  99.                    <p>This paper examines the potential of augmented reality (AR) in educational mobile games, focusing on how AR can be used to create interactive learning experiences that enhance knowledge retention and student engagement. The research investigates how AR technology can overlay digital content onto the physical world to provide immersive learning environments that foster experiential learning, critical thinking, and problem-solving. Drawing on educational psychology and AR development, the paper explores the advantages and challenges of incorporating AR into mobile games for educational purposes. The study also evaluates the effectiveness of AR-based learning tools compared to traditional educational methods and provides recommendations for integrating AR into mobile games to promote deeper learning outcomes.</p>
