In this work, we focus on game interpretations of fuzzy logic. We present fuzzy methods, which encompass fuzzy logic and fuzzy mathematics and offer a few examples of their applications in finance. We then present three types of game for fuzzy logic, namely Hintikka games, Giles' game and coupling games. We look at Hintikka games in the context of both propositional and fuzzy logic. For Giles' game, we add strong forms of conjunction and disjunction to fuzzy logic. The main contribution of this work is to present the novel notion of coupling games and to give a proof of a determinacy theorem for them.
