Sequential Games

Sequential games are games that require players to take turns to make decisions based on previous actions. Unlike simultaneous games, where all players declare their actions at the same time, sequential games involve a process of information exchange and action selection that can affect the outcome of the game.

A well-known example of a sequential game is chess. Chess is played by two opponents who explore each other’s moves and respond with their own. Each move is based on the knowledge of what the opponent’s moves have been so far, and the goal is to find the optimal move that will lead to a good outcome in the future.

In the scientific literature, sequential games are known as dynamic games. This means that the rules of the game, the strategies available, and the payoffs all depend on the order in which the players act. As such, the strategies of a sequential game need to be carefully chosen to maximize the players chances of winning.

Sequential games can be both cooperative and non-cooperative. In cooperative games, players are expected to cooperate to achieve a mutually beneficial outcome, such as in the game of Noughts and Crosses. In contrast, non-cooperative games test players’ best strategies for competing and involving themselves in conflicting situations, such as Poker.

One of the key concepts for understanding sequential games is that of equilibrium. In an equilibrium, both players apply the same strategies and no single player has an incentive to unilaterally change. As such, this is when the game reaches its most optimal outcome.

Sequential games often involve the concept of “strategic uncertainty”, which means that the players do not know the exact steps the opponent will take. As such, the players need to anticipate the possible actions of the other player and act accordingly. This can lead to the concept of an “information cascade”, where the players take decisions that are based on the past actions of the players, rather than on the optimal actions to improve their chances of winning.

Sequential games can also be used to analyze decision-making processes in other areas, such as economics and politics. For example, the Prisoner’s Dilemma is a famous example of a sequential game used to model economic and political behavior. In this game, two participants must decide whether to cooperate with each other or to pursue a selfish strategy.

Sequential games are an important part of game theory, providing a method for analyzing multi-stage decision-making processes. They are used to model complex decisions, ranging from economic and political choices to competitive games like chess and poker. By understanding the underlying principles of sequential games, researchers can gain insight into strategic decision making in many different contexts.

Sequential games are a broad category of games where players take their turns in a predetermined order. The order of play is determined by the game rules and does not change during the game. Each player must choose his move based on the moves made by previous players. Examples of sequential games include chess, Go, and tic-tac-toe.

One particular type of sequential game, called a zero-sum game, involves two players who are trying to oppose each other. Each move a player makes attempts to increase their gains while reducing their opponents gains. Examples of such games include poker, blackjack and the Prisoners Dilemma.

In order to make the best possible decision, a player in a sequential game should consider the opponents possible moves in light of the games rules. That is, the player should strategize for each move and consider the possibility of their opponents response. For instance, a chess player might consider what kind of move their opponent might make in response to a given move, and then choose the response that would be most beneficial to them.

Sequential games are an important teaching tool in game theory. By considering strategic moves and incorporating the oppositional strategies of other players, players can gain important insight into decision-making and effective strategies.
