What will you get with the Underdog Sports promo code?

The Underdog Sports promo code offers a deposit match bonus of up to $100 in promo credits. To qualify, participants must deposit a minimum of $10.

The Underdog Sports promo code credits are equal to the amount of the first deposit, up to a maximum of $100. However, it’s important to note that both the deposit and bonus amount must be played through before they can be withdrawn. This means that the total amount of the Underdog offer must be used to enter contests and play games on the Underdog Fantasy platform.

If a participant receives a deposit bonus, the entire deposit and bonus amount must be played through before any winnings can be withdrawn. Any refunds are returned in the same type of funds used for the contest entry. For example, if a $10 entry uses half bonus funds and half withdrawable funds, users will be refunded $5 of bonus funds and $5 of withdrawable funds.

Underdog Fantasy also offers a money-back guarantee for new users. To qualify, participants must meet the following conditions: the refund is offered on the first contest, the participant must be dissatisfied with the product or experience, the participant must close out their account to receive the refund, and the refund is up to $100. Participants must claim the refund within 48 hours of entering the contest.

Why Should You Choose to Play With Underdog?

Underdog Fantasy stands out as a premier destination for daily fantasy sports (DFS) enthusiasts for several compelling reasons. Unlike traditional DFS platforms, Underdog Fantasy offers a refreshing take on the genre, catering to a broader audience, including casual players. Here’s why DFS fans should consider using Underdog Fantasy:

Unique Contest Formats

Underdog Fantasy offers a variety of contest formats that set it apart from traditional DFS sites. One of its most popular formats is the snake draft, where players take turns selecting players for their fantasy team. This adds an exciting element of strategy and interaction among participants.

Smaller Contests

Underdog Fantasy focuses on smaller contests, which means players have a better chance of winning compared to larger, more competitive contests on other platforms. This makes it an ideal choice for casual players or those looking for a more relaxed DFS experience.

No Professionals

Underdog Fantasy does not allow professional players or “sharks” to participate in its contests. This ensures a level playing field for all participants and makes it more accessible to casual players who may be intimidated by the presence of professional competitors on other platforms.

User-Friendly Interface

Underdog Fantasy’s platform is designed with the user in mind, featuring an intuitive interface that makes it easy to navigate and participate in contests. This makes it an excellent choice for beginners or those new to DFS.

Wide Range of Sports

Underdog Fantasy offers contests for a wide range of sports, including football, basketball, baseball, hockey, and more. This variety allows players to participate in contests for their favorite sports and diversify their DFS experience.

Generous Promotions

Underdog Fantasy frequently offers generous promotions and bonuses to new and existing players. This includes the current Underdog Fantasy promo code offer of up to a $100 bonus match, an excellent incentive for players to sign up and try the platform.

Underdog Promotions for Existing Players

Underdog Fantasy offers a variety of promotions and bonuses that provide ongoing value for players beyond the initial welcome offer. These not only incentivize new users to join the platform but also reward existing players for their loyalty and engagement.

Refer a Friend

Underdog Fantasy offers a “Refer a Friend” program where existing users can earn a $10 credit to their account for each friend they refer who successfully deposits at least $10 on the platform. To qualify, the referred friend must enter the referrer’s username as their referral code during the registration process.

The $10 credit is awarded to the referrer’s account once the referred friend makes their deposit. However, the referrer cannot withdraw the site credit until it has been used to play in a game on the Underdog platform.

Multiplier Boosts

Underdog Fantasy offers Multiplier Boosts, which are special promotions that increase the potential winnings for certain contests. Any Pick’em multiplier winnings over the standard multiplier will be awarded as bonus cash.

This bonus cash must be played through (1x) before it can be withdrawn. Similarly, for Pick’em Specials, where the payouts are normal but a heavily-adjusted, user-friendly projection is included in an entry, any winnings over the previous level (e.g., Pick 5 to Pick 4) will be considered bonus cash and must be played through (1x) before it can be withdrawn.


Underdog Fantasy also hosts Sweepstakes, which are special promotions featuring a single player and specific stat projections. When a customer makes a Pick ’em entry that includes one of these picks, they enter into the promotion according to the terms of that specific sweepstakes.

Sweepstakes have their own section in the sidebar menu of the Underdog Fantasy website. It’s important to note that Sweepstakes are void where prohibited, and customers should review the individual sweepstakes rules for details.

Underdog Fantasy Best Ball

Underdog Fantasy offers a unique and exciting Best Ball game format that is perfect for both casual and experienced fantasy sports players. In Best Ball, contestants draft a team just like they would in a regular season-long NFL fantasy football league.

