How the Fanatics Sportsbook promo code works for Thursday's game

The Fanatics Sportsbook promo code SIBONUS350 delivers $350 in guaranteed FanCash when you bet $20 or more on any sports market with minimum odds of -500. This offer is structured to reward you daily over a week, giving you $50 in FanCash each day for seven consecutive days. Whether you're backing Dallas' high-powered offense led by Dak Prescott and CeeDee Lamb or betting on Tampa Bay's defense to contain the attack, you'll have bonus funds to work with throughout the week.

Here's what you need to know about this Fanatics Sportsbook new-user promo: You must deposit a minimum of $10 to activate the bonus, and your initial qualifying bet must be $20 or more at odds of -500 or longer. If you place a $20 bet on Dallas to win Thursday's game at -110 odds and the Cowboys pull out a victory, you'll earn your first $50 in FanCash immediately. If your bet doesn't hit, you'll still receive your first $50 in FanCash the next day, allowing you to continue betting on upcoming games.
