Abstract
A pinball machine having a vertically displaceable ramp play feature. The ramp moves between an upper position in which it does not interfere with gameplay, and a lower position in which the lower edge of the ramp rests on the playfield. When the ramp is in the lower position, balls can be directed up the ramp towards a suitable target, such as a raised playfield.
