The name Underdog is quite fitting for this steady DFS site that has been lowkey floating under the radar since its inception in 2020. My Underdog review made some interesting revelations that I’m happy to share.
Underdog picked a niche and is emerging as the go-to DFS site for Best Ball tourneys. That’s not to say this is all it has to offer. Exciting snake draft competitions and Pick’em games are all part of the fun. Join me as I discuss everything Underdog has to offer, from bonuses and payments to usability.

Bonus Offer – A nice headstart for new fantasy sports players
New users are ushered in with a cool match deposit Underdog bonus to kick off play. You must enter a promo code to activate the welcome bonus successfully. Seeing as this is a global brand, the exact deposit amount differs from one location to the next.
Underdog also has a ‘Play $5, Get $50 in Fantasy Bonus Entries‘ offer for its players. All you need to do is make a deposit and place a $5 play, and you’ll receive fantasy bonus entries worth $50 for use on your favourite fantasy contests!
My Underdog review can confirm that it’s not a no deposit bonus. You’ll have to make a small deposit to unlock it, which is pretty standard with deposit match deals. Note, however, that you only receive the bonus once you satisfy a few conditions. I wouldn’t say this is unreasonable, although some brands automatically credit your account with the bonus soon after your deposit. You must then play the bonus and deposit once before claiming any winnings.
To claim the offer, you must be at least 18 years old, except in Alabama and Nebraska where you must be 19, in Colorado where some games require you to be 19, and in Arizona, Massachusetts, and Virginia where you must be 21. You must also be located in a state where Underdog operates. This offer is not available in Maryland, Michigan, New Jersey, New York, Ohio, or Pennsylvania. Terms apply.

Usability, Look & Feel – Highly intuitive interface
When you talk of intuitive websites, Underdog is right up there with the best. I don’t take too kindly to clunky sites with over-the-top frills, no matter how amazing the bonuses are. That’s why I appreciate Underdog’s streamlined layout, which is pretty straightforward. Information is displayed logically, making it simple for even the first-timers to figure out what’s what and get started. For instance, it’s easy to browse through the different fantasy sports and tournaments. Also, when deciding on a contest, you get a quick rundown of the contest rules and information.
Testing the site for my Underdog review, I found creating an account easy using the simple four-step procedure. You’ll need to submit the last four digits of your SSN for verification purposes as you complete the Underdog register process, so don’t freak out. In terms of speeds, the site is no snail. Pages load ever so quickly, making it a real pleasure to navigate the site. One thing to note, though, is the site uses geolocation software. You can only access the operator from an approved location.
Moving on to aesthetics, the hints of yellow against a black backdrop make for a catchy outlook. I like how you can customize the site to a dark or light theme, depending on your preference.
Underdog App – Lightweight software
The seamless usability I experienced on the operator’s desktop extends to the mobile space. My Underdog reviews picked up on a dedicated mobile app, which skyrocketed the brand’s ratings. It’s a great app that’s lightweight and practical. You download it from the App Store or the Google Play Store. You only have to look at the app’s 4.5 and 4.9 ratings on the Google Play Store and App Store to understand that no bias is going on here. Over 250,000 Apple users have good things to say about it.
Performance-wise, I had no issues with both apps. Sports are organized according to their different types. It’s easy to enter tournaments by simply browsing through the options displayed on the tab. As with the desktop, if you choose a contest, all its info is immediately displayed. You can see all sorts of stats, such as what competitions are on offer and how much it is to enter. There is even info on how much Underdog takes for each contest.
Payments – No hidden costs
I’ll admit that Underdog doesn’t have the longest list of payment methods. My Underdog review found a handful of reliable ways to fund your account. For deposits, you can use debit or credit cards such as Visa, Mastercard, Amex, and Discover, or go with PayPal, Trustly, or Venmo.
Withdrawals offer a few more options than you might expect, with PayPal, Trustly, Paysafe, and Interchecks all available. Interchecks is particularly flexible, giving you the choice of a bank transfer, physical check, or e-check.
I’ll give Underdog credit for sticking to reputable, well-known options. PayPal remains the most widely used digital wallet around, and Visa and Mastercard are as dependable as ever for straightforward card payments.
Deposits are instant, so you can get into your first contest straight away. Withdrawals take a little longer, typically processed within 48 to 72 hours, though Trustly bank transfers may take an additional 1 to 3 business days depending on your bank. There are no transaction fees on either end, which is always a welcome bonus. The minimum deposit is $10, and with entry fees starting from as little as $5, it remains accessible for all types of players
Customer Service – 24/7 support
Should you run into a few hurdles on the site, trust the Underdog support team to bail you out. It has a support team open around the clock for your convenience. I like the live chat because it delivers the fastest responses. Plus, you interact with a human for a personalized feel. Also, feedback is well-thought-out and thorough.
I’m not a fan of emails but I tested the option out for the sake of my Underdog review and was pleasantly surprised. You forward your query directly from the website via the on-screen contact form. The response came within a few hours and it was quite detailed. I’ve seen too many DFS sites only respond the following day. I found the FAQ section quite insightful. It addresses several questions on registration and the like that DFS first-timers would like to know.

