- A [[gameplay-feature:ramps]] variant that physically changes position during gameplay, shifting the trajectory of the ball's path as the ramp moves. Unlike [[gameplay-feature:pop-up-ramps]], which rise and retract vertically, moving ramps reposition laterally or pivot to redirect the ball toward different playfield areas. [[manufacturer:williams]]' *[[title:fire]]* (1987) is the defining example, featuring three moving ramps that rotated on motorized mechanisms to create a constantly shifting playfield. The design eliminated [[gameplay-feature:pop-bumpers]] entirely, relying instead on the kinetic ramp assembly to generate chaos and spectacle — an unconventional layout that made the machine a memorable outlier.
