Underdog Fantasy reigns in the NBA, which is going on right now with playoffs rapidly approaching. Users can also make picks on the MLB and NHL with the WNBA right around the corner.

The Underdog app has something for everyone, and can be used in most states (there’s even Underdog Fantasy California, a state that has notoriously banned sports betting)! From Best Ball, daily snake drafts, and DFS Pick’em to a new peer-to-peer format, there are multiple ways to use our Underdog promo code.

Sign up today with Underdog promo code to dive into these contests and enjoy the action with the RotoGrinders team. I used the info below to register and , plus a free special pick on one of the best fantasy sports apps in the industry.

We’ll touch on all of those details and more, including some tips and advice for Underdog’s fantasy games, like Best Ball and Fantasy Pick’em, in this Underdog Fantasy promo code review.

This Underdog promo code is the one that will get you the most out of Underdog as a new user—by far. It lets you maximize your deposit via the match and is super easy to claim.

• Underdog Fantasy is a fantasy sports platform that specializes in Best Ball formats, as well as fantasy pick’em games.

• Underdog offers other exclusive bonuses and promotions for NFL, NBA, PGA, and MLB prize pool contests.

Underdog Deposit Match Terms and Conditions

Currently, there is no expiration date to claim the Underdog promo code. But the offer can change or go away at any time, so I’d recommend cashing in now.

Once you claim the Underdog bonus, you must meet the playthrough requirements within 14 days to receive any winnings on it, so make sure you’re prepared to cash in.

For instance, let’s say you’re ambitious and deposit $2K to get the whole $1K signup bonus (it’s a 50% match, not 100%).

You might feel pressured to place $1K in picks over 14 days, so a smaller deposit and match might be more appropriate. Of course, this route is also friendlier to your budget overall.

But the fun doesn’t stop at the Underdog signup bonus. Here are some ongoing promos for existing Underdog users:

My Experience With Underdog Fantasy

I’ve lived in three different states over the last two years (well, two states plus the nation’s capital). Going from Washington, D.C., to Texas, and now Florida, I’ve played on Underdog Fantasy’s app continuously across the country during that time. Two of those locations even have legal online sports betting, but I love Underdog Fantasy contests so much that the Underdog Fantasy mobile app is still my go-to over others.

If you’re in the Lone Star State like I was at one point, check out our guide to Underdog Fantasy Texas.

As someone who was first frustrated with the initially limited online sports betting options in DC, I turned to Underdog and its signup bonus as a way to get some skin in the game. I quickly found out that their best ball contests were actually more fun than sports betting or any other fantasy sports format I’ve played, and it took no time to adjust to the Underdog Fantasy mobile app.

Since I’m so often playing Underdog contests, friends and family often ask me questions like “is Underdog Fantasy legit?” or “is Underdog Fantasy legal?” The answer is yes and yes.

DFS and traditional fantasy sports fans will love Underdog’s best ball tournaments. If you’re a sports bettor who enjoys player prop bets, then Underdog’s pick’em games might be better suited for you.

What I’ve Discovered About Underdog Fantasy

Here’s what I’ve discovered about Underdog Fantasy:

• Exceptional app: Underdog Fantasy offers a pretty streamlined experience across any devices. I’ve made my fair share of picks on desktop, but you really can’t beat the Underdog app that’s compatible on iOS and Android. On my iPhone, I’ve found it easy to deposit, withdrawal, enter contests, and keep an eye on my picks. I’m particularly fond of the dark mode toggle, as the contrast makes it much easier to sort through picks.
• Best ball fun: If you’re gonna download Underdog for one thing, it should be its Best Ball fantasy contests. It takes the drag out of fantasy sports and somehow has even managed to make golf exciting for me.
• Accessibility: Underdog Fantasy is widely available. As I mentioned, I was able to play it despite my various relocations over the past couple of years.
• Simplicity: Even a pretty seasoned fantasy player like myself can appreciate the simpler side of the game. At Underdog Fantasy, sometimes I like (and even prefer) the straightforward nature of its pick’em contests. Even beginners can get in on the fun with this super easy format.
• Welcome offer: The Underdog Fantasy promo code lets you get a signup bonus that’s pretty high compared to others in the industry. Sure, it requires some investment on your part, but it can help you significantly boost your bankroll.

