In the following 3 lessons you will be introduced to some core theories and concepts within game studies. One of the most basic questions is how to distinguish between play and non-play. We have many ways of doing this and one of the often-cited concepts is that of the magic circle as a metaphor for describing the complex set of social relations. While within the magic circle, the players adopt a lusory attitude as one of the basic building blocks of games.

After having read about the magic circle, the lusory attitude and the different rules of games, you will be asked to test your knowledge in the final exercise on Core Concepts in Games sand Gaming.
