New customers only. Offer availability varies by state. Terms, including FanCash terms apply-see Fanatics Sportsbook app.

Friday, Oct. 23 brings a loaded sports slate, and there's no better time to join Fanatics than now. New users can claim $350 in FanCash with the Fanatics Sportsbook promo code SIBONUS350. Whether you're eyeing the World Series Game 1 matchup between Tampa Bay and Milwaukee at 8:00 PM ET, the Knicks-Celtics showdown, or Duke-Virginia college football action, this welcome offer gives you plenty of bonus funds to explore the platform.

How the Fanatics Sportsbook promo code works for Friday's games

The Fanatics Sportsbook promo delivers $350 in guaranteed FanCash when you meet the requirements. Here's what you need to know about claiming this bonus for Friday's action:

Register with promo code SIBONUS350 during sign-up.
Make a minimum deposit of $10 to activate the offer.
Place a qualifying bet of $20 or more at odds of -500 or longer within seven days.
Earn $50 in FanCash daily for seven consecutive days, totaling $350.
Each day's $50 reward expires 24 hours after it's issued, so use it quickly.

Let's say you place your initial $20 bet on the Rays-Brewers World Series Game 1 matchup. If Tampa Bay's pitching dominates and Milwaukee falls short, you won't hit that first wager, but you'll still unlock your first $50 in FanCash the next day. Alternatively, if the Brewers' powerful lineup breaks through against Drew Rasmussen, your winning bet combines with your daily FanCash rewards to build your bankroll throughout the week.

This Fanatics Sportsbook new-user promo is available only in select states: Arizona, Colorado, Connecticut, D.C., Iowa, Illinois, Indiana, Kansas, Kentucky, Louisiana, Massachusetts, Maryland, Michigan, Missouri, North Carolina, New Jersey, Ohio, Pennsylvania, Tennessee, Virginia, Vermont, West Virginia, and Wyoming. The offer is not available in New York. Your FanCash bonus expires after seven days, so plan your bets strategically across Friday's World Series opener, Saturday's marquee college football matchups, and the full NBA slate.
