Best Monday Action to Target with Your First $5 Entry
If you’re using our Underdog promo code
Instead of forcing an entry on a random spring training baseball game, we recommend targeting tonight’s pivotal NBA matchups with major playoff implications, or securing early-week value on the impending “First Four” college basketball games. Here are a few notable high-liquidity markets to target today:
- Lakers @ Rockets (3/16)
- Spurs @ Clippers (3/16)
- NCAA “First Four” Matchups (Early Board Look-Aheads)
This is a mathematically sound way to qualify: deposit $10, build any $5 entry tied to tonight’s biggest games, and let the $50 in bonus entries hit your account.
Our Underdog Expert Candor: Underdog’s withdrawal process for standard funds is reliable, but it can take 2-3 business days to hit your bank account.

Best Underdog Free Picks for Monday’s Slate
I bet you want to extract the maximum value from your Underdog promo code offer today, so here’s my advice.
I always use the FantasyLabs’ DFS Pick’em Simulation Tool for Underdog when making my entries. It’s one of the best fantasy sports tools to view picks by operator and league, so whether you want Underdog NHL or Underdog NBA picks for tonight’s slate, you’re covered.
This tool is paid, but I share a few free picks every day so you can get a taste of what it’s like to have expert insights. Here are the latest data-backed NBA projections for Monday, March 16th, 2026 (subject to line movement):
- Nic Claxton to get LOWER than 21.5 Points, Rebounds and Assists (67% WIN PCT, 10% EDGE)
- D.J. Wagner to get LOWER than 1.5 Rebounds (63% WIN PCT, 9% EDGE)
| NAME | SPORT | TEAM | TYPE | PROJ | PICK | WINPCT | EDGE |
|---|---|---|---|---|---|---|---|
| Nic Claxton | NBA | BRK | Points, Rebounds and Assists | 21.5 | Lower | 67% | 10% |
| D.J. Wagner | CBB | Arkansas | Rebounds | 1.5 | Lower | 63% | 9% |
Other sites such as RotoGrinders also have Underdog picks tools to help you make the right MORE or LESS picks. Not surprisingly, RotoGrinders features a similar Underdog promo code for new users that you can check out.
Underdog Promos for Existing Users: NCAA Tournament Edition
Once you’ve maximized your initial $50 welcome bonus, Underdog keeps the value flowing with a daily cadence of valued promotions for existing users throughout the NCAA Tournament.
One of our absolute favorite ways to build a slip is utilizing the “Gimme Pick” (often called a free square). Underdog will routinely slash a star player’s projection down to just 0.5 points for marquee Monday night NBA games, giving you a mathematically massive advantage to anchor your Pick’em entry.
Keep in mind Underdog’s Pick’em isn’t one universal product. In several states, the Pick’em format you’ll see is Champions (peer-to-peer) rather than the classic “vs the house” style, so you must adapt your slip construction accordingly to beat the market.
Here are other deals we track daily in the Underdog lobby:
- Refer-a-Friend Bonus: Get extra bonus cash when your friends sign up and deposit ahead of the tournament.
- Multiplier Boosts: Look out for “More Money Mondays” where your payout potential is amplified.
- No Sweat Tokens: Get your entry fee refunded in bonus cash if your slip loses.
- First Quarter Splash: Exclusive NBA promos that grade your picks based solely on first-quarter performance.

Is Underdog Legit in 2026?
With the rapid explosion of daily fantasy sports, it’s completely natural for prospective players to ask: Is Underdog legal and legit? The short answer is a resounding yes.
Founded in Brooklyn in 2020 by Jeremy Levine, Trevor John, and Brandon Stakenborg, Underdog has rapidly evolved from a scrappy startup into a massive DFS industry juggernaut.
Backed by heavyweight investors like Mark Cuban, Kevin Durant, Adam Schefter, and BlackRock, the platform commands a valuation well over $485 million.
Beyond the impressive financial backing, Underdog operates with strict regulatory compliance across the U.S. heading into 2026.
They utilize bank-grade AES encryption to protect your personal data and funds, and they provide robust responsible gaming tools so players can easily set deposit limits, entry limits, and session timeouts.
Underdog App Review
Our team has played Underdog contests across different sports ever since the operator joined the daily fantasy industry.
We’ve both deposited and withdrawn funds without a hitch. The entire process has been smooth, and the Underdog app offer arguably the best user experience as far as gaming products are concerned in large part thanks to a clean layout.
But don’t just take our word for it…
The Underdog mobile app is among the highest-rated apps. It has an average rating of 4.7 stars across 23,000+ reviews in the Google Play Store and 236,000+ reviews in the App Store.
Players cite the user-friendly interface, strong customer service team, and exciting new game types among the reasons they love Underdog.
Is everything flawless? Naturally, it’s not. Underdog is still in its growth phase. For example, we’d appreciate it if Underdog could enhance its college football services, perhaps by including player cards with photos. However, these are minor issues.
Underdog iOS Reviews
Here’s what an Apple user had to say about the Underdog app:
“I just started playing on Underdog and it is the best new daily fantasy option out. DraftKings and fanduel have become so overloaded with the professionals that enter thousands of lineups with computer algorithms that make it almost impossible to win as a casual fantasy player. The small group snake drafts are awesome to level the playing field and they even have a safety measure to ID and remove any collusion between players on drafts… I would recommend everyone that wants a fun way to get back into daily fantasy without having to worry about beating computer algorithms…”
– Leeward904
Underdog Android Reviews
The Underdog app is also popular among Android users, with one saying the following on the Google Play Store:
“Really enjoy the UI but the slow drafts are brutal when there are inattentive players. It should put them on autopilot if they don’t make their pick and they can turn it off when they finally check the app again. Support is timely with their responses, had an issue and they had a solution to me in about an hour”
– S. Williges
Expert Underdog Desktop Review
I had to go out of my way to use the Underdog desktop site for this review, as I’m a die-hard mobile app user.
To be perfectly candid, while the mobile app is elite, the desktop experience leaves a bit to be desired for high-volume DFS players. All of the projections are neatly organized, and you can filter by league or pick type. However, the entry builder sits clunkily on the page. When you expand the bottom window to check your correlations or slip payouts, it obscures all of the available board picks.
For Drafts, the info within each contest window also seems a little clustered. It’s a functional interface, but if you are seriously hunting for closing line value and tracking fast-moving injury news ahead of the NCAA Tournament tip-offs, the desktop latency is a flaw. The mobile app is vastly superior for serious players.
Underdog Beginner Review
“As a newcomer to daily fantasy sports apps, I was a bit hesitant to try Underdog. However, I really enjoyed predicting player performances. It can seem a bit intimidating if you’re a new sports fan, but picking your team is super easy.
I found Underdog’s Best Ball Tournaments to be the easiest to manage since I only have to draft my team and leave it there. It really is a more “hands-off” approach, which is perfect for beginners like myself. I’m definitely looking forward to trying more game types with my friends.” – Alicia Grimes
Underdog Expert Review
“As much as I enjoy playing traditional daily fantasy sports on sites like DraftKings and FanDuel, optimizing lineups with a set budget requires a lot of time and research. Underdog keeps things more casual and fun by specializing primarily in snake draft and pick’em contests.
Snake drafts are fun because you don’t have to worry about budgets; you can just draft the best player available for your squad when it’s your turn to make a selection. And the pick’em format is great for turning your hunches on player performances into potentially big wins.
As an experienced sports bettor who shops for the best odds, I often find Underdog lines that are different from the competition, which can provide extra value. For example, if the major sportsbooks have Ja’Marr Chase at Over/Under 87.5 receiving yards and Underdog has it at 88.5, I have a better chance of hitting the Under here.
Whether you are obsessed with fantasy sports like me or are a casual sports fan, you should have plenty of fun trying out the different game modes at Underdog.” – FantasyLabs’ Dave Consolazio
Underdog: From Early Beginnings to Current Offerings
Underdog was started in 2020 in Brooklyn, New York by Jeremy Levine, Brandon Stakenborg, and Trevor John. Its popularity has exploded since then having not only grabbed a handful of noteworthy investors but also received stark recognition from players. Underdog’s app is user-friendly with a clean layout, earning a rating of 4.8 stars in the App Store and a slightly lower 3.8 rating on the Google Play Store.
Underdog is different than many other of the best DFS sites. Instead of competing against sharks in salary-cap formats, Underdog levels the playing field with snake drafts.
Those drafts can cover an entire season’s worth of games – also known as best ball – or they can span just one single day. These drafts can feature just two people or as many as 12. In the biggest best ball formats, 12-team leagues are combined to create some of the largest payouts in fantasy.

