With a crucial Game 2 scheduled for Friday night alongside the epic Stanley Cup Final between the Golden Knights and Hurricanes, the sports calendar is at an absolute peak right now.

🏀​🔥Use Underdog promo code ACTION on NBA Finals: Knicks vs. Spurs (Game 2)

What a wild comeback on Wednesday night! The Knicks dug deep to erase a 14-point second-half deficit, stunning the Spurs 105-95 to grab a 1-0 series advantage. New York completely locked things down defensively in the fourth quarter, forcing critical giveaways and closing the game on a massive 11-0 run.

If you're ready to put your Underdog code ACTION bonus to work, Game 2 this Friday is going to be incredibly fun. Even better, you can grab a sweet 30% Profit Boost ($50 max) waiting for you right now in the app! Because Underdog is all about picking Higher or Lower on your favorite players' stats instead of messing with traditional point spreads, guessing how coaches will tweak their game plans after the opener is the secret to building a winning slip.


Here are a few awesome ways to approach the board for Friday’s huge rematch:

📈 Our Favorite Game 2 Projections

  • Victor Wembanyama — Higher than 26.5 Points: Even though Wemby grabbed 26 points and 12 boards in the first matchup, he struggled shooting the ball, going just 6-for-21. We know the minutes and shot volume will absolutely be there, so we love the chances of a big efficiency bounce-back. Grabbing the Higher here feels like a really solid move!

  • Jalen Brunson — Higher than 6.5 Assists (Look to pivot from 25.5 Points): Jalen went off for 30 points on Wednesday, thanks to an epic fourth-quarter takeover. Since he dominated so much, we can expect San Antonio's defense to swarm him early and try to get the ball out of his hands. Instead of chasing a high scoring total, let's look at his playmaking and passing!

  • OG Anunoby — Higher than 15.5 Points (Multiplier Boost): If the Spurs throw everything at stopping Brunson, OG is going to be the main guy left open for catch-and-shoot threes. He is in a perfect spot to exceed expectations, and Underdog is giving his line an extra 1.03x multiplier payout boost on the high side. That is fantastic value!

  • Karl-Anthony Towns — Higher than 257.5 Points + Rebounds Combo (Look for the 16.5 Points baseline): New York totally controlled the glass in Game 1, turning offensive boards into huge second-chance points. KAT is going to keep eating up those interior put-backs, making his combo stats super safe to rely on.

🧠 Quick Strategic Reminders for Friday Night

  • Don't Overreact to the Opener: Oddsmakers actually still see San Antonio as a strong favorite to bounce back on Friday. We should expect a much cleaner, more focused Spurs squad that protects the ball better after those five costly turnovers in Wednesday's final quarter.

  • Keep an Eye on the Game Pace: The first game turned into a really gritty, physical half-court battle. When the game slows down like that, it's super smart to look at peripheral stats like rebounds and assists, since those numbers stay consistent even if the shots aren't falling.

What do you guys think? Are you riding with Wemby’s bounce-back game, or backing the Knicks’ role players to keep shining on your Friday night slip?

Is the Underdog Promo Code Legit?

Absolutely. The Underdog promo code ACTION is fully legitimate. I never push a DFS platform or bonus code without personally testing the mechanics first.

I created a fresh account, entered the code, and deposited my cash. The $50 in Bonus Entries appeared instantly after my first $5 play. No shady terms. No runaround from customer service. It simply works.

Daily Underdog Promotions for June 07, 2026

Reviewing the promotions tab before constructing your daily entries is the best way to sustain long-term profitability. Ignoring this step simply leaves potential value on the table.

Underdog routinely releases heavily discounted player specials for marquee athletes right before tip-off or the first pitch. Picture grabbing a superstar marked down to 0.5 total points instead of their standard lofty projection. These aggressive markdowns hand you a significant mathematical advantage. Whenever these specials surface on the board, anchor your slip around them to boost your overall win probability.

Beyond those flash discounts, the platform hosts several recurring campaigns. From streak challenges that amplify payouts to featured daily drafts spanning multiple sports, the lobby remains packed with lucrative chances. Developing a habit of checking the promotional banners every morning establishes a strong foundation for bankroll management.

