The grid is a rectangular pattern of dots or lines that extends over the area you specify as the grid limits. The grid displays dots only when the current visual style is set to 2D.
A grid search is based upon the amount of area to be searched, and how much area a searcher can see at one time. The grid is divided up into squares as wide as the searcher's capability, and as the searcher(s) move forward, each grid square is scanned. At the end of the row, the searcher(s) move over to the next row, and repeat the search in each grid square.
If both points have either the same 'x' value or the same 'y' value, then they both lie on the same grid line.
Counting squares whose sides are along the grid-lines, there are 154.
