is a game of perfect information.
Chess is an example of a game with perfect information, as each player can see all the pieces on the board at all times. Games which are
sequential (players alternate in moving) and which have
chance events (with known probabilities to all players) but
no secret information, are sometimes considered games of perfect information. This includes games such as
backgammon. However, some academic papers do not regard such games as games of perfect information because the results of chance themselves are unknown prior to them occurring. Games with
simultaneous moves are generally not considered games of perfect information. This is because each player holds information, which is secret, and must play a move without knowing the opponent's secret information. Nevertheless, some such games are
symmetrical, and fair. An example of a game in this category is
rock paper scissors. ==See also==
