3 riddles

BACKGROUND: There are three ancient gods that look very similar to each other, live in a temple. One always tells the truth. One always tells the false. The other just tells randomly.

1. You ask the left god: Who is in the middle? He says: The true teller.

You ask the middle god: Who are you? He says: I’m the liar.

You ask the left god: Who is in the middle? He says: He tells everything randomly.

So who is who?

2. You are to ask only 3 yes/no questions to figure out who is who. The questions are in English, the answers are yes/no.

3. You are to ask only 3 yes/no questions to figure out who is who. The questions are in English, the answers are in their own language which contains only ja/da. And you do not know which words mean yes or no.

  • It could be that some god gets asked more than one question (and hence that some god is not asked any question at all).
  • What the second question is, and to which god it is put, may depend on the answer to the first question. (And of course similarly for the third question.)
  • Whether Random speaks truly or not should be thought of as depending on the flip of a coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.
  • Random will answer ‘da’ or ‘ja’ when asked any yes-no question.

The first riddle is a typical one that I learnt form my childhood. The third riddle is considered the hardest logic puzzle ever (source: wikipedia.org) The second is the one I simplify from the 3rd to learn and improve my logic skills.

Now, I’ve learnt how to overcome the random principle in the riddle. I think it’s great to share these riddles with you guys. Let’s tease your brain ^_^

  1. 1. the middle is the random because when you aks “who are you” if he is the true teller or the lair he will answer “I’m the true teller”. So the true teller and the god who said “the middle is the random, and the lair is the god who said “I’m the true teller”. In your quetion, i see two left god anh one middle god

  2. 2. You ask the middle “Are you standing between two god” If he said no, he is the lair, if he said yes, he can be the true or random
    You ask the left “Are you standing at the left of the middle god” if he said no, he is the lair, if he said yes, he can be the true or random and the lair is the right god
    After two questions, you can find out who is the lair
    You mark the middle god then ask the lair “is he the true” if he said no, the middle is the true, if he said yes, the middle is the random
