Fantasy football is a game in which the participants serve as general managers of virtual professional gridiron football teams. The competitors choose team rosters by participating in a draft in which all players of a real football league are available. Points are based on the actual performances of the players in the real-world competition. The game typically involves the National Football League, Canadian Football League, or college football.
There are two main types of fantasy football:
Traditional in which the competition can run either for an entire season or many seasons if it is a keeper league,
Daily is an accelerated version in which the contests are conducted over shorter periods, such as a week or a single day. Daily fantasy football is managed by commercial internet companies who charge a percentage of each betting pool. In the United States, the two largest firms are FanDuel and DraftKings.
