Newbie here who inherited a pachinko machine that the previous owner left behind. It was working just fine until last year when the balls stopped launching. I suspect my little 3 year-old niece might have snuck something into the machine that's blocking the balls from loading into the shooting area.
I don't really know how I can open it up to check the ball paths so I was hoping someone here would be able to help me. The case that the pachinko machine is in looks just like the one in this user's post:

Any help would be appreciated. I'd love to be able to fix it so the kids could play with it again.
