In a zero-sum game, what is the outcome for one player's gain?

In a zero-sum game, the outcome for one player's gain is that it directly results in the loss of the other player. This means that the total amount of benefit or value in the game remains constant. For example, if one player wins $10, the other player loses $10, so the total money in the game stays the same. This idea shows that in zero-sum games, players are in direct competition, and one player's success comes at the expense of the other. Therefore, understanding this concept is important for strategizing in competitive situations.
