Geocache Description:

A geo-sudoku puzzle hide.

Don't go to the posted coordinates, the cache isn't there. Mrs. Sardonicus came up with this idea and left it to Mr. to figure out how to implement the puzzle. She did the checking and pronounces this to be a 1, to at most, a 2 star sudoku. Number place puzzles (sudoku) were invented by an Indianapolis Architect, Howard Garns. Wikipedia has a nice little bio about him as well as instructions for the game (if you not familiar with the rules) The game involves logic but no math. Because of the constraints of the puzzle and map coordinates there will be some simple subtraction to do after you solve the puzzle. Solve this Number Place:

then use the answer from the grid to get the coordinate numbers in this format: North: a1 a2 a3 a4. a5 a6 a7 West: d1 d2 d3 d4. d7 d8 d9 Now do some subtraction to get the final answer: subtract 16 from a5 a6 a7 subtract 30 from d3 d4
