Representation of a game:

In order to solve a game it  is necessary to have a clear  idea of who the players are, what their  strategies are and what payoff  is going to be generated after the strategies are chosen  by  the players.  Sometime  this  information  is  bulky  and not  easy to conceptualise. Therefore, to make things simpler, we  represent games  in  a convenient way. This  is called  forms of a game. Games could  be normal form type or extensive form type.  

1) Normal Form Games

2) Extensive Form Games
