How the Fanatics Sportsbook promo code works for Rams vs Broncos

The Fanatics Sportsbook promo gives new bettors a chance to earn bonus funds across their first 10 days. You'll place a wager of at least $1 on any market with odds of minus 500 or longer, and if your bet loses, you'll receive your stake back as FanCash, up to $100 per day. This means you can repeat the offer daily for 10 consecutive days, potentially earning up to $1,000 in total bonus funds.

For the Rams-Broncos game, imagine you place a $50 wager on the Rams to cover the spread at minus 110 odds. If the Broncos pull off the upset and your bet loses, you'll get $50 in FanCash credited to your account. Conversely, if your bet wins, you keep your winnings and can use them to place more wagers throughout the week. The bonus funds expire after seven days, so you'll want to use them promptly on upcoming games.
