Complete Information Game
A Complete Information Game is a game in which all player information is public information (available to all players).

- QUOTE: Most of this research focused on perfect information games, in which all events are observed by all players, culminating in programs that beat human world champions in checkers, chess, Othello, backgammon, and most recently, Go. However, many applications in the real world have imperfect information: each agent observes different events. This leads to the possibility of deception and a wealth of social strategies. …

- An important subset of sequential games consists of games of perfect information. A game is one of perfect information if all players know the moves previously made by all other players. Thus, only sequential games can be games of perfect information because players in simultaneous games do not know the actions of the other players. Most games studied in game theory are imperfect-information games. Interesting examples of perfect-information games include the ultimatum game and centipede game. Recreational games of perfect information games include chess, go and mancala. Many card games are games of imperfect information, such as poker or contract bridge.
Perfect information is often confused with complete information, which is a similar concept. Complete information requires that every player know the strategies and payoffs available to the other players but not necessarily the actions taken. Games of incomplete information can be reduced, however, to games of imperfect information by introducing “moves by nature” Template:Leyton-Brown.

- Complete information is a term used in economics and game theory to describe an economic situation or game in which knowledge about other market participants or players is available to all participants. Every player knows the payoffs and strategies available to other players.
Complete information is one of the theoretical pre-conditions of an efficient perfectly competitive market. In a sense it is a requirement of the assumption also made in economic theory that market participants act rationally. If a game is not of complete information, then the individual players would not be able to predict the effect that their actions would have on the other players (even if the actor presumed other players would act rationally).
