This research was  undertaken by Central Queensland University over two years.

The key research question that this study answers is: "Do jackpots and linked jackpots increase the likelihood of risky gambling behaviour and gambling related harm, and to what extent do jackpots enhance the player experience?" 

The researcher used two methodologies:

• lab-based experiments that simulated features of common types of jackpots; and
• an-invenue shadowing study whereby the researchers followed and recorded the play of volunteer EGM gamblers

The report found

1. EGM jackpots have a demonstrable influence on intensification of player behaviour
2. high level jackpot machines intensify betting behaviour and are differentially attractive to at risk players
3. little evidence for large differences in enjoyment based on the jackpot features of machines.
