    - There are 3 boxes
    - Only one of them contains gold
    - Every box has a message written on it and only one message is true.
    - On box 1 is written: "This box is empty"
    - On box 2 is written: "Box 3 contains the gold"
    - On box 3 is written: "The other boxes are empty"

    Which box contains the gold?

    The message on both box 2 and 3 say that box 3 contains the gold, they both can't be write so box 3 doesn't contain the gold.

    Box 1's message must be true because the other two are false. This means that box 1 doesn't contain gold, neither does box 3.
    Thus box 2 must contain the gold.

    It could be box 3, if box one contains a rock or something.

    Or it could be box 2. There's not enough information to tell which.

    That's true. I think you have to assume that each box can only contain either gold or nothing at all, in which case the labels point to box 2 as containing the gold.

    Nope. You would have needed to tell us that the boxes not containing gold were empty for this problem to be solvable

    I agree. This problem has several loop-holes.

    If there is a rock in box 1 and the gold is in box 3, how many messages are true?

    If only one message is true then box 2 has the gold, and the true mesage is the message on box 1.

    It has to be 2:
    Box 3 has to be empty, because only one message is true, and both 2 and 3 say that it is in 3. Both must be lying. That leaves 1, and it says that 1 is empty. So, you know 1 tells the truth about being empty, and that it is not in 3, so it must be 2.

    Read carefully:
    box 1 contains a ROCK, this has not been excluded by the original question.
    Box 3 Contains the GOLD

    On box 1 is written: "This box is empty" FALSE - There is a rock in it
    On box 2 is written: "Box 3 contains the gold" TRUE - It does
    On box 3 is written: "The other boxes are empty" FALSE - There is a rock in box one

    Hence 1 true statement, therefore box 3 could contain the gold.

    Sorry about the Caps, getting a bit too excited.
