<p>As organizations seek to turn knowledge into a strategic asset, gamification can strengthen motivation and engagement in knowledge management while also fostering collaborative knowledge creation. This study uses a bibliometric and systematic literature review approach, combined with content analysis, to provide a structured and balanced synthesis. The findings show that gamification supports knowledge acquisition, sharing, and creation, whereas storage, retrieval, and protection remain underexplored. In business settings, it mainly supports knowledge transfer and performance improvement, while in higher education, it enhances learner engagement and retention. The study draws on self-determination, flow, organizational knowledge, and nudge theories to explain how motivational, experiential, organizational, and behavioral mechanisms shape knowledge-sharing behavior in gamified knowledge management environments. Based on this analysis, the review proposes an integrative theoretical framework that links design fit, motivation, immersion, knowledge behaviors, coordination, knowledge conversion, and organizational value. It also identifies key challenges, including design complexity, sustaining motivation, social barriers, and knowledge validation. It links them to responses such as modular gamification, adaptive feedback, balanced incentives, and collaborative engagement. The findings further indicate sectoral differences, as businesses focus more on knowledge-sharing networks, whereas higher education applies gamification more often in structured learning settings. This research extends theoretical understanding and offers practical insights into sector-specific applications. Future research should examine knowledge creation, sharing, acquisition, and retention more closely, with attention to the effectiveness of game elements, the integration of augmented reality, individual user characteristics, implementation complexity, and long-term knowledge retention.</p>
