This cache is part of a series that requires you to find mystery caches by first solving five Sujiken puzzles of varying difficulty. Each of the five puzzle solutions contains the coordinates for a cache, and placed in each physical cache container is part of a final "Killer" Sujiken puzzle, whose solution leads to a sixth cache. A blank Sujiken board can be downloaded here. The clue for the sixth cache is taped both to the cache container, as well as to the front of the log book, in this cache.
If you are new to Sujiken, you might want to start with the easiest cache in this series.
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.
S 43 3S.TUV
E 172 3W.XYZ
S = Row4 - ColD
T = Row5 - ColF
U = ColF - Row6
V = ColF - Row7
W = Row1 - ColB
X = ColE - ColG
Y = Row2 - ColC
Z = Row5 - ColE
Notes on the Cache Sites:
- At times this may be a high muggle area.
- Please replace the cache where you found it, and attempt to keep it hidden from sight.
Congrats (again) do dan.reilly for the quick FTF (about 60 minutes)!
