What is Underdog Fantasy?

Nine years ago, daily fantasy sports sites were popping up left and right. Things have shifted since then, with FanDuel and DraftKings cementing themselves as industry leaders. While our options have largely consolidated, all fantasy sports lovers, whether it be DFS or season-long, NFL or NBA, should beware of the Underdog — Underdog Fantasy, that is.

Spearheaded by founder Jeremy Levine, a veteran in the DFS industry who previously founded the sites StarStreet and Draft, Underdog Fantasy is Levine’s most ambitious fantasy sports project yet. And it’s safe to say people, including some major personalities and investors, have taken notice.

After a successful rollout ahead of the 2020 NFL season, a plethora of big-name investors, including Mark Cuban, Kevin Durant, Adam Schefter, The Chainsmokers, Nas, Future, and more, wanted to place their bets on Levine and his Underdog Fantasy team in 2021.

With a team like that, you know the product is going to be awesome. So let’s take a closer look at what Underdog Fantasy has to offer and what differentiates it from other sites.

Why Sign Up at Underdog Fantasy?

As mentioned, Underdog Fantasy is a newer site, but it was founded by industry veterans. The Underdog app is one of the best in the gaming industry, as you can see by its ratings in mobile app stores. On Google Play, the Underdog App has been downloaded more than 50,000 times and has a 4.5-star rating. In the App Store, Underdog Fantasy has a 4.7-star rating and ranks 27th among top Sports apps.

Underdog Fantasy Sign-Up Process

Aside from a user-friendly app and awesome promotions, there are a few more reasons you should choose Underdog Fantasy.

  • Better than traditional fantasy leagues: Best ball drafts are simple and easy. You don’t have to manage your roster, but you get to experience all the fun and excitement of drafting fantasy teams.
  • Massive Contests, Huge Prizes: The Underdog Fantasy lobby includes massive contests. Right now, one contest has $10M in prizes!
  • Become a millionaire: Underdog Fantasy is making not one but two new millionaires this football season, via Best Ball Mania III. 1st place wins $2M, and 2nd place wins $1M. The entry fee is only $25!
  • Various sports: You don’t just have to play NFL. Underdog also offers contests and props for college football, NBA, college basketball, MLB, PGA, NHL, and more.
  • The best app: Again, there are no hiccups when it comes to the Underdog app. It’s smooth and user-friendly. In many ways, it’s better than industry giants and is just as good as what you find from DraftKings and FanDuel.

More Underdog Fantasy Promotions and Bonuses

Once you sign up using our Underdog Fantasy promo code GRINDERS, you’ll find more promotions and bonuses offered on their app every day. One of the more popular promotions is reduced prop offers, which work similarly to odds boosts and free bets that you see at online sportsbooks.

Basically, by reducing the prop odds, they’ll give you a free prop pick. For example, they may offer Patrick Mahomes over/under 0.5 yards. This is a guaranteed pick that you include in a prop parlay.

Keep in mind, you can only use this type of promotion once per day. In other words, you can’t make multiple prop parlays that include the promotion. Once you use it, it’s no longer available. Luckily there will likely be a similar promotion and offer the next day!

Another promotion users can take advantage of on the Underdog Fantasy app, is by referring their friends to sign up and download the app themselves. By referring friends, you get a $10 bonus for every person that signs up from your referral. Additionally, your referrals get a $10 bonus, in the form of a free entry, to start their account.

You can quickly invite friends and family to join you on the Underdog Fantasy app by sharing your personalized referral link to your group texts and season-long fantasy leagues. You can also compete with your friends in customizable season-long Underdog Fantasy Best Ball leagues.

Of course, make sure to review the terms and conditions of all the promotions and bonuses offered before you use them. There are stipulations that limit how many players you can refer, and there are other details regarding rollover requirements for bonus funds in your account.

Underdog Fantasy began by offering four games for the four major sports NFL, NBA, MLB and NHL. The site didn’t stop there, though. They have since added college sports, including college basketball during March Madness to their game menus.

As far as their contest types go, snake drafts are for season-long, daily, and weekly contests. If you want action on today’s games, you can join 2-6 man contests and start drafting now. Or you can ditch the draft and go straight to Underdog’s Pick’em offerings, called Over/Under & Rivals, allowing you to win as much as 20x your entry.

Underdog’s Pick’em games feature player prop lines and work much like parlays at online sportsbooks. Simply put: The more props you pick, the more you can win.
