“…Throughout the study, participants were asked to make various gambling-related judgments regarding presented scratch card games. All measures used were adopted from Walker et al (2018Walker et al ( , 2019.…”

“…Within the domain of scratch card gambling, non-diagnostic (i.e. information that does not aid in assessing the true value of a card) unclaimed prize information has been shown to bias scratch card choices (Walker et al, 2019(Walker et al, , 2018. Unclaimed prize information refers to the number of prizes still available to be won and is made widely available in many jurisdictions.…”

“…Furthermore, the bias to prefer cards with high levels of unclaimed prize information persists even when in direct competition with truly diagnostic information (e.g. payback percentage), leading many gamblers to report sub-optimal scratch card preferences (Walker et al, 2019(Walker et al, , 2018.…”

Previous research suggests that intuitively appealing, yet uninformative unclaimed prize information is capable of biasing gamblingrelated judgments when people compare scratch cards that vary in the number of unclaimed prizes. However, it is unknown if the mere presence of unclaimed prize information alters a game's attractiveness. Using an online crowdsourcing platform, we recruited 402 U.S. residents to participate in an online study. In a withinsubjects design, participants made four gambling-related judgments (likelihood of winning, excitement to play, urge to gamble, and hypothetical card purchasing) for scratch cards presented with and without unclaimed prize information. Compared to cards presented without unclaimed prize information, those with unclaimed prize information were judged as more likely to win, produced more excitement to play, a greater urge to gamble, and were chosen more often during a hypothetical purchasing task. Therefore, unclaimed prize information increases the appeal of scratch card games, and may be an important aspect of the scratch card gambling environment to consider from a harm reduction perspective.

“…There were 8 information aid studies (33%) suggesting that information aids had a favorable responsible gambling impact. For example , Walker, Stange, Dixon, Koehler, and Fugelsang (2019) found that when scratch card players had access to both the number of unclaimed prizes left and the payback percentage (the ratio of unclaimed prizes to total scratch cards remaining) in a numerical format, participants were influenced by the former even though it is only the latter that is diagnostic. In a follow-up experiment, Walker et al (2019) presented the same payback percentage information using a visual (a five-star rating system).…”

Participants now more often relied on the payback percentage to make decisions about scratch cards, even though they did not understand the concept of payback percentage any better than participants in the first experiment.…”

Researchers and gambling operators have developed game-based responsible gambling tools and interventions that are intended to mitigate risks for gambling-related harm. We conducted a scoping review of this literature, with a focus on replicability and transparency. We charted 86 studies on characteristics such as study design and sample size. No tools or interventions had unambiguous evidence of efficacy, but some show promise. Pre-registration of research hypotheses, methods, and analytic plans was absent until 2019, reflecting a more recent awareness of open science practices. Published studies also inconsistently reported effect sizes and power analyses. Finally, we observed that the replicability of the responsible product design literature is uncertain but could be low. Specifically, entering each study’s primary result into a z-curve analysis—a tool for quantifying the replicability of a body of literature—revealed some evidence of publication bias based on statistical significance. Greater transparency and precision are paramount to improving the evidence base for responsible product design to mitigate gambling-related harm.
