With the FanDuel promo code today, September 18, 2025, win your $5 first bet on Dolphins vs. Bills TNF or NFL Week 3 and get $300 in bonus bets. New users can access the FanDuel promo code right now and place a first bet on any market or odds, including this Thursday NFL matchup to claim the welcome offer.
The Bills currently have the second-best odds to win the Super Bowl on FanDuel Sportsbook, at +550. They look to continue the early season success and start 3-0. With a loaded roster and home field advantage, they are currently 11.5-point favorites against the Dolphins on Thursday Night Football.
Meanwhile, the Dolphins have all the pieces of a good team but are off to an 0-2 start. If things don’t turn around quickly, the Dolphins could very well be one of the worst teams in the NFL this season and look to rebuild with a new quarterback or a new wide receiver group.
Use this lopsided Thursday Night Football game to your advantage with the FanDuel promo code offer. This matchup provides a good chance to win your $5 first bet and therefore claim the $300 in bonus bets.
