Underdog Fantasy has been a known quantity for some time in the DFS space, offering legal pick'em fantasy games in 33 states. It has a remarkable roster of investors, including Odell Beckham Jr., Future, Mark Cuban, and Kevin Durant.

However, its operator will introduce sports wagering to its offering for bettors in legal betting states. It holds a sports betting license in Ohio and North Carolina to offer wagers on sports action.

In this review, we'll examine this operator, one of the up-and-coming US sports betting sites on the market. We'll examine its betting markets, customer support, the Underdog mobile app, and everything else you'll need to know before signing up for this sportsbook.

1: Welcome Bonus


How to claim the Underdog welcome bonus

For its DFS platform, Underdog Fantasy provides a $100 deposit match bonus, and once sports wagering is in operation, it could decide to extend this offer to bettors. With a deposit match, when you make your first deposit, your sportsbook will match the value of your funds with bonus bets.

The welcome offer gives you site credit, which you can use these bonus bets to place wagers on the Underdog app or desktop client. First-time users receive a great welcome offer when beginning their wagering journey with Underdog. In my experience, the Underdog promo code is good value, especially in the DFS space, so I would expect its sportsbook bonus to be equally valuable.

How the Underdog Welcome Bonus Works

The Underdog promo code works as a deposit match. This means that whatever the value of your first deposit, when new customers use the promo code, they'll receive bet credits equal to the value of the deposit, up to $100. These bet credits are then able to be used on the online sportsbook. This type of bonus is a really common promo code for bettors who complete the registration process.

Important Bonus Terms & Conditions

Underdog gives a welcoming Fantasy Deposit Match Bonus to new users, matching first deposits up to $100 in credits when you use the operator's promo codes. However, there are a couple of terms and conditions that you'll need to be aware of before accessing this offer.

  • To be eligible, participants must make a minimum initial deposit of $10.
  • There is a 1x playthrough on the bonus.
  • The promo code bonus amount must be used within sixty days.
  • There may be some restrictions on the types of wagers eligible for use with the bonus bet, including restrictions on same game parlays and odds boosts.


2: Other Promos & Loyalty Programs

Promotions for Existing Users

Underdog's sportsbook promo codes for existing customers are a testament to their commitment to keeping the betting experience fresh and rewarding. Having explored their offerings extensively, I've seen firsthand how these promotions add value and excitement to the experience. Below, I'll share insights into some of the standout promotions that keep me and fellow sports fans engaged.

Refer-a-Friend Program: Underdog’s Refer-a-Friend initiative is a simple yet effective way to earn extra credit. By inviting friends to join and make a qualifying deposit of $10 using my referral code, I earn a $10 credit per friend.

Boosts/Specials: Odds Boosts can significantly increase your winnings. Underdog provides a boost on top major league, such as NFL bonuses, and collegiate sports. On its pick'em contests, the additional winnings are given as bonus cash, requiring a 1x playthrough, which is worth noting.

Make sure you check this page for the latest bonus news, regular betting news and promotions from Underdog and all the top US gambling sites.

Rewards Program

Underdog Fantasy does not currently have a rewards program for its members. This is disappointing, as rewards programs are commonplace at top US sportsbooks. For instance, Caesars Rewards at Caesars Sportsbook offers regular bettors perks like comped meals and air travel.

I hope that Underdog Sportsbook Ohio and North Carolina offer this in the future, as it would help the Underdog website be among the best for US bettors.


3: Sportsbook Features & Betting Options

Unique Sportsbook Features

One of the more interesting key features of the platform is the Underdog Network, a blog with expert opinions on major league and college sports. It features written content and shows with analysis of NFL and basketball games, tailored towards helping bettors hone their wagering strategy.

I really enjoyed the Underdog Originals, which are long-form documentaries on US sports. While this isn't really a feature of the sportsbook, I haven't really seen an operator commit this much to offering additional content. It's a really big plus for the platform.

Another really innovative and unique initiative of Underdog's is its Guard Dog Responsible Gaming Innovation Fund. The fund is aimed at aiding the development tools dedicated to safer fantasy sports and betting experiences.

It offers financial backing for innovative safer gambling tools, essential introductions to leading investors, and a fast track into the Underdog platform. With guidance from esteemed mentors like former FanDuel VP of Responsible Gambling, Adam Warrington, Guard Dog champions innovation in creating a secure and enjoyable environment for all players.

To keep up with the best betting sites, Underdog will also offer a comprehensive live betting markets on its sportsbook and the Underdog app, allowing bettors to take advantage of shifts in the action and keep engaged with the action.

Offering a robust live betting experience would allow the platform to keep up with major operators like FanDuel and DraftKings. Equally, I'd like to see live streaming added to allow bettors to watch the action as they bet through the Underdog Sportsbook app. Overall, the features at Underdog are unique, innovative, and make signing up for this sportsbook well worth it.