    • Streaks: Select at least two athletes from different teams and try to build a winning streak. Tally 11 consecutive wins and you can earn up to 5000x your entry.

    • Featured Drafts: Check the app daily for specialized, featured drafts across major associations like the  WNBA, MLB, PGA, and NFL.

    • Favorite Players: Keep tabs on your top performers. Tap the heart (❤️) next to any player to save them to your Favorites for rapid access when building slips. 

    • Refer-a-Friend: Secure a 10 dollar site credit for every friend you refer. Your friend simply needs to register using your username as a referral code, deposit at least 10 dollars, and play through that amount. Note that you must use the referral credit in a contest before withdrawal.

    • Multiplier Boosts & Specials: Underdog regularly offers boosted payouts and discounted player projections. Keep in mind that any extra winnings generated specifically from the boost or special are awarded as bonus funds, requiring a standard 1x play-through before they can be cashed out.

    How to Play on Underdog

    2

    Make Your Selections

    If you enter a Draft, you will take turns picking players for your roster against other users. If you are playing Pick'em, you must choose at least two players from different teams and decide if they will go Higher or Lower than their listed stat projection.

    Set Your Entry Amount

    Decide how much of your withdrawable cash or bonus entries you want to put on the line for that specific contest.

    Betting Options & Sports Market Coverage on Underdog

    While Underdog is not a sportsbook like FanDuel or DraftKings, they do have some entertaining and rewarding daily fantasy games for users to try out.  

    Underdog Best Ball Tournaments

    Users draft players for their roster in a snake draft to compete against other users for prizes at the end of each paid entry period. The players that users draft will gain points based on their performances in their respective sport. The prizes are determined on how much is pooled in each contest by the users.

    Pick'Em Contests

    Pick 'Em is a game type that's as easy as it sounds: users pick the over/under on certain players' stats for that days games. They must choose from a minimum of two different teams to submit their bet. Players can have fun choosing, for example, NBA players' PTS + RBS + ASTS for the matchup that night that they are looking at.

    Daily Drafts

    Users can join daily drafts by clicking on the 'drafts' section of the website. Players compete in the sport they choose. Examples would be NHL matchups that night, NFL playoffs, et cetera. The entry and prize amount in Underdog contests varies, but they are usually low stakes. 

    Battle Royale

    Underdog’s Battle Royale format differs from a standard fantasy contest in a few unique ways. Upon entering, you will get to pick players in a snake draft against six to twelver other users. However, you aren’t just competing against that group; you are competing against every user in every group for a specific time period.

    Underdog Top Features

    Underdog Pick'em Strategy: Standard vs. Flex Play

    Let's talk strategy! When you're putting together your Pick'em tickets on Underdog, knowing exactly when to choose "Standard" versus "Flex" is a total game-changer for your bankroll.

    Here is how I like to break it down:

    • Standard Play (Going All-In): This option means you need a flawless ticket. If you pick three players, all three have to clear their projections for you to see a dime. The upside? The payouts are massive. I usually save this for smaller, deeply connected picks—like pairing a point guard's assists with his favorite center's points.

    • Flex Play (Building in a Safety Net): Think of this as your built-in insurance policy. If you put together a five-pick slip and one of your players just has an off night, you still get paid! The overall return is a bit smaller, but the peace of mind is totally worth it.

    Flex is my absolute go-to for the NBA and NHL Finals right now. If a game turns into a blowout, your star player might get benched in the fourth quarter and miss his numbers. It's also a total lifesaver for baseball. Hitting a baseball is wildly unpredictable, so having that safety net means one bad night at the plate won't instantly trash your ticket.

    The Bottom Line: Stick to Standard when you have a super confident two- or three-leg combo, but definitely switch to Flex when you're building bigger tickets or mixing in different sports where crazy things happen!

    Why Underdog's 'Flex Play' is a Must-Have for June

    Switching on the Flex Play option on your Underdog entries is the best way to protect your picks. It gives you a built-in safety net so that one tough break doesn't ruin your entire night!

