What you get with the Underdog welcome offer

Underdog doesn’t give new players the run-around when claiming the ‘Play $5, Get $75 in  Fantasy Bonus Entries‘ offer. A simple registration process that takes only a few minutes is needed, and then you can follow the steps to get this offer. But I can’t stress the importance of entering the promo code to activate this offer. Also, you only receive the $75 fantasy bonus entries when you make a deposit and place a $5 entry.

The Underdog bonus doesn’t credit your account right away. After making your first entry, give the operator up to 72 hours to release the offer. Remember to only use approved deposit methods to fund your account. Currently, the site mostly favors card holders, so you can deposit using Visa, Mastercard, Amex, and Discover. Alternatively, you can use PayPal, but that’s about it.

To be eligible for this offer you must be 18 or above, or 19 or older in AL and NE, 19 or older in CO for specific contest types, and 21 or older in AZ, MA, and VA, and must be physically located in a state where Underdog operates. This offer is void in  MD, MI, NJ, NY, OH, or PA. Terms and Conditions Apply.

As reiterated in my Underdog review, players in most areas must play their deposit and bonus once before they can withdraw winnings. I’m not complaining because those are pretty low entry conditions.

Remember to play responsibly. Gaming problems? call 1-800-GAMBLER or visit ncpgambling.org. For New York: You can reach the 24/7 HOPEline at 1-877-8-HOPENY or text HOPENY (467369).

How to get your Underdog promo

I loved just how easy it was to get the Underdog promo offer. Here’s a quick recap of how you can claim this deal:

  1. Click on any of the links for Underdog in the banners of this page
  2. Create your first-ever account by filling in the registration form with your personal information
  3. Enter in the required promo code
  4. Make an opening deposit with one of the payment methods
  5. Place a qualifying entry
  6. Start playing with your promo credit

How I used these bonus offers at Underdog

I found the bonus entries simple to claim. I just had to go through the four-step registration process, making sure to enter the correct details. Initially, I had overlooked the Underdog bonus code. But I quickly reached out to the customer service team and they applied it on my behalf. Underdog does ask for at least 72 hours’ leeway to credit your bonus after your first deposit. Well, the site exceeded my expectations because I received mine in just 48 hours. I could use the bonus on any daily fantasy sports on the site, so I went with the NFL. Since I could enter any paid contest I wanted, I went with Best Ball games that needed a $25 entry fee. I didn’t win all the contests, but I was fortunate with a few.

Understanding those entry conditions

For players in most places, there’s only a 1x playthrough condition standing between the bonus and withdrawing your winnings. These are reasonable entry terms and among the lowest I’ve seen. Seeing as it wasn’t impossible to satisfy these, I was able to request a withdrawal. I used Visa to withdraw, even though you can also opt for a bank transfer. 48 hours seems to be the magic number at Underdog because I received my rewards within that time. However, bank transfers will take much longer than that. Expect to wait up to 5 days. Did I mention that withdrawals on the site do not come with a fee? You receive whatever amount you request as it is. Ultimately, I don’t think you’ll face any issues withdrawing your bonus funds here.[/toggle-item]

Checking out the small print of this Underdog promo

I wouldn’t say there’s a list of pitfalls to heed when claiming the Underdog bonus because it’s pretty cut and dried. I will mention that account verification is a must before you can withdraw winnings. In fact, I believe it influences the turnaround time for your first withdrawal. Make sure you submit the correct and clear documentation for account verification well in advance. Also, don’t attempt to withdraw winnings before playing them through once. It’s not an unreasonable task, so I’m pretty sure most people can achieve it.

Five tips – Make the bonus work for you

I maintain that as modest as the Underdog bonus is, it can offer players real value. You just need to know how to work it. I’ve included a few tips to help you make the most of it.

💰 Deposit within your means

Let’s face it: DFS can be risky. So always stay within your means and never deposit more than you can reasonably afford to lose.

⏳ Watch the expiry date

Once your Underdog deposit bonus credits your account, it won’t be lying around indefinitely. The clock starts ticking, and you likely have 14 days to use it before it expires. Firstly, I commend the site for giving you ample time to work on the bonus. Secondly, I get that a 1x playthrough condition isn’t that difficult to track, given the expiry dates to date. However, you still need to keep an eye on the calendar.

🏆 Concentrate on high-entry contests

You might prefer to enter contests with the lowest fees to spread your bonus. After all, this should help you make the most out of the Underdog welcome offers.

⚽ Contest type matters

I reckon you’ll have a better chance of enjoying a return from the Underdog bonus if you stick to what you know. Participate in familiar fantasy sports and join contests you understand fully. If you know football in and out, from the best players and teams, go with that. This is a good place to research more about the contest you are interested in, including rules, past stats, and the works.

🥚 Don’t put all your eggs in one basket

Piggybacking on the previous point, I’d tell you to enter as many contests as possible. Diversifying your lineup is a strategy that yields results as opposed to using all your fantasy bonus entries on one contest. When you split your bonus across different rosters, you balance your winning chances.

Rewards & Loyalty – Refer friends and receive bonus credit

I didn’t find a rewards program on the site, which is a shame, considering it’s not really among the new daily fantasy sites and therefore will need to cling on to its existing customers. The closest initiative to a loyalty program on the site would probably be the referral scheme. When you invite a friend to sign up with Underdog and deposit, you receive a bonus. I suppose you enjoy the benefits of this reward more if you have a chain of gaming buddies on speed dial.

Hopefully, Underdog is whipping up a rewards program soon. In the meantime, you can also take advantage of the ongoing Underdog promotions like the Multiplier Boosts. The site offers enhanced awards for Pick’em competitions to increase those payouts. There may not be a lot of these promos currently, but the available deals still go a long way in enhancing play.

Conclusion – A great bonus for new DFS players

After testing the Underdog deposit offer, I have no doubt it’s a reasonable deal. When used optimally, it brings real value. After all, you don’t come across a 1x playthrough condition and 60-day expiry date duo often. Yes, I would have loved it if the site bumped up the bonus a little, but you still get an instant boost. If you’ve never tried out a DFS site, I believe this offer will ease you into things, minus the pressure. Besides, you can play any sport and join any contest you want. What’s not to like?

Underdog promo code FAQ

🏅 Do I need a promo code to claim the bonus?

Yes, you do. Underdog explicitly displays a promo code on its official website. You must enter it in the designated field during registration to successfully activate the offer.  

👀 Who can claim the Underdog offer?

The Underdog sign-up offers are for new DFS players who’ve never opened accounts with the site before. Inactive accounts that have now been reactivated don’t qualify. In addition, you must be accessing the site from an authorized location. Lastly, only players aged 18 years old and above can claim the bonus.

⭐ Can I claim the bonus more than once?

Players can only claim the Underdog bonus once. That’s pretty standard for any bonus, actually. I might as well point out that this means one bonus per household and IP address. Attempting to claim the bonus more than once is considered bonus abuse and has undesirable consequences.

🏒 Which sports and contests can I use the bonus on?

As it stands, you can use your bonus play major markets like the NFL, NHL, MLB, and NBA. The site also covers niche sports like golf and NASCAR. As for contest types, you can take your pick from Best Ball games, Battle Royale, Pick’em contests, and more.  

❓ What can I do if my bonus expires?

The Underdog bonus for global players expires in 14 days, no matter where you claim it from. That’s a lot of time to play your bonus, considering the playthrough conditions are only set at 1x.
