Today, I share some Magic Dance, courtesy of Labyrinth and David Bowie, while I puzzle you with riddles.
Knights and Knaves is a logic puzzle created by Raymond Smullyan. It is based on the idea that you are a visitor on a fantastic island inhabited entirely by two groups of people – knights who never lie, and knaves who never tell the truth, and your job is to figure out who is who.
Riddles like these are something I loved growing up. I got 2 of the following 3 questions right, I thought it would be fun to see how my readers fared..
Up for the challenge?
Here is the scenario:
John and Bill are residents of the island of knights and knaves.
Question 1
John says: We are both knaves.
Who is what?
Question 2
John: If Bill is a knave then I am a knave.
Bill: We are of different kinds.
Who is who?
Question 3
John and Bill are standing at a fork in the road. You know that one of them is a knight and the other a knave, but you don’t know which. You also know that one road leads to Death, and the other leads to Freedom. By asking one yes/no question, can you determine the road to Freedom?
**
Readers who have watched the film Labyrinth have a distinct advantage with that last question.
I answered the first 2 very quickly, and while my logic seemed ok with the 3rd question, it wasn’t the right answer.
Be brave, and comment your answers!
