today's world, soft skills such as problem-solving, critical thinking, effective communication, and collaboration are considered essential components of success in the 21st century. Despite growing emphasis on their importance, there are still challenges in teaching these skills effectively. The integration of mobile learning technologies with gamification can provide an engaging and motivating environment that fosters the development of soft skills and increases student participation in the learning process. The present study aimed to review existing research on the impact of gamification-integrated mobile learning on soft skills development. This research employed a systematic review methodology. The study population included peer-reviewed articles published between 2017 and 2024 in databases such as Scopus, ScienceDirect, ERIC, and Google Scholar. A total of 142 articles were identified; after applying inclusion and exclusion criteria and conducting initial screening based on the PRISMA guideline, 20 eligible articles were selected and analyzed. Findings revealed that gamified mobile learning fosters time management, self-regulation, and responsibility by enhancing intrinsic motivation, active participation, goal-oriented interaction, and self-directed learning. Moreover, collaborative activities, immediate feedback, and competitive structures were found to enhance skills such as collaboration, critical thinking, and problem-solving. In conclusion, gamification in mobile learning environments holds significant potential for cultivating key 21st-century competencies