Available Sports & Betting Options at Underdog Sportsbook

Underdog Sporsbook currently offers a couple of sports for fantasy contests, and we anticipate that the offering will increase significantly when the site begins offering wagering, including major leagues and collegiate sports, like NFL betting, MLB betting, and other popular leagues like NBA and NHL. To keep up with the best US betting sites, Underdog could also offer some niche offerings, like badminton, rugby, and cricket.

Best Underdog Sports Betting Options

  • Moneyline: The simplest bet type, Moneylines involve bettors predicting the outcome of an event. Variations include two-way and three-way moneylines like in NHL Betting. The former includes any overtime, and the latter includes a tie at the final alongside a win for either side.
  • Spread betting: With a point spread, Underdog will apply a handicap to the favorite. For your bet to pay out, you must accurately predict the outcome of the event after the handicap has been applied to the final score. For instance in Super Bowl betting sites, a spread will be offered and one of the teams will be given an advantage over the other at the start of the matchup.
  • Totals: Totals, otherwise known as over/under, involve you predicting the total score of both sides. Underdog will set a betting line, and you must wager on whether the final total score will be above or below this line. This can be found on college basketball betting, where the sportsbook will set a total amount of points and you can bet whether the total points in a match would be over or under that set amount.
  • Props: Proposition bets, known as props, are wagers placed on statistics of individual players or teams, for instance, how many passing yards a team will complete or whether a player will score over or under a preset amount of points in NBA Betting. You might find special bonus bets on props throughout the season.
  • Parlays: Parlays are combinations of wagers in a single bet slip. For a parlay to pay out, every selection you make must be accurate. This can be found in many sports such as college football betting.



4: Website & App UX

As an experienced user, I've found their platform to be intuitive, making it easy for new customers to navigate through sportsbook promos, regular betting news, and promotions. The Underdog mobile app, available for iOS and Android, mirrors the website's functionality, allowing users to engage with the sportsbook's offerings and markets.

From placing wagers to placing player prop pick 'em cards, the app provides a comprehensive live betting experience. The Underdog fantasy app is rated highly by players, with iOS users giving it good very good ratings.

Underdog's website stands out for its user-centric design and functionality, ensuring a smooth transition for users familiar with its application. The platform emphasizes ease of use, offering essential features that enhance the betting experience for both seasoned and new bettors alike.

With intuitive navigation, users can effortlessly access sportsbook promos, stay updated with regular betting news, and manage their accounts with ease.

The website's design also supports users in making informed decisions through accessible tips and tools without overwhelming them with unnecessary complexity. The website and mobile UX's user-friendly interface make Underdog stand out as one of the best betting apps

7. Security & Customer Support

Underdog Sportsbook Customer Support

Underdog Fantasy suffers from a drawback, which is limited support for customers. The site doesn't offer phone support or live chat but instead funnels most of its troubleshooting services down the social media line.

This is quite common for smaller DFS operators, but is frustrating if you want to speak to a representative. We did like the Discord support, which was hassle-free to join and featured a community including players and customer service agents.

When Underdog Fantasy launches its legal sportsbook, we'd like to see a greater range of more traditional customer support options, however.

Is Underdog Fantasy a Sportsbook?

While Underdog is expanding into sports wagering in NC and OH, its original product, Underdog Fantasy, remains distinct from a traditional sportsbook. It specializes in pick'em fantasy contests across major sports leagues. Here, players predict if athletes will surpass or fall short of specific performance benchmarks. Combining multiple picks into a parlay can significantly increase potential returns.

Despite this, wagering is now being offered at Underdog, thanks to its legal Underdog Ohio Sportsbook and NC platform. While the operator won't be offering some of the features of larger players in the industry, like a retail sportsbook, it will offer legal betting markets on a number of popular sports and leagues across the United States and beyond for sports fans.

Is Underdog Sportsbook Legit and Safe?

Yes, Underdog's Sportsbook reputation is sterling, and the site is safe and legal. It is fully licensed to offer sports wagering in Ohio and North Carolina (where it is expected to be one of the March Madness betting sites in the state) and is operational in 33 states for DFS. Players on its Underdog Fantasy and Sportsbook can make deposits and withdrawals securely thanks to the site's payment protection systems, like SSL encryption and reputable deposit methods.

8. Final Verdict


Final Verdict

As one of the new betting sites, Underdog is set to make a significant impact in the legal sports betting market of Ohio and North Carolina, leveraging its established presence in the DFS arena. Backed by notable figures like Odell Beckham Jr. and Mark Cuban, it's poised to offer a rich betting experience highlighted by its highly rated mobile application, secure banking options, various promotions for new and existing bettors, and solid customer support.

While specifics on the Underdog promo code are yet to be confirmed, the DFS bonus is good for the space, and I expect the site to offer certain promotions of significant value to new customers. Underdog sports wagering platform, with its commitment to responsible gaming and innovative features, is on track to become a standout choice for bettors in the US online wagering landscape.
