FanDuel Promo Code Overview for March Madness Round of 64

Activating the FanDuel promo code for Thursday’s March Madness slate is quick and easy. New users can take advantage of a daily No Sweat Bet up to $300 for 10 consecutive days, offering up to $3,000 in total bonus bet value throughout the promotion.

According to sportsbook analyst Chris Ilenstine, this welcome offer stands out for the Round of 64 because it provides consistent daily value, giving bettors multiple chances to capitalize across the tournament’s biggest matchups.

“If you’re betting on the Round of 64 and not using the FanDuel welcome offer, you’re leaving value on the table. Ten straight days of No Sweat Bets up to $300 gives you consistent opportunities to attack different matchups across the slate, especially during a high-volume stretch like March Madness. It’s one of the best ways to stay active and maximize returns throughout the tournament.” — Chris Ilenstine, Sportsbook Expert

The structure of the FanDuel promo offer gives bettors built-in protection on major college basketball markets. If your daily wager loses, FanDuel refunds the stake as bonus bets up to $300, allowing you to stay active across the slate. With several high-profile games today, bettors can explore markets across the league as March Madness intensifies, including these games. Check out my example for how to bet on the college basketball slate below.

March Madness Prediction for Siena vs. Duke

For tonight, my March Madness prediction comes from the Siena vs. Duke game. Suppose you place a $300 bet on Duke -28.5 (-110). There is no doubt Duke -28.5 is a strong play due to the major gap in talent, size, and depth. The Blue Devils should dominate the glass due to the presence of Cam Boozer, force turnovers, and generate easy points in transition. With Duke’s ability to go on scoring runs and maintain intensity for 40 minutes, this game can get out of hand quickly, making the spread very attainable.

• Siena vs. Duke Prediction: Duke -28.5 (-110)

Two possible outcomes apply:

• If the bet wins: You receive a $572.73 total payout, and the wager settles as normal with no bonus bets awarded
• If the bet doesn’t win: FanDuel returns your $300 stake as bonus bets, which must be used within seven days

Bettors can also use tools like a parlay calculator to estimate potential returns when combining college basketball odds or other markets on the day’s schedule.
