Draft your dream team with Underdog
There are multiple Underdog sign-up offers, depending on which state you’re in, and they’re generally pretty decent. The main one we’ll focus on here is the sign-up bonus, also known as the welcome bonus. The sign-up bonus, 'Play $5 Get $50 in bonus entries,' gives you a $50 in bonus entries if you spend at least $5 after your first deposit.
There’s an upper limit of $50 in bonus entries. You can deposit more than $5 if you want to, but just bear in mind that anything above that amount won’t increase your sign-up bonus. Keep this detail in mind, as going over the limit won't benefit you.
You’ll need an Underdog promo code to claim this offer. Don't worry, though, as it's easy to find and you’ll see it listed on their website. From what I can tell, the exact code you’ll need to use will depend on the state you’re joining from
When you compare the Underdog promo code to other bonuses, like the DraftKings fantasy promo code (which only gets you $50 in bonus picks), you’ll see that it's not bad at all - it's actually a pretty solid offer.

What are the Terms & Conditions on the Underdog Bonuses?
As with anything, there are certain rules about what you can and can’t do when it comes to the Underdog promo code. The only things you really need to worry about are your eligibility in terms of age, residency, and physical location. Then there’s the playthrough requirements: you need to play through the bonus funds 1x before they can be withdrawn. It’s all standard stuff, really - and that's good and means there's nothing unusual here.
Generally, you need to be 18 or older to use the Underdog promo code; in Alabama and Nebraska, you must be 19 or older. The same goes for some games in Colorado, to be able to play certain games. Folks in Arizona, Massachusetts, and Virginia must be 21 years of age or older. You also need to live in one of the states where Underdog operates.
Take note that this offer is not available in Maryland, Michigan, New Jersey, New York, Ohio, or Pennsylvania. These restrictions vary depending on which product we’re talking about, so I’d highly recommend heading to their website to check their state map. Full Terms and Conditions apply.
While I’ve triple-checked all the details here for accuracy, things change all the time, and what’s true now might not be tomorrow—especially across different states. So it’s best to read the small print on the UF website to understand how the rules apply to you.

My top 5 tips for using the UF bonus
Now you know how to enter the Underdog bonus code and use the funds, but how can you make the most of them? There's a lot to consider, I know, but don't worry, I've got you covered. Here are my top five tips to help you.
💰 Be ready to deposit
Once you set the wheels in motion, signing up, entering the promo code, you’ll need to make your first deposit to actually be able to enter contests. So, be ready with your chosen payment method. At the moment, you can use PayPal, Trustly, Visa, Mastercard, and Apple Pay.
I You should always stick to your budget, no matter what the bonus says. Play responsibly, and never spend more than you can afford to lose. Having trouble controlling your spending or gameplay? There's help available, and we recommend checking out the responsible gaming tools page on the Underdog website, it's really useful.
🎉 Spread your bonus across contests
Variety is the spice of life, so don’t feel restricted to entering a single contest with your bonus funds. Feel free to explore the different contests first! You can spend it on Best Ball drafts, Daily Drafts, and Pick'em games, provided you’re in an eligible territory. You can also spend your bonus dollars on Battle Royales. In these daily fantasy sports, you draft a six-player team for the week that’s made up of one quarterback, one running back, two wide receivers, one tight end, and one flex position.
📅 Make sure to play the whole bonus
I’m sorry to bring it back to the T&Cs, but listen up, because it’s important: you’ve got to play your entire initial deposit AND the welcome bonus before you can withdraw any of the promotional entries.
⏰ Make your plays within 14 days
From the moment you enter the Underdog promo code and make your first deposit, you’re on the clock. You’ve got 14 days from that point until Underdog will take your bonus funds away if they’re not used, so make sure you use them before they expire.
🏈 Play what you know
This one might sound obvious, but it’s worth mentioning because it can make a huge difference in your winnings potential. If you want to make informed decisions, the trick is playing what you know. Stick to your sphere of sporting knowledge, whether that’s backing your home team, selecting your favorite athletes in your line-up, or drafting an NFL roster based on calculated picks.
Underdog promotion fast facts
Got no time to lose? Fine by me—less time reading this Underdog review means more time studying form, making your picks, and watching the game. Here are the answers to your burning questions, delivered faster than Mason Miller’s Wild Card Series postseason pitch.
1. Can I get the bonus if I already signed up?
No, sadly not. This is a new user bonus we’re talking about after all. It’s designed to attract new sign-ups, so if you’re already signed up, the offer’s not meant for you. That being said, if you literally just signed up and have not deposited yet, and you forgot to enter the code, try contacting the customer support team to see if they can add it manually. The team there are really friendly, and they'll try to help.
2. Why isn’t the bonus appearing in my account yet?
Hold tight, as these bonuses can take up to 72 hours to show in your account. Channel your inner Juan Soto and try to master the art of patience. Provided you’re eligible and you’ve done everything you’re supposed to, your bonus will arrive soon. Feel free to use your deposited funds in the meantime, and always reach out to customer support if you have any concerns.
3. What can I use the bonus funds for?
Once your account has been credited with the promotional fantasy bonus entries, it’s time to get out there and make your plays! Before you do, let’s be clear: you can only use the promotional funds on fantasy entries, not on picks. However, you can use your bonus for entries called Combos, which are a mix of event contract futures and fantasy sports contest entries.
4. How do I choose to use bonus funds instead of my deposited funds?
To get the bonus, you need to deposit funds. That means you’ll end up with some of your own deposit in your account, and some promotional credit. For example, if you deposit $50, you’ll get $25 for using the Underdog 50% matched deposit promo code, giving you a total of $50. So how do you tell what’s what?
It’s simple, actually. If you have both types of funds and you can't select which to use, the bonus funds will be used first. This is automatic. However, if you see the option to choose between the two types of funds, you can use either. Simply select your preference before making your play.
5. Is there a no-deposit bonus?
I’m afraid not, as there is no Underdog no-deposit offer available. You'll need to deposit at least $10 to qualify for the 50% first deposit match, or if you're looking to claim the current offer featured on this page, simply place a $5 entry to unlock $50 in bonus entries.

