The Victorian Responsible Gambling Foundation engaged CQU’s Experimental Gambling Research Laboratory to investigate how different environmental contexts of Electronic Gaming Machines (EGMs) influence gambling consumption and harm. The aim of the project was to systematically investigate the environmental context of online, mobile and venue-based EGM gambling to determine what combinations of environmental and contextual features are most associated with problem gambling, and also to determine what environments are attractive to players who gamble recreationally and without apparent problems. This information will help policy makers and operators to devise and encourage gambling environments that are safer and more enjoyable for players.
