Riddles have roots that run deep into the literary tradition of the West. There is a book called the Exeter Book. It is the largest collection of old English writings. It contains rhymes, puns, and compound words that are used as metaphors in place of single words, or riddles that are in the form of kennings. For example, “the sea” means “whale-rod”.

There are famous riddles that demonstrate a protagonist’s wit in a story or let a character escape some dire situation by using their brains rather than brawn. There are some riddles that play the role of reminding people that there are some questions which cannot be answered. While these can cause unending frustration and head-scratching, the unanswerable questions in the form of riddles make the most strange but pleasant riddles of all.

The Hardest Logic Puzzle Ever from George Boolos

This riddle is more of a riff of the earlier mentioned "heaven-hell" riddle. It was by George Boolos, but it was inspired by Raymond Smullyan.

Riddle: There is an Island that has 3 gods. One god always tells a lie, and the other always tells the truth. The third god has a random behavior. To top it off, these three gods, being jerks, answer in their own languages such that you are unable to tell which word, between “ja” or “da”, means “no” or “yes”. You have 3 questions to work out the True god, the false god, and the Random god.


Question 1: (To any of the three gods) If I were to ask you "Is that the random god," would your answer be "ja?" (This questions, no matter the answer, will enable you to tell which god is not random i.e. the god who is either False or True)

Question 2: (To either the True or False god) If I asked you "are you false," would your answer be "ja?" 

Question 3: (To the same god you asked the second question) If I asked you "whether the first god I spoke to is random," would your answer be "ja?"
