How Does the Underdog Welcome Bonus Work?

Underdog keeps things pretty simple with its welcome bonus.
When you sign up using the Underdog promo code
It’s a “Play-and-Get” setup. Once you deposit at least $10 and enter a contest for $5, Underdog will credit your account with $50 in bonus entries—no matter if that first entry wins or loses.
That’s a big difference from some other DFS apps, where you only get a bonus if your first play loses. Here, you get the bonus either way, so you can jump right into more contests without having to chase anything.
| 💰 Minimum Deposit | $10+ |
| 🎁 Qualifying play | $5 entry |
| 🎁 Bonus Reward | $50 in bonus entries |
| ⏱️ Bonus Expiration | Bonus expires after 14 days |
| 👑Bonus Type | Play & Get (Win or Lose) |
| 📝 Wagering requirement | 1x playthrough on bonus entries. |

Browsing the current Pick’em board reveals an awesome variety of contests to explore right now.
Deep playoff basketball offers fantastic predictability, as head coaches completely lean on their core starters and push their court time to the absolute max. Over on the ice, the intense postseason action means guys who constantly funnel pucks to the net become incredibly valuable assets. Plus, baseball grinders have endless daily opportunities to hunt for edges against vulnerable bullpens or strikeout-prone lineups.
The biggest secret to crafting a winning ticket is logical pairing. For example, if you expect a slow, defensive-minded hoops matchup, it makes perfect sense to combine a ‘Lower’ on the main playmaker’s passing totals with a ‘Lower’ on his big man’s scoring output. Connecting these related outcomes directly boosts your win probability and squeezes every ounce of value out of those extra promotional funds.

How to Use the Underdog Promo Code
Not only will promo code
- Use the links on this page to go to the Underdog site or app.
- Enter the Underdog promo code
GRINDERS , if it didn’t auto-fill. - Complete your registration and verify your account.
- Deposit at least $10.
- Enter a contest with $5 to trigger the bonus.
Once your first entry settles, you’ll receive $50 in bonus entries.
From there, you can start building Pick’em entries, joining drafts, or testing different contest types depending on what’s available in your state.
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.
Underdog Promo vs Other DFS Promos
Underdog isn’t the only DFS app offering a welcome bonus, but its Play $5, Get $50 structure stands out for how easy it is to use.
Here’s how it compares to other popular DFS promos:
| 📱 DFS App | 💰 Bonus Offer | ⭐ Promo Code |
| Underdog | ||
| DraftKings Pick6 | | |
| Sleeper | ||
| Dabble | | |
| Bleacher Nation Fantasy | | |
| Betr Picks | ||
| Boom Sports | ||
| Chalkboard | ||
| PrizePicks |
The biggest difference is how quickly you can use your bonus. With Underdog, you get guaranteed entries after your first play, instead of having to unlock a deposit match over time.
If you’re planning to deposit a larger amount upfront, a deposit match might offer more total value. But if you want something simple and immediate, Underdog’s play-and-get format is one of the easiest ways to get started.
Why Use Underdog Promo Code GRINDERS?
While a lot of DFS apps lean on deposit matches with playthrough requirements, the
Here is why we think this play-and-get structure is the best route for new players:
- Guaranteed Bonus Value: You’ll receive $50 in bonus entries after your first $5 play—win or lose. Some platforms only reward losing entries, but Underdog credits your account either way.
- Low Barrier to Entry: You only need a $10 minimum deposit to qualify, making it easy to get started without committing a large bankroll.
- Works for All Modes: Bonus entries aren’t locked into one format. You can use them on Pick’em contests, Best Ball drafts, or other available games depending on your state.
- No complicated rollover: Unlike traditional deposit bonuses, there’s no long grind to unlock value. You can start entering contests and building lineups right away.
- Verified for 2026: Our
GRINDERS code is tested daily by the DFS experts at RotoGrinders to ensure it remains active and valid across all eligible states.
It’s that easy to claim the code and start exploring Underdog’s massive lobby of pick’em options and daily fantasy drafts.
How Much Is the Underdog Promo Code Worth?
Before you jump into your first entry, it’s worth understanding what this offer actually gives you in DFS terms—not just the headline number.
- You deposit $10
- You play $5
- You receive $50 in bonus entries
That gives you $55 total in playable entries right away.
In other words, you’re turning a small entry into multiple chances to build lineups and test different strategies without committing a big bankroll. What matters here is how you use those bonus entries.
Because Underdog instantly credits your bonus entries, you gain the immediate freedom to experiment with different pick’em strategies. You do not have to burn through your actual cash bankroll. With the Conference Finals in full swing, here is a sharp approach for deploying your funds right now:
- Target Stale Projections: Late-May playoff lines shift incredibly fast. One beat reporter tweeting about a player’s nagging injury can alter the entire board. Monitor the news closely. Lock in your ‘Higher/Lower’ picks before the algorithm adjusts.
- Master Correlation: Always consider how game scripts intertwine. Expecting an NBA shootout? Pair a ‘Higher’ points projection for the primary scorer with a ‘Higher’ assists prop for the team’s point guard.
- Use the Flex: Playoff basketball is volatile. A sudden blowout means starters sit the entire fourth quarter. Do not force a flawless standard entry. Use the Flex feature as crucial insurance. It protects you from bad beats and unpredictable game scripts.
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 use right away.
What Can You Win?
From there, your potential returns depend on how you build your entries. Here are the maximum multipliers for standard Pick’em contests (all picks 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
Underdog also offers Flex entries, which act as built-in insurance. If you miss one pick, you can still win—though for a lower payout. For example, a 5-pick Standard entry pays 20x, while a 5-pick Flex pays 10x if all five hit, or 2.5x if you go 4-for-5.
Bonus entries come with a simple 1x playthrough requirement, meaning you only need to play them once before withdrawing any winnings generated from them.
Withdrawals are free and start at a $10 minimum. You can cash out using PayPal, Trustly, or Paysafe, and most withdrawals are processed within 48 to 72 hours.

