How Underdog Bonus Entries Work
Bonus Entries are promotional credits that can be used on eligible fantasy contests. They cannot be withdrawn as cash, and any winnings earned from them are handled under the terms shown in your account.
Check the promotional balance before playing, since Underdog may attach a use-by date or contest restriction to the credit. Also, Fantasy Bonus Entries cannot be used for Underdog Prediction Picks, a peer-to-peer prediction game where users make over/under predictions on player stats and compete for cash payouts, as it uses separate balances, disclosures, and eligibility rules.

What to Play With Your Underdog Bonus Entries
Once the $50 in Bonus Entries lands in your account, mid-August gives you a lot to point them at. MLB is deep into its regular-season stretch run, with a full slate most nights as playoff races tighten, so there are fresh Pick’em lines on hitters and pitchers almost every day. Underdog’s Higher/Lower format fits that well, since you’re just deciding whether a player finishes above or below a posted projection on stats like hits, total bases, strikeouts, or runs.
Football is back too, with the NFL preseason underway and coaches getting their first live looks at rookies and depth players. Preseason projections can be softer than the regular season, so check the latest inactives and expected snap counts before you lock in a slip, since starters usually sit or play only a series or two.
If you want a faster way to sort the board, PickLabs can filter projections by sport and surface the strongest value across the day’s Pick’em contests, but more on that later.
Underdog Game Types
Underdog offers a lot of formats within the same app, though the available options depend on your state.
Pick’em
Choose whether a player will finish Higher or Lower than a posted statistical projection. Entries can include several selections, with the potential return changing based on the format, number of picks, and lines chosen.
Rivals
Rivals compares two players in the same statistical category. One player may receive a handicap, so the pick is based on their adjusted result rather than the raw stat alone.
Champions
Champions is a peer-to-peer fantasy format available in certain states. Here, entries compete against other users instead of being graded directly against the operator.
Drafts and Best Ball
Draft contests let users build fantasy rosters against other players. In Best Ball, Underdog automatically counts the highest-scoring eligible players each week, so there are no lineup changes after the draft.
Prediction Picks
Prediction Picks is Underdog’s prediction-market product, where users can make picks on sports and other event outcomes in a federally regulated environment. It runs separately from the fantasy contests tied to the
Underdog highlights that some entries can advertise payouts of up to 5,000x, though the actual payout shown on your slip will depend on the specific product, your location, and the selections you make.

The promotion isn’t available in Maryland, Michigan, New Jersey, New York, Ohio, or Pennsylvania.
Keep in mind that promo eligibility and game availability don’t always line up. Some states may allow certain formats like Drafts or Champions while limiting others. Underdog verifies your physical location each time you enter a paid contest to make sure you’re eligible.
Age requirements also vary by state. Most users need to be at least 18, but the minimum is 19 in Alabama and Nebraska, 19 in Colorado for select games, and 21 in Arizona, Massachusetts, and Virginia.
Underdog Deposit and Withdrawal Options
Underdog accepts a lot of deposit methods, including:
- Credit and debit cards
- Apple Pay
- Google Pay
- Trustly
- PayPal
- Venmo
The options displayed can vary by account and location, and the minimum deposit for the
Eligible withdrawal methods include debit cards, PayPal, Venmo, and Trustly. Interchecks is no longer available.
Underdog recommends allowing 48 to 72 hours for withdrawal processing. After that, your bank or payment provider may take additional time to post the funds, and first-time withdrawals can be delayed if identity verification is required.
Underdog App Review
Underdog brings its fantasy contests, drafts, and prediction markets together in a single account, which makes it pretty convenient once you’re inside the app. The app is clean and easy to use, and switching between sports or different game types only takes a couple of taps.
The entry builder is especially useful if you like comparing multiple projections at once, since it keeps everything organized in one place. Best Ball is another standout for players who enjoy drafting teams but don’t want the trouble of managing weekly lineups.
That said, there’s a bit of a learning curve at first. With Pick’em, Champions, Drafts, and Prediction Picks all operating under slightly different rules, it can feel a little overwhelming until you get used to it. One simple habit that helps is double-checking the product label before entering a contest. This avoids most of the confusion, especially when using promos or credits that don’t apply everywhere.
As of August 16, 2026, the Underdog Sports app holds a 4.8 rating from about 313,000 reviews on the Apple App Store, and a 4.6 rating from roughly 31,700 reviews on Google Play.
Is Underdog Legit?
Underdog launched in 2020 and has quickly become one of the better-known fantasy sports platforms in the U.S. In a funding round in March 2025, the company was valued at $1.225 billion before additional investment came in.
It runs state-regulated fantasy contests and also operates a federally licensed prediction-market exchange. What you can access depends on where you live, and each product comes with its own rules and disclosures.
Underdog Promos for Existing Users
If you already have an account, you’ll notice that promotions change fairly often. These offers aren’t always the same for everyone and can include things like discounted projections, boosted payouts, protected entries, or small bonus credits.
It’s always worth checking the Promotions tab before you build an entry, since that’s where active offers will show up. Each one will spell out the details clearly, what sport it applies to, the minimum entry size, when it expires, and how any bonus or return is paid out.
Just keep in mind that promos don’t stick around for long. Some only last a few hours, and others are tied to a single slate, so it’s best not to assume something you saw earlier is still available.
Finding Underdog Picks With PickLabs
FantasyLabs’ PickLabs is a tool built for Underdog players who want a faster, more data-driven way to build entries without manually sorting through every projection. It’s designed for users who are trying to identify value across player props and pick’em-style contests, especially those who rely on projections and analytics to guide their decisions.
Users can use PickLabs to filter projections by sport, compare player lines side by side, and quickly assemble multi-pick entries based on the strongest projected edges. Instead of starting from a blank slip, the tool surfaces options that already meet certain value thresholds, making it easier to spot potential +EV plays in seconds.
That speed and structure help streamline decision-making, but they don’t eliminate the need for caution: projections can change throughout the day, so users still need to double-check everything before locking in a slip. Injuries, lineup updates, weather conditions, and late scratches can all move the board in real time, so a strong play in the morning may not look the same by game time.
PickLabs is designed to help you build and evaluate your picks, but it shouldn’t be used blindly. Always confirm the latest information before finalizing your betting slip, since late-breaking news can quickly impact a pick’s value.
Responsible Gaming at Underdog
Underdog includes several built-in responsible gaming tools to help users manage their play responsibly directly within the app and website. You can set deposit limits, entry limits, and time-based limits directly in your account settings, allowing you to control how much you spend and how often you play.
The platform also offers cool-off periods and self-exclusion options if you need to take a break from playing. These can be activated at any time and adjusted through your account, depending on the level of restriction you choose.
