While the headline is simple, the real edge comes from knowing how to navigate the app’s quirks before the first pitch. With MLB Opening Week in full swing and the NBA playoff push heating up, the board is moving fast. Sticking points like failed location checks or ID mismatches can sideline you right as a high-value projection drops, so getting your account verified early is a must.

We’re breaking down how to maximize the GRINDERS bonus, which states offer the best contest variety, and how to avoid common deposit hurdles.

This way, you can focus on building your pick’em entries for tonight’s 76ers vs. Heat and Pistons vs. Thunder matchups without hitting a technical wall.

Underdog Promo Code GRINDERS for March 2026

The best Underdog promo code is GRINDERS. When new users enter this code at signup, they score the welcome offer of Play $5, Get $50 in Bonus Entries!

Underdog signup code GRINDERS is exclusive to new customers at this top DFS app. Even though the bonus hits your account after you make a $5 entry, you must meet the $10 minimum deposit requirement.

Does Underdog have a welcome bonus?

Yes, Underdog currently offers one of the best values for new players. When you sign up using the Underdog promo code GRINDERS, you can claim this offer: Play $5, Get $50 in Bonus Entries!

Unlike some other DFS apps that only give you a bonus if your first entry loses, Underdog’s “Play-and-Get” structure is guaranteed. As long as you deposit at least $10 and play a $5 entry, the $50 in bonus entries will hit your account whether your picks are correct or not. It’s a great way to build your bankroll for MLB Opening Week action tonight, like the Pirates vs. Reds (6:40 p.m. ET, FS1) or the Giants vs. Padres (9:40 p.m. ET, FS1).

If you prefer building entries for the NBA playoff push, you can target tonight’s doubleheader featuring the 76ers vs. Heat (7 p.m. ET) and Pistons vs. Thunder (9:30 p.m. ET) on Peacock.

How to Use the Underdog Promo Code

Not only will promo code GRINDERS get you the best fantasy offer at Underdog—it’s super easy to claim.

Here’s how to set up an account using the Underdog promo code:

1. Use the links on this page to go to the Underdog site or app.

2. Enter the Underdog promo code GRINDERS if it didn’t autopopulate.

3. Follow prompts to complete registration and verification.

4. Make a $10 minimum deposit.

5. Play $5 to get the play-and-get bonus.

It only takes a few minutes to be up and running and ready to enter one of the many contests available on the app, available on the Apple App Store and Google Play Store.

Why Your Underdog Promo Code Might Not Work

If your Underdog promo code isn’t working, the code itself isn’t usually the problem. More often than not, it comes down to location, account details, or payment info during signup.

• First, check state availability. Underdog does not offer the same contests in every state, so if you don’t see the format you expected, it may be a state issue rather than a promo issue.
• Next, look at location settings. Underdog verifies where you are physically located. So if you have a VPN, Private Relay, or anything else masking your location, signup or deposits can fail even if you’re in an eligible state.
• It’s also worth checking your account details. Your name, address, and date of birth should match your ID exactly. Small mismatches can trigger verification problems and slow down the process.
• Then review your payment method. A failed deposit can make it seem like the promo didn’t apply, when really the billing details didn’t match or the payment source was flagged. If one method keeps failing, try a different one.

One last thing: bonus funds are not the same as cash you can withdraw. You may need to meet the promo terms before those funds become withdrawable. So before assuming the code failed, check your location, state eligibility, account info, and deposit method first. In most cases, that’s where the issue is.

How Much Is the Underdog Promo Code Actually Worth?

Before you jump into your first entry, it’s worth understanding what this offer realistically returns in DFS terms—not just the headline number.

What matters here is how you use those bonus entries.

Unlike deposit match promos (which can take dozens of entries to unlock), Underdog’s play-and-get structure gives you immediate access to your bonus. That means you can spread those entries across multiple pick’em slips instead of forcing volume.

