  An essential element of K-12 AI literacy is educating learners about the
ethical and societal implications of AI systems. Previous work in AI ethics
literacy have developed curriculum and classroom activities that engage
learners in reflecting on the ethical implications of AI systems and developing
responsible AI. There is little work in using game-based learning methods in AI
literacy. Games are known to be compelling media to teach children about
complex STEM concepts. In this work, we developed a competitive card game for
middle and high school students called "AI Audit" where they play as AI
start-up founders building novel AI-powered technology. Players can challenge
other players with potential harms of their technology or defend their own
businesses by features that mitigate these harms. The game mechanics reward
systems that are ethically developed or that take steps to mitigate potential
harms. In this paper, we present the game design, teacher resources for
classroom deployment and early playtesting results. We discuss our reflections
about using games as teaching tools for AI literacy in K-12 classrooms.
