The cache is NOT at the posted coordinates.
In order to obtain the coordinates you must solve the Kakuro puzzle found in the gallery.
Rules for solving Kakuro puzzles:
• The number at the start of that run tells you the sum of the cells in that run.
• Only the digits 1 through 9 appear in the puzzle. 0 is never used.
• Inside each block, the digits will never repeat. For example, in a block with two squares,
and a target of 4 (what we would call a “4 in 2”) you will never see the digit 2, because in
the equation 2+2=4 there are two 2s.
The actual coordinates are:
N B10, B4° H1, G1.F9, G4, H6
W (I2-G1), H7, D5° J5, F4.E6, (D2-D2), F2
