How We Reviewed Underdog Fantasy
For this Underdog Fantasy review, we evaluated the platform based on its signup flow, available contest types, posted promo information, state eligibility guidance, app experience, banking options, withdrawal rules, support resources, and comparison with other DFS platforms such as DraftKings, FanDuel, and PrizePicks.
Because DFS rules, contest availability, and promotional terms can change by state, we also look for whether a platform clearly explains where each game type is available. Underdog is strongest when the user checks the app or state eligibility page before entering paid contests, especially if they are looking for Pick’em, Drafts, or newer prediction-style formats.

What Is Underdog Fantasy?
Underdog Fantasy is a real-money daily fantasy sports platform that launched in 2020 and has become especially well known for Best Ball drafts and simple Pick’em-style fantasy contests. Rather than building a traditional season-long fantasy team that requires constant lineup management, many Underdog contests are built around drafting once, making quick player-stat selections, or entering short-form fantasy competitions.
The platform is most appealing to users who want fantasy sports contests that are faster and cleaner than traditional season-long leagues. Best Ball players get an automated lineup experience, while Pick’em users can build entries around player projections across sports such as football, basketball, baseball, hockey, soccer, golf, tennis, MMA, racing, and esports.
The important caveat is that Underdog does not look the same for every user. Your available games, minimum age requirement, and contest menu depend on your location. That makes state eligibility one of the most important things to confirm before you deposit or enter a paid contest.
Underdog Fantasy Promo Code & Bonus – Rating 5/5
New Underdog Fantasy users may be eligible for a welcome offer when signing up through ATS. The current offer shown on this page is powered by our live promotion shortcode, which helps keep the displayed bonus amount updated when terms change.
Before claiming any offer, check the latest bonus terms, minimum deposit requirement, eligible contests, playthrough rules, and expiration details. Promo offers can vary by state, account status, and campaign.

The bonus is one of the stronger parts of the Underdog experience, especially for users who already planned to try Best Ball or Pick’em-style fantasy contests. That said, the offer should not be the only reason to sign up. The better question is whether Underdog has the contest type you want in your state.
Is the Underdog promo code worth using?
Yes, for eligible new users. The promo code is worth using if you are already interested in Underdog and understand the offer terms. It is less useful if your state does not support the contest type you want to play, so check availability first.
Refer-A-Friend Program
Underdog may also offer referral promotions from time to time. These offers typically require a new user to sign up with a referral code, meet a minimum deposit or entry requirement, and satisfy any bonus rules before bonus funds can be used or withdrawn. Referral terms can change, so review the latest conditions inside your account before relying on a specific reward amount.
Boosts, Specials & Pick’em Promotions
One reason Underdog is popular with Pick’em users is that it often builds promotions around adjusted projections, boosted payouts, or special entries. These promos can make the app feel more active during major sports seasons, but they should still be treated as promotional offers with specific rules.
When a boosted or special projection is available, check whether winnings are paid as withdrawable cash, bonus funds, or another promotional balance type. This matters because bonus funds often carry different usage rules than regular account funds.
Banking Options at Underdog Fantasy – Rating 3.5/5
Underdog Fantasy supports real-money paid fantasy contests in eligible locations. Users can deposit funds, enter paid contests, and withdraw eligible winnings after identity verification and any bonus-related requirements are satisfied.
Banking is one area where Underdog is solid but not elite. The available options are simple and familiar, but the platform does not offer the same broad cashier menu that some larger DFS or sportsbook-linked brands provide. You can read more in our full guide to Underdog banking options.
Deposit Options
Underdog commonly supports card and PayPal deposits, though the exact options shown in your cashier can depend on your account and location.
- Debit card or credit card: Users may be able to deposit with major card brands. The cardholder name should match the Underdog account holder.
- PayPal: Eligible users may be able to deposit through PayPal by logging into their PayPal account during checkout.
Underdog may require identity verification before deposits, withdrawals, or paid contest entries are fully available. This is normal for real-money fantasy sports platforms.
Withdrawal Options
Underdog withdrawals are usually handled through available cashier methods such as PayPal or payment processors that support bank transfer, check, or prepaid-card options. For a deeper breakdown, see our guide to Underdog payouts and withdrawals.
Withdrawal timing can vary based on review, verification status, payment method, and weekends or holidays. If bonus funds are involved, those funds may need to be used according to the promo terms before any related winnings are eligible for withdrawal.
