When betting the point spread, there is almost always a winner and a loser. However, in some instances sportsbook decide to put out a whole number such as -3 for bettors to bet on. If the final score ends with a differential of three points - no matter who wins - the bet is considered a "push" and all money is refunded to both sides since neither team covered the spread.
You can never rule out the weather in sports. If there is a team or contestant who does better in certain conditions but worse in others, you’re going to see a line movement if the conditions change. For example, a football team that has a strong passing attack might become less of a favorite if rain pops up in the forecast. Often, the line does not shift as quickly as it should in response to changing weather conditions, which can create some good opportunities to find value.
Let’s take a quick step back and talk about what the sportsbook’s goal is with any game they are offering action on. Ideally, the sportsbook wants to take the perfect amount of action (money bet) on each side of a game so that regardless of who wins, they make money. Their profit comes from taking a small percentage off of the top as a house fee for facilitating the action.
With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.
The last number in the top two rows of our sports line example is known as the money line. If you’re not interested in betting on the point spread, you can wager on a team to win outright. The plus sign next to the underdog (in our case, the Giants) indicates how much money you’ll earn for every $100 you bet on the money line. Conversely, the minus sign next to the favorite’s line tells you how much you have to wager in order to win $100. In our example, a $100 wager on the Giants earns you $300 should they pull off the upset, while a bet of $405 on the Cowboys will net you an extra $100. Representing odds in units of $100 makes placing different size bets easy; if you want to bet $10 on the Giants, you stand to earn $30 if they win, while a $40.50 bet on the Cowboys will net you an additional $10.
While we're going to cover this extensively in the moneyline section of the Basketball Betting Guide, we'll touch briefly on what the -110 means here. -110 refers to the moneyline payout for a particular bet. If you were to bet $100 on a basketball point spread paying -110 and win, you would be paid out a profit of $90.90. The easy way to figure out the amount you will get paid with minus moneyline odds is to divide your bet size by the absolute value of the betting odds and multiply that number by 100.
You may have heard the term “covering the spread” or the phrase “betting against the spread.” This means that if the favorite team wins an event with the point spread taken into account or that the underdog team wins with additional points, they have covered the spread. If the Packers win that game by more than 7 points, they have covered the spread.
