Abstract
A game apparatus includes a viewing device which incorporates a viewing console that receives replaceable visual cartridges and a microcomputer for generating game functions. The visual cartridges are automatically opened upon insertion into the viewing console to reveal a three-dimensional scene. When the visual cartridge is opened, its cover swings into alignment with a plurality of light emitting elements. These elements are operative to selectively illuminate various regions of the cover and to project indicia located on the illuminated region onto the scene provided by the viewing cartridge. Each viewing device can be provided with a plurality of different cartridges with covers bearing different symbols to produce a variety of visual effects useful in implementing game devices, particularly microcomputer controlled game devices, and visual displays such as advertising displays and the like.