Does Underdog Fantasy actually pay?
Yes. Underdog Fantasy pays eligible winnings after identity verification and once any applicable bonus or playthrough requirements have been met. Users should make sure their account details are accurate, as mismatched personal or payment information can delay withdrawals.
How long does Underdog Fantasy take to pay out?
Underdog withdrawals are typically reviewed before release, and final timing depends on the withdrawal method. PayPal may be faster than check-based options, while bank-related methods can take additional business days after approval.
Mobile App & User Experience – Rating 4.5/5
The Underdog Fantasy app is one of the platform’s biggest strengths. It is built around quick navigation, simple contest discovery, and a clean entry flow, which matters for users who want to draft teams or build player-stat entries without fighting through a crowded interface.
Underdog is available on iOS and Android, and users can also access the platform through a mobile or desktop browser. The best experience is usually inside the app, especially for users who want to move quickly between drafts, Pick’em entries, account settings, and promotions.
From a usability perspective, Underdog does a good job of keeping the core product simple. Draft rooms are easy to follow, player cards are clean, and contest menus are generally easier to understand than some more crowded DFS lobbies. Performance can still depend on device, connection, and traffic around major contests.
Underdog Fantasy App Ratings From Other Users
Underdog is listed in both major app stores. Because app ratings and review counts change frequently, users should check the current App Store or Google Play listing before relying on a specific rating number.
| Store | What To Check | Download |
|---|---|---|
| 📱 Google Play | Current rating, recent reviews, device compatibility, and app update history | Google Play |
| 🍎 App Store | Current rating, age rating, recent reviews, and iOS compatibility | App Store |
Underdog Fantasy Games & Contests – Rating 4.5/5
Underdog’s main appeal is its game mix. The platform is strongest for users who want Best Ball drafts, quick fantasy entries, and player-stat contests rather than a traditional daily salary-cap DFS experience.
Best Ball
Best Ball is Underdog’s signature format. Users draft a roster before the season or tournament begins, and Underdog automatically scores the best-performing eligible players each week. There are no waivers, trades, or start/sit decisions after the draft.
This makes Best Ball appealing to fantasy players who enjoy drafting but do not want the weekly management burden of a traditional league. Entry fees, roster size, draft size, scoring format, prize pool, and maximum entries vary by contest.
Battle Royale
Battle Royale contests are shorter draft-based contests, often built around a specific week or slate. Users draft against a small group, but final standings are usually measured against the broader contest field rather than only the users in the draft room.
This format works well for users who like drafting but want something faster than a full-season Best Ball tournament.
Pick’em
Pick’em is the quick-entry fantasy format many users associate with Underdog. Instead of drafting a full roster, users make selections based on player projections or player-vs-player style outcomes. Available Pick’em formats and payout structures can vary by state.
The key thing to understand is that Pick’em availability is not universal. Some users may see Pick’em in their app, while others may only see Drafts or other eligible game types based on location.
Predictions and Newer Formats
Underdog has also expanded beyond its original draft-focused product with newer prediction-style games in some locations. These formats may include team-based or player-based selections, but availability and rules vary heavily by state. For that reason, users should treat the in-app contest menu as the source of truth for what they can actually play.
For SEO and user clarity, this matters because Underdog is no longer just a Best Ball app. It is still best known for drafts and Pick’em-style fantasy contests, but the user experience now depends more than ever on location and product availability.
Sports Coverage – Rating 4/5
Underdog covers a broad range of sports, with the strongest appeal around major U.S. leagues and fantasy-friendly player-stat markets. NFL and NBA users will usually find the deepest experience, while availability for smaller leagues and niche sports can vary by season and contest type.
Depending on your location and the time of year, Underdog may feature contests or entries tied to sports such as:
- Football: NFL and college football
- Basketball: NBA and college basketball
- Baseball: MLB
- Hockey: NHL
- Soccer: Major domestic and international competitions
- Golf: PGA contests
- MMA: UFC and combat sports selections when available
- Tennis: ATP and WTA coverage when available
- Racing: NASCAR and F1 where offered
- Esports: Selected esports contests depending on availability
This is a strong sports menu for DFS users, but it is not the same thing as a traditional sportsbook menu. Underdog is better evaluated as a fantasy contest platform with different game types by state.
