Logic Riddle 65 Demons In a Village Hard Interview Riddle
video description
As your puzzle said that demons are highly and equally intelligent (definitely have different physical capabilities)and does not anywhere
tell that they are not creative. So I assume that they are creative also.
2. Fear of being eaten increases progressively with increase in numbers if certain anomaly happen at some point.
So it starts like this
-If there is only one demon (he will surely eat the sleeping man)
-If there are only two demons ( no one will definitely eat the person because other demon has 100% chance of then eating the demon 2, so group of 2 has 100% probability that they will not eat the sleeping person)
- if there are only three demons( then one of the demon will definitely eat the sleeping person because of 100% group of 2 demons not to eat them)
- if there are 4 demons ( no demon will eat because surety of g3 demons to then eat him)
Similarly pattern follows for G5 and G6 and G7 but things started to getting interested for group of 8 demons.
Now if anyone from the g8 demon eat the sleeping person then the seventh demon will not be able to eat 8th demon as confidently as it was suggested by the odd / even concept because here the concept of randomness is cleverly introduced by the 8th demon so by using this fear 8th demon can safeguard himself from being eaten(as other demon are intelligent so they will not rule out meagre 1% probability of being eaten.
So why this not started from the 4th or 6th demon
- for 4th demon he can not introduce such fear in the mind of 3rd demon because of 100% probability of 3rd demon not being eaten by the 2nd demon.
But why not with 6 ( because simply it is more closer to 4 and then to 2, in short it is more closer to absolute events so the concept of randomness can't be introduced.

Think
I think you approach of generalizing between even and odd is wrong in this problem.
The demon will not eat the man only in the case of 2 demons.
In the case of 4 demons, when 1 demon eat the man and falls asleep, the remaining three will not dare to eat the sleeping demon as if they eat the sleeping demon, then the then remaining can eat him.
So, in the case of more than 2 demons(3, 4, 5, 6, 7, 8, the fastest demon eat the man and falls asleep and the remaining will not eat the sleeping demon.

Great puzzle idea that's poorly presented. Solvers need to know several things at the beginning that are crucially omitted: demons don't die of hunger, demons don't fear acts of nature killing them when they're asleep (animal attacks, buildings decaying and collapsing, etc, the -sleeping forever- idea isn't a problem, demons are not all equally fast (so that the actually can be one who beats the others to someone to eat, etc.

This riddle is missing one important rule. It isn-t enough that the demons be highly intelligent. It isn-t even enough that each demon know all the other demons are highly intelligent. Each demon has to know that all demons know that all demons are highly intelligent (to infinite recursive depth. If even one demon doubts what the other demons might do, the chain is broken and he can-t eat safely.

If demons are odd then also, each demon will think that he has to remain alive just like in even case. So in odd also Nothing will happen in the village and hence no one will eat the sleeping man.
I think I am right. Actually I don't understand your approach, that
in odd case how can you assume that demon will not be eaten by another demon just like in case of even no. Of demons

My solution was a bit different and while it has flaws the outcome is more or less the same. Basically, a demon can move the sleeping human to a place where no one can find it and then eat it and fall asleep. This way, only one demons falls asleep, the rest remain hungry and sleep deprived ) My solution is not clean by any means, but whatever.

I believe that you made a mistake here when you generalize between an odd and even number of demons.
Only when there are exactly 2 demons, no one can eat the sleeping man. With three or more, the fastest demon can eat the man and the rest will not dare to eat the sleeping demon. No matter if the remaining number of demons is odd or even.

But still there will be an issue; the demons are highly intelligent and greedy too. So in case of even number if a demon kills another demon the total number of demon will become odd again and then the killer can eat the sleeping demon. So at the end of the day all demons will kill each other and the village will be free of demons. -

If the demons are highly intelligent, they would realize that sleeping forever and dying are the same thing. So they would not eat anything that would make them fall asleep forever because staying alive is their highest priority.
To get the result you want, you have to make them fall asleep for a finite length of time.

I understand your approach, but in my opinion, a better option would be that the man be cut into 65 equal pieces. (I don't know if there is any way one can do that, but hey, you said that the demons are very intelligent) Thus, no demon would die, and all of them would sleep forever. I think this can be a solution as well.

Let take 9 or 10 demons. Then why any demons take the risk of eating because he knows i will be eaten by other demon because they will think of his life not the last demon.
And if there is an option of happening nothing.
Its simple no one will eat. And noting happens
Unless there are only 3 demons.

This is clearly wrong. In any case other than one demon, some demon will be on the chopping block so no demons eat and it will stop. Odd and even only matters IF it reduces to the case with one or two demons. But this problem does not reduce like that. Why will I ever eat if I am vulnerable?

CONFUSION, CONFUSION CONFUSION MY LIRD. .In case of three demons 1 will eat the man and afterwards 1 more demon will eat the sleeping demon as he knows that he cannot be eaten as you told that if 1st demon is eaten and then one more demon eats him the eater demon cannot be eaten further.

if one demon can eat another demon after eating the sleeping man, then why not the demons eating themselves prior to eating the sleeping man? in this case, there might be 1 demon left and he then eat the sleeping man and sleep himself without tension.

Yeah good but why not eating a demon who has eaten the human but a demon who had fallen asleep or just kill one an eat it. If you are creative you cam find solution. Btw i want comments on this beacuse I wana know your oppinion, beacuse maybe I am wrong.

If the demons can eat other demons, I expect them to fight among themselves (taking a 50% risk of losing) over a 100% risk of dying by feeding from the man.
Though a demon might also hide, fooling others into thinking the odds are favorable.

Why is that in case of even demons, one of them would not eat the person and why in odd case it would eat. And if there is a possibility of demon to choose to be in hunger permanently, then the initial info is insufficient and misguiding.

Alternatively, - because they all figured this out - they could wait until 32 of them pass out and the rest can eat them, and the last one can eat the man because all the other demons are satisfied so he would be safe. 33 healthy demons

-paused the video at 1: 30.
my answer:
the way i see it.
if there are an ode number of demons the man will be eaten and if even then the man will not be eaten.
so he will be eaten and 64 demons will stay hungry

I have a doubt. You initially told that demon's life is highest priority. So demon knows that if it sleeps it would be eaten. So why any demon will eat the sleeping man because it knows that it would be eaten.

I realize it's out of the context of the riddle, but if these demons are intelligent they'll figure out there's no-to-little food here, and leave since there's nothing keeping them in the village.

I didn't consider nothing happening as an option because I thought they were all out to find some way to eat and not die. I was trying to think how they could do this. Maybe I thought too much into it.

Think like a demon. then 'solves' it with logic and rationale instead of trickery and lies. Are you sure you're following the 'think like a demon' rule? -

I have actually lived this exact scenario, because I am a demon, what happens is that all of the demons eat some pussy and then the man wakes up and eats some as well.

First of all i personally didnt like it that much. but with my logic its already obvious that the man is going to die, its better to die than being half dead.

I think you should have added that when multiple demons want to eat the man at the same time, the fastest/an arbitrary demon gets to eat the man.

As always it was a great riddle.
But not all viewers are as intelligent as demon.
As always they are unable to understand the answer.
