Underdog consistently introduces attractive promotions, and the current Play $5, Get $75 in Bonus Funds offer immediately stood out to me. There is an official Underdog promo code tied to this deal, and below I explain exactly how the process works from start to finish.

To lock it in, click any of the Underdog banners featured on this page, register your account, make a $10 deposit, and enter $5 into any UF contest. I followed those same steps, and the $75 in bonus funds were credited to my account almost right away. From there, I was able to jump into Pick'em Contests, Battle Royale, Daily Drafts, and several other formats. Keep reading for a detailed breakdown of what happens next and how to maximize the offer.

Enjoy a generous deposit bonus at Underdog
Make the most of Underdog's new welcome offer

Underdog is fast becoming my go-to DFS site, and its clean UI is one of the highlights here, along with the focus on player projections and bonuses. Underdog sign-up offers are available for all new customers, followed by additional bonuses along the way. Top on my list that gives more with less has to be the welcome promo of Play $5, Get $75 in bonus funds, which is activated when you create a new account, deposit $10 or more and play $5 in your first Pick'em contest.

This is perfect if you're on a limited budget, although it's not available in all states, in which case a 50% deposit match promo of up to $1,000 will be available. Either way, as shown in my Underdog review, you'll get more to play with from the outset, so you can start exploring the NFL Pick'ems, NBA showdowns, and MLB slates. Getting the bonus is surprisingly straightforward - just follow the links in our banners, fill in the registration form, deposit $10 minimum, and play $5 on an Underdog contest. After that, you'll be awarded $75 in bonus funds. The bonus does come with a playthrough requirement, but since this is set at an easy 1x, it's hardly a concern. For comprehensive DFS platform reviews, visit our main daily fantasy sports page.

With the basics cleared, who qualifies for the bonus? You must be of legal age 18 years of age (19+ in AL, NE; 19 years of age in CO for some games; 21 years of age in AZ, MA, and VA) and located in a state where Underdog fantasy operates. The offer is not valid in MD, MI, NJ, NY, OH, and PA. Terms and Conditions apply.

How to use the Underdog bonus: step-by-step!

Now you know what to expect from the signup offer at Underdog, you're probably keen to get started, but I recommend brushing up on the T&Cs and eligibility criteria first, as these can change with time. This isn't unique to Underdog - my ParlayPlay review also shares a similar outlook, making for an excellent alternative that's also worth a closer look.

Here's a step-by-step guide to signing up and claiming your Underdog bonus:

  1. Follow the link in our banners: Click or tap on one of our banners on this page to go straight to the site, making a note of any current promo codes, if available. Then hit the Sign Up button to open the registration box.
  2. Fill out the registration form: Input a few details, including your username, email address and date of birth, then create a password. This is where you'll need to input your promo code, if you picked one up from our banner. Note that Underdog uses geolocation software to confirm that you're in an eligible state, and that you'll need to complete ID checks too, including the last 4 digits of your SSN.
  3. Deposit at least $10 and enter a $5 contest: The preliminary steps cleared, you'll need to deposit at least $10 into your account, using options that include PayPal, debit cards, and bank transfer. Now you need to play $5 in any pick'ems or daily drafts., to activate the release of $75 in bonus funds into your Underdog account. It's worth noting that it can sometimes take up to 72 hours for the bonus to be awarded.
  4. Play smart with your $75 bonus and cash out wins: Bonus funds at hand, your options include Best Ball Contests, Pick'em Contests, Battle Royale & Daily Drafts, and Champions. Even better, you only need to playthrough your bonus 1x for any winnings to become withdrawable. Be aware that the bonus funds themselves are never available for withdrawal - only winnings arising from them can be cashed out

5 go-to tips for maximizing the Underdog bonus

Bonus claimed and ready to jump into the fray? Hold up, as there are some tips I need to pass on, otherwise you could end up losing your bonus funds quicker than you got them. Speaking from personal experience, I found more value in focusing on leagues I was already familiar with, scaling in with low-entry contests, but there's still more to consider, as I share below. These tips are not limited to Underdog - they could equally apply to the DraftKings promo code too, which I highly recommend exploring to broaden the net.

🎮 Tip 1: Keep your play to familiar sports at first

Let's start strong - your plays are only as good as your understanding of the sports and the squad on field. So for your initial bonus at Underdog, you should target your favorite sports, which could be NFL, NBA, or MLB pick'em contests. And this is where prior knowledge shines, as you'll already be aware of the likely players to perform well. Underdog has built-in tools that enable you to track elements such as player performance and injury updates, enabling you to convert seemingly "on the whim" bets to informed plays. I further layered this with low-entry contests, gradually scaling up as I grew my playing balance. For expert analysis to inform your picks, explore our predictions for NFL, NBA, and MLB.

📅 Tip 2: Flag action-packed game days on your calendar

Many typical DFS bonus tips suggest avoiding high-volume game days, and the advice certainly isn't unfounded, especially if you are working with a low bonus amount. But, here we're flipping the script, while prepping for this well in advance to avoid last-minute rushes. So why should high-volume game days be of interest? For one, I've found that it's when participation in these contests peaks, so you're not competing in "skewed" contests - and more players evens out the playing field. As a bonus, expanded prize pools lock in (going as high as $1M+), not forgetting multipliers on selected projections, which is something of a specialty at Underdog.

To avoid the usual pitfalls, I marked events/games/players and potential contests that I'd like to get involved in well in advance. I also had all the key players' data at my fingertips, from injuries to player form, and this worked well. It meant that even on late scratches, I could easily factor them into my prediction, without casting around to find balance. It's a case of opportunity meets preparedness, as the saying goes!

🤝 Tip 3: Help yourself to additional bonuses by referring friends

Underdog places limits to the welcome offer being used in conjunction with other promos. But here's the workaround: the refer-a-friend bonus is more of a passive promo than an active one, and you're likely to turn to it once the signup offer is exhausted, so you'll be staying well within the requirements. It's my belief that DFS is even more enjoyable with friends, and it's even better that this comes with extra perks. Simply copy and share your referral link with friends (they must use it to sign up for the promo to apply), and when they make an initial deposit of $10 or more, you'll receive more bonus funds.

💡 Tip 4: Explore a variety of different contests with your bonus

I also suggest trying out the different contests on Underdog, while sticking with familiar sports to avoid "longshot" entries. Thankfully, either of the Underdog sign up offers gives you more than enough to explore the options. It can be on Best Ball drafts for hands-off, season-long play with your lineup auto-optimizing weekly, or Daily Drafts, with six-player squads (one QB, one RB, two WRs, one TE, one flex) against the clock. Pick'em games are also worth further exploration too (with quick higher / lower picks on player stats), as are Battle Royales with the last team cashing out big. My strategy here was to spread the bonus across the different contest types to diversify risk. Better yet, Underdog has filters for narrowing down your ideal contest by entry fees, projected payouts, etc., that you can easily use to identify slates that are to your liking.
