Duel of Spin is a 3D strategy game designed to teach players about rotational motion through engaging, physics-based gameplay. The context analysis identifies a key challenge: while strategy games are effective for STEM learning, they are not popular among teenagers. To address this, enhancements in visual appeal, feedback mechanisms, and thematic relevance are proposed to make the game more appealing to this demographic. The game covers learning contents that the target audience typically lacks life experience with, including torque, angular velocity, and moment of inertia.