However, unlike traditional leagues, there are no roster movements throughout the year. This format offers a fresh and engaging experience, with strategies centered around position allocation and roster formation.

In Best Ball on Underdog Fantasy, each team is given a specific roster that they must fill through the draft. Once the draft is complete, points are accumulated on a game-by-game basis from specific positions. This allows players to focus on drafting a strong team without the need for constant roster management.

One of the most popular Underdog Best Ball tournaments is Best Ball Mania. This is the largest of Underdog’s yearly NFL Best Ball competitions, offering huge prizes ($15 million in the 2023 contest) and a chance to compete against thousands of other players. Best Ball Mania is a highly anticipated event that attracts fantasy sports enthusiasts from around the world.

In addition to Best Ball, Underdog Fantasy also offers Pick’em contests and Sweepstakes. Pick’em contests allow players to make predictions on specific game outcomes, while Sweepstakes offer a chance to win prizes based on specific player performances in underdog contests. These additional game options provide even more opportunities for players to engage with the platform and enjoy the thrill of fantasy sports.

Underdog Best Ball tournaments

Underdog’s best ball game options offer a unique and exciting twist on traditional fantasy sports. In best ball leagues, you draft a season-long roster of players, but you don’t have to worry about setting lineups each week. Instead, your team’s score is automatically calculated based on the best performers from your roster each week.

This format allows you to focus on the draft and enjoy the season without the hassle of managing your lineup every week. With Underdog’s best ball game options, you can compete against friends or join public leagues to test your skills and see if you have what it takes to build a championship-winning roster.

Best Ball Mania IV: $15M in Prizes

Underdog’s flagship Best Ball Mania tournament is a premier event in the world of fantasy sports. It offers a total prize pool of $15 million ($3 million to the winner), making it one of the largest best ball tournaments in the industry.

The tournament typically features buy-ins of $25, making it accessible to fantasy enthusiasts of all levels. Best Ball Mania spans the entire NFL season, allowing participants to enjoy the excitement of fantasy football from the kickoff in September to the final whistle in February. With its massive prize pool, affordable buy-ins, and season-long format, Best Ball Mania is a must-play event for any fantasy football fan.

Unlike traditional Best Ball leagues that span the regular NFL season, these contests focus exclusively on the NFL postseason. Entry fees for these contests tend to be higher than regular season best ball leagues, reflecting the increased stakes and potential rewards.

In NFL Playoff Best Ball contests, rosters lock at the start of the NFL playoffs and remain unchanged throughout the postseason. This format adds an extra layer of strategy, as participants must carefully select players who they believe will perform well in the playoffs.

Prizes in NFL Playoff Best Ball contests are typically awarded to the top finishers, with larger payouts for those who finish higher in the standings. Additionally, some contests may offer the opportunity to qualify for live final events, where participants can compete for even bigger prizes and the chance to be crowned a fantasy football champion.

When will Underdog Sportsbook Launch?

Underdog Fantasy has plans to expand its offerings by launching an online sportsbook in several states. Most recently, Underdog NC launched with North Carolina online sports betting in March of 2024.

The company is working diligently to secure the necessary licenses and approvals to bring its sportsbook to these states. Once the sportsbook is launched in these states, users will be able to enjoy a wide range of legal sports betting options, including traditional sports betting, live betting and more.

Battle Royale: Underdog Fantasy DFS

One unique game format offered by Underdog Fantasy is Battle Royale. This combines traditional DFS snake drafts with survivor pool concepts for an exciting twist.

Here’s how Battle Royale works:

  • Each week, there is a new contest with 10-20 players
  • You draft nine players to your team under a salary cap
  • Your roster must include one player from each of three designated game slates (Thurs, Sun Early, Sun Late)
  • Points accumulate each week your players are active
  • You can swap out players between slates as games start
  • The lowest-scoring team each week is eliminated
  • Play continues until one champion remains after all teams are eliminated

The Battle Royale challenges players to balance drafting top scorers with value plays to survive each week. It adds a survivor pool element where you want your team to avoid being the lowest scorer who gets knocked out.

The contests typically run 5-7 weeks to crown a final champion. The tournaments offer large prize pools, often starting with a $20 entry fee and thousands in prizes.

Battle Royale is a unique DFS game that’s exclusive to Underdog Fantasy. It’s a fun alternative to its standard snake draft contests and is growing quickly in popularity.
