s crucial to read the problem statement carefully, sort out the conditions clearly, and work your way toward the answer from there.
If you check what’s being asked one by one, you can arrive at the correct answer, but how well you can simplify your thinking shows each person’s intelligence.
Some people aren’t good at organizing, so it’s also a good idea to provide part of the calculation method as a hint and have them think from there.
How many squares are there?
A puzzle presents a figure that looks like a row of quadrilaterals and asks you to figure out how many quadrilaterals are in it.
Because the figure is made of arranged quadrilaterals, you might be tempted to just answer with the number lined up, but the challenge is to see how you can use your head beyond that.
A square isn’t the only type of quadrilateral, so let’s consider what kinds of quadrilaterals can be formed using this figure.
Examples like figures made of rows of triangles or illustrations with circles in a line are given to demonstrate ways of thinking, so it’s also important whether you can adapt your approach from those examples.
