The increasing convergence of the gambling and gaming industries has raised questions about the extent to which social casino game play may influence gambling. This study aimed to examine the relationship between social casino gaming and gambling through an online survey of 521 adults who played social casino games in the previous 12 months. Most social casino game users (71.2%) reported that these games had no impact on how much they gambled. However, 9.6% reported that their gambling overall had increased and 19.4% reported that they had gambled for money as a direct result of these games. Gambling as a direct result of social casino games was more common among males, younger users, those with higher levels of problem gambling severity and more involved social casino game users in terms of game play frequency and in-game payments. The most commonly reported reason for gambling as a result of playing social casino games was to win real money. As social casino games increased gambling for some users, this suggests that simulated gambling may influence actual gambling expenditure particularly amongst those already vulnerable to or affected by gambling problems.
