We've all had to puzzle out various co-ordinates before so this should be easy for you! All you've got to do is solve an easy-level sudoku puzzle in order to find the co-ordinates for the actual cache.
A sudoku puzzle is a grid of nine by nine squares or cells, that has been subdivided into nine subgrids or "regions" of three by three cells.
The objective of sudoku is to enter a digit from 1 through 9 in each cell, in such a way that:
- Each horizontal row contains each digit exactly once
- Each vertical column contains each digit exactly once
- Each subgrid or region contains each digit exactly once
In each sudoku puzzle, several digits have already been entered (the "givens"); these may not be changed.
The puzzler's job is to fill the remainder of the grid with digits –respecting, of course, the three constraints mentioned earlier.
Inside the grid, you'll also find some letters. When you've correctly solved the sudoku puzzle, the letters will correspond to the co-ordinates for the cache location in this way:
N 46° AB.CDE W 84° FG.HJK
