Wow. never hurd of that... is that an add a ball game?

The 5 for 10c and 5 more for an additional 10c.
Rolf and Jr, you are both much wiser than I.
I started buyin my own pins because I did not want to lose so many quarters.
While I always restore a pin to factory function, I open the door, and flip the coin switch to add credits.
That being said, I only have one AAB, my Flipper fair. and one coin flick,"single player game", starts me off.
So I have not seen the 5 for 10, and 5 more for another 10c setting, or, at least, never paid attention to it. but it makes sense.
I never remember how many balls I have gone through, I just play till it says game over
Thanks for the operation clarification!