Is Underdog Legit and Safe?
Yes. Underdog is a highly secure, legitimate DFS platform backed by major investors. The platform uses industry-standard security to protect your data and processes transactions reliably.

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’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.
While Underdog is available in the majority of states, so is the Kalshi bonus.
Our Favorite Underdog Picks Today, May 22, 2026
Here are a few of our favorite Underdog Pick’em plays for today’s slate:
| League | Player | Higher/Lower Projection |
| NBA | Shai Gilgeous-Alexander | Lower than 11.5 Rebounds & Assists |
| NBA | Jared McCain | Lower than 5.5 Points |
| NBA | Ajay Mitchell | Higher than 10.5 Points |
Updated 05/22/2026 8:15 AM ET – Fantasy Pick’em – Subject to Change. These fantasy picks are eligible to be used with the Underdog promo code.
Putting together a winning ticket from the ground up? I always suggest locking in your foundation with guaranteed volume. Now that we’ve reached the NBA and NHL Conference Finals, you have to anticipate massive game-to-game tactical shifts. If a primary scorer had a surprisingly quiet opening game, expect their usage rate to absolutely spike in Game 2 as the coaching staff makes aggressive adjustments to get them the ball.
A fantastic strategy right now is to build a cross-sport slip by pairing one of those bounce-back basketball projections with a high-floor MLB strikeout prop. Just make sure you are checking in with team beat writers on Twitter about an hour before lock. A sudden starting lineup tweak or a sneaky injury report can completely flip the expected value on your entry!
If you want to go deeper, you can access all of our best Underdog picks today, with premium predictions from our expert projections team.
Mastering the Conference Finals Slate on Underdog Pick’em
Now that we are deep into the third round of the postseason, the projection lines are incredibly sharp. Just tapping the “Higher” button next to your favorite athletes won’t cut it anymore. If you want to maintain a profitable edge during this high-stakes stretch, you need to evolve your approach. Here are the specific tactics I am using to beat the board this weekend:
- Capitalizing on Venue Shifts: When a basketball series changes cities for Games 3 and 4, the supporting cast usually gets a massive surge of confidence. While top-tier superstars carry the offense on the road, role players historically shoot much better in front of their home crowd. Grabbing the ‘Higher’ on a secondary shooter’s three-point props as they return to their own arena is a fantastic, data-backed angle.
- Exploiting Deep-Series Hockey Fatigue: As these grueling hockey series progress, the physical toll adds up fast. Legs get heavy, odd-man rushes disappear, and blocking shots becomes the primary focus. This creates the perfect recipe to fade total goals. Instead of chasing offensive stats, I love locking in the ‘Higher’ on goalie save counts or blocked shots for those gritty defensive defensemen.
- Spotting Weekend Baseball Rest Days: Saturday and Sunday baseball schedules constantly feature day games right after night games. Managers routinely bench their starting catchers or sit a veteran bat to keep them fresh. Always check the official lineup cards before you lock in a ticket. If an offense is rolling out their backup squad, immediately target the ‘Higher’ on the opposing starting pitcher’s strikeout and outs-recorded props!
Late-May Pick’em Strategy: Surviving Postseason Variance
Late May delivers a highly concentrated NBA and NHL playoff schedule. The volume of games drops, pushing the betting public to hammer the exact same superstar projections. This herd mentality frequently warps the board.
You need discipline to survive this variance. Follow these guidelines heading into Memorial Day weekend:
- Ignore the Public Noise: A bad shooting night from an elite scorer causes public panic. People rush to smash the ‘Lower’ on their next game. Bet against this overreaction. Great players bounce back.
- Exploit Friday Baseball: Stop forcing terrible basketball picks just to have action on national television. A standard Friday MLB slate is loaded with value. Attack pitching strikeout numbers. The casual crowd completely ignores these games.
- Pivot to Rivals: Sometimes predicting a raw point total is too difficult. Switch your approach. The Rivals format lets you pick one player to outscore another. You skip the headache of predicting game pace entirely.
Smarter Strategies for MLB Strikeout Props
