Digital games, with their unique interactivity, entertainment value, and immersive experiences, have opened up new pathways for the protection and dissemination of cultural heritage. This paper first explores the role of digital games in cultural heritage protection, analyzing their significant potential in areas such as the digital archiving of artifacts, virtual restoration, and immersive exhibitions. Secondly, with a focus on cultural heritage dissemination, this paper examines the mechanisms through which digital games enhance public engagement and improve the effectiveness of cultural heritage education. Finally, the paper emphasizes the design strategies for museum digital games, highlighting the critical roles of core design elements such as cultural sensitivity, educational objectives, interactivity, immersive experiences, and feedback mechanisms. The research demonstrates that the effective use of digital games as an innovative medium can not only substantially enhance the social impact and public engagement of museums but also provide novel solutions for the protection and innovative development of cultural heritage. This approach fosters the deep integration of traditional culture and modern technology, achieving a harmonious coexistence between the two.
