ZeroSum

A game is ZeroSum if there's a fixed amount of points available and one player can't gain points without another (or others) loosing an equivalent number of points. In contrast, a NonZeroSum game has the possibility that players can make moves which benefit them both.

• On QuestionsINeedAMathematicianToAnswer I was wondering whether, in principle there are more ZeroSum games or NonZeroSum games.

• NonZero discusses this.
