I'm a pinball wizard

As a kid in the 1970s.  My dad brought home a Bank a Ball Pinball machine.  The machine is as old as I am, I was born in 1965 as well.  I use to play that machine every chance I got, with friends and family.  I taught myself how to play pinball on that machine.  People would ask me how I learned how to play pinball so well.  I just told them, get a pinball machine of your own at home and practice, practice, practice.  The tilt mechanism is so sensitive, look at it wrong.  TILT!!!  So we had rules for playing the game, and not shaking the machine was one of them.  So when I watch people shaking a pinball machine like crazy and getting good scores.  I'd do the same, but not shake the machine.  Sometimes I'd get a very good high score too.  Then one night when I was playing the machine with family watching me.  I just started playing the first ball.  I shot it but instead of going across the top of the playing field.  It dribbled down the 10 slot and lit up the bumpers and the first ball got lodged between the bumper and the rubber band surrounding the free game housing or whatever you call it, for at least 30 mins or more.  I forget how long.  Let's just say, I finished the 5th and final ball with 4,720 points thanks to that lucky first shot.  I have never been able to recreate that shot since too.  I do love that there are no moving objects other than the flippers and the balls themselves.  And how small the flippers are compared to most modern pinball machines.  This is the only machine I've ever seen that has 5 actual playable balls in the machine.  And that you have manually load a ball in order to shoot it onto the field.  Plus you have to look down that little narrow slot at the bottom of the field to see what ball you're on.  Sadly, the machine needs some serious work to get it to work properly now.  It's been at least 30 years since anyone played it.  But we still own the same pinball machine my dad brought home.
