This is one of my all time favourite puzzles …..
Imagine that you are a prisoner in a room. The room has two doors; one of the doors leads to instant freedom and the other to instant death.
Each door has a guard. One of the guards always tells the truth whilst the other always tells lies.
You do not know which door is which and you do not know which guard is which. There are no signs on the doors, no signs or names on the guards and no other visible clues to help you.
You are on;y allowed to ask one of the guards one question.
What question do you ask to ensure that you choose the door to freedom?
Have fun
