  194.                            <p class="info">This study compares the educational efficacy of mobile games designed for learning with those created purely for entertainment purposes, examining their impacts on knowledge retention, critical thinking, and problem-solving skills. Drawing from educational theory, cognitive psychology, and game design, the research evaluates how various game mechanics—such as points, challenges, and feedback loops—affect learning outcomes. The paper investigates how mobile games can bridge the gap between fun and education, proposing a framework for creating hybrid games that are both enjoyable and educational. The research also addresses the challenges of assessing learning outcomes in gamified environments and the role of player motivation in educational success.</p>
