FanDuel Promo Code Details for Spurs vs Mavericks
FanDuel's new user welcome bonus requires no FanDuel promo code and offers a straightforward path to bonus betting funds. New users must download the FanDuel Sportsbook app, make a minimum $5 deposit, and place their first $5 real money wager on any available market, including the Spurs vs Mavericks season opener. If your initial bet wins, FanDuel awards $300 in bonus bets within 72 hours of settlement.
