Original Number Puzzle

  1. Nov 27, 2009 #1
    Using the numbers 1 - 17, place the numbers in the circles so that the sum of the numbers on every line equals 34. There are 11 lines. I have one solution. I think this is a very challenging puzzle that few can solve.

    As far as I can tell 10+2+12 in bottom line is not 34...

    Seems to me like there are just two solutions - symmetrical, so in a way there exist only one.

    14 - 16 4 8 6 - 3 1 - 13 11 - 5 17 12 - 7 2 - 10 9 15

    (these are rows)
