Daily fantasy sports (DFS) is a type of online game where participants create virtual teams made up of real professional athletes. Players compete based on the actual performance of these athletes in real-life games. Unlike traditional fantasy sports, which last an entire season, DFS contests typically last just one day or one week. Participants enter contests by paying an entry fee, and they can win cash prizes based on their team's performance. DFS is popular for various sports, including football, basketball, and baseball. Players can join public leagues or create private contests with friends, making it a flexible and engaging way to enjoy sports.
