An interactive lab for exploring 2×2 game theory — the math of strategic decisions like the Prisoner's Dilemma. Build your own payoff matrix, and the tool finds the Nash equilibria (both pure and mixed strategies), explains the best-response logic, and includes a Rock-Paper-Scissors reference for zero-sum mixed strategies. A fast, portable way to build intuition for how rational players make decisions.
- Custom 2×2 payoff matrix builder with presets
- Pure and mixed Nash equilibrium solver
- Best-response logic explained step by step
- Zero-sum / mixed-strategy reference (Rock-Paper-Scissors)
