Two guards each watch a door. One of these doors leads to Paradise, and the other leads to Hell. We know that one of the guardians is always lying, while the other is only telling the truth. However, we do not know which guard is in front of which door. You want to go to heaven, and you have the right to only one question! Once the door is crossed, it is impossible to go back.

What question will you ask to be sure to find the right door?


Discover the solution of this riddle

To be sure of not making a mistake, just ask any guardian: "If I asked the other guardian to tell me the door of paradise, what would he answer me?" The two guards will then indicate the bad.

The guardian telling the truth will tell you the wrong door, because he knows the other guardian would lie on the issue. As for the liar, if you ask him the question, he will also indicate the door of Hell, knowing that the other one would have given you the right answer.

Then you have to take the other door, and you will be in Paradise!
