I help a friend of mine operate some pinball games in town and I've noticed people doing bang backs. I mean I can do them myself and do them from time to time. I don't want to start a conversation about whether or not people should be bang backing games on location so let's please just ignore that conversation.

What I want to know is if anyone has any techniques for making them more difficult. You can't bang back on all machines and it's very strange how only certain machines you can do it and others you can't. Even with machines that are of the same type, ie some fishtales bangbacks are super easy whereas I've played others and it's impossible.

What is the difference? Why does it work on one and not the other? How do I make them more difficult, so I can eliminate people using bang backs?

If biff bars are the bars behind the flippers those don't really work. I have no problem bang backing over those.

That's really just a good way to ensure nobody plays them. That's not the answer.
