ONE MORE IMPORTANT THING I FORGOT TO STATE: you must also say numbers on where your going to hit, so for example:

OOOOOOOOOO

OOOOOOOOOO

OOOOOOOOOO

OOOOOOOOOO

So, if I’m gonna hit bottom left corner, I say 4-1. If I wanna hit top left, 1-1. Just count how far your going horizontally, max is 10, and max for vertical is 4.
