Purpose of Review The internet and virtual environments have enabled the formation of online communities around a variety of interests. Online communities focused on gambling are increasingly popular and attract users to interact and share ideas and experiences with likeminded others. This study reviews evidence from the latest research examining the role of online communities in gambling behaviors and gambling problems.Recent Findings A systematic literature search resulted in 17 studies. Research shows that online communities are used for diverse reasons like discussing gambling experiences and problems, sharing tips, and celebrating winnings with others. These reasons of online community use can have both adaptive and maladaptive implications. Online gambling communities often grow through social means by inviting friends or social media contacts to join. Active users of online gambling communities are more likely at-risk or problem gamblers.Summary Online communities have an increasingly central role in learning about gambling, continuing, and spreading of gambling behaviors. Participation in communities that support harmful gambling habits involves risks for problem gambling.
