Online casinos are one of Sweden’s largest gambling sectors. Increased advertising investment and advertising frequency have sought to attract Generation Y consumers to these casinos, yet it has been suggested that advertising can contribute to avoidance behaviours towards products and services, including online casinos and specific gambling brands. The various advertising aspects used in gambling advertising and their impact on behaviour have not been widely researched. Thus, the purpose of this study was to explore the use of creative strategies in casino advertising and how it contributes to the avoidance of online casinos, specifically among Swedish Generation Y consumers. As an exploratory study, qualitative methods were used. Initially, 13 casino advertisements were analysed to identify the strategies used in the advertisements. These were then presented to Generation Y consumers in three focus groups and six in-depth interviews. The analysis of the advertising shows the use of people and characters in presenting the casino brand. Male voice-overs were utilised in addition to music and other casino-related sounds. The advertising also used bright colours to attract attention. The impact of these advertisements is that the content, the auditory cues rather than just music, the emotional response, and the frequency of the advertising were found to contribute to the avoidance of casino brands. Furthermore, the ethics and general attitudes to the industry impact the decision to avoid these brands. The managerial implication of this research shows the impact of advertisements on the decision to avoid a brand, specifically a casino brand.
