To work out the location of this cache, you need to do the following:
- Solve the puzzle below (see the cache listing for Slitherlink Boot Camp for the rules about how to solve Slitherlink puzzles).
- Write the letters A through to P in the empty squares (with A and B in the top row, C to F in the second, and so on).
- For each letter, its numeric value is the number of lines around the letter (which means each value is between 0 and 3).
The cache can be found at S 43 31.UVW E 172 33.XYZ, where:
U = G * B * O
V = F + M
W = B + P + O
X = D * (H + I)
Y = E + F
Z = G + A + J
The checksum for U to Z is 33.
The cache is a 200ml sistema in a black camo bag, It is tucked into a gap next to the corner post (please push it well back when replacing).
