Who said the Stab Guard has a true sense of complex? He could just stab you anytime. [[User:Dontknow|Dontknow]] ([[User talk:Dontknow|talk]]) 00:37, 16 March 2017 (UTC)

What's wrong with "Are you gonna stab me?"? They'll either answer or not and stab you or not, that's around 2 bits, which seems like it should maybe help decide in a space of 3. I ask Lie, he says yes, yet doesn't stab me. I ask True, he says no, and doesn't stab me. I ask Stabby, and he says no and doesn't stab me because it's a really simple question.

Here's a solution, but it's quite stupid, and might not work, depending on if the guards appreciate their mothers:

"What would you say is the way out?" It doesn't seem tricky, but it's actually a meta-question. The guard knows what they would say is the way out. If the guard tells the truth, they would say the correct door. The guard tells the truth about telling the truth and says the correct door. If the guard lies, they know they would lie about what the correct door is. The guard lies about lying and says the correct door.

Assuming there are three doors (as shown in the picture), at least one door leads out, and at least one door does not, the single non tricky question of "Which doors lead out?" will always yield a useful answer. For two safe doors, if two door are pointed at, they are safe. if one door is pointed at, it's deadly. If only one door is safe, it's the opposite.  If there are only two doors, (as in the standard puzzle) there's nothing you can door, as any question that both the liar and the truth teller would answer identically and tells you which door to go through is a tricky question.

:Assuming only "door 1" leads out and I ask the liar "which doors lead out?", he may give any answer apart from "door 1", e.g. "all doors" or "doors 1 and 2" - this is not helpful. Similarily for 2 safe doors the answer to "which doors lead out?" could be a lie without of being the complete opposite of truth. (e.g. doors 1/2 lead out, liar could say 1/3 lead out - not useful) --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 07:56, 3 May 2021 (UTC)
 
 
My friend Umnikos came up with a solution for the version where the stabber acts randomly or adversarially for nontricky questions (tricky questions are those that could be used on their own to determine whether the stabber is lying, or to extract information without knowing whether someone is lying).
 
 
Q1: "does door 1 lead to freedom?"
 
 
Two guards will answer in one way, the third in another.
 
 
to the third, unique guard:
 
 
Q2: "if I asked you if door 1 lead to freedom, would you say yes?"
 
 
Q3: "if I asked you if door 2 lead to freedom, would you say yes?"
 
 
Q4: "if I asked you if door 3 lead to freedom, would you say yes?" [[User:AndrewTheXKCDer|AndrewTheXKCDer]] ([[User talk:AndrewTheXKCDer|talk]]) 18:49, 26 June 2021 (UTC)
 
 
;Does the actual Labyrinth Puzzle's solution work?
 
 
First of all, both of the gaurds in the Liar-Truthteller solution don't necessarily have to answer your question. And even if the fact that they have to answer your question was implied, couldn't the liar just say that none of them lead out? {{unsigned ip|172.70.211.129|18:43, 16 February 2024}}
