The boiling point of a class of games $S$ is the supremum of all temperatures in $S$. We show that the boiling point can be bound by the maximum length of the confusion intervals of games in $S$. Further, we give a technique of how to bound, in turn, the length of the confusion interval. As an application example, we show that the boiling point of certain Domineering snakes is at most 3.
