Lotteries are the most popular and widely available form of gambling. But not much is known about the communication of responsible gambling (RG) strategies and tools on the websites of lottery operators. In this study, the researchers examined the official websites of 46 state-run lottery operators in the US. They did so to identify if the websites provided information on the five RG strategies identified in the literature. The majority of sites provided information on at least one RG strategy. Advice about setting limits on gambling and providing information on gambling helplines were the most common RG strategies. Only a few sites provided information on self-exclusion or provided tools to help players set limits on their gambling. Lottery websites that reported having RG certification communicated an average of 2.95 RG strategies compared to just 1 for sites that did not. The results of the study suggest that improvements are needed by lottery operators to communicate RG strategies on their websites.
