So why do we then play them? [Here, if the payoffs are in dollars, Player 1 can expect to win $0.20. In both instances you cannot just continually play a pure strategy like heads or stone because your opponent will soon catch on and play the associated winning strategy. They are fun, we like the competition, and, since we usually play for a short period of time, the average winnings could be different than 0. An instance of the game from beginning to end is known as a play of the game. In a play of the game, Player 1 shows one card, and Player 2, ignorant of Player 1s choice, shows one card. Game theory has outstanding effects on the theory of economics, and the literature on applying game theoretical and related approaches to economics is growing rapidly, and yet many theoretical and empirical challenges remain in this field. Player 1 wins if the suits match, and Player 2 wins if they do not. How much would you expect to win? As a mathematical tool, the game theory model has gained a lot of applications in the economic, the biology, and the telecommunication, and so on. (2) Every possible combination of plays available to theplayers leads to a well-defined end-state (win, loss, ordraw) that terminates the game.
