You meet three gods: True (who always tells the truth), False (who always lies), and Random (who randomly chooses whether to tell the truth or a lie). They speak a language where "da" and "ja" mean "yes" and "no," though you don't know which is which. You are allowed to ask three yes-no questions to any of the gods (you can direct multiple questions to the same god). How do you figure out their identities?

The strategy requires asking a first question that forces a compound statement, neutralizing the Random god or identifying a safe truth-teller/liar first.
