Riddle statement

Three gods, A, B and C, are called Truth, Falsehood and Random, in some order.

  • Truth always answers with the truth.
  • Falsehood always responds with a lie.
  • Random answers at random.

They understand your language, but they answer using the words “da” and “ja”, and you don't know which means “yes” and which means “no”.

You can ask exactly three questions, each directed at a single god and with a yes/no answer.

How do you identify with certainty which is which?
