The Hardest Logic Puzzle Ever

I have to go back to “Will he tell me that this door leads to the castle at the center of the Labyrinth?” and then work from there.

Hey! Aren’t these guys all Congressmen? They sure sound like they are.

Smullyan — not Sullyman.

Ask each person if the third person is Chaos. If the first two answers are the same, ask the third person if the first (or second person) is Chaos. I’m not going to list out all my handwork, but I think that system works.

All i know is never get involved in a land war in asia.

When figuring out the identity of the guardians, do you still, also need to figure out which road to take? That would require a 4th question, right?

With two people you ask which way to your village. The liar will point to the truthful village and the truthful one will point to his own village so they will both point the same way.

With two people, I think the question is “which way will he tell me is safe” and the answer will be the way to danger. This question is much harder because if you go to the original post, there is a clarification that the Knight and Knave do not know whether Chaos will answer truthfully.

At what point do logic puzzles become so convoluted and arbitrary that they pass from intriguing to nonsensical? Wherever that point exists, this one has blown past it with the speed of an unladen sparrow.

The answer is 42.

I think this is the answer:
Ja=yes Knight Knave Chaos (truthful)
Are you Chaos? da ja ja
Does Ja = yes? ja da ja
Does Da = No? ja da ja

Ja=yes Knight Knave Chaos (lies)
Are you Chaos? da ja da
Does Ja = yes? ja da da
Does Da = No? ja da da

Ja=No Knight Knave Chaos (truthful)
Are you Chaos? ja da da
Does Ja = yes? ja da ja
Does Da = No? ja da ja

Ja=No Knight Knave Chaos (lies)
Are you Chaos? ja da ja
Does Ja = yes? ja da da
Does Da = No? ja da da

So if one answers the same for all 3 questions while the other two answer different for 1 & 2 then the one that answered all the same is chaos and Ja is yes, then you know who knight and Knave are.

If two answer the same for all three then the one that didn’t is Chaos and Ja is no and the one that agreed with Chaos on question 2 is Knight.

Anybody see anything wrong in the logic?

@ Cluck: No you have three questions MAX and you must ask EACH knight ONE question. You can’t ask three questions and have all three answer each one.

So questions only? No waterboarding?

My brain is full. May I be excused?

wow…all you have to ask is one question to all three. A question that you know the answer to (is green grass green?). You can figure out who is telling the truth from that. Then ask a fourth question to the person that was telling the truth about which path is safe. This is a logic question that states you can only ask three questions without giving the reason for that. Actually, you can ask as many questions you like.

Is green, green? Logic…understand logic. If someone tells you to use logic to answer the question, then anything is a possibility.

I wish Spock was here to tell us either the answer, or to eloquently inform us as to why the puzzle itself is ILLOGICAL.

You stab all three and take the fourth path.

What fourth path? The path you just came down to reach where they are.

Ask Guardian A, “If I asked you, “Are you Chaos?” in your current mental state, would you say “ja”?”
If A answers “ja”, he’s Chaos. Then ask Guardian B, “If I asked you, “Are you Knight?”, would you say “ja”?”. The answer is “ja” if B is Knight, and either way the problem is now solved.

If A answers “da”, he’s either Knight or Knave. So ask him instead, “If I asked you, “Are you Knight?”, would you say “ja”?” If the answer is “ja” he’s Knight; otherwise he is Knave.
So, now, ask him “If I asked you, “Is guardian B Chaos”, would you say “ja”?” If he answers “ja”, B is Chaos, and C is the opposite of A. If he answers “da” then C is Chaos and B is the opposite of A.

If yes they nod their heads, if no they shake their heads. Local language irrelevant.
