How the FanDuel promo code new-user offer works for March Madness betting
This FanDuel sign-up bonus provides exceptional value for new customers looking to bet on March Madness. No FanDuel promo code is required to claim this welcome offer. After creating your account and making a minimum $5 deposit, you'll receive one No Sweat Token daily for 10 consecutive days.
Each No Sweat Token can be applied to any wager, including bets on Tuesday's First Four matchups between UMBC and Howard or Texas and NC State. The key terms include:
- Maximum refund of $300 per No Sweat Token.
- Refunds credited within 72 hours of bet settlement.
- Refunds issued as non-withdrawable bonus bets expiring in 7 days.
- No Sweat Tokens expire 24 hours after receipt.
For example, if you place a $200 bet on UMBC to upset Howard and the Retrievers lose, you'll receive $200 in bonus bets. If Texas covers the spread against NC State and wins, you keep your original stake plus winnings. This structure allows you to explore different betting markets across both First Four games while having protection on losing wagers.

Ryan Hagen’s foray into sports betting started early. At just 14 years old, he sought out a lottery kiosk clerk with relaxed gambling mores and convinced the fella to sell him ‘Sport Select’ tickets, which were part of the original government sports betting program in his native Alberta. Now a betting analyst at Sports Illustrated, Ryan prefers to place his bets legally and has established himself as an authority in the sports betting industry. His roles have included lead writer, content editor, managing editor, and more. Ryan has written and edited hundreds of sportsbook reviews and countless news, analysis, and promotional pieces for some of the most prominent companies in the sports betting world. As someone who eats, sleeps, and breathes sports and sports betting, Ryan’s goal is to impart his unbiased betting knowledge to prospective bettors, allowing them to make informed decisions, whether that’s signing up for a sportsbook, mulling over a moneyline, or placing a prop bet. A prolific bettor himself, Ryan lives for the NFL season and believes that every Saturday night from September to February is akin to Christmas Eve. Ryan has a B.A. in Communications from Royal Roads University in Victoria, British Columbia. His work is widely published in the sports betting industry and in publications such as the Calgary Herald and Vancouver Magazine. Off the clock, he can be found traveling, searching for noodles, working on his golf swing, and managing his degenerate number of fantasy football teams.
