Underdog promo code terms & conditions

The Underdog promo code SBRBONUS delivers exceptional value for fantasy sports enthusiasts looking to capitalize on the 76ers vs Celtics series opener. This welcome bonus provides $50 in fantasy entries after your initial $5 play, creating multiple opportunities to build winning lineups around key players like Tyrese Maxey and Jayson Tatum. The bonus comes with a reasonable 1x wagering requirement that must be completed within 14 days of receipt.

Key terms and conditions include:

  • Must use promo code SBRBONUS to qualify
  • Available to users 18+ in eligible states (excludes NJ, NY, MD, OH, MI, PA)
  • Bonus entries expire after 60 days if unused
  • Account verification required before withdrawals

For example, if you create a Pick'em entry predicting Maxey will exceed his scoring projection in Game 1 and win, your $5 entry could return significant winnings while your bonus entries provide additional chances to profit. Even if your initial play doesn't hit, the $50 in bonus entries gives you ten more opportunities to find winning combinations throughout the playoffs. The timing couldn't be better with Embiid's absence creating value opportunities on Philadelphia role players who may exceed expectations against Boston's elite defense.
