In recent years, "gamification" has gained significant popularity due to technological advancements and has been widely adopted across various sectors. One such sector is e-commerce, which has transitioned from traditional retail to online platforms. The Covid-19 pandemic, which recently affected global consumption habits, is considered a major reason for the increased inclination towards online shopping, contributing to the growth and transformation of this sector. Mobile applications are one of the key components of this transformation. Positive developments in internet access have led consumers to shop online, causing the e-commerce sector to increasingly leverage mobile technologies and related applications, enhancing market dynamics and intensifying competition among brands. In such a competitive environment, e-commerce brands are compelled to develop different strategies and paradigms to enhance customer satisfaction and sales rates. Gamification emerges as a method directed by industry experts in the e-commerce sector, involving strategies like points, rewards, levels, competitive activities, and enhancing user experience to make it more enjoyable and increase customer satisfaction. For these strategies to be effective, the visual design of the developed mobile applications also needs to be successfully organized within the process. To successfully describe a product consisting of different dynamics such as e-commerce, gamification, and visual design, it is necessary to examine the current state of their structural features and their interactions. Based on this, the article conducts a case study examining five mobile applications in the e-commerce sector that utilize gamification methods, exploring whether the term "gamification" undergoes semantic and methodological changes across sectors, and how visual designs developed for gamification adapt to sectoral dynamics. The study of gamification designs in e-commerce mobile applications indicates that this trend will continue to grow and gain importance in the future.
