No need to fear breaking the game. You need to be the hulk high on PCP to actually break a game.

What you should do is practice being subtle and noticing how tiny nudges and bumps can alter the travel of the ball.

Every vibration you add to the cabinet will find its way to the ball.

Another way to think of it is this: Every surface is another potential flipper. A well timed and subtle nudge will affect the ball path and potentially give you a longer game.

You can even nudge and tap when the ball is already on your flippers. It’s often crucial for getting the ball to calm down.

Eventually you can work on more harder shakes and testing the limits of a games tilt sensor.
