    A little brain-teasing riddle for everyone

    A riddle:

    Two men are in a room that has 3 doors. The men are sitting on the floor opposite 2 of the doors. Both of these doors can be opened from inside the room, and both men know this. The third door is on one of the side walls perpendicular to the wall with the 2 doors, and it can only be opened from outside the room, and both men know this.

    One of the men is a liar. He lies about everything. Everything he says is a lie.
    The other man always tells the truth, no matter what. Everything he says is absolute truth.
    They know that about each other.

    One of the two doors leads to instant death if you open it. The other door leads to your freedom when you open it. Both men know which door is which. Both men know that each of them know that.

    A third man enters the room through the third door.

    He knows that one man is an absolute liar, and that the other always tells the truth. He does not know which is which, but he does know that they know that about each other, and that they know which is the liar and which tells the truth.

    He knows that one of the two remaining doors leads to death, and the other leads to freedom, but he has no idea which is which. He does know that both men know which door is which, and that they know that each of them knows the correct information.

    The man wants to leave the room. He cannot return through the door through which he entered the room, but must leave through one of the other two doors. Obviously, he does not want to die.

    He is allowed to ask only one of the men a single question.

    What SINGLE question can he ask of either man to guarantee his freedom?

    Remember .......he does not know which man is the liar, and which tells the truth.

    The first to solve the riddle will receive the spurious and ersatz title of "Master Riddle Solver".


    -Be kind. That is something you will never regret. You will never say to yourself when you are old "I wish I was not good to that person".

    Ask one which door the other guy would tell you to go through and do the opposite.

    Credit to 3True:

    Stand in front of one door, and ask one of them, "Will he [pointing to the other guy] tell me that I will live if I go through this door?"

    If answer is NO, go through that door. If answer is YES, go through other door.

    No pointing. You are close...but again be more specific.

    OK......this answer is close enough.....it would work. Guess I should have included that something like they could not answer yes or no questions. Oh well.

    The "official" answer is " Which door will the othe guy say is the door to freedom?" Both of course will point to the door to death, so the man takes the opposite one.

    You could ask, "what would the other man say if I asked him where this door leads?" The opposite is then true.

    I guess there isn't many people that remember the Labyrinth on now.