    While regular slips need every single pick to be flawless, going the flexible route lets you still win cash even if one of your predictions misses the mark. Here is why adding this awesome layer of insurance is such a game-changer right now:

    • Oops-Proof Payouts: Nobody is perfect! This feature gives you some much-needed wiggle room. If one player has an off night and misses their stat line, you still get to celebrate a nice little profit instead of losing your entry fee.

    • Playoff Chaos Insurance: The final rounds of the basketball and hockey playoffs get super crazy. Random foul trouble, strange rotations, or sudden blowouts can mess up the best-planned cards. Having that extra cushion keeps those wild moments from breaking your heart.

    • Dodging the Bullpen Hook: With the summer heat rising, baseball managers are super quick to pull their starting pitchers. If your favorite ace gets taken out early, this protective setting ensures your whole ticket doesn't go down the drain just because of a fast pitching change.

    • Stress-Free Teammate Pairings: It is super fun to link players from the same game—like a point guard's passing numbers with their center's scoring total. This option lets you build those cool combos while knowing you have a backup plan if the game script gets weird.

    I basically always click the Flex button whenever I'm building bigger slips with four or five picks. The top prize might be slightly smaller, but cashing winning tickets more often is totally worth it and keeps the fun going!

      Underdog Rivals: A Fresh Way to Play

      Let's talk about the awesome Rivals game mode! It’s a totally refreshing way to approach your daily tickets. Rather than guessing if one guy beats a set number, this format lets you pit two star athletes head-to-head.

      • Head-to-Head Battles: You could find a point guard matched up with a rival shooting guard in a tight race for points. You just predict who scores more!
      • Smart Point Spreads: To keep things fair, the app tosses in a helpful handicap. If a massive home run hitter battles a lead-off guy for bases, the smaller guy might get a +1.5 head start.
      • Reading Game Flow: Knowing the sport really pays off here. If you foresee a shootout where two stars answer each other all night, playing the spread is often smarter than trusting a basic stat line.
      • Pitching Showdowns: I absolutely love this setup for baseball. When two aces take the mound, picking who earns the most strikeouts saves you from guessing exact totals. You just need your guy to beat the adjusted number.

      Mixing this format into your daily routine is a fantastic way to switch things up, especially when the normal daily projections feel a bit too tight to trust!

      ⚽ Best Ball Draft: The World Pup

      If you want a winning edge on Underdog this summer, it’s time to shift your focus to the pitch and jump straight into The World Pup—Underdog's awesome $10 Best Ball tournament for the 2026 World Cup

      In this insane tournament, you get to jump into a fun, fast-paced snake draft against five other managers to build an epic 11-player squad. The best part? There is zero lineup maintenance. The app automatically counts your highest-scoring stars every single week as you hunt for a chunk of the massive prize pool, which features a cool $30,000 grand prize for first place!

      You can enter up to 150 times before the opening whistle blows, going through four unique tournament rounds where finishing at the top of your group moves you forward. 

      How the Format Works

      The tournament starts with 28,200 entries divided into 4,700 six-person groups during the Group Stage. The top performers advance through multiple rounds:

      • Round 1: Group Stage (6-person groups)
      • Round 2: Round of 32 through Round of 16 (8-person groups)
      • Round 3: Quarterfinals through Semifinals (5-person groups)
      • Round 4: 235-player final group during the World Cup Final

      The third-place match doesn't count toward scoring.

      Best Ball Scoring Format

      After drafting, rosters are locked for the entire tournament. There are:

      • No waivers
      • No trades
      • No substitutions

      Each week, Underdog automatically inserts the highest-scoring eligible players into the starting lineup, meaning managers never need to set lineups manually.

      Roster Construction

      Each roster consists of:

      • 1 Goalkeeper
      • 1 Defender
      • 1 Midfielder
      • 2 Forwards
      • 1 Flex
      • 6 Bench spots

      Managers should prioritize depth because player performances are automatically optimized each week.

      When you're picking your defenders, midfielders, and forwards, you can gain a major advantage by turning sharp tournament insights into winning draft strategies:

      • Target Group L Standouts: The experts are loving Croatia and England to totally dominate their group stage matchups. Grabbing key playmakers from these two squads gives your team an incredibly safe scoring floor right out of the gate in Round 1.

