Gary - let's see if I can explain it, because I sure can't draw it.

Let's give the dots numbers:

123
456
789

1.Draw a line that goes from 1, passes through 5 and stops at 9
2.Draw line from 9 up through 6 and through and PAST 3
3. Draw line from above 3 that goes through 2 and through and PAST 4.
4. Draw line from past 4 through 7 and 8 back to 9.

You have lines that look like an arrow pointing to the lower right hand corner.
