Just follow the instructions for the first shot, and you should end up near the wall.
The Red arc, is where you can shoot with full power and it will tunnel, however im yet to find a shot that goes through to the hole section or even go in the hole.
so im posting it, as the old saying goes, many hands make light work
I used to have a shot that used this tunnel but different first shot, but I deleted my golf folder with like tonnes of shot when I stoped, wish i didn't!
I think this first shot is fooked, its just not happening
Oh well,at least some of you guys have made it at one time,not me,i've been trying that shot for a while but everytime it hits the tunnel it bounces back up and end up near upper part of the bench
