  248.                            <p class="info">This study explores how mobile games can be designed to enhance memory retention and recall, investigating the cognitive mechanisms involved in how players remember game events, strategies, and narratives. Drawing on cognitive psychology, the research examines the role of repetition, reinforcement, and narrative structures in improving memory retention. The paper also explores the impact of mobile gaming on the formation of episodic and procedural memory, with particular focus on the implications of gaming for educational settings, rehabilitation programs, and cognitive therapy. It proposes a framework for designing mobile games that optimize memory functions while considering individual differences in memory processing.</p>
