The Fanatics Sportsbook promo code SIBONUS is available Thursday, July 23, and new users can claim up to $1,000 in FanCash over their first 10 days. Use today's Twins vs. Guardians matchup as your day-one bet to get started.

How the Fanatics Sportsbook promo code works for Twins vs. Guardians

The Fanatics Sportsbook promo gives new users a straightforward way to get into the action. Place a wager of at least $1 on any market at odds of -500 or longer, and if that bet loses, you get your stake back in FanCash, up to $100. Thursday's series finale between Minnesota and Cleveland is a natural starting point.

Say you back Gavin Williams and the Guardians on the moneyline and Cleveland falls short again after Wednesday's 10-6 loss. Your qualifying wager comes back as FanCash, up to $100. On the other hand, if you side with Taj Bradley and the Twins and Minnesota pulls off the win, you keep the profits with no FanCash needed. Either way, your first day is covered.

Here are the key terms to keep in mind for this Fanatics Sportsbook new-user promo:

  • Available to new users only who register with promo code SIBONUS.
  • A minimum deposit of $10 is required to activate the offer.
  • Place at least $1 on any market at odds of -500 or longer.

  • FanCash carries a 1x playthrough requirement before withdrawal.
  • Bonus FanCash expires seven days after it is issued.
