How the Fanatics Sportsbook promo code works for NBA Cup group play
The Fanatics Sportsbook promo offers new users a straightforward path to earning bonus funds. After registering with code SIBONUS350 and making a minimum $10 deposit, you'll place a $20 wager at odds of -500 or longer on any sports market. Once you complete that initial bet on the New York vs. Philadelphia game or any other NBA Cup matchup, you'll unlock $50 in FanCash daily for seven consecutive days, totaling $350 in bonus funds.
Here's what you need to know about the terms and conditions for this offer:
- This Fanatics Sportsbook sign-up bonus is available only to new users without an existing account.
- You must use promo code SIBONUS350 during registration to activate the offer.
- A minimum deposit of $10 is required to qualify.
- Your initial qualifying bet must be $20 or more at minimum odds of -500.
- You'll earn $50 in FanCash each day for seven days after placing your qualifying bet.
- Each day's FanCash reward expires 24 hours after it's issued, so use it promptly.
- The total bonus expires after seven days if not fully claimed.
Let's look at how this plays out in real scenarios. If you place a $20 bet on New York to beat Philadelphia at -110 odds and win, you'll receive your winnings plus unlock your first $50 in FanCash. If that same bet loses, you still unlock the $50 in FanCash for day one, giving you another chance to build your bankroll. The key is returning daily to place qualifying bets and collect each day's $50 reward before it expires.
When exploring sportsbook promos, you'll find that Fanatics' structure stands out for its simplicity and daily earning potential. The NBA Cup group play slate on Oct. 30 features 10 games, including Houston's undefeated squad facing Dallas at 8 PM ET and the late-night showdown between Denver and Phoenix at 10 PM ET. You have plenty of betting opportunities to meet the daily requirements and maximize your FanCash earnings throughout the week.
