Monday, Oct. 12 brings a loaded sports slate, and the $350 in FanCash welcome offer from Fanatics makes it the perfect time to start betting. New users can claim this Fanatics Sportsbook promo code offer and place their first wagers on the Bills-Rams matchup or any of the MLB playoff games happening throughout the day.

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

The Fanatics Sportsbook promo is straightforward: deposit at least $10, place a $20 wager at odds of -500 or longer, and you'll unlock $50 in FanCash daily for seven consecutive days. That adds up to $350 total in bonus funds to use across all the action on Monday and beyond. The Bills-Rams game offers plenty of betting angles, from Josh Allen's passing yards to the Rams' turnover issues, making it an ideal target for your initial $20 bet.

Here are the key terms and conditions for this Fanatics Sportsbook new-user promo:

  • Available in AZ, CO, CT, DC, IA, IL, IN, KS, KY, LA, MA, MD, MI, MO, NC, NJ, OH, PA, TN, VA, VT, WV, and WY.
  • Not available in New York.
  • Minimum deposit of $10 required to activate the bonus.
  • Place a $20 or greater wager at minimum odds of -500 within seven days of signing up.
  • Earn $50 in FanCash each day for seven days, totaling $350.
  • Each day's FanCash reward expires 24 hours after it's issued.
  • FanCash is non-withdrawable bonus credit.

If you bet $20 on the Bills to cover the spread and they win, you'll pocket your winnings plus unlock your first $50 in FanCash. If the Rams pull off the upset, you still get that $50 in FanCash to use on the Dodgers-Brewers or Guardians-Rays games happening the same evening. The beauty of this offer is that you have multiple betting opportunities throughout Monday to maximize your bonus funds.

Fanatics offers competitive sportsbook promos regularly, and this welcome bonus is one of the most generous available. The seven-day structure means you can spread your bonus funds across multiple games and matchups, giving you flexibility to find the best betting opportunities.
