Sujiken is a number puzzle game that is similar to Sudoku, but with a twist.
The rules for Sujiken are simple, and are as follows:
- The goal is to fill all empty cells in the Sujiken board shown below.
- Place the digits from 1 to 9 so no digit is repeated within a horizontal row, vertical column, or diagonal in any direction.
- No digit is repeated within the three triangular regions and the three 3x3 square regions marked by thick borders.
- You can logically determine the solution without guessing.
- Each puzzle has only one solution.

Each column in the Sujiken board is denoted by a letter (A-I), and each row by a number (1-9).
After solving the puzzle, if you add up all the numbers in a given row (row 1, for example), you will get a number (Row1). Similarly, if you add up all the numbers in a given column (column D, for example), you will get a number (ColD). Do this computation for every row and column in your solution, and use those results in order to calculate the location of the cache according to the formulas below.
N 22° 2S.TUV
E 114° 0W.XYZ
S = Row4 - Row5
T = ColD - Row6
U = ColB - Row6
V = ColF - Row7
W = Row2 - ColD
X = ColH - Row8
Y = ColF - ColG
Z = Row3 - ColC
