A game, which is generally played by two or more players, is known as a multi player game. The player may be playing individually with another player as an opponent or may form teams to play against each other. Theoretically speaking, it is quite difficult to analyze many independent players playing in a single multi player game as it may result in coalitions.
Keeping in mind that the coalitions between players are actually not allowed, John Nash had proved that a stable solution can be provided in games with several players. Nobel prize was also awarded to him for economics for the extension of Von Neumann's theory of zero sum games. This stable strategy provided by him is known as Nash equilibrium. The situation becomes more complex if the cooperation among the players is allowed. The theories provided by Nash have certainly some impact in the field of economics, politics etc.
It has been found that, with the advent of the quantum information into the quantum game theory, a new horizon has been opened for the multi player games. It has been allowing a new type of equilibrium strategy which is generally not available in the traditional games. According to this strategy, the contract or the amount of money that is kept as a bet, mainly in card games, can be affected by the player's choices but the player is not allowed to make any sort of profit by means of betrayal.
