Scratch-cards are less strongly associated with problem gambling, since it is less continuous than slot machines, has a slower event frequency, & near-miss design features are unlikely to have a significant impact upon behaviour

Empirical Evidence Relating to the Relative Riskiness of Scratch-Card Gambling. Paul Delfabbro & Jonathan Parke. Journal of Gambling Studies, May 10 2021. https://rd.springer.com/article/10.1007/s10899-021-10033-2

Abstract: Scratch cards (SCs) or tickets are lottery-based games which are played by scratching to reveal numbers, letters or symbols to win prizes. Such activities have sometimes been likened to paper-based slot-machines, but relatively little systematic analyses have been conducted to examine the risk or harm associated with these activities. In this paper, we provide a narrative review of the peer-reviewed literature relating to the potential association between SCs and problem gambling and what is known from publically available data sources (e.g., prevalence studies and treatment data). Evidence is analysed within the context of the Bradford Hill Criteria. Both prevalence and peer reviewed literature suggest that SCs are less strongly associated with problem gambling than most other gambling activities. We argue that this difference is due to the nature of the products. SC gambling differs from slot-machine gambling in a number of structural ways; it is less continuous; has a slower event frequency; and, emerging literature suggests that near-miss design features are unlikely to have a significant impact upon behaviour. Thus, in our view, and based on the empirical evidence, it appears that earlier parallels between SCs and slot-machines now appear more tenuous. Nevertheless, we encourage further investigation into the potential impact of new and emerging online lottery products because of the more immersive, faster and more technology-based nature of these products.
