The "Refer-a-Friend" promotion allows Underdog Fantasy users to earn bonus funds by referring new users.
The "Refer-a-Friend" promotion, as advertised in-app and on-platform, allows current Underdog users ("referrers") to refer new users ("friends") to make their first deposit on the Underdog platform. When a friend enters the referrer's Underdog username as the referral code during account creation and successfully deposits at least $10, the referrer will receive a credit (the "Program Credit") in the amount clearly stated in the promotion advertisement. To qualify, you must have deposited, and your friend must sign up via your link and make their first entry. To apply the referral code correctly:
Using the Referral Link: Your friend can download the Underdog app and click on your referral link. The code should automatically populate in the "Promo Code (optional)" section.
Manual Entry: If the code does not populate automatically, your friend must select "Add Promo Code" and manually input your referral code.
The Refer-a-Friend bonus is awarded as bonus cash plus a Rips card pack. The referrer cannot withdraw the awarded bonus cash. The "Refer-a-Friend" promotion allows Underdog users to earn bonus funds by referring new users. To earn the bonus funds, new customers must complete a qualifying deposit and play a qualifying amount in entries. The exact amounts can vary and are shown in the Refer-a-Friend section of the app. Draft entries don't count toward this requirement, and opening a Rips pack is not a qualifying entry on its own — it's a separate welcome reward the referee receives automatically for signing up with the code. The referee (the friend who was referred) also receives their new user welcome offer plus a Rips pack. Some common issues affecting referral bonuses:
Incorrect code application: If the referral code wasn't applied during sign-up, the bonus will not be processed.
Different promo codes: If your friend used another promo code, your referral bonus becomes invalid.
To find your referral link, click on the "account" tab in the top right corner. From there, scroll down until you find the "invite friends" tab. From there, you may share or copy your link and send it to your friend that you'd like to refer. Further guidance on locating this can be found below.
Redemption of the Promotion is expressly conditioned upon acceptance of and compliance with all of these Terms & Conditions.

What is the Refer-a-Friend Jackpot?
We've added a limited-time jackpot on top of our existing Refer-a-Friend (RAF) program. Every time you make a successful referral, you're automatically entered for a chance to win a jackpot bonus in bonus cash — no extra steps required.
How does it work?
The Refer-a-Friend program works the same way it always has, with one exciting addition: approximately 1 in every 1,000 referrals is randomly selected to win the jackpot.
Most referrals (999 out of 1,000): You receive your standard refer-a-friend reward just like before.
Jackpot referral (~1 in 1,000): That referral pays out a jackpot bonus, delivered as bonus cash.
Every successful referral is evaluated independently and at random, so each one is a fresh shot at the jackpot.
How do I win the jackpot?
You don't need to do anything differently. Just refer a friend the way you normally would. If your referral qualifies and it happens to be the lucky 1-in-1,000, you win the jackpot.
There's no code to enter, no form to fill out, and no way to influence which referral hits — it's completely random.
Where is my jackpot reward?
If you won the jackpot, your reward is delivered as a jackpot bonus in bonus cash. Keep an eye on your account; the bonus cash will be credited following your qualifying referral.
If your referral qualified but you received your standard reward (e.g., $50 or $40), your referral was not the jackpot winner. The jackpot hits approximately 1 in every 1,000 referrals, so most referrals will pay out the standard amount.
Does my referral still need to qualify the normal way?
Yes. A referral must meet all the same requirements as a standard referral to be eligible — both for the base reward and the jackpot. If a referral doesn't qualify, it is not eligible for either.
What are the odds?
The jackpot hits on approximately 1 in every 1,000 referrals, at random. Each referral is an independent chance — past referrals don't affect future ones.
Full odds and terms are available on the Refer-a-Friend page in the app.
