This little puzzle was made by a 7 year old boy and is known as one of the hardest math problems ever.
Can you figure it out? We'll see.

You arrive on an island that has three tribes: the Truthies who must always tell the truth, the Falsies who must always lie, and the Unpredictables who can say what ever they want. In order to continue on your quest you need to figure out which tribe is which. You are taken to a tent where the Chief from each tribe is sitting in a circle, we'll say in thrones numbered 1, 2 and 3. They are busy so you only get to ask each Chief one yes/no question, the same yes/no question. AND even though they understand your "pig snout language", as one of the locals put it, they refuse to speak it. So they will answer DA or JA, their words for yes and no BUT you don't know which means which.
What question do you ask to find out which Chief is from which tribe.
Can you do it asking only 2 of the 3 Chiefs?


I'll release the answer when this gets unactive or when someone guesses it right. NO hints will be given.


Goodluck:y:

Looking for Suzzy
It wasn't created by a 7 year old. I remember an alternate version and I found out the answer. I did it like a year ago and forgot the answer. It has to do with, TELLING one of the to do something, and also asking what your name is. cuz if the liar tells your name wrong you know.

"If I were to ask the Chief to your left if you could tell the truth would he say 'Awesome faceA'?"

EXPLINATION:

I'll notate them as:
Truthie: T
Falsie: F
Mixed: M

So there are 6 possibilities:

seat:| 1 | 2 | 3 |
------------------
a: | T | F | M |
b: | T | M | F |
c: | F | T | M |
d: | F | M | T |
e: | M | T | F |
f: | M | F | T |

I'll translate "Chief to your left" to a number for ease.

Question 1: to Chief #1: "If I asked #2 if you could tell the truth would he say 'Awesome faceA'?"

Now here is the third crux: the Truthful Chief ALWAYS tells the truth and the False Chief ALWAYS lies so if either of them don't know then they can not answer.
So if #2 is the mixed chief then you will get silence to Question #1. Giving you three possible answers to the yes/no Question which is how you can get 6 possibilities out of only 2 Chief's answers.

Q1 answer #a: Silence:
seat:| 1 | 2 | 3 |
------------------
b: | T | M | F |
d: | F | M | T |


Question 2#a :
If silence to Q1 then you ask the same question to seat#3, 'to your left now means seat #1 so: "Seat #3: If I were to ask #1 if you could tell the truth would he say 'Awesome faceA'?"

If DA = yes
seat:| 1 | 2 | 3 |
------------------
b: | T | M | F | = DA
d: | F | M | T | = JA


If DA = no, same result
seat:| 1 | 2 | 3 |
------------------
b: | T | M | F | = DA
d: | F | M | T | = JA


I'll explain:
---If DA = yes-----------------
seat:| 1 | 2 | 3 |
------------------
b: | T | M | F | = DA: 3 can't tell the truth, 1 would be honest and say no translating to 'JA', 3 then lies about weather 1 would say 'Awesome faceA' and says yes translating to DA.

seat:| 1 | 2 | 3 |
------------------
d: | F | M | T | = JA: 3 can tell the truth, 1 would lie about that and say no which translates to 'JA', 3 is then honest about weather 1 would say 'Awesome faceA' and says no translating to JA.



---If DA = no-----------------
seat:| 1 | 2 | 3 |
------------------
b: | T | M | F | = DA: 3 can't tell the truth, 1 would be honest and say no translating to 'Awesome faceA', 3 then lies about weather 1 would say 'Awesome faceA' and says no translating to DA.

seat:| 1 | 2 | 3 |
------------------
d: | F | M | T | = JA: 3 can tell the truth, 1 would lie about that and say no which translates to 'Awesome faceA', 3 is then honest about weather 1 would say 'Awesome faceA' and says yes translating to JA.





Great so what if Q1 doesn't come back in silence:
Then you know #2 is NOT mixed
Let's remember if the answer comes back DA it's a lie, JA it's honest

if Q1 answer = DA (lie) then we know #2 is NOT Mixed and #1 is not Truthie so there are 3 possible scenarios:
seat:| 1 | 2 | 3 |
------------------
c: | F | T | M |
e: | M | T | F |
f: | M | F | T |

Then you ask #2 "If I were to ask #3 if you could tell the truth would he say 'Awesome faceA'?"
If silence then #3 is Mixed and:
seat:| 1 | 2 | 3 |
------------------
c: | F | T | M |

If DA then #2 is Falsie and #3 is NOT Mixed:
seat:| 1 | 2 | 3 |
------------------
f: | M | F | T |

If JA then #2 is Truthie and #3 is NOT Mixed:
seat:| 1 | 2 | 3 |
------------------
e: | M | T | F |







if Q1 answer = JA (truth) then we know #2 is NOT Mixed and #1 is not Falsie so there are 3 possible scenarios:

seat:| 1 | 2 | 3 |
------------------
a: | T | F | M |
e: | M | T | F |
f: | M | F | T |

Then you ask #2 "If I were to ask #3 if you could tell the truth would he say 'Awesome faceA'?"
If silence then #3 is Mixed and:
seat:| 1 | 2 | 3 |
------------------
a: | T | F | M |

If DA then #2 is Falsie and #3 is NOT Mixed:
seat:| 1 | 2 | 3 |
------------------
f: | M | F | T |

If JA then #2 is Truthie and #3 is NOT Mixed:
seat:| 1 | 2 | 3 |
------------------
e: | M | T | F |

Goodluck:y:
