Let's say you place a $20 bet on the Packers to cover the spread in Thursday's matchup. If Green Bay wins and covers, you'll collect your winnings and unlock your first $50 in FanCash. If the bet doesn't hit, you still earn that initial $50 in FanCash the next day, allowing you to continue building your bonus through the week. The beauty of sportsbook promos like this is that you're earning bonus credit regardless of individual bet outcomes.
You have seven days from your initial qualifying wager to complete the bonus structure. Since the Carolina-Green Bay game kicks off at 8:15 PM ET on Thursday, you can place your opening bet that evening and begin accumulating your daily FanCash rewards immediately.
