What Is Underdog and How Does It Work?
Underdog is a daily fantasy sports (DFS) and pick'em platform, not a traditional casino. I play on it for NFL and NBA player props. You pick whether a player will go over or under a projected stat line, like points or rebounds.
For the current offer, use Underdog.
The platform launched in 2020 and is operated by Underdog Sports, LLC. It works in 40 U.S. states, Washington D.C.and Canada (except Ontario). That's a wider reach than some competitors like PrizePicks, which is blocked in about 8 states.
You don't bet against the house like a sportsbook. Instead, you're playing in contests against other users. Your entry fee goes into a prize pool, and the top finishers get paid out. It's a different model than DraftKings or FanDuel, focusing purely on player and team prop picks.
I signed up back in 2022. The appeal was the simplicity. No need to build a full roster or worry about salary caps. Just pick 2-5 players, choose over/under, and see if you're right. It's a much lower barrier to entry than traditional DFS.
That said, the legal model is under fire. Arizona regulators moved to revoke its license in late 2025 over its prediction market offerings. There's also a class-action lawsuit floating around alleging it runs unlicensed bets. Not a great look for a platform asking for your money.
Compared to other social sportsbooks, Underdog is more niche.
It doesn't have the massive sports coverage of DraftKings or the parlay options of FanDuel. It's a pick'em specialist. If that's your game, it's one of the bigger names. If you want moneyline bets or live betting, look elsewhere.
Underdog Bonus & Promotions
Underdog's welcome bonus is a $5 free bet. When you sign up and make a first deposit, you get this credit to use on any pick'em contest.
Now, here's where it gets messy. The site itself currently promotes "Play $5, Get $75 in Fantasy Bonus Entries" with code UDPROMO. Third-party sites report everything from "Get $50" to "Get up to $1000 matched." This inconsistency is a red flag. From playing here, I've seen the offer change multiple times.
The $5 free bet is straightforward. You deposit, you get $5 in site credit. You use it to enter a contest. Any winnings from that bonus are subject to a 1x playthrough requirement before you can withdraw them. That means you need to bet the winnings one more time.
Deposit Match Bonus
There's also talk of a deposit match. Some help articles and bonus aggregators mention a 50% match up to $1,000. I haven't personally triggered this, and it's not advertised front-and-center. If it exists, the terms would be. Always assume any matched funds have playthrough rules attached.
Promo Codes & Ongoing Offers
The active promo code is UDPROMO. Enter it during sign-up. Beyond that, Underdog isn't big on reload bonuses or daily login rewards. You won't find a progressive calendar like on sweepstakes sites such as Pulsz.
They run occasional tournaments and leaderboard contests with prize pools. These are usually tied to big sporting events. The prizes are decent, but the competition is fierce. Don't expect easy money.
The wagering requirement is the standard 1x for bonus funds.
This is lower than the crazy 40x you see at some crypto casinos, but it's in line with other DFS apps. Just remember: you can't withdraw bonus winnings until you've re-wagered them once.
Compared to DraftKings' "Bet $5, Get $200" or FanDuel's similar offer, Underdog's $5 free bet looks small. But those big offers are for traditional sportsbooks, not pick'em. For a pure pick'em platform, a small free bet is pretty standard. PrizePicks offers a "Deposit $10, Get $100" deal, which is more generous on paper.
Underdog VIP & Loyalty Program
Here's the short answer: Underdog doesn't have a public VIP or loyalty program. I've played for 3 years and haven't seen one.
There are no tiers, no rakeback, no dedicated host, no weekly reload bonuses. Nothing. This is a huge gap compared to almost every other real-money gaming platform I use.
Stake US has a detailed 10-tier VIP system with monthly bonuses. Even social sportsbooks like DraftKings have reward points and tier status. Underdog offers zero ongoing incentive to keep playing after you've used your welcome bonus.
This tells you something about their business model. They're not trying to cultivate high-volume players. They're going for the casual user who drops in for a few NFL props on Sunday. If you're someone who wagers thousands a month, you get nothing extra for your loyalty. No host to help with issues, no cashback on losses, nada.
It's not worth "grinding" on Underdog because there's nothing to grind towards. Your rewards are purely the contests you win. For a serious player, this is a major con. You're better off at a platform that values your action.
For comparison, BetRivers gives 0.01% rakeback on every bet. Fliff offers a 10% weekly bonus on losses. Underdog's 0% reward structure feels outdated in a market where even DFS rivals have loyalty perks. They're leaving 100% of potential player retention value on the table.
Underdog Games & Offerings
Underdog's game types are its core product: Pick'em, Drafts, Champions, Team Picks, and Prediction Picks. These are all proprietary, not from external software providers.
Pick'em is the main attraction. You select 2 to 5 players. For each, you choose if they'll go over or under a stat line. All your picks must hit to win. It's essentially a parlay on player props. The payout multiplies with each pick you add.
Drafts are a snake-style draft against other users. You pick a team of players within a salary cap. Champions is a tournament format where you pick one player per day to outscore opponents. Team Picks let you bet on team totals instead of individual players.
Prediction Picks are markets on non-sporting events, like awards shows or stock prices. This is the product that got them in hot water with Arizona regulators.
Sports & Markets
They cover multiple sports. I mostly play NFL and NBA. The player prop lines are solid for those. You'll find projections for points, rebounds, assists, passing yards, touchdowns, etc.
They don't publish a total count of sports or leagues. It's not 15+ like DraftKings. It's focused on the major U.S. sports. You won't find extensive soccer, golf, or tennis markets here.
Bet Types & Features
The bet types are specific to their model: player picks, team picks, spreads, and totals. There's no traditional moneyline betting (picking a team to win outright). No live/in-play betting that I've seen. No early cashout options on your picks.
The odds/vig is built into the prize pools. Payouts are less than true odds because the house takes a cut from the entry fees. It's similar to a tournament rake.
Game selection is fine for what it is. If you love player prop parlays, it's a clean interface.
But if you want variety, slots, table games, live dealer, this isn't a casino. It's a single-product platform. For a broader gambling experience, you'd need to go somewhere else entirely.
To give you a real example, a 2-pick entry might pay 3x your entry fee. A 5-pick entry can pay 25x. That's a huge multiplier, but hitting 5 props in a row is statistically brutal. The house edge is baked into those long odds.
For a $10 entry, you're competing against hundreds of other players for a slice of the prize pool.
How Fast Are Underdog Payouts?
Underdog payouts take 48 to 72 hours for standard processing once requested. Withdrawals are free, which is a plus. The minimum you can cash out is $10.
Here's a table of their banking methods based on what I've found and used:
| Method | Type | Min Withdrawal | Processing Time |
|---|---|---|---|
| PayPal | Withdrawal | $10 | 24-48 hours (reported), 48-72 hours (official) |
| Trustly | Withdrawal | $10 | 48-72 hours |
| Visa/Mastercard/Amex/Discover | Deposit | Not specified | Instant |
| Apple Pay | Deposit | Not specified | Instant |
| Direct Bank Deposit | Deposit | Not specified | Instant |
I've used PayPal for withdrawals. The official line is 48-72 hours, but some Reddit users claim it's faster, under 30 minutes. My experience has been closer to the 2-day mark. Don't expect instant crypto payouts like you get at Stake or BetFury.
Deposits & Limits
Deposits are instant with cards or Apple Pay. I've done $20 without issue. There's no public info on maximum redemption amounts either.
KYC & Verification
You will need to verify your identity. This is standard for any regulated U.S. gaming platform. They'll ask for your SSN, address, and likely a photo ID. This happens before your first withdrawal. It's not a no-KYC crypto casino.
The processing time is slower than industry leaders. DraftKings and FanDuel often process in 24-48 hours. Underdog's 48-72 hour window is a bit of a lag. It's not terrible, but it's not fast.
The $10 minimum is reasonable.
It's higher than DraftKings' $5 but lower than PrizePicks' $20. The lack of fees is good. Overall, banking is functional but unremarkable. The speed is the main drawback.
One more detail: they don't support any crypto deposits or withdrawals. That's a 0 out of 5 for crypto fans. If you want to use Bitcoin or Ethereum, you need a different site entirely. Their banking list is limited to about 5 mainstream options.
Is Underdog Legit? Safety & Trust
Is Underdog legit? The answer is complicated. Technically, yes, it's a legal entity, Underdog Sports, LLC, operating in licensed jurisdictions. But the trust signals are flashing red.
The biggest red flag is the 1.3-star Trustpilot rating based on over 1,600 reviews. That's catastrophically bad. I read through pages of complaints. The dominant themes are account closures without explanation and funds being withheld after winning.
On Reddit (r/underdogfantasy), you see the same stories. Users report getting banned, especially after attempting a withdrawal or hitting a big win. The platform seems quick to flag "suspicious activity" and shut accounts down. This creates a real fear that you could win and never get paid.
They have responsible gambling tools: deposit limits and self-exclusion. That's a positive. The age requirement is 18+ in most states (19+ in AL, NE; 21+ in AZ, MA, VA).
Now, the legal issues. In December 2025, Arizona regulators moved to revoke Underdog's license related to its Prediction Picks markets. There's also a class-action lawsuit alleging the platform runs unlicensed bets. This regulatory scrutiny is a serious concern for long-term stability.
If you play here, do not keep a large balance. Withdraw your winnings regularly. The combination of a 1.3-star rating and account closure complaints means you should treat this platform with extreme caution.
The operator track record is short, they only launched in 2020. They don't have sister sites that I could find. Compared to a behemoth like DraftKings, which is publicly traded, Underdog feels like a riskier proposition.
The iOS app has a 4.8-star rating with 294K reviews, which is great for usability. But a nice app doesn't matter if you can't access your money. Trust is the foundation of any gambling site, and Underdog's foundation looks cracked.
For context, PrizePicks has a 1.5-star Trustpilot rating. So the whole pick'em niche seems plagued by trust issues. But Underdog's 1.3 is among the worst I've seen for a regulated operator. That's lower than many outright scam casinos operating for 3 months.
