They do this by manipulating the lines to entice action where they need it. If they have too much action coming in on one team, they will adjust the lines to pay out less for that team to deter more bets. At the same time, they will adjust the line for the other team to pay out more to entice more action on that side. This dance continues until the game starts to try and get the correct amount of money on each side of the contest.
We're often asked a question along the lines of "why would I place moneyline wagers rather than point spread wagers?" There's no simple answer to this question really, as point spreads and moneylines shouldn't be viewed as "either/or" options as such. You don't have to decide that you're always going to bet on the spread, or that you're always going to bet moneylines. These are two different wager types that have their own merits, and any bettor should have them both in their arsenal.
When a betting line is listed, it will contain the moneyline and spread information. If there are two teams and there is a spread of +6 and -6, betting on the favorite, which is the – spread, the score must be greater than the underdog’s score to win. For example. The score between the Patriots and Bengals is 20 to 10. So, 20-4 is 14, which is greater than the 10 points earned by the underdog, so the bet will win.
For example, if you’re betting on teams A, B, and C to win outright, you’ll have two round robin options available. Your By 2’s option includes all possible 2-team parlays for these three wagers (A+B, B+C, and A+C). And your By 3’s option includes all possible 3-team parlays on these 3 wagers (A+B+C). If you wager $30 on the By 2’s option, that money will be split evenly among the 2-team parlays ($10 on each of the 3 wagers).
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.
The last format we want to look at is fractional odds. Personally, we aren’t a huge fan of fractional odds because they’re the most challenging to work with. The formula is almost the same as with decimal odds, but it gives your profit instead of total money returned. It also requires you to solve a fraction, which may be a nightmare for a lot of people. Regardless, we are going to walk you through how to do it with the same bet we’ve been working with.
Let us be clear before we go any further with this strategy tip. If there is value in a bet, go ahead and make it. What we want to talk about, though, are bets where you are risking an abnormally high amount of money to win a very small amount of money. While this is still technically profitable, you might not get enough opportunities to push through the variance and realize your value.
Single day matchups are wagers on the complete 18-holes for that day. Holes played as part of a completion from the previous day's round, and playoff holes are not included in Single Day matchups. The full 18 holes will be considered in determining the outcome of the bet even if they are played on consecutive days. If both members of the matchup do not complete the full 18 holes, all bets are "No Action". If both players end the 18 holes in a tie, the bet is considered a "No Action" wager.

For each NFL game the oddsmakers set a number of points in which the favored team is favored by. Bettors can then either choose for the favored team to win by more than the number of points set, or bet on the underdogs to lose by less than the number of points they are underdogs by or win the game straight up. For example, the spread could be set on the favored team at 6.5 points. This would mean in order for a bet on the favored team on the spread to win they would need to win by more than 6.5 points (7 or more) in order to win the bet. It also means that a bet on the underdog team would win if the underdogs lost by less than 6.5 points (6 or less) or won the game outright.
Bookmaker's interest - In order to guarantee a profit for the house, a bookie needs to create even action on both sides of a particular game. In a perfect world the bookie would have 50 percent of the handle come in on the underdog and 50 percent on the favorite. This ensures that the sports books are guaranteed a profit because of the 10 percent commission or "vigorish" charged on most sports wagers. This is why there is "movement" on the point spread. If one side on a game is being bet more heavily, the bookie must move the number in order to attract interest on the other side in order to balance action.
If the bookmaker was only confident enough to give Seattle a field goal’s lead on the Patriots, it was clearly going to be a tight game. Oddsmakers aren’t often that wrong about flagship games like the Super Bowl. All things being equal, it’s likely the betting public would have taken the Seahawks to win the game and have been done with it. But throw in the point spread that gave the Patriots 2.5 points, and the proposition seems more equal.
In North American sports betting many of these wagers would be classified as over-under (or, more commonly today, total) bets rather than spread bets. However, these are for one side or another of a total only, and do not increase the amount won or lost as the actual moves away from the bookmaker's prediction. Instead, over-under or total bets are handled much like point-spread bets on a team, with the usual 10/11 (4.55%) commission applied. Many Nevada sports books allow these bets in parlays, just like team point spread bets. This makes it possible to bet, for instance, team A and the over, and be paid if both team A "covers" the point spread and the total score is higher than the book's prediction. (Such parlays usually pay off at odds of 13:5 with no commission charge, just as a standard two-team parlay would.)
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.
