The distinction between gambling and gaming is becoming increasingly blurred due to technological convergence—the integration of various digital activities. This special issue examines how this shift affects individuals, particularly those vulnerable to gambling-related harm. Key topics include social casino games, simulated internet gambling, skill-based gaming machines, gambling features on Twitch.tv, and the potential for gaming to act as a gateway to gambling. As digital gambling technologies continue to evolve, the research highlights the need for further study and regulatory responses to mitigate risks and support public health efforts.
