Quoted from TigerSaw:I feel like I am asking "How do I walk?" and you are all going "Back in 1818 shoes were invented. Shoes are really great .... sometimes shoes happen" ... lol which is neat, but not helpful at all.
I think the confusion in this thread stems from terminology. I think what you're call "tilting" is properly called "nudging".
Nudging (or other more specific terms for specific kinds of nudging/shaking/etc) refers to ways of shaking, nudging, whacking, or otherwise applying force to the machine to change the course of the ball.
A "Tilt" is the penalty applied if you nudge the machine too hard and trigger the tilt sensor.
So people think you're asking how to trigger the tilt sensor on a pinball machine (which is easy, just shove it until it tilts)
How to nudge?
The general tricks are:
Slap save - when a ball is heading towards the center drain just a little too far for the flipper to reach it, you hit the closest flipper while nudging it, and then immediately do the same in the other direction with the other flipper, the hope being that the nudge brings the tip of the flipper into contact with the ball while you're flipping - this will likely send it toward the very tip (or just beyond the tip) of the other flipper, so you do the same thing to try to catch it with the tip of the other flipper, hopefully keeping the game in play.
Shaking - give the game a gentle upward shake when the ball is in a set of bumpers to get more action. More useful on some machines that others.
Bangbacks/deathsaves - wizard technique for getting a ball that goes down the outlanes to jump back up onto the flippers. I can't pull this off, but if you've ever seen those little bars on the playfield right under the flippers - they're there to prevent deathsaves and bangbacks.
Also there are game-specific reasons to nudge, you might find that the ball in a certain area tends to drain, but find that you can give it a nudge at the right time to divert the ball on a more desirable course. On my TZ, a slow, gentle roll along the two greed targets to the left of the slot machine is a certain drain, but a nudge to the left will ensure that it instead hits the left flipper.
How hard to nudge? Hard enough to achieve your goal, but not so hard that you get a "TILT" and get the ball ended. On machines that don't have working tilt sensors, just respect the machine and avoid damaging it.
