3 Squares Cipher uses combination of triangles and dots to encrypt the message. The orientation of the triangle and the placement of the dot is specific for each letter.
Theoretically, each letter could be randomly allocated, which would result in a rather difficult to solve cipher. To make deciphering easier, here are the rules.
Letter “a” must be placed in 1 of 12 white corners and from there, moving in one direction only, filling the white corners first, complete the rest of the alphabet, as depicted in an example below.

Cache is not at the listed coordinates but close by. Looking for a small official geocache container that only has logbook and pencil in it for now.