Let’s talk baseball! While a lot of casual fans might be distracted by all the intense playoff hoops action right now, smart DFS players know that the daily baseball grind is an absolute goldmine—especially when it comes to pitcher strikeout props.
Sometimes, the projections for top-tier arms (like Shota Imanaga, Seth Lugo, or Bryan Woo) get set just a bit too high when they are facing disciplined lineups that rarely swing and miss. Strikeout props can definitely be a bit of a rollercoaster, but they are highly profitable if you follow a few key guidelines when building your slips:
- Look at Recent Splits, Not Just Season Stats: Instead of just trusting a pitcher’s season-long numbers, dig into how the opposing team has actually performed against lefties or righties over the past two weeks. Recent form tells a much better story than a season-long average!
- Check Workloads and Bullpen Rest: Always take a peek at a pitcher’s recent pitch counts and their team’s bullpen availability. If a starter is coming off a high-stress game, or if their top relievers are completely rested from an off-day, managers are way more likely to pull the starter at the first sign of trouble. That makes grabbing the “Lower” incredibly appealing.
- Don’t Ignore the Umpires and Weather: Never underestimate external factors! Weather dictates pitch movement, and umpires absolutely dictate the strike zone. A humid, hitter-friendly park combined with an ump who has a famously tight strike zone drives up pitch counts fast, knocking starters out early and easily cashing those “Lower” tickets.
- Correlate with Opposing Batters: If you’re confident in taking the “Lower” on a starting pitcher’s strikeouts, try to logically correlate that pick by grabbing “Higher” on total bases for the opposing team’s leadoff hitter. Think about it: if the starter struggles and gets pulled early, the top of the batting order is inevitably going to get more trips to the plate!
Grinding these specific baseball edges is the perfect way to steadily build up your bankroll for those massive weekend contests!
Navigating High-Stakes NBA Games on Underdog
There is nothing quite like the tension of an NBA Conference Finals, but that emotion can be a massive trap for daily fantasy players. Because casual fans flock to these primetime matchups, the ‘Higher’ projections on superstar point totals often become artificially inflated by public bias. To find true value, you have to look past the scoring column.
I constantly target the peripheral stats—like rebounds, assists, or combined defensive metrics. For instance, if an opposing defense is aggressively double-teaming a player like Donovan Mitchell, his raw point total might suffer, but his assist numbers could skyrocket as he kicks out to open shooters.
Always build your Underdog entries based on expected defensive schemes rather than blind hope that your favorite player drops forty points. Betting with logic over emotion is the fundamental rule of surviving the playoff grind.
My Experience With Underdog
I’ve used Underdog across multiple states and slates, and overall, it’s one of the more reliable DFS apps available right now.
The app is fast and easy to navigate, especially when building Pick’em entries or joining drafts. Deposits and withdrawals are straightforward, and I haven’t run into major issues with payments or contest grading.
Where Underdog really stands out is in its simplicity. Pick’em contests are easy to understand, and Underdog Best Ball drafts remove the need for constant lineup management, which makes it a good fit for both new and experienced players.
That said, there are a few areas where it could improve. There’s no formal rewards or loyalty program, which some competing DFS apps offer. Customer support is also limited to chat and email, so if you prefer phone support, that’s something to keep in mind.
Overall, Underdog is pretty straightforward and has a good mix of contests, especially for Pick’em and Best Ball players.
Pros & Cons
After playing on the app across multiple states and testing out the latest features for the spring sports calendar, here’s my honest take on where Underdog shines and where they still have some work to do.
| ✅ Pros | ❌ Cons |
|---|---|
| Easy-to-use app with a clean interface | No rewards or loyalty program |
| Bonus is simple and easy to unlock | Withdrawals can take 48–72 hours |
| Pick’em format is quick and beginner-friendly | No phone support (chat/email only) |
| High multipliers (up to 120x+ on Pick’em entries) | Lower payouts when using Flex entries |
| Best Ball contests require no lineup management | Some formats vary by state |
| Strong variety of contests across major sports | Limited availability in certain states |
Underdog Contests & Games