More great offers at Underdog
Right now, there’s no loyalty or VIP program at Underdog. Although that’s not ideal, before you go running off to look for a FanDuel fantasy promo code, let me save you some time—they don’t have one either. Now that’s not to say there aren’t fantasy sports sites out there with loyalty programs. But you can’t expect them as a prerequisite.
Anyway, what we’re really interested in is the value a brand provides. Good news is, the Underdog promo code offers brilliant value, even if you can’t achieve a fancy VIP status. And there’s no shortage of other promotions you can take advantage of at Underdog too. Let me tell you about the main ones to take note of:
Refer-a-friend
If you want to recommend the Underdog platform to your friends, make sure they use your link to sign up. You can find your unique referral link in your account. When they click it, the promo code box on the signup form should automatically populate with your username (if it doesn’t, they can just add it manually).
When your friend deposits $10 or more, you get a credit to your player account. The amount varies, and you have to play it through at least once before it can be withdrawn. Another detail to keep in mind: you can only add one Underdog promo code when signing up. So if your friend adds your username, they may not be eligible for the normal deposit-match welcome bonus.
Money-back assurance
Now, Underdog really stands out for this one. If you make your first play and decide you’re not satisfied with the product or experience, there’s basically a get-out clause. You can claim a refund on your first contest (up to $100) within 48 hours of entering. Just as long as you haven’t withdrawn any winnings, and you close out your account afterward.
Pick’em and Champions Promos
There are a variety of promotions within the Pick’em and Champions products at Underdog. These change regularly, so keep your eyes peeled for new offers in the app, especially around NFL season and in the lead-up to the NBA season.
For example, with the Gimme Pick promotion, one of your roster selections can be regarded as a winning pick, even if they bomb in the real-world event. This is also known as Gimme Pick. With the No Sweat promotion, you get credits if your pick doesn’t win. ‘Boost’ increases the winning value of a Pick’em entry. Then there's ‘Discount’ and ‘Bonus Entry’, which do what they say on the tin. You may also see promotions like Unlock, Split the Pot, Play and Get, and Slash the Stat from time to time.
Even more bonuses!
I wasn't kidding when I said you won’t be short on promotions at Underdog… here are some others you might come across:
- Multiplayer Boosts
- Pick’em Specials
- Supercharge
- Playback Program
- Gimme Picks Contests
- Extra Gimme Play
- Discount Player
- Pick’em Rescues
- Swipe Games Winnings Boost
- Deal Reveal
- Dawg Bowl Pick'em Live Event
The Underdog promo code is rock-solid

Underdog promo code FAQ
Is there a playthrough requirement for the Underdog bonus?
Yes, you will need to play with your bonus funds if you want to keep them. The official playthrough requirement is 1x. Think of it like this: you can only withdraw winnings. For example, if you get $50 in bonus entries through the Play $5, Get $50 in bonus entries bonus, then you will need to play that entire amount before being able to withdraw any resulting entry wins.
What happens if I don’t use my Underdog bonus funds within the time requirement?
You have 14 days to play your bonus, which Underdog calls the Turnover Period. If two weeks pass and you still haven’t used your bonus, Underdog can reclaim it. Even though you may lose your promotional funds, you can withdraw any winnings that you made during those 14 days.
Can I create new Underdog accounts to get multiple bonuses?
Nope! If you’re found to have duplicate accounts, you’ll end up with a red card. Not only will you lose your bonus funds, but you could be subject to other ‘adverse action’ as per the Fantasy Underdog Ts and Cs. They have systems that flag this sort of behavior. Bottom line: don’t do it.
What’s the maximum amount of bonus I can get at Underdog?
It depends on the offer that is activated, you can get up to $1,000 in bonus funds when you use the Matched deposit Underdog promo code. It just depends on how much you deposit.
Where do I add the Underdog promo code?
You’ll find the Underdog promo code on their website, and you add it when you sign up for an account. When you fill in the form, there’s a box that says “Promo code or username” where you enter the code - it’s right under the box where you add your date of birth.
