Underdog Promo in September 2026
Plus 50% First-Time Deposit Match up to $1,000 (State Dependent)
Make the Correct Prediction Pick to Score Your Payout
Spreads, Totals, Moneylines, and Parlays, all on Underdog
Starting August. 28, Underdog is rolling out a new offer called “Keep Your Million.” It’s Underdog’s free-to-play survival game, and every eligible customer — all new users, plus most existing users — will receive a virtual $1,000,000 bonus pot to play with.
Football is back on, and so is your chance to instantly call yourself a millionaire… then try and keep it that way. Underdog drops the stash straight into your account with “Keep Your Million.”
Here’s how it works: players pick a question (for example, will Patrick Mahomes throw for higher or lower than 275 passing yards?), then split their million by dragging a slider to divide the pot between Higher and Lower — anywhere from 100% on one side to an even 50/50 split, since all the money has to go somewhere.
Once a pick is submitted before the game starts, it’s locked in and can’t be changed. When the game settles, the player keeps whatever they put on the winning side, and that amount becomes their new pot for the next question. Players make picks across up to 20 questions total, and if they survive all 20, they cash out whatever’s left in Underdog bonus funds. This is a limited-time offer. To get started, use our promo code: BETLSRPM and sign up for a new account today.
On top of this offer, Underdog Predict is also providing a first-time deposit match. New users who qualify for Underdog’s 50% Deposit Match, up to $1,000 in Bonus Funds, must make a minimum $10 first deposit, with the bonus equal to 50% of the deposit up to the $1,000 maximum—meaning a $2,000 deposit is required to receive the full $1,000.
The Bonus Funds are credited within 72 hours and, under the current terms, both the original deposit and bonus must be played through 1x within 14 days before the resulting funds can be withdrawn. The offer is for new users only; availability and the maximum bonus vary by state.
Here’s how Underdog’s current offers break down by state group:
- States with JUST Predictions offer (Keep Your Milly only): CT, HI, ID, IA, LA, ME, MT, WA
- States with Pick’Em and Predictions offer (Keep Your Milly + 50% Deposit Match up to $1,000 in Bonus Funds): AL, AK, AR, CA, DE, DC, FL, GA, IL, IN, KS, MN, MO, NE, NH, NM, NC, ND, OK, OR, RI, SC, SD, TX, UT, VT, VA, WV, WI, WY

Underdog Fantasy review
Since its debut in 2020, Underdog has been steadily gaining traction in the competitive fantasy sports industry. The company has differentiated itself from the industry giants by offering a variety of games.
Traditionally, daily fantasy sports have used a salary cap model in which users build the best possible lineup while sticking to the game’s budget. Underdog has taken things in a different direction with games like best ball and battle royale.
In addition, you’ll find more than just daily games at Underdog. There are contests that span an entire week, and even season-long offerings via its best ball contests. Let’s take a closer look at Underdog.
User interface
The team behind the scenes at Underdog has a wealth of experience. That becomes apparent from the first look at the user interface. Once you’ve set up your account, you’ll find a clearly laid-out lobby.
Navigation is simple, as there are dedicated prompts for each available sport and type of game. In the account section, you’ll find links to game rules, customer support options, payment information, and more. Another feature is the built-in news feed.
There are feeds available for top sports. You can scroll through and view the latest headlines with ease and expand an item to read more when something catches your eye. Overall, the interface at Underdog is user-friendly.
Customer service
Underdog offers customer support via email or by submitting a request directly through the website or app. Once logged in, you simply click to access the account section and locate the “contact support” tab.
During our test run, we ran into some trouble logging in on the website after accessing the mobile platform without issue. We sent an email to customer support and received an instant reply that the request was received.
A representative followed up and addressed the issue, which was a simple fix that was cleared up quickly. While we can’t promise that support will always deliver in such a prompt fashion, Underdog gets a thumbs-up on the support front in this case.
Deposits and withdrawals
Underdog sticks to the basics with payment options. You can find the cashier section by clicking on the dollar sign icon. That’ll bring you to the deposit screen, where you can choose from PayPal or credit/debit card.
For withdrawals, you can select PayPal or Interchecks. If you choose the latter, you’ll receive an email notification about how to enroll and be able to receive an e-check. Deposits process instantly, while withdrawals tend to receive approval quickly on Underdog’s end.
The speed at which you receive your entries will depend on the method you choose. Compared to other leading fantasy sports sites, Underdog has fewer payment options, but covers the bases with a couple of easy-to-access methods.
Game selection
At Underdog, you’ll find a menu of games that have proven popular with users since its inception:
- Best ball: Participate in snake drafts with other users to compete for prizes. Choose your players when it’s your turn, and then “set it and forget it,” as the platform will choose your optimal scoring lineup. Field sizes, buy-in amounts, and length of the game vary, and there are also larger tournaments available.
- Pick’em: There are two formats to choose from. For rivals, you choose which of two players you think will score more fantasy points. Higher/lower gives you a range of player benchmarks to choose from, similar to wagering on player props. You can make two to five picks for both types of contests.
