Betting on the point spread is determinant on how many points a team wins or loses by. Take the following example:
- Lions +6.5 (-110)
- Rams -6.5 (-110)
In this example, Detroit is an underdog by 6.5 points, indicated by “+6.5.” If the Lions keep the game within seven or win outright– say they lost 27-24– then the Lions (+6.5) win the bet and would have a total payout of $19.09 on a $10 bet ($9.09 in profit). If the Rams manage to win by seven or more– say 31-17– then the Rams (-6.5) would win, and the payout would be the same as listed above.
