The concept of metagames can be of use to philosophers of sport and games. However, the term “metagame” is used throughout the literature in several different, distinct senses, few of which are clearly defined, and as a result there remains ambiguity about what, precisely, this term means. In this paper, I attempt to disambiguate the term metagame. I have come across at least four different senses of “metagame” in academic literature about games. Of these four senses, most relevant to philosophers (...) of sport and games is what I have termed “ludic” metagames. Ludic metagames involve playing a game “on top of” another game. I attempt to spell out this concept in particular detail, distinguishing it from related – but distinct – ways in which the formal features of a game can be modified without giving rise to metagames.