Underdog started with the major sports—NFL, NBA, MLB, and NHL—but has since expanded to include college sports and other offerings like soccer, tennis, PGA, and esports.
When it comes to NFL DFS, Underdog stands out with simple but competitive formats that work for both casual and experienced players.
You can jump into snake drafts for daily, weekly, or season-long contests, or go straight to Pick’em with Higher/Lower and Rivals, where payouts can reach up to 20x your entry.
| SPORTS | FANTASY PICK’EM | DAILY SNAKE DRAFTS | BEST BALL | NOTABLE TOURNAMENTS | PRIZE POOL | TOP PRIZE |

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.
If you want to try a unique draft game, check out Griddy’s fantasy football puzzle game.
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.

Best Ball is a draft-only format where you pick your team at the start of the season, and Underdog automatically sets your highest-scoring lineup each week—no management required.
All contests use a snake draft, and once your roster is set, there are no waivers or lineup decisions. That makes it a great option if you want a more hands-off fantasy experience.
Best Ball contests vary by entry fee and prize pool, but they all follow the same core structure. It’s also where some of Underdog’s biggest tournaments and payouts are available.

Our DFS podcasts offer general insights for players interested in formats like best ball and daily drafts.
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
Some things to keep in mind:
- 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
Underdog Pick’em Contests
Like other DFS apps, Underdog has pick’em contests that mimic the traditional player prop bets of sports betting.
You can build entries with 2 to 8 picks, with payouts increasing as you add more selections—larger entries offer higher multipliers, while Flex options give you some room for error if not every pick hits.
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.
I’ve noticed that many users apply the Underdog promo code
Rivals
Choose between two players with a spread applied. If your pick covers the spread, you win. Some matchups may be graded as a tie if no spread is included.
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
A peer-to-peer Pick’em format where you build a lineup of 2–8 players. Standard entries require all picks to hit, while Flex entries allow you to miss one and still cash for a reduced payout.
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 NBA playoffs.
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 is a progressive format where payouts increase as each pick hits. The further you climb, the higher the multiplier.
For more details, check out our Underdog Ladders guide!
Flex Play
Mastering the Flex Play format is a mandatory skill for surviving the brutal variance of the late-May sports schedule. Underdog allows you to apply a Flex to any Pick’em entry featuring three or more selections. Instead of requiring a perfect sweep, this built-in insurance policy keeps your slip alive if one projection fails.
Let us examine how this functions during a chaotic Friday night slate. Imagine you build a four-pick ticket. You take an NHL center for higher shots on goal, an NBA forward for higher rebounds, and two MLB pitchers for higher strikeouts. A standard entry requires all four to hit for a massive 10x payout. If a pitcher gets pulled early due to a sudden rain delay, your entire standard ticket dies immediately.
A Flex Play changes the math entirely. That same four-pick slip pays 6x if you go a perfect four-for-four. However, if that weather delay ruins your baseball projection, you still walk away with a 1.5x payout for hitting the other three. You salvage a profit from a bad beat.
This strategy is highly effective during the NBA and NHL Conference Finals. Blowouts happen frequently. Starters end up sitting out the entire fourth quarter, destroying ‘Higher’ projections. Applying the Flex protects your bankroll from unpredictable coaching decisions and strange game scripts. Smart DFS players gladly sacrifice the absolute highest multiplier ceiling in exchange for long-term sustainability.
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.

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).
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.
- 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.
Underdog Customer Service
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.
Underdog Mobile App Review (May 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’s what real users have to say:
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
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!

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
