Abstract
The invention relates to a play feature for a pinball game able to assume a plurality of scoring positions. Various embodiments are disclosed, including two-position targets and four-position targets. The devices are actuated by a solenoid which cooperates with a cam to provide linear or rotary output to change the target position. The solenoids are actuated by a switch associated with the targets. The positions of the targets are sensed to provide different scoring values for each of the different positions.
