The coke example Brandon gave is a good one. The essence of zero-sum games is just like he said: what one player gains is exactly offset by what the other player loses, so the sum of payoffs equals zero. That's why they're called

Thank you for replying. I only have one question....did you stop talking about it at the "Coke" part? Because that was as far as I could see. Thank you...if there are more parts, please e-mail me. And if anyone else out there [View full text and thread]

Hi! I'll try my best. Here goes.....
Zero-sum games are those games for which the payoffs to the players sum to zero (they add up to zero) for all possible strategy combinations. If this is represented in a payoff matrix (called the normal form) as compared to the extensive form (with game tree), only 1 payoff (the payoff to the row player) is given for each pair of strategies. This is the convention for zero-sum games. So, if you see a game which is represented by a payoff matrix and only one payoff is shown, it would be a zero-sum game. An example could be when 2 firms in the market, and only these 2 firms (duopolists) compete over market share. Here, we can understand that a firm's gain in market share is the loss of the other firm.

Say, you play a small game with your friend (perhaps Monopoly) and the loser gets to buy a drink for the winner. :) It's a zero-sum game. The winner gets a coke, the loser looses the coke. :) One coke minus one coke = zero coke [Manage messages]

I am a high school student trying to learn about Zero-Sum games. I have read many things about it, but because of my lack of knowledge, it is uncomprehensible to me. Could somebody please help explain it in "elementary" terms? Please [View full text and thread]
