Abstract: Bernard Suits was a famous American sports philosopher, who devoted his life to probing into concepts such as playing, game and sport etc., and their relationships, and made tremendous contributions to the development of game philosophy. Suits’ game philosophy mainly includes 4 aspects, i.e. playing, game playing, game playing and utopia, and the relationships between playing, game and sport. The debates about playing focused on whether playing involves re-source redistribution, and whether the autotelic purpose is objective; the debates about game playing focused on whether the game is definable, whether the definition is too broad or too narrow, and whether the definition content is accurate; the debates about game playing and utopia focused on whether utopia is perfect, and whether game utopia ex-ists; the debates about the relationships between playing, game and sport focused on whether there is a cross relation-ship between the three, and whether the classification criteria have type errors. Suits’ game philosophy is conducive to examining sports phenomena and problems nowadays.
