To find the cache, begin by solving the following Sudoku puzzle. If you're unfamiliar with Sudoku or need a refresher, click here.
NOTE: This is NOT the normal Sudoku puzzle that you may be used to. Most Sudoku puzzles are a 9 x 9 grid, containing all 3 x 3 grids internally. This puzzle is different. The internal grids are irregularly shaped, and not always 3 x 3 square. The normal rules apply within these irregular grids, however.
Use the finished puzzle above and the "formula" below to solve for the actual cache coordinates. For example: (A3) = 4
N (A3)(G4) (A2)(B2).(C8)(G3)(E8)
W (C3)(I4 – F1)(G4) (E1)(F6).(B1)(D6)(E5)
