Accessories form category six. These include products that are used with games such as a rifle containing a photocell. The photocell detects the presence of light moving on the screen if the player's aim is accurate. As game clubs evolve, accessories especially prepared for club scoring, ultiple competition and other club use will become available.
Self-contained home TV games, category seven, are stand-alone units requiring no hookup to a standard television receiver. A backgammon game, planned by Allied Leisure, qualifies for this category. Home computers, category eight, are one type of stand-alone equipment.
Non-TV home electronic games fall into four categories: console, board, pocket and mobile. The console category includes home pinball machines; the board category covers games equivalent to board games such as Chess (which may also be implemented as self-contained TV games); pocket refers to small portable games such as Mattel's calculator-size football and racing games. The mobile category refers to games in which movement of three-dimensional objects takes place.
Electronic coin-operated games can be divided into three major categories: arcade games, cocktail table games and gambling equipment.
