If both players defect, they both receive the punishment payoff ''P''. If Blue defects while Red cooperates, then Blue receives the temptation payoff ''T'', while Red receives the "sucker's" payoff, ''S''. Similarly, if Blue cooperates while Red defects, then Blue receives the sucker's payoff ''S'', while Red receives the temptation payoff ''T''. − − If both players cooperate, they both receive the reward R for cooperating. If both players defect, they both receive the punishment payoff P. If Blue defects while Red cooperates, then Blue receives the temptation payoff T, while Red receives the "sucker's" payoff, S.

传统囚徒困境的结构可以从其最初的囚徒环境中概括出来。假设两个玩家用红色和蓝色表示，并且每个玩家选择“合作”或“背叛”。
传统囚徒困境的结构可以从其最初的囚徒环境中概括出来。假设两个玩家用红色和蓝色表示，并且每个玩家选择“合作”或“背叛”。
如果两个玩家合作，他们都会因为合作而获得奖励''R''。如果两个参与人都叛变，他们都会受到惩罚''P''。 如果蓝方叛变而红方合作，那么蓝方得到诱惑回报''T''，而红方受到“上当受骗者”损失''S''。同样地，如果蓝方合作而红方叛变，那么蓝方得到上当受骗者的损失''S''，而红方得到诱惑支付''T''。
