Daily fantasy sports leagues compress traditionally season-long leagues into one day or a weekend of competition. While members draft teams just the same, instead of keeping the same players throughout the entire season, such leagues do not require a season-long commitment.
Since members are not competing for players throughout the season, daily fantasy sports leagues are more numbers-driven than season-long leagues. While they are relatively new, the daily fantasy sports leagues are gaining in popularity, with an increasing number of sports gaming sites are offering them. FanDuel and DraftKings are considered the two of the industry's largest pay-to-play daily fantasy sports sites.
