When I started my Underdog Fantasy review, the first thing I noticed was their generous welcome offer for newcomers on the platform. Players signing up for the first time on Underdog Fantasy and making a deposit will receive a deposit match of up to $100.

To claim the welcome offer, all you have to do is sign up on the Underdog Fantasy site and make your first deposit. Once you make your deposit, you will be awarded a bonus of up to $100. I verified that the offer is currently active and is pretty straightforward to claim. You can also check out the Underdog Fantasy bonus review for more details on this bonus.

Also note that you do not need an Underdog Fantasy promo code to claim this bonus, since it is open to all new players on the site.

Signing up on the Underdog Fantasy site – explained in simple steps

During my Underdog Fantasy review, I checked out their sign-up process and found it pretty simple and easy. I have detailed how you can sign up and start taking advantage of the site in the steps below.

In my experience, some of the best DFS betting sites are those that can offer their users a very smooth and pleasant user experience. Doesn’t matter how good their bonuses are; if their website is clunky and navigation is slow, users will not be willing to come back to that DFS betting site.

Fortunately, my Underdog Fantasy Review found the opposite. The brand has a very sophisticated website design with a strong and unique brand identity. I love the bold box callouts for different games and if you like the black and yellow combination as much as I do, then you will love their site design.

Now listen, I am a major dog lover so I am a little biased about the site’s use of a dog in their logo. Full marks for that! Besides that, I found that the games are all well-organized and the navigation is agile and responsive. You will be able to find exactly what you are looking for pretty quickly and seamlessly.

A brief background on the Brooklyn breakout DFS site

As you might have guessed from the title, Underdog Fantasy is based out of Brooklyn, NY and they claim that pretty proudly. I mean hey, I get it. If I was from Brooklyn too, I would make it my whole personality. The company was founded in 2020 during the pandemic era by Trevor John and Brandon Stakenborg. Since then, it has emerged as a prominent competitor to FanDuel fantasy sports and other similar DFS betting sites.

Does Underdog Fantasy have some street cred?

In the DFS betting site market, reputation is everything. This is why I wanted to highlight the market reputation of the brand in my Underdog Fantasy review. Well, I am happy to report that the brand is really putting their money where their mouth is. Word on the street is that the brand is secure, makes good on its bonuses and other reward promises, and is overall a reliable and good DFS betting site that players can trust.

I looked through other non-sponsored expert reviews and player reviews to arrive at this conclusion so you can trust me on this. Besides that, I also didn’t find any red flags or excessively negative player reviews about the site during my review. All of this confirms that the site has a good market reputation and you can play there with confidence.

Player experience on Underdog Fantasy is top-notch

I have very high standards when it comes to rating player experience on any online betting site since it is personally very important to me. I will never log back into my player account on a site if I have an unpleasant experience there. A clunky interface, glitchy site, and slow load times are my absolute worst nightmares and I usually will not tolerate them, no matter how good the bonuses are.

My experience with Underdog Fantasy is quite comparable to my DraftKings daily fantasy sports betting experience. While the latter has been around for a long time, the former is only a few years old, though. Underdog Fantasy offers a seamless player experience both on the desktop version and the app. The login is a one-step process, the navigation is pretty intuitive, and I had no issues finding exactly what I wanted when I wanted it.

Yes, not only does Underdog Fantasy have a mobile app, but they have a GREAT mobile app. I have been in the industry for too long and have seen all kinds of terrible apps. Often online betting sites do not invest enough resources into making their apps look and function well, which I think is a very bad business decision.

In my experience as a player who likes to play on my phone, a good mobile app is key to ensuring I will keep coming back to the site. Underdog Fantasy is undoubtedly one of the best DFS betting apps I have played on. The app interface is very intuitive and I can see that the brand has invested resources to make the app look and feel like a top-notch gaming app.

You can download the app on either the App Store or Google Play Store, which is great since it is available for both iOS and Android users. Side note: the app has a 4.8 rating on the App Store and over 58K reviews, which is a further testament to its popularity.

I feel like this was the only thing about the brand that I was slightly disappointed about. In life, I like options, as I am sure you do too. However, I found the deposit and withdrawal methods on the site to be slightly limited for my taste. Especially because I usually find a much wider selection on other Fantasy Football and Fantasy hockey betting sites alike.

There is nothing I hate more than being stuck on a chatbot, talking to a robot, that understands nothing that I am saying. So I was really glad to see that you can talk to actual humans if you ever need support at Underdog Fantasy.

The brand has multiple support channels which is always a green flag for me. You can either email them at [email protected], call the phone number +1 917-267-2182 to talk to someone in real-time, fill out a web form and request a callback, or simply tweet at them if they are not being responsive.

In my experience, the phone number is a bit of a hit or miss depending on when you are calling but they are super responsive over email.

There is a very complicated licensing process that DFS betting sites have to go through in the United States. So I was not surprised to see that the site is legal in only about 18 states as of now.

However, you can find a very helpful interactive map on the Underdog Fantasy site where you can see which of their games is legal in which states. I highly recommend checking if the game you want to play is legal in your state before you proceed to sign up and make a deposit.

Only available in the United States and Canada

As much as I would like Underdog Fantasy to have international fame, it hasn’t gotten there yet, much like US football (but don’t tell them I said that). So for now, you can only play on the site if you are a legal resident of the 18 states in the United States where the site is legally available and most Canadian provinces, except Ontario. Once again, check the map on their homepage to find out which game is legal and where.

Unlike some of the other DFS betting sites, Underdog Fantasy doesn’t have a fully built-out loyalty program or VIP program. However, they do incentivize customer referrals by rewarding players with $10 in site credit if they can bring a new user onto the platform who deposits at least $10 and plays a game at least once. In my opinion, this site could do more, but I am hoping that as and when they grow, they will offer better loyalty program options.
