 It should be stressed once more that logic is not the only formal discipline that throws light on games. Quantitative probability enters the study of games in many ways, both in classical and in evolutionary game theory. The interface of logic and games may well profit from the many old and new contacts between logic and probability (Leitgeb 2017; Lin &amp; Kelly 2012; Harrison-Trainor, Holliday, &amp; Icard 2016).
