As the Internet offers a new venue for gambling, the risks for engaging in pathological behaviors are potentially increased. In light of this, a systematic literature review was conducted in order to shed further light on the relationship between gambling on the Internet and possible addiction by assessing Internet gambling in general and addictive gambling on the Internet specifically. Based on previous research, it is argued that a combination of individual, situational, and structural characteristics determine whether and to what extent individuals engage in Internet gambling. The results suggest that there are more problem gamblers on the Internet than in land-based venues. A reason for this may be the structural characteristics of the Internet inherent to this technology, namely availability, ease of access, anonymity, and convenience. In conclusion, however, the Internet cannot be claimed to be addictive per sé, but rather to facilitate the engagement in addictive behaviors, including gambling.
