The aim of a Sudoku puzzle is to fill the grid so that every
row, every column and every 3x3 box contains the numbers 1 to
9.
Once completed, use the values of squares A to G to decipher the
following final cache co-ordinates:
N 51º0A.0BC’
E 000º0D.EFG’
The cache can be approached from several different directions so
probably best to take a look at
a map and see which direction suits you the best. A small car
park can be found at N51°01.415', E0°02.201'E which provides access
to a reasonable track that will take you close to the cache.