Where Underdog Can Improve

As great as the Underdog Fantasy app is, there’s definitely room for improvement. And I want it to improve, so if I could talk to the Underdog CEO, here’s what I’d relay:

• The lack of a rewards program is frustrating—so many other DFS sites have one, so why not Underdog? Getting points, bonuses, SOMETHING for my business would make me a lot more inclined to come back (even though I admittedly already do).
• I hate to ask for free stuff, but I think Underdog is missing out by not giving new users a free entry. It would be the perfect opportunity for people to test out, say, best ball, and fall in love with how easy it is to play.

Is Underdog Fantasy Legit?

Yes—while it might not have as much traction as other big DFS sites, the Underdog Fantasy promo code and platform are as legit as it gets. It has backing from the likes of Kevin Durant, Mark Cuban, and BlackRock in addition to complying with local DFS regulations. You can trust the app’s security and that it will give you your winnings fair and square.

Right now you can enter and play daily, weekly, season-long, and pick’em contests for multiple sports. NFL/CFB/NBA/CBB best ball contests are also taking shape on Underdog Fantasy’s app. The Underdog Fantasy lobby is loaded with options, including pick’em games for NBA, CBB, NHL, Soccer, MMA, Esports, MLB, PGA, and NFL prop picks.

You can also participate in live fantasy snake drafts for this week’s basketball and hockey slates. And if it’s best ball you’re looking for, you can start drafting teams for MLB and NFL best ball leagues, plus drafts are available for the NBA season.

Perhaps most importantly, over the span of contests we’ve played at Underdog, we’ve never had an issue with deposits and withdrawals.

Why We Love Underdog Fantasy Here at RotoGrinders

It’s hard to be succinct when explaining why we love Underdog. But we’ll give it a try—it’s simple, hosts contests like Best Ball Mania III with massive prizes, has a user-friendly mobile app, and has various ongoing promos.

Perhaps one of Underdog’s biggest draws is its access to college football. This offering is particularly big for SEC football fans, considering that many southeastern states don’t have operators with legal online sports betting licenses. And even if they do, restrictions on college props can restrict your play.

But with Underdog’s various contests, you can get in on the college ball action despite many legal regulations that prohibit other types of real money play and the claiming of bonuses like the Underdog Fantasy promo code.

Underdog Fantasy Contests & Games

Underdog Fantasy began by offering four games for the four major sports NFL, NBA, MLB and NHL. The site didn’t stop there, though. They have since added college sports, including college basketball during March Madness to their game menus.

Other offerings include CFB, FIFA, Soccer, Esports, Tennis, PGA, WCBB, Basketball, and Golf, all of which are eligible via the Underdog promo code.

As far as their contest types go, snake drafts are for season-long, daily, and weekly contests. If you want action on today’s games, you can join 2-6 man contests and start drafting now. Or you can ditch the draft and go straight to Underdog’s Pick’em offerings, called Higher/Lower & Rivals, allowing you to win as much as 20x your entry.

I go into more detail on each contest type below:

Regular Daily Fantasy Drafts

Underdog has a typical fantasy draft option, with a scoring system isn’t much different than what you see elsewhere. For their fantasy football leagues, Underdog Fantasy has adopted 0.5 PPR (points per reception) scoring.

Users can select between two different draft speeds, Fast or Slow, depending on their needs and their desired draft experience. Each user is given 30 seconds per pick in Fast Drafts, while Slow Drafts give users 8 hours per pick.

Battle Royale Daily Fantasy Draft

Battle Royale is another popular feature that is unique to Underdog.

In Battle Royale, entrants select players through a snake draft, but with a twist. Not only are you competing against others in your group, but Battle Royale is also grouped in.

You will compete one week at a time against every snake draft the group entered in your respective contest; it is possible you have the same players as other teams.

At the end of the week, the players with the highest scores are awarded prizes based on the respective pool they entered.

