Underdog Promo Code: Get $75 in Bonus Entries - February 2026

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.

How to Claim the Underdog Promo Code

Here’s how I opened an account and claimed the welcome bonus using the WSN Underdog promo code:

1. Download the Underdog app (iOS/Android) or visit the site via one of the links on this page.

2. Click ‘Sign Up’. 

3. Create a username and password, then enter your email address and date of birth. Type the code ‘WSNPLAY’ into the promo code field (if you don’t do this, you won’t trigger the bonus).

4. When you proceed to the cashier, you’ll see a pop-up with the bonus. Click ‘Deposit now’ and fund your account with $10 or more.

5. Return to the homepage and play $5 or more in Fantasy Entries.

Key Terms and Conditions

Bonus entries don’t hold any cash value. You’ll have to play through the full amount before you can withdraw any winnings. Here are the main things you need to know before claiming the Underdog Fantasy bonus code offer:

• Playthrough: 1x Bonus Entries.

• Expiration: 14 days.

• Eligibility: 18+ in most states, check local rules before claiming.

• Location: Not available in all Underdog states, check the promotions page before signing up.

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:

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.
