A serious game is a game designed not primarily for entertainment, but for an external practical purpose such as education, learning, social practice, or policy simulation. In the provided context, serious games are described as a kind of “social laboratory” in which participants temporarily step outside everyday interests and operate within a magic circle governed by different rules. This makes it possible to examine complex issues such as resource allocation, governance models, and structural bias in a safe and structured setting.

The key point is not to keep knowledge or attitudes confined inside the game. Rather, the goal is to transfer the judgments, skills, and perspectives gained in play into real-world learning, work, and social participation. For that reason, the ideal boundary of a serious game is neither fully closed nor fully open: it should be closed enough to allow safe trial and error, role exchange, and simulation, but open enough for learning outcomes to move outward into practice. The context also suggests that serious games can help participants deconstruct fixed assumptions, develop empathy, and cultivate systems thinking. However, based only on the supplied passages, the term is best understood here as an educational and socially applied form of game design centered on controlled permeability between play and reality.