Safety & Security at Underdog Fantasy – Rating 4.5/5
Underdog Fantasy is a legitimate real-money fantasy sports platform where permitted. The main trust signals are its account verification process, published contest rules, payment and withdrawal procedures, responsible-play messaging, and state-specific eligibility restrictions.
From a user safety perspective, the most important thing is understanding what Underdog offers in your state. A platform can be legitimate overall while still limiting specific products in certain jurisdictions. That is why we do not recommend assuming that Pick’em, Drafts, or prediction-style formats are available everywhere.
Where Is Underdog Fantasy Legal?
Underdog Fantasy availability depends on your state, age, and game type. Some users may have access to Drafts, Pick’em, and newer prediction-style formats, while others may see only certain products or no paid contests at all.
For the most complete breakdown, use our dedicated guide to Underdog Fantasy legal states. That page is the better place for a full state-by-state table because availability can change and because product-level differences are too important to oversimplify on the main review page.
As a general rule, users must meet the minimum age requirement in their state and be physically located in an eligible jurisdiction. Some states have higher minimum age requirements than 18, and some products may be restricted even where other Underdog contests are available.
Is Underdog Fantasy legitimate?
Yes. Underdog Fantasy is legitimate, but users should understand that legitimacy is not the same as universal availability. The safest way to use Underdog is to confirm your location eligibility, review the rules for the contest you want to enter, and understand how bonus funds work before depositing.
Customer Service & Support – Rating 3.5/5
Customer support is one of the weaker parts of the Underdog experience compared with the quality of the app and contest product. The help center covers many common topics, but users looking for instant live support may find the options more limited than they would like.
Users can typically contact support by email or through a support request form. Common support topics include account verification, location eligibility, deposits, withdrawals, bonus funds, contest rules, and app troubleshooting.
The help center is useful for basic questions, but the lack of prominent live chat or phone support is why we rate customer service lower than the app, bonus, and contest categories.
How Does Underdog Fantasy Compare to Other DFS Sites & Apps?
Underdog Fantasy is not trying to be the same kind of DFS app as every competitor. It is more focused on drafts, Best Ball, and fast fantasy entries than traditional salary-cap DFS. That makes it excellent for some users and less ideal for others.
Underdog Fantasy vs DraftKings
DraftKings is the broader DFS brand, especially for users who want salary-cap contests, large daily slates, and a more traditional DFS lobby. Underdog is cleaner and more specialized, with a better fit for Best Ball drafts and users who want fewer lineup-management decisions.
Choose DraftKings if you want a deeper traditional DFS ecosystem. Choose Underdog if you prefer drafts, automated Best Ball scoring, and a simpler fantasy entry flow.
Underdog vs FanDuel
FanDuel has a long DFS history and a wide user base. It is a stronger fit for players who want a familiar salary-cap DFS experience with contests across major sports.
Underdog is more focused. Its biggest edge is that the app feels purpose-built around drafts and fast fantasy contests. Users who want a less crowded interface may prefer Underdog, while users who want classic DFS contest variety may prefer FanDuel.
Underdog vs PrizePicks
PrizePicks and Underdog overlap most clearly in Pick’em-style fantasy contests. PrizePicks is more narrowly associated with projection-based entries, while Underdog also has a major draft and Best Ball identity.
Choose PrizePicks if you want a platform built almost entirely around player projection entries. Choose Underdog if you want both Pick’em-style contests and a stronger draft product, especially around football season.
How To Sign Up & Get Started
Signing up for Underdog Fantasy is straightforward, but users should check state eligibility before depositing. The app may show different contests depending on your location.

Final Verdict: Is Underdog Fantasy Worth It?
Underdog Fantasy is worth considering if you want a DFS app built around Best Ball, drafts, and quick fantasy entries. It is especially strong for football users, draft-focused players, and anyone who prefers a cleaner mobile experience over a crowded traditional DFS lobby.
The biggest reason to choose Underdog is its product focus. Best Ball is easy to understand, the app is polished, and the entry flow is simple. The biggest reason to hesitate is availability. Depending on your state, you may not have access to every Underdog product, and some users may find the banking and support options more limited than expected.
Our verdict: Underdog Fantasy is legit and one of the better DFS apps for Best Ball and Pick’em-style fantasy contests, but it is not equally strong for every user. Check your state, review the current bonus terms, and make sure the contest type you want is available before depositing.
