How is Underdog DFS Different than DraftKings or FanDuel?

One main feature that sets Underdog Fantasy apart from other DFS platforms like DraftKings and FanDuel is its unique drafting format. Instead of traditional salary cap drafts, Underdog Fantasy uses a snake draft format where players take turns selecting their rosters in a serpentine order. This adds an extra layer of strategy and skill to the drafting process.

Underdog Fantasy also offers various contest types, including head-to-head, 3-man, 6-man, 10-man, and 12-man contests, and Best Ball, a season-long format where the best players from each week count towards your total score.

Underdog FAQ

What is Underdog Fantasy?

Underdog Fantasy is a leading fantasy sports site with easy and exciting gameplay. Underdog is known for using live drafts-based play and offering player prop competitions. Player props are the fastest growing—and many believe—the most rewarding way to play fantasy sports. Underdog Fantasy may be the best site for fantasy players who follow player stats and enjoy testing their knowledge about their favorite players in the NBA, NFL, NHL, MLB, or other major sports leagues.

They are growing quickly, and prize payouts are potentially large—and rumor has it—will grow exponentially this year. Now is the time to learn how to play with Stokastic's newly updated and verified promo code.

Is Underdog Fantasy Legit?

Yes! Underdog is an established, U.S.-based fantasy sports company backed by high-profile investors such as Kevin Durant, Mark Cuban, and Jared Goff. While less widely known than DraftKings or FanDuel in fantasy sports, Underdog Fantasy has a wide following and unique gameplay style that many players prefer and find fairer to beginner and intermediate players.

Underdog also has an excellent first-time sign-up bonus available through our website. Click through any link on our site, and the new sign-up Underdog promo code will be instantly added as you create your account.

Underdog Fantasy Sports Review

Live Drafts

Underdog Fantasy offers live draft rooms for users to draft players against other users in the contest. It follows the typical snake draft format, with a player able to be drafted only once. Drafts are available for daily, weekly, and even season-long contests, with NFL Best Ball drafts being among the most popular.

Prop Contests

Instead of building lineups with a salary cap, Underdog Fantasy offers an extensive list of props for users to play. Pick the over/under on points, rebounds, home runs, and more across various sports. Users can parlay multiple sports picks together for a higher payout. Picking five props and getting them all correct wins users 20x their entry fee. Many users prefer these contests since they only compete with themselves and not hundreds of other users.

Underdog Fantasy is entirely different from the most popular DFS sites using a typical salary cap-based format where users build lineups of players. Underdog Fantasy offers player props, where props either hit or miss, instead of players earning fantasy points. While other sites provide prop contests, Underdog Fantasy allows you to choose the props you are most comfortable with. This is a significant advantage over other sites.

Then, Underdog Fantasy also has live drafts with other users. While the main idea of earning the most fantasy points is similar to other sites, drafting players with other users is a unique way to build lineups. It also prevents the entire contest from rostering the same player.
