Geocache Description:


This cache is part of a series that requires you to find mystery caches by first solving five Trexagon puzzles of varying difficulty. Each of the five puzzle solutions contains the coordinates for a cache, and taped on the cache container and log sheet for this cache is part of a final "Killer" Trexagon puzzle, whose solution leads to a sixth cache. A blank Trexagon board can be downloaded here. A clue for the sixth cache is taped on the container and the log sheet for this cache.

If you are new to Trexagon, starting with the Easy one might be best.

The rules for Trexagon are simple, and are as follows:

  1. The goal is to fill all triangle cells in the Trexagon board shown below.
  2. Place a digit from 1 to 7 in each triangle so no digit is repeated within a horizontal row or any diagonal in any direction.
  3. The inner shaded triangle does not contain a digit.
  4. Each puzzle has only one solution.
  5. The board contains several zones, that is, triangle groupings marked by heavy borders. Each zone has a desired value and an operator + , − , × , ÷ . The digits in each zone will produce the desired value using the given operator.
  6. When a zone contains just a single triangle, then the identified digit can simply be inserted.

Each row in the Trexagon board is denoted by a letter (A-D) from top to bottom. Each triangle within a row is numbered from left to right starting at 1. So, A1 is the left-most triangle in the top row. Use the values in your solution to calculate the location of the cache according to the formulas below.

S 43 31.STU
E 172 35.XYZ

S = A6 - C1
T = B4 - C2
U = A7 - B2

X = A2 + B5
Y = D1 + D2
Z = A4 + B3
