 For each atomic formula there is a corresponding experiment which may either fail or succeed, but may show dispersion, i.e., it may yield different results when repeated. A fixed failure probability, called risk value, is assigned to each experiment and thus to each atomic formula. The players have to pay \(\$\)1 to the other player for each of their atomic assertion where the associated experiments fails. For any game starting with my assertion of \(\varphi\) my expected overall loss of money, if we both play rationally, can be shown to correspond to the inverse of the truth-value of \(\varphi\) evaluated in an interpretation of Łukasiewicz logic that assigns the inverse of the risk values as truth-values to atomic formulas. In particular, a formula is valid in Łukasiewicz logic if and only if, for every risk value assignment, I have a strategy that guarantees that my expected overall loss at the end of game is \(0\) or negative.
