  Suits draws on his definition of games to provide a definition of sport. He defines sports as ‘games of physical skill’ (Suits, 1988, 2), incorporating the elements of his earlier definition of game and adding further elements that are distinctive to sport as compared to other types of games. In particular, a game becomes a sport by meeting the following criteria: ‘(1) that the game be a game of skill; (2) that the skill be physical; (3) that the game has a wide following; and (4) that the following achieve a certain level of stability’ (Suits, 1973 [2007]). Thus, the outcome of the game must be dependent on the exercise of physical skills. This is what differentiates sporting games from card games or chess, for example (see Kobiela, 2018 and Hale, 2008). In the latter, the way the body is moved is irrelevant, and what matters are the moves made (either with cards or pieces on the board). Indeed, such games can be played in non-physical spaces such as virtual reality and by non-human players such as computers. However, in soccer or boxing, the skillful control of the body is essential to the achievement of the goal of the game.
