A total, or over/under, is a bet on the total amount of points scored in a game by both teams combined. A bet on the over means that both teams must combine to score more than the indicated point total, whereas a bet on the under means that they must combine for less. If the teams combine for exactly the indicated total, then the wager is a tie (or push) and all bets are voided and the bettor gets his money back. For example, in the Philadelphia vs New England matchup with a total of 40.5, you may see the odds laid out like this: 48.5 OVER -110, 48.5 UNDER +105. To wager the over, you have to bet $110 to win $100. To wager the under, you get to bet $100 for the chance to win $105.
