It was the first pinball machine I ever played. It was 1984 and I was 9. I have no idea what the name of it was because to me back then, pinball machines were all the same and I was far more interested in video games. Well, there was a local Methodist minister that used to come in and play that machine and he was really good at it. He would rack up 10 free games and then leave and since they were free games; I would play. I actually got pretty good at it; though I never got the hang of the finer points of general pinball play like the nudges and bumps (without ever actually "tilting" it of course) and whatnot like the minister did. I got to a million once; which was the free credit point on that particular game.
Anyway, I only remember a few details about it, and one of the details I have only seen on that machine and no others since; so I'm hoping it is not a common feature that could apply to lots of pinball machines.
For starters it was a late 70's or very early 80's game with a relatively plain, flat playing field. It had 4 slots at the top with a light for each slot. If the ball passed through each slot and lit up all 4 lights, it was a good thing. I can't remember if you got a big bonus or what but I remember trying to do that.
Now, the feature that I remember most about it was that between and behind the flippers, was a little "cage" of sorts that, depending on what was going on in the game, could either let the ball pass through; ending your play for that ball as if it wasn't even there, or it could catch the ball and shoot it back up into play. Something like this:

Does this ring any bells for anyone?
