It would be way easier to show you, but I don't have any easy way to do that, so I'll try my best to explain it...
The game is ALL about drop catch control, bounce passes and waiting patiently to know when to flip. The way that the, uh, bowl (playfield) is set up, you need to figure out what balls will safely bounce off one flipper to the other, and how to arrange those flippers so that you can best get the ball under control. You need to do a lot of adjusting to how differently things pass, and with the bowl set up like it is, you can do otherwise totally impossible passes like passing it over the right flipper, flipping the right flipper up and holding it so the ball goes back underneath it and settles on top of the left flipper.
It's a trip, but I guarantee you that it can be done. I can relatively consistently hit things on my machine when I've put a few games on it to get used to it, but then like I said if I go back to anything else, it takes a few games before I feel like I have any of my skills back.
Oh yeah, and the shots are really interesting too, because you have to figure out how to bank them on a non-flat surface around those spinning bumpers and into the drop targets in the back. Again, it takes a while to figure out where to actually aim your shot to get the result you want. It takes a lot of trial and error, but you can actually get there.
There is a definite luck factor with Orbitor that I won't deny at all, but you can definitely figure it out and gain control of it when you play it enough.