The Underdog lobby has two distinct tabs for draft and pick’em games, so you can easily find what you’re looking for. We’ll take a closer look at the types of games later in this guide, including the rules, scoring, and available options for both formats.

Current promotions at Underdog
Underdog does offer a handful of promotions, including “Scorchers,” indicated by a chili pepper icon. These promos work as payout boosts for Underdog pick’em selections.
Ranking the Underdog Fantasy app
Underdog offers an app for iOS and Android devices. In general, the app has received positive reviews, with an average score of 4.8/5 on the Apple App Store, based on over 89,000 reviews, and an average rating of 4/5 on Google Play, based on over 5,000 reviews.
You can play best ball leagues, battle royale leagues, Underdog pick’em, and other rotating contests for real money prizes.
User experience
The DFS platform is popular. It’s simple and easy to navigate, with large text and buttons for a no-frills, intuitive experience whether you’re playing a draft league or building a pick’em entry. The platform is less sophisticated than some of its peers, with fewer stats and features than an app like Sleeper or PrizePicks, but some users, particularly beginners, will probably welcome the simpler user interface.
Placing a entry
Underdog Fantasy includes several features you would expect to find at most major DFS apps. Here is how it stacks up against a couple of popular options in the US Daily Fantasy Sports market.
| Features | Underdog Fantasy | FanDuel DFS | DraftKings Pick6 |
| Parlays | Yes (as Pick’ems). You combine 2–6 player stats. All must hit (Standard) or some can miss (Insured). | Yes (as SGPs/Hub). Offers Same-Game Parlays and a “Parlay Hub” for pre-built DFS lineups. | Yes (as Pick Sets). You build sets of 2–6 picks. Functions like a peer-to-peer parlay. |
| Boosted payout | Yes. Frequent “Multiplier Boosts” and “Pick’em Specials” (e.g., a QB needing only 0.5 yards). | Yes. Offers daily “Odds Boosts” (10%–40% extra) on popular DFS contests and markets. | Yes. Offers “Boosted Payouts” and rewards through the Dynasty Rewards program. |
| Stats | Simplicity. Highly visual “Higher/Lower” interface with clear historical performance bars | Data Density. Deep integration of advanced game previews and real-time player news/trends. | Peer Insights. Shows how many other players are picking “More” vs “Less” on a specific stat. |
| What could be better? | Social Features. Lacks a robust community/chat aspect compared to apps like Sleeper or Dabble. | Interface Clutter. The app is feature-heavy, which can be overwhelming for new DFS players. | Multi-Sport Picks. Currently restricts Pick Sets to a single sport; cannot mix NFL and NBA in one set. |
| What stands out in a good way? | “The Best Ball King”: They revolutionized the “set it and forget it” draft. You draft a team once, and the app automatically starts your highest-scoring players each week. It’s perfect for people who love drafting but hate the weekly chore of checking injury reports and setting lineups. | “The Beginner’s Safety Net”: FanDuel is widely considered the most “fair” for new players. They offer Beginner-Only Contests where you are physically blocked from playing against “sharks” (pros with thousands of wins), giving you a much better chance to learn without losing your bankroll instantly. | “The P2P Advantage”: Unlike other pick’em apps where you play against “the house” (fixed odds), Pick6 is peer-to-peer. This means if you pick a “sleeper” stat that most other people ignore, your share of the prize pool can be significantly larger. It adds a layer of game theory that isn’t present elsewhere. |
| Customer support | 24/7 Live Chat, Email, Help Center, Twitter (@UnderdogSupport). | 24/7 Live Chat, Email, Callback Request, Twitter (@FanDuel_Support). | 24/7 Live Chat, Email, Callback Request, X/Twitter (@DKSportsbook). |
| Android and iOS app ratings | iOS App Store: 4.8 / 5 (267k+ reviews) Android: 4.4/5 | iOS App Store: 4.9/5 (1.8M+ reviews) Android: 4.7/5 | iOS App Store: 4.8/5 (27k+ reviews) Android: 4.1/5 |
Underdog Fantasy desktop
Some users may prefer not to download an app, and Underdog gives you the option to play directly in your web browser. The Underdog website is compatible with all major browsers (Chrome, Safari, Edge, Firefox, etc.) and offers all of the same features as the app.
Banking options at Underdog
There are three options for depositing money at Underdog. You can use a credit card, debit card, or PayPal, all of which require a deposit of at least $10 and process instantly.
When withdrawing, Underdog customers can request payment via PayPal or receive an e-check. As with depositing, there is a $10 minimum in effect. PayPal payments can take up to two days to process, whereas e-checks can take up to four days. Although credit and debit cards are supported for deposits at Underdog, you cannot withdraw funds from your Underdog account using a credit or debit card.
Customer support at Underdog
In general, Underdog customer support is responsive and should reply to any queries quickly and professionally. However, contacting Underdog support is relatively inconvenient compared to other DFS platforms. There is no phone number available, which would be a useful addition to the Underdog platform.
Contact options for Underdog customer support
To contact Underdog customer support, the best way is to head to the Underdog website, scroll to the bottom of the page and click “Contact support.” From there, you will be redirected to a page labeled “Submit a ticket.”
