Abstract: The present invention provides a feature game facility operated purely at a system level in a linked system of EGMs. The feature game controller operates common features in such a way that each EGM is ‘unaware’ of the feature being played. EGMs 11 include a secondary display 12, in addition to the main EGM display 17 linked to a common site controller 13 via a communications network or link 14 and a common uni-directional communications protocol. The site controller 13 is responsible for operating and monitoring the feature games, and the display of the outcome is downloaded from the site controller 13 to the secondary displays 12 within the applicable EGMs II on the link 14.