Tips for Drafting Your First Battle Royale Lineup

Battle Royale can be a little intimidating, so here are some tips for newbies:

• Familiarize yourself with the scoring—knowing how many points you get for, say, steals can help you make better picks.
• Do your research beforehand so that your draft time doesn’t pass you by.
• Start small—being conservative with your initial entry fee will empower you to try again if things don’t initially go your way.

Best Ball Tournament Contests

Of course, NFL Best Ball is Underdog Fantasy’s main attraction. Check out Best Ball Mania VI’s payout structures below.

How to Play Best Ball

I’ve been playing best ball for a few years now, and by far my favorite thing is how many drafts it allows me to compete in during the dog days of summer. Once NBA ends, I anxiously await football season but best ball provides an outlet for me even if my friends aren’t ready to start drafting their fantasy teams.

But of course, Best Ball really ramps up before Week 1, just like traditional NFL fantasy football.

There are several different types of best ball games offered by Underdog, with the differences mostly having to do with group size, entry fee, prize payouts, and number of entries per user. But they all have several common characteristics, including:

• Snake Draft – This is common in many season-long fantasy leagues. The last person to draft in the first round gets the first pick in the second round, which means the first person to draft gets the last pick in the second round and the first pick in the third round, and so on.
• Set Rosters – Once you draft a team, that’s your team for the entire season. No waiver wires for best ball. That’s also why there are so-called slow drafts, where people have several hours to make a decision.
• No Lineups to Set – Not only is your roster set all year, you don’t even need to set a lineup each week. Underdog does the work for you, starting your highest-scoring players each week.
• Locked In Positions and Scoring – In season-long fantasy football, you can set your league scoring to however you like. Want high scoring? Go with PPR and give extra points to RBs. Want two defenses and 4 WRs and 3 QBs per team? Go nuts.

There are many, many different NFL fantasy games on Underdog, but Best Ball offers the biggest prizes, and you don’t have to draft a new team each week. If your budget and time allows, you should give Best Ball a try.

Underdog Pick’em Contests

Like other DFS apps, Underdog has pick’em contests that mimic the traditional player prop bets of sports gambling.

Users were rampant about wanting more than five picks per entry, and Underdog listened. The Underdog Fantasy app rolled out Pick8 in early June 2024 as a new way to play. You can add anywhere from 2 to 8 picks and win up to 325x your money.

When you play Pick8, note that your entries will automatically be Double Flexed. This means that you can miss up to two picks and still get paid. And, if you make 6+ picks, you can use specials in Underdog flexed entries.

Here’s some more info on the pick’em format at Underdog:

Higher/Lower

The simplest pick’em game; all you have to do is pick whether players will achieve higher or lower on a given projection (ex. Lebron James to score higher or lower than 20.5 points in a game). I’ve noticed that many users apply the Underdog promo code to this contest type since it’s one of the most straightforward.

Rivals

Pick two players to compete against each other with a spread applied (ex. Hurts vs. Sanders with Hurts +37.5 rushing yards; if you pick Sanders, he has to cover the spread for you to win).

Some Rivals matchups won’t feature a spread, and in this case, the entry would be graded as a tie.

Champions

Champions is Underdog’s version of peer-to-peer pick’em. The game is as simple as it gets—create a roster of 2-8 players, and for each player, determine whether they’ll go Higher or Lower on a projected stat.

It’s easier than it sounds, of course. If you go Standard, you have to get all of your picks right. But if you opt for Flex, you can still be a winner even if you miss one pick (Flex requires 3+ picks whereas Standard only requires 2+).

When you get your picks right, you earn Champions Points. The user in the tournament with the most Champions Points, is, well, the Champion. Other rules that are relevant to the standard pick’em games apply, including that at least two of your roster selections have to be from different teams.

