Examples of patterns

Each of the 1's inside the nine grids, has a position within the grid.

So you mark those positions as dots on your criss-cross pattern.

Begin with the first grid in the upper left, and end, on the ninth grid at the lower right of the puzzle. The resulting pattern is this.

(you will always have a total of 9 dots to work with)

In this example we will use the number 1

notice how the second time a dot a applied, it is actually a circle around the first dot

The next pattern will be performed by using the number 6

I call this one the bomb, notice the third instance of a dot, it becomes a large black circle

Next is example A:

Using the number 4
