Background and aims: The convergence of gaming and gambling may pose a risk for adolescents. Thus, it is important to find out how these behaviours are associated with other addictive behaviours in order to develop efficient preventive measures for youth. The aim of this study was to examine 1) whether problematic gaming and money used for gaming activities are risk factors for gambling, and 2) what kind of impact adolescents? substance use along with other factors related to friends and parents have on this association. Methods: The European School Survey Project on Alcohol and Other Drugs data, 2019 of Finnish adolescents aged 15 to 16 (N 5 4595). Cross-tabulations with Rao-Scott?s chisquare tests were applied to study the associations of the background factors with gambling in the past 12 months. A multinomial logistic regression model was fitted for the outcome variable (gambling in the past 12 months) adjusted for all independent and background variables. Results: Problematic gaming alone was not associated with gambling participation, whereas using money for digital games increased the risk of gambling. Boys gamble more than girls. The use of alcohol and drugs increased the risk of gambling. Parental monitoring reduced the risk of gambling, whereas hanging around weekly with friends increased the risk. Discussion and conclusions: Using money on gaming sites may put some adolescents at risk of developing problems with either gaming or gambling. The link between using money in digital games and gambling participation calls for preventive measures, intervention and regulatory acts.  Kulcsszavak: gambling; gaming; digital games; adolescence; youth; ESPAD