Multipliers

How much can you win on Underdog? Here is a breakdown of what you stand to potentially win in Underdog Pick’em contests (standard entries only):

• 2-pick entry: 3x
• 3-pick entry: 6x
• 4-pick entry: 10x
• 5-pick entry: 20x
• 6-pick entry: 35x
• 7-pick entry: 65x
• 8-pick entry: 120x

Underdog Pick’em in Colorado

Underdog pick’em contests are as strong as ever in Colorado. The state helped set precedent by allowing this DFS app and others like it to coexist with existing legal sportsbooks.

Legislation helped distinguish Underdog’s fantasy sports from traditional online sports betting by establishing that users must make entries with at least four athletes (rather than two in other states). Plus, users have to rely on fantasy points instead of actual betting lines.

Regardless, the result is that you can use Underdog Fantasy in Colorado to get in on the action. Local favorites include the Rockies, Broncos, and Avalanche, though Colorado users will be able to play on various teams via the Underdog app.

Playing College Football on Underdog Fantasy

As a huge college football fan, I’m pumped to see that Underdog is expanding their best ball contests into the college football space.

I’m telling my friends and family who love college football to take advantage of the Underdog promo code and use it for entries into Best Bowl Mania. Especially for those in states that have yet to legalize online sports betting or college football player props, Underdog is the perfect alternative.

Some things to keep in mind about NCAA football on Underdog include:

• No NCAA daily fantasy drafts
• Pick’em and rivals are available for NCAA
• No live scoring for college football
• You often have to wait until Thursday mornings ahead of Saturday games to find the NCAA pick’em options

NCAA football picks are particularly popular at Underdog Georgia thanks to the likes of the Georgia Bulldogs.

Underdog Fantasy Withdrawal and Payouts

While its deposit and withdrawal options were once pretty limited, Underdog Fantasy has since expanded its payout methods.

When I’m ready to get my money out, I usually lean on PayPal. But Underdog also offers payouts via Interchecks—once you set up an account through this service and connect it to your Underdog account, you can choose to get your funds via physical checks, electronic checks, or straight to your bank account via direct deposits.

Withdrawal processing times vary by volume and method, but I usually get my winnings within 24 hours (especially when I use PayPal). Note that withdrawal methods usually have to be connected to an initial deposit source.

Note that the Underdog bonus cash you get from the deposit match is subject to rollover requirements. Underdog Fantasy does it this way so that users can’t just take their bonus money and run. The good news is that the rollover requirement is only 1x, meaning you only have to play through your bonus cash once before you can withdraw any winnings on it.

Withdrawals are always free no matter the multiplier, but you must withdraw at least $10 at a time.

Does Underdog Have Early Cashouts?

Sort of. The “Win Now” feature originated on Underdog Champions contests, letting you lock in your Champions points and win a specified amount after the contest ends.

I appreciate that the “Win Now” feature was extended to Streaks, so if you want to take the money and run on your Streak, you can. If you hit your first few picks, you don’t necessarily have to wait to see if the rest of your picks are also winners to walk away on top.

Deposits on Underdog

I’ve found it super convenient to fund my account balance thanks to all of these methods:

• Instant bank transfers via Trustly
• Credit or debit card (Visa, Mastercard, American Express, Discover)
• PayPal

You’ll need to use at least one of these deposit methods to not only fund your account but also qualify for the deposit match. Remember that the minimum deposit at Underdog is $10 and deposits are processed instantly.

Once your deposit has been made, you’re ready to find a contest. And remember that all your personal information is safe with Underdog.

All legal DFS companies, including Underdog, have to comply with strict state regulations that safeguard the storage of personal information. Your information is as safe with Underdog as it is with PayPal, Amazon, or any other large company.

Where Is Underdog Fantasy Legal?

The Underdog promo code and app are legal in 41 states (including DC), though the types of contests you can participate in will vary. Check out our table for a full breakdown of Underdog Fantasy legal states and their corresponding contests:

Now that I live and play in the Sunshine State, it’s a little frustrating that I can only do Champions and Drafts on Underdog Fantasy FL and Underdog Fantasy AL and not Pick’ems against the house, but that’s a state regulations issue versus it being Underdog’s fault.

While Underdog is available in the majority of states, the Kalshi bonus is available in all of them.

Does Underdog Have a Sportsbook?

