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.

Key messages

Electronic gambling machines (EGMs) are computers utilising sophisticated techniques, designed to maximise spending and “time on device” per user.

EGM designs very successfully employ psychological principals to maximise users’ bet sizes and machine usage. These characteristics have the effect of increasing the addictive potential of EGMs.

Users of EGMs, and policy makers as well, are mostly not well informed about the way the machines work, or the complex “game maths” behind them.

Internationally, Australian EGMs are known for their ability to maximise users’ spending and “time on device”, yet Australia has been slow to develop adequate policy responses to reduce harms.

His interest is in the relationship between poker machine gambling and socio-economic disadvantage and health inequity, and in the development and implementation of relevant harm minimisation policies and strategies. He has also researched the structural characteristics of poker machines and the relationship of these, and the structure of gambling systems, to the development of gambling problems. His current research is focused on mechanisms of gambling industry influence in relation to public policy, and on regulatory issues around development of best practice gambling policy.