A practical approach:

• Use 2–3 pick entries early to stabilize returns
• Mix in Flex entries to reduce risk on volatile projections
• Save a portion of bonus entries for late-day lineup updates when projections shift

Most competitors lean on higher headline bonuses ($75 instead of $50), but the real edge here is usability. You’re getting guaranteed entries you can deploy right away instead of chasing rollover requirements.

Benefits of the Underdog Promo Code GRINDERS

Why should you go out of your way to use the code GRINDERS? Beyond the obvious perk of getting extra funds, the main benefit is immediate bankroll flexibility.

Because Underdog utilizes a guaranteed “play-and-get” structure rather than a traditional deposit match with steep rollover requirements, you can instantly test out different entry strategies. For example, you can use your own cash to play it safe on a standard 2-pick entry, then turn around and use your bonus entries to chase massive multipliers by stacking 6 to 8 higher/lower player projections for tonight’s MLB Opening Week action.

It essentially acts as a low-risk trial run, allowing you to get a feel for how the app updates projections and where you can find an edge during the NBA playoff push.

Underdog Payouts & Withdrawals

Want to know how much you could win with your Underdog bonus funds? Here are the maximum multipliers for pick’em contests if you run a Standard entry (meaning every pick must hit):

• 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

Competitor Insight & Bankroll Strategy: Unlike some older DFS platforms, Underdog allows you to “Flex” your entries for 3-8 picks. Think of a Flex entry as built-in pick’em insurance. If you miss one player projection, you still secure a payout, though your overall multiplier ceiling is lowered. For example, an all-or-nothing 5-pick Standard entry pays 20x, but a 5-pick Flex pays 10x if all five hit, or 2.5x if you go 4-for-5. Utilizing Flex entries is a very smart bankroll strategy to navigate the early unpredictability of MLB Opening Week.

Note that the Underdog bonus cash you get is subject to a 1x rollover requirement. This means you only have to play through your bonus entries once before you can withdraw any net winnings from them.

Withdrawals are always free and carry a $10 minimum, though you can cash out your entire remaining balance if it happens to dip below that mark. You can pull your funds using PayPal, Trustly, or Paysafe, and while withdrawal processing times depend on platform volume, your winnings will typically hit your account within 48 to 72 hours.

Underdog Promos for Existing Users

Once you sign up with the Underdog promo code GRINDERS, you’ll get Play $5, Get $50 in Bonus Entries!

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

Underdog Promo vs Other DFS Promos

Underdog’s promo is far from the only daily fantasy offer out there. See how Underdog’s offer compares to competitors in terms of type and overall value.

For instance, the play-and-get at Underdog might be more valuable to new fantasy players. But if you’re planning on depositing a bunch at signup anyway, a deposit match might be more your speed.

The good news is that you can claim all of these offers if you wanted to and use their bonus to test each app!

My Experience With Underdog

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

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 mobile app.

Since I’m so often playing Underdog contests, friends and family usually ask me questions like “Is Underdog legit?” or “Is Underdog 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

Here’s what I’ve discovered about Underdog:

• Exceptional app: Underdog offers a pretty streamlined experience across all 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, withdraw, 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. See our Underdog Best Ball rankings for helpful insights.
• Accessibility: Underdog 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, 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 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 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.

Underdog Fantasy Pros & Cons

After playing on the app across multiple states and testing out the latest features for MLB Opening Week, here’s my honest take on where Underdog shines and where they still have some work to do.

Pros

• Massive Multipliers: You can now build entries for up to 8 picks, which triggers a huge 325x multiplier—perfect for bettors looking for a high-ceiling play during the NBA playoff push.
• Best Ball Leader: Simply put, nobody does Best Ball better. The interface for season-long drafts is incredibly smooth compared to the clunkier salary-cap models on other apps.
• Guaranteed Promo: The Play $5, Get $50 in Bonus Entries! offer is much easier to clear than the “matching” bonuses at other DFS sites that lock your funds behind steep playthrough requirements.
• App Performance: With a 4.8/5.0 rating on iOS, the app is built for speed. I’ve rarely seen it lag, even during high-traffic windows like tonight’s NBA on Peacock doubleheader.

