ABSTRACT:
A section of the play field is changed during play by replacing components mounted thereon with different components. In other words, the section of the play field is replaced with a new section. Preferably this is done by rotating the section of the play field to expose different components that were previously stored below the play field surface. In a preferred embodiment the section of the play field is coupled by a slip clutch to a continuously running motor, and a solenoid operated catch mechanism stops rotation of the section of the play field when it is approximately parallel to the rest of the play field surface. To change the components included in the play field, the solenoid is energized to release the catch and thereby permit rotation of the section of the play field by approximately 180 degrees.
