Introduction
According to Wikipedia, the Japanese word "Masyu" means evil
influence. It is also the name of a type of logic puzzle that you
will need to complete to find this cache.
Masyu puzzles can be solved using just logic, no guessing is
needed to complete the puzzle.
The goal of a masyu puzzle is to draw a single continuous line
that passes through all of the black and white dots in the grid and
joins to its start to form a loop.
The rules are fairly simple:
- The loop must "enter" each cell it passes through from the
center of one of its four sides and "exit" from a different side.
All turns are therefore 90 degrees (vertical and horizontal lines
only - no diagonals).
- The loop must travel straight through the white circles, but it
must turn at 90 degrees in the previous and/or next cell in its
path.
- The loop must turn at 90 degrees in black circles, but cannot
turn in the cells immediately before and after the cell.
- There must be only one unbroken loop that does not cross
itself.

The hiding place is very easy to spot from the track (which is a
bit like a masyu puzzle in itself), so please hide the cache well
when leaving.