Cons

• Withdrawal Speed: While they’ve added Venmo, some withdrawals via Trustly can still take 48–72 hours. If you’re used to “instant” sportsbook payouts, this might feel a bit slow.
• No Rewards Program: This is my biggest gripe. Unlike some competitors, Underdog doesn’t have a formal loyalty program where you rack up points for every entry you play.
• Customer Support Limits: You’re stuck with live chat and email. If you’re the type of person who wants to pick up the phone and talk to a human, you’re out of luck here.

Is Underdog Legit?

Yes—while it might not have as much traction as other big DFS sites, the Underdog promo code and platform are as legit as it gets. It has backing from the likes of Kevin Durant, Mark Cuban, and BlackRock, and it also complies 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. The best ball contests for the NFL/CFB/NBA/CBB are also taking shape on Underdog’s app. The Underdog 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 the best ball you’re looking for, you can start drafting teams for MLB and NFL’s best ball leagues. Drafts are available for the NBA season.

Our DFS podcasts offer general insights for players interested in formats like best ball and daily drafts.

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

Why We Love Underdog 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 vast 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 promo code.

Underdog Contests & Games

Underdog 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.

When it comes to NFL DFS, Underdog stands out with simple but competitive formats that appeal to both casual and experienced players.

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 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 that isn’t much different than what you see elsewhere. For their fantasy football leagues, Underdog 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; you may 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 main attraction. Check out Best Ball Mania VI’s payout structures below.

How to Play Best Ball

This format allows users to draft a team at the start of the season, with the system automatically selecting the best-performing lineup each week. It eliminates the need for weekly management, making it ideal for those who prefer a more hands-off approach to fantasy sports.

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 the 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, but 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 whatever 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 allow, 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 raving about wanting more than five picks per entry, and Underdog listened. The Underdog 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. For example, you might pick Aaron Judge to go higher or lower than 2.5 total bases during MLB Opening Night on Netflix, or Kevin Durant to score higher or lower than 26.5 points in tonight’s Rockets vs. Timberwolves matchup on ESPN.

I’ve noticed that many users apply the Underdog promo code GRINDERS to this contest type since it’s one of the most straightforward ways to build a qualifying entry.

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.

If you want to see how Underdog rivals competitors, check out our overview of the FanDuel Picks promo.

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.

If you go Standard, you have to get all of your picks exactly right to see a return. But if you opt for a Flex entry, it essentially acts as built-in pick’em insurance. You can still secure a winning payout even if one of your player projections misses (Flex requires 3+ picks, whereas Standard requires 2+).

I highly recommend utilizing Flex entries during highly unpredictable daily slates, like the chaotic MLB Opening Week or the late-season NBA playoff push.

When you get your picks right, you earn Champions Points. The user in the tournament with the most Champions Points takes the top prize. Standard Pick ’em rules apply, meaning at least two of your roster selections must be from different real-world teams.

Ladders

Underdog Ladders rolled out in Spring 2024 and is a fun way to see if your picks progressively hit. It comes with a 1x payout on the first rung, and hitting all players on higher rungs qualifies for greater multipliers.

For more details, check out our Underdog Ladders guide!

Playing College Football on Underdog

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 the 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

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 do so. 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.

Underdog Banking: Deposits & Withdrawals

Funding your account and pulling out your winnings on Underdog is simple, but there’s a catch: you generally have to withdraw using a method you’ve previously used to deposit.

As of March 2026, Venmo has joined PayPal and Trustly as a major payout option, which is a significant upgrade for speed.

Crucial Withdrawal Tip: Underdog requires an email confirmation for every withdrawal request. Once you hit “Withdraw” in the app, you have exactly 10 minutes to click the confirmation link in your inbox. If you miss that window, the request is canceled, and the funds go back to your balance. I’ve missed this more than once during busy tournament slates, so keep your email app open!

