Tilt

A tilt in pinball game play is when a player has moved the machine enough to cause the game to stop play.  In modern pinball machines the player is usually allowed two dangers before a tilt ends their ball.  Older pinball machines had differing rules about what the recourse is for a tilt.  Some machines would just end the ball and others would even end the player’s whole game.  The machine normally determines when a danger and tilt happen by the use of the plumb bob mechanism.
