Abstract
A gaming machine of the kind in which a combination of symbols is selected at random by spinning and stopping each of a set of coaxial reels, each reel carrying a plurality of symbols around its periphery and serving to display at least one of these symbols in a display window when stationary, characterized in that the reels are spun by a drive mechanism comprising a lever operated mechanism through which the work done by a player in operating a lever is transferred to the reels so as to spin them, and electrical powered drive means including a motor driven shaft on which the reels are rotatably mounted and to which they are frictionally coupled through individual slipping clutches. Preferably, the lever, when operated by a player, triggers operation of the electrical powered drive means so that the reels are spun by both the lever operated mechanism and the electrical powered drive means. Operation of the electrical powered drive means may also be controlled by one or more player operated devices separate from said lever, whereby a player can spin one or more of the reels.
