A normal-form game specifies each player's strategy set and their payoff for every strategy profile. In a finite two-player game these data form a bimatrix game; if the two payoffs always sum to zero, one payoff matrix describes the matrix game. The representation specifies choices and incentives, without a temporal order of observed moves.

A **normal-form game** is a representation of a strategic interaction among players in which each player chooses their actions simultaneously, and the outcomes depend on the combination of actions taken by all players. The normal-form game is typically represented in a matrix format, where: 1. **Players**: The game involves two or more players. 2. **Strategies**: Each player has a set of possible strategies or actions they can take.
