Sequential game

Sequential games are governed by the time axis and represented in the form of decision trees.

They show the sequence in which players act and the number of times that they can each make a decision.

Extensive form representations were introduced by Neumann and further developed by Kuhn in the earliest years of game theory between 1910–1930.

One example of a simultaneous game is rock-paper-scissors, where each player draws at the same time not knowing whether their opponent will choose rock, paper, or scissors.

A strictly determined game only has one individually rational payoff profile in the 'pure' sense.