      • Lock Down High-Volume Goal Scorers: Keep a close eye on creative wingers like Bukayo Saka, or hunt for amazing value with dynamic targets like Belgium's Jérémy Doku, Czech Republic's Patrik Schick, or Bosnia's Dženan Zukić to anchor your forward slots.

      • Stack Up the Tournament Favorites: Powerhouses like France and Brazil are projected to make deep runs all the way to the final rounds. Loading up on their top stars ensures your roster stays active and high-scoring when the field shrinks later in the tournament.

      • Find Those Hidden Gem Playmakers: Look for under-the-radar assist leaders like Julian Ryerson or breakout potential from surprise countries like Egypt to give your tournament rosters a totally unique edge over the rest of the field!

      As someone who plays DFS daily, I can tell you firsthand that one of the most confusing parts of the game right now is figuring out exactly what you are allowed to play depending on where you are sitting. DFS regulations vary wildly across state lines—so even if you can download the app, you might not have access to every game mode.

      Pro Tip before you dive in: If you live in a state where Pick'em isn't allowed but Drafts are (like New York or Ohio), don't sweat it! Using your ACTION promo code on Best Ball tournaments or daily snake drafts is still one of the highest-value ways to build a bankroll on the platform.

      Who Is Underdog For?

      Sports fans constantly ask if this platform justifies their time and money. The answer relies entirely on your personal schedule and playing style. If you love grinding through salary cap spreadsheets all day, you might want to look at traditional sites. If you prefer rapid entry generation, this application shines.

      The interface serves users who prefer drafting a Best Ball roster during a quick break. It also satisfies data-driven players who enjoy isolating player projection totals instead of managing complex lineups.

      • The Speed Drafter: Snake drafts here work incredibly fast. You enter a contest, make your selections, and finish. Zero salary constraints exist to slow you down.
      • The Data Analyst: If you track obscure baseball metrics or hockey shooting percentages, the Pick'em lobby fits perfectly. You simply decide between higher or lower on specific stat lines.
      • The Time-Constrained Fan: Best Ball offers a true hands-off experience. You draft a roster, and the system automatically optimizes your starting lineup each week. You skip the waiver wire drama entirely.

      What Are Users Saying About Underdog? 

      To get a fair spread of thoughts on the app, we asked beginner and expert fantasy players their thoughts. Newbie Joe Beguiristain had this 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.

      Stephen Pierce, a seasoned fantasy player, had this to say:

      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 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 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 has been a great DFS option for all of us who play on these each day!

      Responsible Gaming & Spending Controls at Underdog

      Playing daily fantasy sports should always be about having fun and sweating the games. Underdog gets that, and they’ve built in some helpful tools right inside the app to make sure you play responsibly and stay within your comfort zone.

      • Deposit & Entry Limits: Set your own caps on how much cash you can deposit or play daily, weekly, or monthly. It’s an easy way to make sure you stick to your budget.

      • Time-Outs: Sometimes we all need a quick breather. You can hit pause on your account for a set amount of time until you're ready to come back.

      • Self-Exclusion: If you decide you need to step away from the app entirely, you can use the self-exclusion list. This locks your account and completely stops all of those promo emails and notifications.

      • State-Mandated Deposit Limits: Keep in mind that certain states enforce their own maximum deposit limits. Currently, Massachusetts is capped at $1,000 per 31 days, Maryland at $5,000 per 31 days, and Tennessee at $2,500 per 31 days.

      • Account Safety: Underdog encourages users to routinely reset their passwords and actively monitor their transaction and payment histories. You can also manually lock your account if you suspect someone else has gained access.

      • Parental Controls: Underdog strictly verifies that all users are of legal age. However, if a minor improperly uses a parent's financial information to create an account, parents are urged to contact support@underdogfantasy.com immediately for account closure and appropriate security measures.

      And remember, if you or a friend ever need some help managing your play, Underdog makes it easy to find support by linking directly to resources and hotlines like 1-800-GAMBLER right in the app.
