The Underdog Fantasy promo code unlocks a generous welcome offer that provides new users with $75 in bonus credits after making an initial $5 entry into any contest. This promotion is perfect for Monday night's Dolphins vs. Steelers game, where you can build fantasy lineups featuring players like De'Von Achane, who has rushed for over 1,100 yards this season, or make pick'em predictions on whether Tua Tagovailoa can overcome his struggles in cold weather games. The bonus carries a 1x wagering requirement and must be used within 60 days of receipt. The initial qualification period expires within 72 hours of your first deposit.

Key terms include age restrictions of 19 years or older (21+ in Virginia), account verification requirements before withdrawals, and geographical limitations excluding Maryland, Michigan, Pennsylvania and Ohio.
