The lack of effective safety education training in curriculum design could expose children to serious safety accidents both in schools and at homes in China. To highlight the importance of safety education, this study was intended to design and implement an adventure video game (AVG) on mobile devices, hoping to improve children’s safety knowledge and skills through interactive gameplay. The proposed AVG app situated children in real dangerous circumstances through roleplaying and then engaged them in learning safety re-lated knowledge through case scenarios. To balance the entertainment and edu-tainment of the game, this app integrated theories of game design and child de-velopment to support its design rationale, including interface interaction and game badges. This app was evaluated through interviews and video analysis so that later improvements were made according to feedback from participants, parents and experts.