License & Security – Underdog is legit
My Underdog reviews can confirm that this is a legitimate site with operations in the US and Canada. It is available in 41 states for drafts. However, Pick’em and Champions are both available only in certain states. Luckily for you, they have a handy infographic on the front page of the site that gives you a breakdown of what is available in your specific state. Furthermore, Underdog is available in all of Canada except Ontario and follows the regulations of each province and state where it is found.
There are other tell-tale signs that speak to the brand’s credibility and confirm that Underdog is legit. For one, it’s endorsed by top celebrities like Kevin Durant and has a transparent customer support system. The site is also SSL-encrypted to safeguard your details. Moreover, the app has 2FA and biometric Underdog login as an additional layer of security.
Rewards & Loyalty Program – Refer a friend and receive $10
I can’t quite grasp my head around the fact that my Underdog review didn’t spot a loyalty program. One would expect a site that’s been around since 2020 to have one in place. However, the operator does reward its loyal players in other ways. Probably the biggest way to get extra bonuses is through customer referrals. It’s a straightforward scheme where you get $10 for each friend you refer to join the site. However, your buddies must deposit at least ten bucks and play it once for the bonus to hit your account.
Other than that, you can take advantage of a handful of promos such as multiplier and Pick’em boosts. These certainly made a difference in my play, letting me cash out bigger payouts. And the fact that I got these winnings as fantasy bonus entries after I only had to play once.
| 🎁 Bonus Type | ✍️ Details | ✅ Eligibility |
|---|---|---|
| Welcome Bonus | Play $5 get $50 in bonus fantasy entries | New users only. Minimum deposit, entry and 1x playthrough requirement apply. |
| Refer-a-Friend | $10 fantasy bonus entry per successful referral | Friend must deposit and play $10 in bonus entires before bonus is credited. |
| Pick’em Boosts | Occasional boosted multipliers during Pick’em contests | Available to registered players, but will vary for each event and region. |
| Seasonal Promos | Limited-time events, boosted payouts, or gimmie entries | Check the promo page or app notifications for current offers. |
Offer – Specialists in draft competitions
For the most part, Underdog follows the general DFS operating model. Players sign up, draft players, and enter them into competitions. As unearthed by the Underdog review, players get points based on how the athletes perform in real life. Where the site does things slightly differently is by focusing more on drafts than salary caps with its Pick’em contests. Simply predict if your team will wind up with a higher score than the predicted score.
However, you can also participate in Battle Royale, although this is only for the NFL. You pick a team through a snake draft with no salary cap. It’s quite easy to draft players on the site. A feature l found helpful was the ability to create my shortlist of players and add them to a “favorites” list.
Let’s just say this made it ten times easier to draft players. Best Ball games are its strong suit. When you’ve selected your players for your Best Ball roster games, the system automatically picks the best-performing athletes as starters at the end of each week. This ensures you always have the best lineup of players at any given time.
Prize Pools – Flexible buy-ins
My Underdog review found that this DFS site boasts having one of the most rewarding fantasy contests. The Best Ball Mania Tournament alone had a $3.5 million prize pool, with one million awarded to the main prize winner. Information on what the contests are about and how to enter is displayed, proving the operator’s commitment to transparency.
What’s interesting is that you don’t need to spend an arm and a leg to enter some of the contests. The prize pools vary, depending on the contest. However, smaller entry fees usually equate to smaller prize pools. For example, some contests like the Zamboni have entry fees of as little as $5.
And just like that, you’re in the running for a share of the $100,000 prize pool. Others with million-dollar prize pools require a buy-in of $25. Basically, you align with what you can afford. My Underdog review also noted how Pick’em contests don’t have prize pools. Winners can walk away with up to 20x their stake.
Community – Visit the Underground Network
Underdog is pretty big on socials, especially X. According to my Underdog review, it also has a visible presence on Facebook and Instagram. Simply follow the brand and engage with other players on these pages.
I also made some friends and interacted with like-minded players on community forums like Reddit and Discord. But where the site excels is by curating what it dubs the Underdog Network. This is your go-to for all your up-to-the-minute sports news to help with your Daily Fantasy Sports picks. I also found insightful blogs there. I may not have been able to communicate with other players there, but I sure learned a lot.
Conclusion – Enjoy DFS with no complications
Rounding up my Underdog reviews, this is by far the best site to join if you want to have a go at DFS, minus any hassles. The site doesn’t have that many DFS sports, so it won’t overwhelm newbies. Since it eases up on the daily salary cap competitions, Underdog is great for players who are not yet ready to mingle with sharks.
Underdog offers the best in Pick’em games and Best Ball games with reasonable payouts and impressive prize pools. You’re at liberty to enter a contest that resonates with your skillsets, preferences, and of course bankroll. That said, it definitely has my vote.
