Underdog Fantasy Sportsbook Review 2025

We started off our review by signing up to Underdog Fantasy and were instantly greeted with a special welcome bonus that makes getting started feel easy and rewarding. Right now, new players can take advantage of a straightforward deal: Play $5 and Get $100 in Bonus Entries. 

The process is really simple. Just create your account, make your first play of at least $5, and Underdog Fantasy will credit you with a $100 in bonus entries. This will give you plenty of extra credit to dive into fantasy contests and see what the platform is all about. It is a clean, no-frills offer that makes it easy to get more from your very first play.

Of course, there are a few important details to keep in mind. You must be at least 18 years old to take part (19+ in Alabama and Nebraska; 19+ in Colorado for some games; and 21+ in Arizona, Massachusetts, and Virginia). The offer is not available in Maryland, Michigan, New York, New Jersey, Ohio, or Pennsylvania, and you must be physically located in a state where Underdog Fantasy operates to claim it.

We like how this bonus cuts through the noise with a simple bonus offer; play just $5, and get an extra $100 in bonus entries to enjoy. Just remember that the bonus itself is not withdrawable, but any winnings you get from playing with it are yours to cash out. That makes it a great introduction to what Underdog Fantasy has to offer without overcomplicating things.

You can play fantasy sports at Underdog Fantasy either from your computer via the browser or through your mobile on the iOS and Android apps. All of the platforms benefit from the same stylish gray and yellow color scheme, and we found that the interfaces were fast enough to keep up with our demands.

Just like amwager betting site, Signing up is a pretty easy process as you just have to hit the green Sign Up button and then fill in the registration form with your relevant details. From here you can simply enter in any promo codes, make your opening deposit and receive your welcome bonus.

It’s also nicely easy to browse all of the available contests and you’ll be able to see all of the important information like prize pools and so on. Assembling your fantasy sports team is also very simple and you’ll be able to go through the draft process easily enough while staying within your salary cap.

Above all, Underdog Fantasy gives you a supremely user-friendly fantasy sports experience. It’s kind of the polar opposite of what you receive with some other fantasy sports providers where you have to endlessly tinker with your team line-up to account for things like injuries and so on. Instead, at Underdog Fantasy you can simply create your squad, enter them into the tournaments and then see if you have won anything at the end.

We found that it was quick and easy to make payments at Underdog Fantasy. You will be able to use all of your favorite credit card providers here and there is also the option of using PayPal. What’s best was the fact that all of our deposits went through quickly and we weren’t charged any deposit fees.

It was a similar picture for making withdrawals of whatever winnings we’d made. Here you just have to make a withdrawal request of $10 or more and you should find that the payment should be made in just a few working days.

Bear in mind that Underdog Fantasy pays out fastest for PayPal withdrawals, but you won’t be hit with any charges for requesting a payout from this fantasy sports site. All of which shows that you can trust Underdog Fantasy for making deposits and withdrawals.

Nobody likes to experience bad customer support and this is something that you won’t have to suffer at Underdog Fantasy. This is because we found that the brand features a friendly and knowledgeable customer support team who are always waiting to hear from you.

We found that we just had to tap the little question mark icon in the bottom right of the Underdog Fantasy homepage and it brought up a handy live chat dialogue box. This gave us a simple way to put our questions to one of the customer support team and there was even the option of uploading some documents like screenshots and so on.

Beyond this, we saw that Underdog Fantasy features a dedicated customer support email address although we didn’t see any kind of telephone support. We should note that Underdog Fantasy is very active on social media and so it might be worth keeping in touch via Twitter, Facebook, Instagram or Discord. Plus there’s even an Underdog Network that acts as a kind of blog to help you out with the latest sports news.

Finally, we should note that while customer support is available 24/7 at Underdog Fantasy, a very useful FAQ is also available. This provides detailed information on topics such as tournament operations, withdrawal procedures, and more. All of which should give you a good start at this fantasy sports site. If you are experiencing concerns related to your gambling activities, we recommend contacting 1-800-GAMBLER or visiting www.ncpgambling.org for assistance and guidance. New York players can call the 24/7 HOPEline at 1-877-8-HOPENY or text HOPENY (467369). Please note that terms and conditions apply. For full details, you can view the terms and conditions.

We can’t really have an Underdog Fantasy sportsbook review without examining which US states this brand is legal in. First of all, Underdog Fantasy is a legit fantasy sports provider and it is allowed to operate in many different US states. The only complicating matter is the fact that some of the fantasy sports tournaments might be available in some US states and not others.

For example, you can’t play at Underdog Fantasy in about a dozen US states including Washington, Connecticut and Michigan. Then the Underdog Fantasy Pick’em contests aren’t available in certain states like Colorado, Iowa and Tennessee. All of which means that you should look through the Underdog Fantasy terms and conditions to see which contests you can play in your state of residence.

All other trust features of the Underdog Fantasy site are as we’d expect. This means that there’s a privacy policy explaining how the operator will handle your data at this fully encrypted site. Plus, it’s nice to see that there are even some responsible gambling tools available, even though Underdog Fantasy doesn’t really offer a traditional kind of gambling. This shows that Underdog Fantasy is a fantasy sports provider that you can trust.

There is no reward program at the Underdog Fantasy site. Such a move may not be hugely surprising given that reward programs tend to feature more at regular sportsbooks than fantasy sports providers.

However, we have to remember that Underdog Fantasy has put on a great welcome offer and so it’s a little strange that it doesn’t have any similar deals for existing customers. Hopefully, this is just a temporary measure and that Underdog Fantasy will introduce some kind of reward program in the near future. So watch this space to see when Underdog Fantasy finally puts on some decent promos for its loyal customers.
