The app features three main tabs at the bottom of the screen: “Home,” “Your Bets,” and “Account.” The “Home” tab provides easy access to all available betting markets, neatly sorted by sport or league, with daily promotions and upcoming events also listed at the top of the page.
The “Your Bets” tab conveniently organizes all settled and ongoing wagers, while the “Account” tab offers options for customer support, responsible gaming tools, and other account management features.

Underdog Sports Betting Options – Rating 3/5
Underdog Sportsbook offers a solid selection of betting markets across a wide range of sports and leagues. However, the options are a bit underwhelming when you compare them to those offered by DraftKings, FanDuel, and other leading U.S. sports betting apps.
Here’s a quick breakdown of everything you need to know:
Sports & Leagues Covered
| Sport | Leagues |
| 🏀 Basketball | NBA, NCAAB |
| 🏈 Football | NFL, NCAAF |
| ⚾ Baseball | MLB |
| 🏒 Hockey | NHL |
As you can see in the table above, Underdog Sportsbook currently only accepts wagers on the top 5 or 6 most popular American sports and leagues, such as the NBA, NFL, college basketball/football, and a few others.
You won’t find betting markets for the MLS or international soccer leagues, MMA/boxing, motorsports, golf, tennis, or other emerging sports. However, it’s worth noting that we expect more options to become available as the sportsbook continues to expand its offerings and attract a wider audience.
Types of Bets Offered
When it comes to the different types of bets offered at Underdog Sportsbook, they do a pretty good job of covering their bases. You can choose between moneylines, point spreads, parlays, and all kinds of player props.
For example, in an NBA game alone, you can choose between the basics like points, rebounds, and assists, or dive into more specific player prop bets like first scorer or whether a player will finish with a double-double or triple-double.
That said, I was a bit disappointed to find that Underdog does not currently let you place teaser bets. And it’s also pretty clear that they’re lacking when it comes to game props, alternate lines, and several other popular types of bets.
Safety, Security, & Fairness – Rating 5/5
Safety, security, and fairness are a few of the most important factors to consider when choosing a gambling site or sports betting app. These aspects ensure that your personal information is protected, transactions are secure, and the betting platform operates with integrity.
Fortunately, Underdog Sportsbook excels in these crucial aspects and has earned a perfect 5/5 rating from me and my team. Allow us to explain why:

How Does Underdog Compare to Other Online Sportsbooks?
Now that you’ve learned all about Underdog Sportsbook, are you wondering about how it stacks up against the competition? Well, let’s find out!
Here’s a quick breakdown of how the platform compares to some of the most popular online sportsbooks in the United States today:
DraftKings vs Underdog Sportsbook
DraftKings is one of the biggest names in the American gaming industry, and they offer a comprehensive sports betting platform. While both DraftKings and Underdog are great choices for North Carolina sportsbooks, DraftKings has a few key advantages.
First, DraftKings offers a much larger selection of betting options, especially when it comes to alternate lines. In addition, DraftKings Sportsbook has an edge in terms of their ongoing bonuses for everyday bettors, which include no-sweat bets, odds boosts, same-game parlay insurance, and more!
FanDuel vs Underdog Sportsbook
FanDuel is another top option for online sports betting in the United States, and they are known for their industry-leading mobile app, which provides a seamless and user-friendly betting experience.
In addition, FanDuel Sportsbook takes the lead over Underdog by offering betting markets for a larger number of sports and leagues taking place across the globe, providing bettors with a wider range of options to choose from.
While Underdog Sportsbook offers its own strengths, such as a generous welcome offer and solid customer support, FanDuel’s mobile app and extensive betting markets give it a competitive edge over Underdog and most other online sportsbooks in the U.S.
Caesars vs Underdog Sportsbook
Lastly, Caesars Sportsbook holds an advantage over most sports betting apps with its top-tier customer rewards program and fantastic live betting experience, which provide users with exclusive perks and an immersive way to bet on games as they unfold in real time.
Meanwhile, Underdog Sportsbook stands out as a great option for beginners, offering a user-friendly platform with straightforward betting options and helpful features tailored to newcomers.
Since both platforms have their own unique strengths, the choice will ultimately come down to what you, in particular, are looking for. Fortunately, it seems pretty clear that you can’t go wrong with either option!
