The Nash equilibrium is a concept of game theory. This is a theory in which the optimal outcome of a game is one where no player has an incentive to deviate from his or her original chosen strategy after considering an oponent's choice. This concept is named after the mathematician that invented it, John Nash.In this game state each player must be doing the best that they can given the strategies of all the other players.

Mathematically if a game is truly played using the Nash equilibrium it will come out as perfectly as possible according to the rules that are applied to every game.
