A GAME FOR SLOT MACHINES WITH A ROTATING DEVICE TO SIMULATE REMOVING A NUMBERED BALL FROM A SPHERICAL DRUM

摘要

In the event of the player not having obtained a prize in the basic game, a window and button or suitable projection, will indicate the possibility of seeking a prize in a complementary game of chance, which consists of a lottery whose numbered balls are removed from a rotating drum device. A prize ball, once removed, will be visualised in the top window which indicates numerically the consolation prize obtained, which will then fall into a tray. The drum consists of a spherical cage resting and turning on a horizontal axis on two vertical panels of a basic slot machine and moved by a suitable motor. This cage, at an equatorial point, perpendicular to the spin axis, includes a coupling whose inlet coincides with an outlet orifice for the balls contained in the spherical cage. A transparent tube is connected to the coupling and is closed at its free end by a lid of fitted opercule while in the coupling and closing the outlet. There is a flap at right angles with different branches, one longer than the other to retain or take only one ball from those contained in the cage, on making turns of 90 degrees.
