Nash Equilibrium Finder

Best-response correspondences and equilibrium computation

Build a 2×2 payoff matrix and see all Nash equilibria — pure and mixed. The best-response diagram shows where each player's correspondence intersects, pinning down equilibrium strategy profiles.

Edit payoffs to see Nash equilibria shift. White dots mark equilibrium intersections of best-response correspondences.
