(adsbygoogle = window.adsbygoogle || []).push({}); So hello there! =D Today I'm asking from NGU community one challenging but simple riddle. I will +rep and give some vBux for the first who can solve this.

We are in prisoner. There is three prisoners in ''shape of triangle'' on the prisonyard. There is 2 white cats and ''unlimited'' amount of black cats in the yard. There is ONE cat behind every prisoner.

- There is ONE prisoner with WHITE cat behind his back.

- Other TWO prisoners have BLACK cats behind their back

- Prisoners can't see which color of cat they have behind their own back.

- ..But prisoner can see behind other prisoner's back.

- Prisoners can't communicate any way.

- They can't move or use anything!

- Prisoners know the fact that there is only 2 white cats and unlimited amount of black ones in the yard.

Prison warder says to them that first one who can solve which color of cat does they have behind their back is free'd from jail. He must explain how he got the answer without watching behind.

So, question to you, my friend is that who is the prisoner who got the liberty? And also explain how you got the answer.
I tell it if no one cant figure it out.

Good luck!

EDIT: Oh so thanks to L3G1TxXZ4LUD3K ! He noticed that there is other answer to this riddle aswell! But yeah there is still no answer for the other way what I meant to be.

Answer #1: There is cats in the yard, right? The one with black cat COULD see white cat running in the yard. And in the triangle he can see that there is white cat behind one prisoner. SO he could yell ''I'm free! I haz teh black cat!'' and get his liberty until he ends up jail again. Smile

Answer #2: (Way I meant it.) So basically free'd prisoner is either #1 prisoner with black cat or #2 prisoner with a black cat. Why? Well prisoner with black cat can see prisoner with white cat and other prisoner with a black cat. Other prisoner with a black cat can see same thing. Prisoner with black cat said that he haves black cat because other one with black one didnt say anything. Reason is that he only saw white and black cat. Then the other prisoner got it because other one would have said something. I mean like if he can see 2 white cats, he would have know the answer. But when he didnt, other one got it. Mindrape, eh :carling:

No. You said that one prisoner can see two others that they have white cats. But I already said that there is only one white cat behind one prisoner so other one is roaming somewhere else! Happy

What are you talking about? You wrote it wrong then because you said there's only 2 white cats & the question is which prisoner will be freed & it has to be the one that has a specific color or mixed color in which would only be white or black & I said it can go three ways like let's say the prisoner can see that he can see both white cats behind the other prisoners says "I have black cats" & if the prisoner says that he only sees black cats behind the other prisoners says "I have white cats" & if there's a prisoner that sees only one white cat behind a different prisoner then he says he has 1 white cat & the rest black.

Dude:

''We are in prisoner. There is three prisoners in ''shape of triangle'' on the prisonyard. There is 2 white cats and ''unlimited'' amount of black cats in the yard. There is ONE cat behind every prisoner.

- There is ONE prisoner with WHITE cat behind his back.

- Other two prisoners have BLACK cats behind their back''

So, there is TWO WHITE CATS in TOTAL there in the yard.
And:
''There is ONE prisoner with WHITE cat..''
''Other TWO prisoners have BLACK cats...''
U got it?

Try and explain the situation a bit better =D

They are standing in a triangle in a prison yard, there's a white cat behind one of them, black cats behind the other 2....the 2nd white cat and the rest of the unlimited black cats are where? Just walking around the yard?

Well it doesn't matter. You just need to know that there is 2 white cats total and unlimited amount of black cats.

It does matter doesn't it? Like someone said previously, if the 2nd white cat is in the yard then the prisoners could look around, find the 1 white cat, look at the other 2 prisoners and then know what color they have.

For example if I am the one with the white cat, I look at the other 2, they have black cats..i look and see the 1 white cat in the yard, then i know i must have a 2nd white cat behind my back?

lol :carling:
