This study includes a literature review of the relationship between gaming machines and problem gambling and a survey assessing Key Informant's ideas an opinions about this relationship and measures to mitigate it. The literature review assessed which features of machines and their environment had been implicated in problem development, and separated three groups: features of machines, venue features and community accessibility. The survey questionned Key Informants using questionnaire and focus groups. In a broad sense, Key Informants believed that certain features intrinsic to EGMs, such as the speed of play and appearance of near-misses, contribute to the risk of problem gambling. With respect to potential modifications, all Key Informant groups supported changes that did not directly involve the functioning of EGMs, but focused instead on the management of money, pre-commitment, the use of smart card technology, and restricting community access.
