The Pinball Arcade does in fact have balls getting stuck. Mideval Madness in particular. Balls get stuck behind the ogres and sometimes up in the upper right area, just like the real thing. The ball can hit the glass if it goes over an ogre at the same moment the ogre pops, but it doesnt cause you to jump like the real thing. I cant say I have ever seen the ball jump the track or go off the rails.
The slight delay between pressing the button and a flipper flipping continues to be an issue.
