What you get with the Underdog Fantasy welcome offer

Underdog Fantasy doesn’t give new players the run-around when claiming the ‘Play $5, Get $100 in 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 $100 bonus entries when you make a deposit and place a $5 wager.

The Underdog Fantasy bonus doesn’t credit your account right away. After making your first bet, 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.

As reiterated in my Underdog Fantasy review, players in most areas must wager their deposit and bonus once before they can withdraw winnings. I’m not complaining because those are pretty low wagering conditions that’ll see you turning a cash payout a lot quicker.

How to get your Underdog Fantasy promo

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

  1. Click on any of the links for Underdog Fantasy 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 bet
  6. Start betting with your promo credit

How I used these bonus offers at Underdog Fantasy

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 Fantasy bonus code. But I quickly reached out to the customer service team and they applied it on my behalf. Underdog Fantasy 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 under 48 hours. I could use the bonus on any daily fantasy sports on the site, so I went with the NFL. Remember, I had 60 days to use the bonus, so I took my time to build my dream team. 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 wagering conditions

For players in most places, there’s only a 1x playthrough condition standing between the bonus and withdrawing your winnings. These are reasonable wagering terms and among the lowest I’ve seen. I also like that I had 60 days to meet these, which is realistic. 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 Fantasy 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 are free? 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 Fantasy 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 Fantasy 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 Fantasy deposit bonus credits your account, it won’t be lying around indefinitely. The clock starts ticking, and you likely have 60 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 wagering 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 Fantasy welcome offers.

⚽ Contest type matters

I reckon you’ll have a better chance of enjoying a return from the Underdog Fantasy 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 bonus cash 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 Fantasy is whipping up a rewards program soon. In the meantime, you can also take advantage of the ongoing Underdog Fantasy promotions like the Multiplier Boosts. The site offers enhanced odds 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 Fantasy 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 wagering 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 Fantasy promo code FAQ

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

Yes, you do. Underdog Fantasy 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 Fantasy offer?

The Underdog Fantasy 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 gambling 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 Fantasy bonus for global players expires in 60 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.
