How the Deposit Match Bonus Funds Work
The $100 arrives after your qualifying entry settles, not when you deposit. So the sequence is deposit, enter, wait for the contest to finish, then collect.
What lands in the account varies by location. Some states get bonus funds, which sit in your balance; others get Bonus Entries, which cover the entry fee on a contest rather than adding spendable credit. The difference matters: with a Bonus Entry, a winning contest pays the profit in cash but the promotional entry fee itself isn’t returned.

Where to Use Your Underdog Bonus This Week
NFL Week 4 starts Thursday with Steelers at Browns at 8:15 p.m. ET. Sunday is the much bigger slate, with 14 games spread from morning through Sunday Night Football. It starts early with Colts vs Commanders in London at 9:30 a.m. ET, then rolls into the usual afternoon windows before Lions at Panthers closes the day at 8:20 p.m. ET.
Falcons at Saints wraps up Week 4 on Monday at 8:15 p.m. ET. If I were starting with NFL projections, I’d look at Sunday first simply because there are more games and players to sort through. Thursday and Monday give you much smaller single-game slates by comparison.
College football and the MLB postseason give you other player pools around the NFL slate, depending on what Underdog makes available in your location.
If Pick’em or Champions is available where you are, I’d use PickLabs to narrow down the board, then confirm every projection in Underdog before submitting. Available sports and game types vary by location, and the live number shown in the app is the one that counts.
Underdog Game Types
What shows up in your Underdog lobby depends on your location.
Pick’em and Rivals
Pick’em lets you choose Higher or Lower on player-stat projections. Rivals uses two players in the same statistical category, sometimes with an adjustment added to one side. You may see Rivals projections within Pick’em-style products rather than as a completely separate part of the app.
Champions
Champions keeps the player-projection format but puts your entry into a peer-to-peer contest with other users. Correct selections earn Champions Points, and the final payout depends on your performance relative to the other winning entries in the pool.
Drafts and Best Ball
Draft contests use fantasy rosters rather than Higher/Lower projections. Best Ball requires no weekly lineup changes after the draft because Underdog automatically counts your highest-scoring eligible lineup. Other draft formats can include shorter contests and tournaments.
Games
Underdog’s Games tab now includes Streaks, Ladders, Swipe and Crash, among other formats. Streaks starts with two picks and can run to 11 correct picks in a row. Ladders uses three to five selections with three scoring rungs on each pick. Crash is a live MLB contest built around individual pitches and plate appearances.
Keep in mind some of these products are still rolling out, so you may not see every one in your account.
Prediction Picks
Prediction Picks. Uses event contracts traded on CFTC-regulated exchanges. Depending on the contract, the exchange may be Underdog’s UDX or another registered DCM accessed through Underdog Predict. These products follow different rules from Underdog’s fantasy contests, and the LABS welcome offer doesn’t apply to them.
Some products show potential returns of up to 5,000x, though the number shown on your entry depends on the format, selections and any applicable modifiers.
Where Is the Underdog Promo Code Available?
The
Eight states have Underdog’s Predictions product only: Connecticut, Hawaii, Idaho, Iowa, Louisiana, Maine, Montana, and Washington. The fantasy welcome offer isn’t available in those states.
Underdog has no product in Nevada or New York.
Promo eligibility and game availability don’t always line up. Some states allow Drafts or Champions while limiting other formats, and Underdog checks your physical location every time you enter a paid contest.
Age minimums apply platform-wide, not just to this offer. Across eligible states, the floor is 18, with three exceptions: 19 in Alabama and Nebraska, 19 in Colorado for some games, and 21 in Arizona, Massachusetts, and Virginia.
Underdog Deposit and Withdrawal Options
Underdog accepts credit and debit cards, Apple Pay, Trustly, PayPal and Venmo for fantasy deposits. Google Pay is also being rolled out for Android users. The platform minimum deposit is $10.
Withdrawal options can include Visa or Mastercard debit cards, PayPal, Venmo, Trustly online banking and Apple Pay tied to an eligible Visa debit card. Debit card, PayPal, Venmo and Apple Pay withdrawals usually require you to have deposited with that method first. Trustly doesn’t require a previous Trustly deposit.
