This final paper is focused on the analysis of the ethical aspects of mobile game advertising on social networks, with a special emphasis on the phenomenon of false advertising. In the introductory parts of the paper, the key concepts of ethics, ethics in marketing and advertising, and the specifics of digital marketing, especially in the context of social networks, are presented. The theoretical framework provides a basis for understanding the challenges and dilemmas that arise in the practice of advertising, and the issue of false advertising that can significantly affect consumer perception and long-term trust in brands is highlighted. The paper also covers the development and current trends in the mobile gaming industry, which is one of the fastest growing branches of the digital economy. Monetization methods are analyzed, including freemium models, in-app purchases and advertising, which have become key sources of revenue for development companies. A special focus is placed on mobile game advertising, which is often used to attract new users, but can also involve unethical practices such as misrepresenting game content. This practice not only erodes user trust, but can lead to negative reactions and a poorer perception of the entire industry. In the empirical part of the work, research was conducted using a questionnaire among mobile game players, in order to determine their attitudes towards false advertising and its impact on the perception of brands. The results showed that most players recognize false advertising and consider it problematic. Respondents expressed dissatisfaction and loss of trust in brands that use deceptive marketing tactics. The research also revealed that current regulatory frameworks are not effective enough in preventing false advertising, and that users are not sufficiently informed about their rights and ways to report such cases. Based on the obtained results, the paper makes several recommendations for improving ethics in mobile game advertising. Greater transparency and accuracy in advertising is recommended, as well as strengthening regulation to better protect consumers. The paper also suggests that companies should invest in educating users about their rights and available mechanisms for reporting unethical practices. By implementing these measures, it is possible to improve user confidence and ensure long-term success and sustainability in the mobile gaming industry.
