Is Underdog available in your state?

Check out our table below to see if Underdog is available in your state and also be on the lookout for your state-exclusive promo code so you can start enjoying their welcome offer today:

In the same vein as our ParlayPlay review, you’ll find that Underdog leaves a memorable first impression with its understated, yet classy, online interface. The mere fact that you can create an account within a couple of minutes via the streamlined website is a great start. We also like the overall design of the site and the fact that it’s so easy to find what you are looking for.

In the same breath, it’s clear that the site is serious about providing a high-end gaming experience. The site performs incredibly well while all commands and betting features work effectively to facilitate a very enjoyable betting adventure.

Creating an account with Underdog

1. Simply click on the link and hit the Sign Up button.
2. Fill in all of your personal information and accept the terms and conditions.
3. Verify your email and provide proof of identity.
4. Log in, make a deposit, and claim the Underdog promo code.

Once you have done this, you can utilize the extensive betting opportunities by partaking in the multitude of fantasy sports leagues that are offered.

There are plenty of DFS operators that have entered the US market in recent years. Some of these sites have created mobile apps that not only complement the desktop sites, but provide an entirely new dimension to your betting experience. Our Underdog review is no different in this regard as you’ll be able to download the latest app for your fantasy betting.

The dedicated app is available on Apple and Android devices. It doesn’t require the latest software updates and only takes up a small amount of storage on any given device. It has all of the same betting tools; covers the same number of leagues; and includes the extensive contests found on the desktop platform. Plus, you can access your account using your mobile web browser without having to download the app.

Is Underdog legit when it comes to payments? It’s an important question and one we have the answer to. If you make use of this platform, then you’ll be able to deposit funds using any major credit card as well as PayPal. As long as the account is in your name, you’ll be free to deposit a minimum of $10 instantly into your account (once your profile is verified).

Withdrawals include the same payment methods as outlined above. Withdrawing using the same method is advised as this tends to speed up the process of withdrawal requests by some time.

The customer support provided to players in the US is certainly deemed to be somewhat limited in terms of options. This platform doesn’t have a live chat feature and the general FAQ section isn’t as extensive as we’d hoped for. Having said this, you will still be able to lean on the email support feature at all hours of the day. Simply fill in the online form by clicking on the ‘Help’ tab, and you’ll receive a response via email as soon as possible. It can take anywhere between a couple of hours and a day for the team to get back to you.

If you are wondering, ‘is Underdog legal in California’ as well as other states in the US, then look no further. The site has created a reputable name for itself across the country. It’s available in all states except ​nine (check the website for the full list or try access the platform from your current location). Plus, the operator uses the latest SSL technology which allows it to monitor all data on the site.

So, is Underdog legit? It’s evident that this platform is a legitimate DFS site that also has comprehensive security protocols in place so that all of your personal info and real cash funds are protected.

As part of our Underdog review, we’ve run through the additional rewards that are offered by the platform. Unlike our Draftkings Fantasy Review, a fully-fledged VIP experience is absent on the site. This shouldn’t impact your decision too much though.

For instance, you can get your friends involved and claim a $10 referral bonus if they sign up and follow the terms of the offer. Secondly, there tend to be boosts offered on Pick’em games where you can increase potential cash winnings considerably.

Lastly, there’s a ‘money back’ offer if you come to find that you don’t enjoy the platform. Of course, terms apply, but you can get up to $100 back as the platform says. Plus, you follow one or several of their social media channels as there are bound to be promotions offered that you’ll otherwise be unawares of.
