Let me give you an example that happens on my game.Nudge before you need to NUDGE.
A shot to the left ramp that rattles and doesn't make it will often come back down the ramp, hit the top of the left slingshot, loop over to the right and bügger off straight down the right outlane. Now when it does it I move the game ever so slightly to the left as it comes down so that it misses the slingshot. A potential hazardous situation avoided.
