While nudging the machine is without a doubt part of the game if your tilting a game your doing it wrong. If you need to rock a game so hard it tilts for a ball save youve obviously already lost control of the ball and are unlikely to regain control after rattling the crap out of it. In the 20+ years ive been playing i probably dont even average a single tilt per year. I may only see a warning flash on a dmd screen once every 20 games or so. Since joining a league ive noticed its always the guys that consistently tilt that are at the bottom of the pack. I'll go out on a limb here and say if you are constantly tilting machines you probably SUCK at pinball.

The problem here is that you wasting your game time/life playing IM
