A win-win situation, also called a win-win game or non-zero-sum game in game theory, is a situation by which cooperation, compromise, or group participation leads to all participants benefiting. The term can be applied to many aspects of daily living, and it is contrasted to the zero-sum game or win-lose situation, where the dominant factor is that at least one person wins while another loses. These are also called zero-sum games and examples include most two-person board games. For instance a chess game is zero-sum. One winner, +1, is added to one loser, -1, resulting in a total of zero.