Our exclusive
Available Fantasy Sports & Contest Types at Underdog in 2026
Underdog started out strictly as a football product, but it has since expanded into almost every major market. In fact, it’s hard to find an active sport that isn’t currently available on the Underdog app.
As we head into the spring, the lobby is hyper-focused on the hardwood and the ice. Open the Underdog app today to find fantasy sports such as:
- NBA (Late-season playoff pushes)
- College Basketball (Gearing up for March Madness)
- NHL
- Golf (PGA Tour)
- Soccer (EPL & Champions League)
- Tennis
- Esports
- WNBA
- Racing
- MMA
- Boxing
- MLB (Spring Training & Futures)
Underdog even has more niche sports like NASCAR DFS, allowing you to make picks pretty much year-round.
The contest types on the Underdog app can be split into two main categories: Drafts and Pick’em.
FantasyLabs Note: Out-of-season sports like the NFL and College Football are available for long-term Best Ball drafts, while novelty events like the MLB HR Derby return in the summer.
Underdog Drafts & Best Ball Tournaments
Snake drafts are the foundation of Underdog’s massive success, highlighted by their industry-leading Best Ball format. As we transition from winter sports into spring, these drafts remain highly active.
This mode lets you draft a complete, season-long (or single-day) fantasy roster with zero in-season roster management required. Once your draft concludes, the system automatically optimizes your starting lineup every single week or slate, ensuring you always capture the highest possible points without having to set daily lineups.
Pick’em
If you prefer testing your sports knowledge against the house rather than drafting against other users, Underdog’s Pick’em lobby is where you want to be.
The mechanics are beautifully simple: Underdog sets a statistical projection for a player (e.g., quarterback passing yards, NBA rebounds, or MLB total bases), and you simply choose whether the player will finish “Higher” or “Lower” than that number.
You can also explore “Rivals” matchups, which pit two players against each other with a handicap. For example, in some NBA action, Luka Doncic might be -4.5 points against Shai Gilgeous-Alexander. Doncic would have to score at least 5 more points than Gilgeous-Alexander to win that specific pick.
To build an entry, string together between two and eight picks. Your payout multiplier climbs with every pick you add, ranging from 3x for a standard two-pick slip all the way up to a massive 325x if you hit an eight-pick entry.
If you want to try another DFS pick’em site, check out the FanDuel Picks promo code.
Champions
Underdog knows that states are cracking down on fantasy games, particularly pick’em-style contests. Luckily, the major DFS app has a response to this: Champions contests. Champions is a peer-to-peer game that lets you play against other users rather than the house. After building a roster of 2-8 players and entering a tournament, you can earn Champions Points based on your players’ performance. The user with the most Champions Points by the end wins!

How do I deposit on the Underdog app?

How quick are Underdog drafts?
Underdog offers two different speeds for their drafts: fast and slow. Fast drafts feature a 30-second timer per pick, so drafts are completed really quickly. In an 18-round football draft, the draft will take a maximum of 108 minutes. In reality, most drafts will likely be completed in less than an hour. They’re perfect if you’re sitting around and looking to bang out a draft quickly. Slow drafts replace the 30-second timer with an eight-hour timer. That means the drafts will be completed over the course of multiple days or weeks. They’re the solution for those looking to draft leisurely or looking to draft as many teams as possible.
How fast does Underdog payout?
Underdog pays out winnings exceptionally quickly. It usually takes around 20-30 minutes after all the games in your Draft or Pick’em contests are completed. If you’re looking to withdraw funds, it usually takes around 2-3 business days.
Can I play Underdog in California?
Yes, you can play Underdog in California! The Drafts contests and Champions contests are available to California players, with the latter being the peer-to-peer version of pick’em.
Is Underdog available in Texas?
Yes, Underdog Texas offers real-money pick’em games and Drafts contests. It’s a good alternative to sports betting, as the Lonestar State has yet to legalize gambling.
