This article reviews past studies that assessed the efficacy of harm-minimization tools for controlled gambling. Harm-minimization tools aim to make time spent gambling safer. For example, warning pop-up messages or reducing opening hours of gambling venues. The authors categorized the tools by their main purpose (i.e., breaks in play, messaging, limit-setting, behavioral tracking, and banning or modifying bank note acceptors). They summarized evidence on how well each category of tools works.
