How electronic gambling machines work

The purpose of this paper is to provide policy makers, regulators and others with information about key design characteristics of electronic gambling machines (EGMs). These characteristics include auditory and visual cues, “game maths”, and price and prize structure. They also include elements in the games that render them attractive to EGM users, and which appear to be associated with the establishment of persistent game utilisation or addiction. It is hoped that a better understanding of these characteristics will help policy makers and regulators to frame policies and interventions that will reduce harm to gamblers from EGM use.
