Video games have become one of the most popular ways people spend their free time in modern society. Whether they are played for fun, relaxation, or entertainment, video games have become incredibly popular and highly profitable. Recently, people have started using elements from video games for purposes beyond just entertainment, and the term for this is gamification. Gamification is being introduced into businesses to improve employee performance and motivate them to work, and it is also being integrated into education to engage students in a fun yet educational way, encouraging them to learn and understand the material. This paper will explore how gamification can assist in waste management in the city of Split. Through empirical research, the habits of Split's citizens regarding video games, their opinions on waste sorting in the city, and their awareness of the concept of gamification will be examined. Finally, gamification and waste sorting will be combined through an application based on elements used in gamification. This theoretical overview of gamification and empirical research can serve as a resource for professionals working with gamification in the city of Split and throughout Croatia, helping them understand citizens' habits and analyze their opinions.
