The Repeated Game

The Repeated Game is an Iterated Prisoner's Dilemma and Reputation scenario. The core lesson: The shadow of the future transforms a defection game into a cooperation game. You're playing Prisoner's Dilemma with the same opponent, repeatedly, for an unknown number of rounds. They will remember everything you did. DecisionPlay maps the players, payoffs, and equilibrium dynamics that shape how this situation typically resolves.

Frequently Asked Questions

What game theory model does this scenario illustrate?
The Repeated Game illustrates Iterated Prisoner's Dilemma, Reputation. The shadow of the future transforms a defection game into a cooperation game.
What is the Nash equilibrium?
DecisionPlay computes equilibria using best-response iteration and support enumeration. See the interactive analysis for this scenario.
Is this based on a real situation?
Yes. DecisionPlay's library is drawn from real-world conflicts, negotiations, and decisions.
How accurate is the analysis?
DecisionPlay uses a deterministic game-theoretic core with an LLM-based classifier. Verify edge cases against the structural module.
