    Japanese Brain Teaser

    This was passed through my office. It is easy once you figure it out, but can be very frustrating to some. It took one guy in our office over an hour. On the other hand, my 8 year old figured it out in about 10 min. The rules and instuctions are below, because they are in Japanese on the web site.

    Good luck

    The rules are:

    Click on link then click on blue circle. Use the rules below.

    This is going to do your head in, but it can be done. I've worked it
    out.

    For those of you who are not going to even understand the rules (you
    know
    who you are) get someone to explain them to you.


    Apparently this is an IQ test given to job applicants in Japan:
    "Everybody
    has to cross the river".

    The following rules apply:

    Only 2 persons on the raft at a time

    The father can not stay with any of the daughters without their mother's
    presence

    The mother can not stay with any of the sons without their father's
    presence

    The thief (striped shirt) can not stay with any family member if the
    Policeman is not there

    Only the Father, the Mother and the Policeman know how to operate the
    raft

    To start click on the big blue circle on the right.

    To move the people click on them. To move the raft click on the pole on
    the
    opposite side of the river.

    Appears you about aced that Ben

    Might have been this one or a similar deal - where best way to rationalize things was to ascribe algebraic variables to each person and build an equation or two.

    I'll have to try that one later, We did a simular one in school with a Fox, chicken, and some other animals. Same rules sounds like. It was a toughy, I agree with Chris, have to find some good concentration / quite time.

    Nice one! I heard one quite similar involving a party of 3 missionaries and 3 cannibals. There is one boat available to cross the river which only holds 3. Get all of them across following this rule: on either bank or in the boat, cannibals must never outnumber missionaries because if that occurred, the cannibals would eat.
