A moneyline wager is a bet on who you think will be the winner of the game. Each moneyline wager has odds attached to both the favorite and the underdog.
For example: Denver Broncos are favored (-270) against the Tampa Buccaneers (+220). If you bet $100.00 on the Broncos, you would be wagering $100.00 to receive a return $137.04 inclusive of the $100 wager. If you wagered $100.00 on Tampa as the underdog, you would receive a return $220.00 if they won the game.
