Underdog Fantasy sign-up offer at a glance
Underdog — now rebranded Underdog Sports — reinvented season-long fantasy with snake-draft Best Ball and the smoothest Pick'em product on the market. Its verified new-user offer: play $5, get $50 in bonus entries with official code UDPROMO.
The headline is a verified 'Play $5, Get $50 in Bonus Entries' offer: enter $5 in real-money contests and Underdog credits you $50 in bonus entries, using official code UDPROMO. This replaced the older 100% deposit-match structure. Bonus entries are contest credits rather than withdrawable cash — winnings from them pay out normally, but the entries themselves cannot be cashed out. Industry trackers report a 14-day expiry on the entries and say they can be used across the app, including Pick'em and Underdog Predict. Best suited to: Best Ball drafters and Pick'em players who want a modern interface.
How to claim the Underdog Fantasy code, step by step
- Open the Underdog offer. Tap the sticky claim button or the link above to open Underdog through our tracked link. Note the site is now underdogsports.com — the old underdogfantasy.com address redirects there.
- Create your account. Sign up with your email or phone, then verify your identity and location. Underdog is 18+ in most states (19+ in NE/AL, 21+ in AZ/MA/IA), and trackers report the new-user offer is not valid in MD, MI, NJ, NY, OH or PA.
- Enter code UDPROMO. In the 'Promo code' field during sign-up or deposit, enter UDPROMO — the official code advertised on Underdog's own homepage (verified August 8, 2026). If an exclusive code is shown at the top of this page, that code works the same way.
- Deposit and play $5. Make a deposit and enter $5 in real-money contests — Best Ball drafts or Pick'em selections both count toward the qualifying play.
- Use your $50 in bonus entries. The $50 in bonus entries lands after your qualifying play. Use the entries before they expire — industry trackers report a 14-day window — and any winnings from them pay as withdrawable funds.

Wagering & rollover requirements, in plain English
Treat the 1x figure above as nominal — this is not a deposit match with a wagering requirement. Your $5 in paid entries unlocks $50 in bonus entries, and you 'clear' them simply by using them on contests before they expire (14 days, per industry trackers — confirm in-app). Anything those entries win pays as withdrawable funds. That makes the real discipline timing rather than volume: claim the offer in a week you actually plan to play. For NFL players, that means signing up against the Week 1 slate.
