An extensive-form game is a specification of a game in game theory.

Extensive-form games allow explicit representations of a number of important aspects, including:

The sequencing of players' possible moves
Their choices at every decision point
The (possibly imperfect) information each player has about the other player's moves when he makes a decision
His payoffs for all possible game outcomes.

Extensive-form games also allow representation of incomplete information in the form of chance events encoded as "moves by nature".

Extensive-form games are usually used for sequential games, since extensive-form games explicitly illustrate the sequential aspects of a game.
