Enjoy $50 bonus entries when you join Underdog

When I signed up at Underdog for the first time, I discovered a generous 'Play $5, Get $50 in Bonus Entries' offer for new users, which I easily claimed by entering a promo code (this only applies in certain states).

The Underdog welcome bonus offers new users a first deposit match of 50% their initial deposit in bonus entries - up to $1000. This is subject to a 1x play requirement before withdrawal. Besides the welcome bonus, I also came across a referral program that paid us $10 in bonus entries for every new user I invited to the platform.

Sign up and enter the Underdog promo code to unlock the bonus

Here’s a step-by-step guide on how I got my hands on the welcome bonus:

  1. Click one of the banners on this page to visit the Underdog app or site.

  2. Click the ‘sign up’ button.

  3. Enter your email, password, preferred username, and date of birth in the provided fields.

  4. Input the promo code for the welcome offer and confirm by clicking the ‘Sign Up’ button to complete your registration.

  5. Head to the Cashier section and make a deposit and play $5 to receive $50 in bonus entries.

  6. Play through the bonus once to make it available for withdrawal.

Underdog’s welcome bonus only has a 1x play through requirement, which is pretty standard in daily fantasy sports platforms. The match deposit bonus also comes with a 60-day validity period.

Top 5 expert tips to maximize your Underdog promo

Although the $50 in bonus entries is a generous offer, it won’t seem like a lot if you’re not managing it properly. Here are my tested tips to supercharge your Underdog bonus as a beginner to daily fantasy sports:

Start with your favorite leagues

Underdog features the top five sports leagues: MLB, NHL, PGA, NBA, and NFL, so there are many options for players. Since we’re relatively up to date on the latest NBA and MLB news, I stuck to those options when playing at Underdog.

Receiving good at daily fantasy sports is difficult enough. You don’t want to throw in the pressure of learning a new sport.

Utilize other Underdog promos

Besides the welcome bonus, I came across other promotions that helped supercharge my experience. For instance, you can use Pick’em Boost multipliers and Pick’em Specials to receive extra Bonus Entries to spend on games.

You can also use the Playback Program to receive rewards on your Pick’em entry fees as Bonus Entries during certain promotions. While I didn’t play enough to witness any Playback events, the point of the story is to always keep an eye out for promotions that keep up the fun.

Conduct in-depth research

Although daily fantasy sports is not the same as sports betting, I recommend approaching it in a similar way. You can do good at DFS with in-depth research and strategic thinking. Before putting your team together for your next game, it’s best to conduct some real research into each of your players to see how well they fit into your team.

Stick to low buy-ins for a start

One thing I’ve noticed on the best daily fantasy apps is how inexperienced players tend to enter games with high buy-ins. You’re statistically better off sticking to lower buy-ins when you’re just starting out, as it reduces your chances of being paired with far more experienced opponents

Five fast facts about the welcome bonus

What deposit options are available at Underdog?

You can fund your account using Trustly, PayPal, Visa, Mastercard, Apple Pay and Venmo. The available deposit options may vary based on your location, but popular payment optopns seem to be available to all users.

Is there a promo code?

Yes, certain states require a promo code and I had to enter a promo code to unlock the match deposit welcome bonus for new users. While the code may be subject to change, the DFS site always provides the current code.

In my case, the code was featured on the website’s homepage. If you’re having issues locating the current promo codes on your own, you can also contact support.

When does the bonus offer expire?

The bonus has a 60-day validity period. You’ll have to forfeit all bonus funds if you fail to complete the playthrough requirement after 60 days of claiming them. Thankfully, Underdog allowed us to join contests with my bonus funds before playing with the deposited cash, so the bonus is unlikely to expire.

What happens if you forget to input your promo code?

Underdog is lenient with its promo code, as the platform allows you to redeem your bonus even if you forget to enter the code. In my case, I simply reached out to the site’s support channel, and a customer service agent retroactively applied the code to my account.

What happens if you don’t complete the playthrough requirement within the time limit?

If you don’t complete the playthrough requirement in 60 days after receiving the welcome bonus, you’ll have to forfeit the reward. While the winnings from the bonus entries will be left untouched, Underdog takes away any leftover bonus entries.

No VIP program at Underdog

Throughout my Underdog review, I didn’t come across any VIP or loyalty program on the platform. The only initiative that comes close to a rewards program is the Refer-a-Friend program, an arrangement where the site rewards existing players for inviting new users.

When you opt into the Refer-a-Friend Program, you’ll receive a unique referral code you can share to friends interested in signing up at Underdog. Once someone registers with your referral code, you’ll receive a $10 bonus.

Introduction to Bonus Offer

Underdog started us off with a welcome bonus on my first deposit. Claiming the bonus was easy. I only had to create an account, apply the promo code, and make my initial deposit to receive the bonus entry.

I was able to spend the bonus on all Underdog games, and the 1x play requirement was easy to meet. I recommend keeping the validity period in mind when using this bonus, as it’ll simply disappear if unused within 60 days.

Reality Test

Claiming the bonus was easy. I initially forgot to enter the code, but I quickly contacted customer service, and they applied the code on my behalf. After getting the bonus entry, I spent it on a few NBA and MLB picks, just like regular entry.

While I lost most of the matchups I spent the bonus entry on, I won a few. Thanks to the 1x playthrough requirement, the winnings were credited to my withdrawable balance. Compared to other DFS sites, Underdog’s welcome bonus is easy to claim, use, and potentially withdraw.

Bonus Withdrawal

If you’re already experienced with daily fantasy sports, blazing through the beginner-level games shouldn’t be a problem. Since the 1x playthrough requirement is the only obstacle between the bonus entry and withdrawal, you won’t have issues playing through and withdrawing the welcome bonus.

Pitfalls & What to Avoid

After some digging, I discovered that the Underdog welcome bonus has a 60-day validity period. It’s best to play through the bonus before the time is up. 60 days is a long time, so I don’t expect you to encounter any problems with this timeline.

Note that the bonus entry isn’t withdrawable. You must play through it at least once, which is standard practice in most DFS sites. I even expected a higher playthrough requirement, but we’re certainly not complaining.

Kickstart your DFS experience with this unbeatable bonus

Underdog’s welcome bonus is an excellent one for first-time daily fantasy sports players, as it starts you off with bonus entry to join contests and explore the platform. Claiming the bonus is easy; simply head over to the platform, sign up, and enter the promo code from their website.

The welcome bonus isn’t the only way to obtain bonus entry. I also discovered the Refer-a-Friend program, a referral arrangement where you receive $10 for each new user who signs up using your sports promo code.