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.

Check out our review of EDGE Boost for more info on compatible Underdog banking methods.

Where Is Underdog Available?

The Underdog promo code and app are available 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 available states and their corresponding contests:

If you want to learn more about Underdog in a certain state, check out our state-specific guides!

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

What You Can Actually Play on Underdog in Your State

Underdog isn’t really a yes-or-no product anymore. What you can play depends on your state, and the differences can be pretty big. In some states, users get access to Drafts, Pick’em, College Pick’em, and College Drafts. In others, Pick’em may only be available in a specific format like Classic or Champions, and some states only allow Prediction Picks or block certain contest types entirely.

That’s why “Is Underdog legal in my state?” is only part of the question. The better question is whether your state supports the version of Underdog you actually want to play. A user in Texas may see a different product mix than a user in New York or Pennsylvania, even though all three know the Underdog name.

If you’re signing up for the promo, check state eligibility before you deposit and make sure the contest format you want is live where you are. That saves you from going to the app, seeing a different lobby than expected, and assuming the offer didn’t work. It also gives you a better reason to use the bonus right away instead of figuring things out after the fact.

Does Underdog Have a Sportsbook?

No, Underdog does not currently offer a traditional sportsbook. Instead, the company operates entirely under daily fantasy sports (DFS) regulations. Because DFS is widely classified as a game of skill rather than sports betting under federal law, Underdog’s pick’em contests and drafts are legally available in many states where standard sportsbooks are strictly prohibited (like California and Texas).

Many fans actually prefer this structure. It allows you to win real money by building higher/lower entries on your favorite players—which is perfect for tonight’s MLB Opening Night matchup between the Yankees and Giants or the ongoing NBA playoff push—without needing access to a traditional betting app.

Underdog Responsible Gaming Tools

Underdog’s focus is on making sure every player has a safe and enjoyable experience. Daily fantasy sports should be a fun way to follow your favorite sports, and it is important to play within your means.

Underdog provides several built-in resources to help you manage your time and budget effectively.

Take Control of Your Play

If you want to ensure your fantasy sports experience stays balanced, you can use the following proactive tools directly within the app:

• Self-Imposed Limits: You can set daily, weekly, or monthly restrictions on how much you deposit or the total amount you spend on entry fees. Once these limits are reached, the app will prevent further transactions until the period resets.
• Cool-Off Periods: If you feel the need to step away for a short time, the “Cool-Off” feature allows you to take a break from the platform for a few days or weeks.
• Self-Exclusion: For those who need a more permanent solution, Underdog offers a self-exclusion option. This restricts your access to the platform for a much longer duration or indefinitely.

State-Specific Protections

Depending on your location, you may notice automatic protections. For example, players in Massachusetts have a standard monthly deposit limit of $1,000, while Maryland and Tennessee also have state-mandated caps to encourage healthy play.

How Underdog’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.

• Live chat: You must verify your account before speaking to an actual customer service rep instead of a robot.
• Twitter/X: @UDSupport
• 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.

Overall, we’ve had positive experiences with the Underdog customer service team, which 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 Mobile App Review (March 2026)

Underdog currently boasts a 4.8/5.0 rating on the Apple App Store and a 4.6/5.0 on Google Play, making it one of the highest-rated DFS platforms on the market. The interface is incredibly fast when you’re trying to lock in higher/lower picks before tip-off, but no app is perfect.

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 understood 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, 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, 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 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 my friends and me, but we’d heard a lot about Underdog, 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 app and DFS experience. Underdog has tons of great stats for all kinds of athletes to make picks on. I tend to focus on prominent NFL performers in important matchups, but Underdog also makes it easy to 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. My friends and I 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 drafts with each other or join big pools, too. Underdog has been a great DFS option for all of us who play on these each day!”
