To start with I put in the coordinates for the middle so (6,6). After this it gave me a number that showed how many squares I was away from the treasure. For instants 4, I would dot all of the possible solutions and then I would start with one of them. On that one it would give me another number, so I would get rid of all the other coordinates and put down the solutions. I would carry on doing this until I found the treasure.
