The final coordinates are not at the posted location.
To solve this puzzle, you must follow four rules:
1. The grey cells must include all integers between 16 and -16, EXCEPT zero.
2. No number can be repeated within any of of the grey cells.
3. No number can be repeated within any of the white cells.
4. The number in each white cell must equal the sum of its adjoining half-height cells. The inside four squares must add up to zero.
**You CAN resuse numbers between the white and grey cells - so even if you've used a 1 in a grey cell, you CAN use a 1 in a white cell. There just cannot be any repeated numbers within cells of the same color.
NOTE: There are five boxes outlined with a thicker border. Once you complete the puzzle, add these five numbers together, and SPELL OUT the result - this is what you should put into the certitude checker to get the final coordinates!!
