A Nash equilibrium is a pair of strategies where neither player can do better by unilaterally changing — the cornerstone of game theory. In the Prisoner's Dilemma both defect even though cooperating pays more; Matching Pennies has no pure equilibrium at all. Highlighted cells are the pure-strategy Nash equilibria.
