Attorney, Agent or FirmInternational ClassA63F 13/00 (20060101)AbstractApparatus for playing games on the cathode ray tube screen of a television receiver or monitor is disclosed comprising a viewer/participant game control box of conventional design and having components for providing location controllable symbols on the screen and a prerecorded source providing additional symbols on the screen. The output from the prerecorded source is decoded and applied to the game control box such that the game control box can operate on the symbols generated by the prerecorded source in a manner which it normally performs on internally generated symbols whereby the internally generated symbols and the prerecorded symbols interact to provide a game playing capability.Other References
