An educational game is a game specifically designed, adapted, or intentionally used to achieve defined learning objectives through structured gameplay [1][2][3][4]. It combines pedagogical content with game mechanics—such as goals, rules, feedback, challenge, and progression—so that learning occurs as an integral part of player interaction rather than as an external add-on [1][2]. Educational games may target knowledge acquisition, skill development, problem solving, motivation, or attitude change, depending on instructional design and context [2][3][4]. A core characteristic is alignment between curriculum goals, assessment criteria, and game activities, ensuring that success in the game reflects intended educational outcomes [1][2][3]. In educational research and practice, the term denotes purpose-driven game-based learning tools, distinct from entertainment games used without explicit instructional design [1][2][3][4].
