What is the Underdog Promo Code Offer?

This offer is a super straightforward, low-stakes option for players looking to explore daily fantasy sports. It’s a great alternative to the non-exclusive Underdog sign up offer (50% deposit match up to $1,000), which requires a greater financial commitment to extract similar value.

  • Playthrough: 1x Bonus Entries.

Underdog Promo Code vs. Competitors

Most competitors offer deposit match welcome bonuses, which offer more to high rollers than casual players. The fixed-value offer available via the Underdog promo code is better for a new user who wants to get as much value as they can from a $10 deposit.

What Our Experts Think of Underdog

I asked our team of experts what they think of Underdog. Here’s what three of them had to say:

  • “Underdog manages to convey a huge amount of information through its incredibly clean, user-friendly interface. You can easily view the sports news feed, player statistics, and details of past performances while making your picks. It’s the complete package for serious drafters.”
  • “The ‘Rescues’ feature has saved countless parlays. If one of your picks plays in the first half of the game and doesn’t return in the second half, you might be eligible for a refund. This applies regardless of why they were sent off, whether that’s injury, rest, or rejection; just choose the ‘Higher’ option when making the selection for that extra peace of mind. On top of your refund, you’ll receive an extra Gimme Pick the next day.”
  • “Depositing and withdrawing at Underdog couldn’t be more straightforward. Instead of enforcing a fixed minimum withdrawal amount, you’re allowed to request less than $10 if you’re clearing the last few dollars from your account. It’s a small detail that puts the customer first.”

Real User Reviews: The Good and the Bad

Underdog boasts a 4.8-star rating on the App Store and 4.6 on the Google Play Store, and has received over 300k ratings across both platforms.

Reviews highlight many qualities players like about the app, including its excellent user interface, daily promo offers, and higher multipliers on 3-pick parlays than competitor platforms.

Some reviews suggest support is not always able to solve issues in an effective and timely manner. Others would like to see Underdog facilitate instant withdrawals, since a handful of competitors offer this service.

Strategy: The Power of Correlation in Pick'em

Underdog allows you to pair players from the same team to increase your edge in a technique known as stacking. The occurrence of certain events makes others more likely, so stacking can help you create smart, cohesive entries.

Let’s say you bet ‘Higher’ on a QB’s passing yards. If this hits, it’s likely that his WR’s receiving yards will hit too, making it a good idea to add this to your lineup.

Underdog adjusts payouts if they detect correlation in your entry. Learning how to identify ‘weak correlations’ is the key to a strong long-term strategy.

Making Your First Deposit with Underdog Promo Code

To unlock your welcome bonus, you will need to make a minimum first deposit of $10. Even if you only plan to enter a smaller draft, that $10 threshold is strictly required to successfully trigger the promo code offer.

When it comes to actually funding your account, it is best to stick to the most reliable payment options. I highly recommend using PayPal or Online Banking (via Trustly). These are the absolute best methods available because they allow for completely seamless transactions for both your initial deposit and your future withdrawals.

Important Bonus Rule: Before you finalize your payment, keep these two rules in mind to avoid future headaches:

  1. Credit Cards: While you can easily use a credit card to fund your account, you usually cannot withdraw your winnings back to one. You will need to link a standard debit card or bank account when it is time to cash out.

  2. Prepaid Cards: Avoid using prepaid cards, such as Cash App cards, for your first deposit. Underdog typically requires you to withdraw using the exact same method you used to deposit, and prepaid cards frequently cause frustrating payout delays. Stick to standard banking for your first transaction to keep things simple.