Yes. While Underdog Fantasy is the operator’s best-known product, it also owns a separate sportsbook product, Underdog Sports.

This sports gambling platform is much more restricted at the moment due to stricter regulations around legal sports betting but is currently legal in North Carolina and rolled out in March 2024.

In April 2025, Underdog rolled its North Carolina sportsbook into the fantasy app so that both products were in one place. Users can access all sportsbook bets (in North Carolina) and fantasy picks through the same Underdog account.

How to Create an Underdog Fantasy Account

Creating an Underdog Fantasy account is simple:

1. Sign up via the links on this page and enter the Underdog promo code to get the welcome offer.

2. Provide personal info like your email address, date of birth, etc.

How Underdog Fantasy’s Customer Service Stacks Up

If you end up needing help on Underdog, you’ll be glad to hear that the customer service team is pretty helpful.

The most common support method is the live chat feature, though you may also DM the Twitter/X account at @UDSupport or email support@underdogfantasy.com.

Support is available 24/7, though response times can vary depending on volume. And from what we’ve seen, Underdog often hits users with the “volume is higher than usual” disclaimer.

Note that the live chat feature takes you through several automated prompts before you can talk to a live person. You must also verify your account before getting to talk to an actual customer service rep instead of a robot.

Overall, we’ve had positive experiences with the Underdog customer service team that operates with integrity and is committed to helping you with your account, whether you have payment issues or even need to facilitate a closure.

Underdog Fantasy Mobile App Reviews

Here are some more balanced reviews to complement everything I’ve already touched on:

“I like the app overall. Gives a discount almost every day… The only problem is the costumer service. My girlfriend’s account got restricted because we use my phone for both of our accounts. We were not aware that this was prohibited… She had to email them that she understand what she did wrong and that she won’t do it anymore which she did… She emailed them about 3 times and still no response. Every other app we use, we get a reply within a day.”

– Katkins0420, iOS User who left a 4-star rating on the App Store

“It’s cool, my go to, just wish it was more props for soccer and tennis and basketball, like i think the app will be better if we had more variety in choices, and picture icons, and a way to message users. Also wish withdrawals were a bit better but cool promotions sometimes, thanks UD”

– Chase, Android User who left a 4-star rating on the Google Play Store

Other Reviews From Underdog Users

I’ve talked extensively about my experience with the Underdog promo code and app, but what are other user reviews saying?

“You may or may not have heard of Underdog Fantasy, but seeing as you are reading this, you must know by now. Seriously, Underdog has become a major player in the DFS space, with strong brand awareness and a cool logo. (I like dogs.)

Getting to things that you actually care about, the Underdog Fantasy app may not jump out immediately, but it functions very well. The home screen welcomes you with promotions, trending picks, popular picks, and the key matchup of the day. In other words, it’s what a home screen should be.

Of course, you can also search for particular players, teams, or stat types to make picks on. And if Pick’em isn’t your thing, you can head over to Drafts and get in on some old-school DFS action.”

– Joe Beguiristain, novice DFS player

Underdog is all popular among experienced daily fantasy sports players, so here are thoughts from a user who’s been around the block:

“Making picks for NBA or NFL games on DFS apps has been something fun for me to research and do for years now. Sleeper and PrizePicks are the most popular ones for me and my friends, but we’d heard a lot about Underdog Fantasy too. Underdog’s reputation is pretty good, so I decided to add it to my DFS rotation this year.

I was really impressed with the Underdog Fantasy app and DFS experience. Underdog has tons of great stats for all kinds of athletes to make picks on. I tend to focus on big NFL performers in important matchups, but Underdog makes it easy too to also focus on those good performers in all kinds of sports each day.

Underdog also gave me an onslaught of options for daily drafts to enjoy as well. Me and my friends will do daily drafts in basketball or football games, and we’ve added Underdog to our favorite apps because of how much fun we’ve been having. We can create our own drafts with each other or join big pools too. Underdog Fantasy has been a great DFS option for all of us who play on these each day!”

– Stephen Pierce, experienced DFS player