The minimum withdrawal is $10 unless your remaining account balance is below $10, in which case you can withdraw the balance that remains.
Underdog says withdrawal requests normally go through a 48-to-72-hour processing window. Depending on the method, your bank can add another one to three business days after that. Remember weekends, holidays and additional account checks can stretch the calendar, so a Friday request doesn’t always move at the same pace as one placed on a Tuesday.
Underdog App Review
Underdog keeps fantasy contests, drafts, Games and Prediction Picks in one app, so you don’t need to switch between different platforms. The products don’t all share the same balance, though. Prediction Picks placed through Underdog Predict use a separate futures account from your Underdog Fantasy funds, although you can transfer money between the two when authorized.
The entry builder adds player lines as you go and updates the potential payout before you submit, which makes it easier to compare lots of projections in the same stat category and see how each pick changes the entry.
Best Ball is a good fit if you enjoy drafting a team but don’t want to spend every Sunday adjusting your lineup.
The main learning curve comes from the fact that Pick’em, Champions, Drafts, Games and Prediction Picks all follow different rules. Check which product you’re using before submitting an entry, especially when you’re playing with promotional credit. Just because you have a Bonus in your account doesn’t mean it can be used on every option in the lobby.
The Underdog Sports app holds a 4.8 rating from about 323,000 ratings on the Apple App Store and a 4.6 rating from roughly 33,900 reviews on Google Play, checked October 2026.
My Experience With Underdog
A $20 Apple Pay deposit was usable instantly, with no hold before I could enter a contest, though I’ve had this account for years, so I can’t speak to first-time verification timing.
On August 27 I built a four-pick Standard card for $5 at 10x, all MLB strikeout props: Gerrit Cole over 5.5, Jacob Misiorowski over 8.5, Chris Sale over 6.5, Yoshinobu Yamamoto over 6.5. Sale and Yamamoto cleared comfortably at 11 and 8. Cole finished on 5, Misiorowski on 6. Two from four, which on a Standard entry pays exactly the same as zero from four.
That’s worth understanding before you reach for Flex. A four-pick Flex pays on 3-of-4, not 2-of-4, and building all four legs from one volatile stat is the shape most likely to land you at two, the one place Flex offers nothing.
Withdrawals have been the most reliable part. A $25 request submitted at 7am on August 19 landed roughly 36 hours later, inside Underdog’s stated 48-to-72-hour window, with no verification hold or payment review.
Is Underdog Legit?
Underdog launched in 2020 and has become one of the better-known fantasy sports platforms in the U.S. On July 30, 2026, London-listed IG Group agreed to acquire the company for up to roughly $1.3 billion, about $1.1 billion in upfront enterprise value plus an earnout tied to 2026 performance.
The deal is expected to close in late 2026 or early 2027, pending regulatory and antitrust approval, so Underdog continues operating independently in the meantime.
It runs state-regulated fantasy contests and, since July 18, 2026, its own CFTC-licensed exchange for prediction markets, Underdog holds the DCM, DCO, and FCM registrations needed to list and clear contracts in-house.
What you can access depends on where you live, and each product comes with its own rules and disclosures.
Underdog Promos for Existing Users
What you do get is a rotating set of promotions that aren’t identical for everyone. Expect discounted projections, boosted payouts, protected entries and 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.
Some run for only a few hours or a single slate, so check the tab rather than assuming an offer you saw earlier is still live.
Finding Underdog Picks With PickLabs
PickLabs is built for Underdog players who’d rather not sort through every projection by hand. It surfaces value across player props and Pick’em contests for anyone working from projections rather than gut feel.
Filter projections by sport, compare player lines side by side, and assemble multi-pick entries from the strongest projected edges — rather than starting from a blank slip, you get options that already clear a value threshold.
The speed doesn’t remove the need to check your own work. Injuries, lineup updates, weather, and late scratches move the board in real time, so a play that looked strong in the morning can look very different by kickoff. Confirm the current line before you lock an entry.
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.
If entries are starting to feel like a problem for you or someone you know, help is available 24/7 through the National Problem Gambling Helpline at 1-800-GAMBLER, or 1-800-MY-RESET.
