https://en.wikipedia.org/wiki/The_Hardest_Logic_Puzzle_Ever
>Three gods A, B, and C are called, in no particular order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A, B, and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer all questions in their own language, in which the words for \emph{yes} and \emph{no} are \emph{da} and \emph{ja} in some order. You do not know which word means which.
>Boolos provides the following clarifications: a single god may be asked more than one question, questions are permitted to depend on the answers to earlier questions, and the nature of Random's response should be thought of as depending on the flip of a fair coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.
You should be able to solve this.

Does Random always speak truly or always speak falsely or is it random for every statement?

>> No.9392634

Can only be done with "If" statements I think, which trivialize these puzzles.

within an error margin of ±1 i have already found out which god is which, so the problem is immediately solved
what a stupid riddle lmoa

>Ask A: If I were to ask you, with you being in the state of mind you will have upon formulating an answer to this question, if B is True, would you say yes in your language?
>Ask A: If I were to ask you, with you being in the state of mind you will have upon formulating an answer to this question, if you are True, would you say yes in your language?
If A gives a different response to both questions:
>Ask A: Are you telling the truth?
If A does not give a different response to both questions:
>Ask A: If I were to ask you, with you being in the state of mind you will have upon formulating an answer to this question, if you are Random, would you say yes in your language?
This will give me all identities every time. The proof is left as an exercise for the reader.

Prove me wrong, brainlets.
