The auxilliary game includes a cage carrying numbered lottery balls arranged to rotate and to release a ball into a transparent tube. A simulation of the ball number is arranged by electronic control to show in a window thereby to indicate a consolation prize. Ball release is controlled by a ball escapement mounted at a ball outlet of the cage and operable to release only a single ball from the cage into the tube at one time and to return the ball to the cage during progressive rotation of the cage.
