A game can be any recreational activity which involves one or more players. A game can be based on a common goal which the players need to achieve or it can be based on a set of rules that govern the game and determines what the players can or cannot do. Games can further be categorized as an outdoor game or an indoor game. Games are primarily played for entertainment and as a form of recreation, but at times there are certain games that can be played for educational purposes and to improve a person's knowledge for e.g. a quiz game.
