Gambit features a visual extensive form editor as well as a command language version.
The general purpose of the language is to allow the user to perform operations and procedures on games in extensive or normal form. Games can be built and manipulated in the program and stored or loaded from external files. Games created in the extensive form can be transformed into the normal form and solved, either in extensive or normal form, for various equilibrium concepts. Gambit also has a command language that is suitable for econometric analysis of data from game theory experiments. You can download a copy of the Gambit software here .
