Abstract
Abstract A dart game assembly comprising a housing element, a spider, a plurality of target plates and a back plate. The spider is generally circular in shape and comprises a series of circumferentially and radially extending ribs integrally molded with the housing element from a single piece of material. The circumferentially and radially extending ribs form interiorly spaced cavities that are adapted to receive the plurality of target plates. Each of the plurality of target plates comprises several target segments which are interconnected and capable of independent movement upon being impacted by a dart. The back plate is integrally molded from a single piece of material and is attached to the housing element.
