Normal form games are fundamental tools in game theory that are used to model a wide variety of strategic situations. These games are characterized by a set of players, a set of strategies available to each player, and a payoff function that determines the outcome of the game for each player based on the strategy choices made by all players. While "normal form game" is the most common term used to refer to these games, there are several synonyms that are also used, such as strategic form game, matrix game, payoff matrix game, and static game. These terms all refer to the same basic concept, and are used interchangeably in game theory literature.