Customer Support
Underdog offers live chat through the "Contact Support" button in the app or your account tab. That's the primary channel.
They also have a help center at Help's website It's fairly for basic questions about how to play, deposit, or withdraw. The articles are clear.
What's missing? A published email address. A phone number. Stated support hours. From my experience and reading complaints, getting a real person to solve a complex issue, like an account closure, is where the system falls apart.
Many Trustpilot reviews mention support being unhelpful or unresponsive when accounts are frozen. The automated system might be fine for password resets, but for serious disputes, players feel gaslit.
There's no active community support channel like a Discord or official Telegram. The subreddit is user-run. Compared to a site like Stake US, which has 24/7 chat and a massive Discord, Underdog's support feels minimal and reactive.
If you have a simple question, you'll probably get an answer. If you have a problem with your account or a withdrawal, be prepared for a frustrating experience. This aligns with the overall trust issue. Good support builds confidence; weak support destroys it.
I tried the chat once with a basic deposit question. I got a bot response in 30 seconds, then a human agent took over in about 2 minutes. That's fine. But for account issues, players report waiting 48 hours for a generic reply that doesn't solve anything. That's the critical failure point.
Mobile Experience
The mobile experience is Underdog's strongest point. The iOS app has a 4.8-star rating from 294K reviews on the App Store. That's excellent.
I play almost exclusively on my phone. The app is clean, intuitive, and fast. Building a pick'em entry takes seconds. between contests, your history, and your account is smooth. It's definitely designed for mobile-first use.
There's also an Android app on Google Play. The feature parity with the iOS app and desktop site is complete. You can do everything on mobile.
The mobile browser experience is also solid if you don't want to download the app. The site is responsive and works well on both phones and tablets.
Performance is good. I've never had the app crash or lag, even during busy NFL Sunday windows. They push notifications for contest reminders and results, which is helpful.
For a pick'em platform, the mobile execution is near perfect. It's the one area where they clearly outshine some of their competitors. The app is so good it almost makes you forget the trust problems... almost.
Here are 3 specific things the app does well:
- One-Tap Picks: You can lock in a 5-pick entry in under 10 seconds from the main lobby.
- Live Tracking: During games, your pick'em card updates in real-time with player stats, no 30-second delay.
- Banking Integration: Depositing with Apple Pay is a 2-tap process that takes 3 seconds total.
Where Is Underdog Available? Legal Status
Underdog is available in 40 U.S. states, Washington D.C.and Canada (except Ontario). That's a pretty wide footprint.
The restricted U.S. states are the usual suspects for DFS: Connecticut, Hawaii, Idaho, Iowa, Louisiana, Montana, Nevada, New Hampshire, New York, and Washington. Always check their official site for the most current list, as regulations change.
In Canada, it's available except in Ontario, which has its own regulated market.
The age requirement varies: 18+ in most places, 19+ in Alabama and Nebraska, 19+ in Colorado for some games, and 21+ in Arizona, Massachusetts, and Virginia. Make sure you know your local law.
They do not allow VPN use to access from restricted states. Trying to bypass geo-blocks will get your account closed and any funds forfeited. This is standard practice but worth repeating.
Compared to DraftKings and FanDuel, which are available in roughly 45+ states for sports betting, Underdog's 40-state reach is slightly smaller but still substantial. For a pick'em specialist, it's about as good as it gets for availability.
The legal status is the shaky part. With Arizona's regulatory action and the lawsuit, the platform's future in some jurisdictions is uncertain. If you're in a state where they operate, you can play today. But there's more regulatory risk here than with an established, publicly-traded book.
Here's a quick list of 5 major states where Underdog is legal:
- California (DFS only)
- Texas
- Florida
- Illinois
- Pennsylvania
How to Sign Up at Underdog
Signing up is straightforward. Here's the step-by-step process I followed.
- Download the Underdog app from the App Store or Google Play, or go to their website.
- Tap "Sign Up." You'll need an email address and to create a password.
- Enter your personal details: name, date of birth, address. This is for age and location verification.
- Enter the promo code UDPROMO if you want the welcome bonus. Do this during sign-up.
- Verify your location. The app will use your device's location services. You must be physically located in a permitted state.
- Verify your identity. This usually involves providing the last four digits of your SSN. They might ask for a photo ID later, especially before your first withdrawal.
- Make a deposit. Choose your method (card, Apple Pay, etc.). The minimum isn't stated, but $20 works.
- The $5 free bet bonus should credit to your account shortly after your first deposit settles.
The whole process takes about 5 minutes if everything goes smoothly. The KYC (identity check) is the part that can cause delays if there's an issue. Have your ID ready just in case.
My tip: Use a real, verifiable identity. Trying to use fake info will get you banned fast. And remember, you can only have one account per person.
After you finish those 8 steps, you'll land in the lobby. You'll see 50+ live contests for the day. I recommend starting with a 2-pick entry for $1 just to see how it works. Don't jump into a $100 5-pick on your first try.
