Impossible number grids giving me grey hairs!
A challenge for you all: This is the third forum I'm trying, and thus far the squares below remain unsolved. It is my hope that this forum will change that!
Attached are two number grids. One is a 10X10 and and contains numbers 0-9. The other is a 12X12 and contains number 1-12. The squares come from different puzzles, but by the same author (I included both as one square is complete, and may give a clue as to how the other is compiled)
The puzzles both bare no copyright, and form part of a geocaching puzzle (see Geocaching - The Official Global GPS Cache Hunt Site).
By filling in the numbers on the 10X10 square one should be able to obtain a set of GPS coordinates. As we are in Cape Town, South Africa, the numbers will probably look like this: (S33[or 34] XX.XXX ; E18 XX.XXX)
The 12X12 square puzzle came with the following clue which would also reveal a GPS coordinate as for the above:
S 34° [9(1) - 9(2)] [7(4)] . [2(2)] [6(2)] [7(3)]
E 018° [6(1)] [4(2)] . [4(1)] [9(4)] [1(4)]
Wishing you all the best and may thanks ;)
