A feature of most modern
pinball machines. Ramps generally require a skillful shot, since you not only need to hit them fairly straight-on, but also with enough
momentum to get the ball up the ramp. Because of this, ramps are often used as targets for high point awards.
Some ramps are easier to hit than others because they have a wider mouth that gradually narrows down to guide the ball into a narrow path, or because they aren't so steep, or because their placement makes them easier to hit. Be careful of weak ramp shots; some games don't have any sort of diverter to slow down or redirect balls that don't make it all the way up the ramp, and sometimes these balls come screaming back down toward the flippers.
Some games just have one simple ramp, while others have multiple ramps that travel in complicated patterns all over the playfield.
