River Crossing Puzzle

A bomb disposal technician, a suspicious bag, a soldier, two security dogs, a suicide bomber, his wife in wheelchair and his daughter have to cross a river. They have discovered a small boat. The small boat can carry only two people or one person and one dog or item at a time. The suspicious bag can not be left with anybody unless the bomb disposal technician is present. The suicide bomber can not be left with any of the dogs unless the soldier is present. The soldier can not be left with any of the suicide bomber’s family members unless the suicide bomber is present. Only the soldier, suicide bomber, and bomb disposal technician know how to use the boat. How would they cross the river?

  • love this

  • jess

    can the dogs swim across the river?

  • lapetitefaon

    OH MY GOODNESS! What a cool idea!

  • currently shown in the GFZK (Leipzig, Germany)
    been there last weekend.

  • This is groundbreaking stuff. An old puzzle taken to a different medium in a very innovative way. Very cool.

  • slashinkev

    Awesome! But is this even possible?

  • Vincenzo Michaelangelo

    The suicide bomber brings his family, then the soldier brings the suicide bomber, the bomb technician then brings the soldier, then the dogs, one by one, and finally the suspicious package.

    • im not sure this is taking into account who is left on the other side when the person is travelling back with the boat

  • Vincenzo Michaelangelo

    yeah it is, the suicide bomber is never with the dogs without the soldier, the soldier is never with the famliy without the bomber, and the suspicious package is always either with the bomb technician, dogs (not a person) or by itself.

  • Vincenzo Michaelangelo

    ok you were right, the bomber first has to take the soldier across, then go back get his wife, bring the soldier back, then bring his daughter over, then the sequence I said before can happen without breaking any rules

    • yea i think that’s it! haha well done

    legend:

    A = will ride the boat to cross
    B = to be left behind on the other side
    C = will ride the boat to go back
    BT=BOmbtech

    S=Soldier
    D1=dog 1
    D2=Dog2
    SB=Suicide Bomber
    WC=wheelchair
    W=Wife
    K=Kid

    • …. did you figure this out using math?

  • hannah

    i am actually unsure if you guys were able to understand my answer but no i didnt figure this out using math.. just thinking only…

    i rephrased my answer, and here it is:
    first to ride the boat are the BT and the B, B will be left behind and BT will go back to fetch others
    next to ride are the BT and S, BT will be left behind and S will go back to fetch others
    next to ride are the S and SB, SB will be left behind and S will go back to fetch others
    next to ride are the S and D1, D1 will be left behind and S and SB will go back to fetch others
    next to ride are the S and D2, D2 will be left behind and S will go back to fetch others
    next to ride are the S and SB, S will be left behind and SB will go back to fetch others
    next to ride are the SB and WC, WC will be left behind and SB will go back to fetch others
    next to ride are the SB and W, W will be left behind and SB and S will go back to fetch others
    next to ride are the SB and K, K will be left behind and SB will go back to fetch others
    next to ride are the SB and S

    • no i understand it, i am amazed – i believe there is a way to solve the puzzle mathmatically as well
