The first was the influence of family members and other adults in participating in gambling, and the second was the link between gambling and culturally valued events. These two factors were often intertwined. While a few children specifically reported having gambled on scratch cards and on Keno, most children who had participated in gambling had bet money on horse races or sporting events: “I’ve done horse racing with one or two dollars”. Children’s gambling was mostly linked to betting with or against adults. Sometimes children described engaging in “fun” bets with family members and family friends. While these bets rarely involved money, they related to specific events during sporting matches, such as which player would kick the most goals.
