The cache is NOT at the posted coordinates. You will need to sovle the puzzle to get: N49 38.ABC and W112 49.DEF where;
A=C5 - B=E4 - C=G3 - D=I1 - E=A2 - F=D7
There are a lot of Sudoku puzzle caches out there and we felt that Lethbridge needs one. “J” loves doing them – “D” not so much, so you know who to blame for this one!
Sudoku is fun and this one is particularly easy to do. There is no math involved – just reasoning and logic. Fill in the grid so that every row, column, and every 3x3 box contains the digits 1 through 9.
Good Luck!
