The point spread is essentially a handicap towards the underdog. The wager becomes "Will the favorite win by more than the point spread?" The point spread can be moved to any level to create an equal number of participants on each side of the wager. This allows a bookmaker to act as a market maker by accepting wagers on both sides of the spread. The bookmaker charges a commission, or vigorish, and acts as the counterparty for each participant. As long as the total amount wagered on each side is roughly equal, the bookmaker is unconcerned with the actual outcome; profits instead come from the commissions.
Let's say you decide to bet $100 on Liverpool, and they lose the game by two goals. You would push on the first half of your bet and win the second half of your bet. You would receive your $50 back for the push and $43.48 in profit on your second bet. Basically, the sportsbook would hand you back $143.48 total, which would include $50 for the push, $50 for your original bet, and $43.48 for the push.
Let’s say that a ton of bets pour in on the Mavericks. In order to encourage more bets on the Celtics and even things out, they might move the line to 5 ½. This means that a bet on the Mavericks would now win only if they won by more than 5 ½ points instead of 4 ½. This would discourage more people from betting on the Mavericks, as they would have to perform much better to get you the victory.
We already mentioned how using multiple betting sites allows you to take advantage of multiple bonus offers. That's not the only benefit either. Since point spreads vary between sites, one of the best ways to beat these wagers is to compare the different spreads in order to find which one is the most favorable. This doesn't take nearly as long as you might think, and it will make a huge difference to your bottom line over time.
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 number that follows the plus or minus sign will indicate how big of a favorite or an underdog the team is. The larger the number is, the bigger the favorite or the underdog the team is. For example, a team that is -300 is a bigger favorite than a team that is -150. A team that is +240 is a bigger underdog than a team that is +130. Remember, this is not the sportsbook’s actual prediction on who they think will win; it’s in relation to the money that has been bet on the game. It is more depictive of who the betting public thinks is going to win the game.
Easily the most popular type of betting for NFL football is “spread” betting or more commonly known as betting against the spread. Bettors who are new to NFL betting or betting in general may be a little confused with NFL spread betting, but it is pretty easy to understand once it is explained to you. We will explain what betting against the spread means below.

If all the money at one sportsbook comes in on Team A and all the money comes into a second sportsbook on Team B, they’re both going to adjust their lines accordingly to what is going on in their book. This means that if you want to bet on Team A, you should go to the second sportsbook where the line will be great. If you want to be on Team B, you should go to the first sportsbook where the line will be better.
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.

Especially in major tournaments, some sports books offer odds on unusual golf propositions, such as the over/under on the winning score, the over/under on the lowest round by any golfer or the over/under on the finishing position by a particular golfer. For example, the over/under on Woods' finishing position may be 3 1/2. If he finishes first, second or third in the tournament, the "under" wins; if he finishes fourth or worse, the "over" tickets cash.
The most important takeaway is the actual pointspread, which is seven points in this example. The plus sign is always in front of the spread for the underdog and the minus sign is used to signify the favorite. Next to the pointspread in this example is (-110). This number reflects the actual commission (or juice) that the sportsbook is charging to book this bet. If you wager $100 on New England as the favorite and the Patriots go on to win my more than seven points, you would win $100. If they won by fewer than seven points or lost the game outright, you would owe this betting outlet $110. If New England wins by exactly seven points, the bet is considered to be a PUSH and no money exchanges hands. You only pay the 10 percent commission on losing bets.

The level of the gambler’s profit or loss will be determined by the stake size selected for the bet, multiplied by the number of unit points above or below the gambler’s bet level. This reflects the fundamental difference between sports spread betting and fixed odds sports betting in that both the level of winnings and level of losses are not fixed and can end up being many multiples of the original stake size selected.
Proline will set a point spread for each game of either -0.5 / +.05, -1.0 / +1.0, or -1.5 / +1.5. If you choose -0.5 the team must win by 1 goal or more to win your wager. If you choose +0.5 your team must win or tie the game. Note that OLG Proline includes the shoot-out for point spreads so there are never any ties for the -0.5 / +0.5 spreads.  If you choose the -1.0 spread your team must win by 2 or more goals to win the bet. If they win by 1 goal exactly it is a push. If you choose the +1.0 spread your team must win the game by 1 or more goals. If they lose by 1 goal it is a push. If you choose the -1.5 spread your team must win by 2 or more goals. If you choose the +1.5 spread your team must win the game, tie, or lose by 1 goal to win the bet.

It’s common knowledge among bettors that the online gambling industry pays close attention to Las Vegas Sports Consultants, a private company that handles the odds for casinos and newspapers. But the totals I set have to reflect our customers’ preferences for betting the over or under on certain teams in certain situations. Also, because LVSC lines are published early, I have to keep on top of injuries and potential changes in coaching strategy leading up to the game in question before I release any totals. This is doubly important in basketball, where pace determines how many shots will be taken in 48 minutes.


Spread betting has moved outside the ambit of sport and financial markets (that is, those dealing solely with share, bonds and derivatives), to cover a wide range of markets, such as house prices.[5] By paying attention to the external factors, such as weather and time of day, those who are betting using a point spread can be better prepared when it comes to obtaining a favorable outcome. Additionally, by avoiding the favourite-longshot bias, where the expected returns on bets placed at shorter odds exceed that of bets placed at the longer odds, and not betting with one’s favorite team, but rather with the team that has been shown to be better when playing in a specific weather condition and time of day, the possibility of arriving at a positive outcome is increased.
A Parlay is a wager which combines several legs in a wager where the winnings from each selection roll onto the next. For a Parlay to be successful, all individual legs in the Parlay need to be winning selections. In the event of a tie in one of your selections in a parlay, the parlay is reduced to the next lowest number of teams. For example, if you have a 4 team parlay and one of the selections is a tie (only on 2 way markets), the leg would be considered a "push". In this instance, the 4 team parlay would then become a 3 team parlay and would be settled at reduced odds to reflect a winning 3 team parlay.
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.

Some people consider sports gambling a disease which is why it is outlawed everywhere in the United States besides Las Vegas. However, many Americans still bet on sports illegally with various overseas bookies. Because of this, many Americans believe sports gambling should be made legal throughout the United States because the country is missing out on millions of potential tax dollars by sports gamblers using overseas bookies.
Another popular form of golf betting involves matchup propositions, in which two golfers are paired against each other in a head-to-head wager, with a betting line on each golfer set by the oddsmaker. The golfer with the better (lower) score wins the matchup. (If one golfer continues play in the tournament after his opponent misses the cut, the golfer who continues play wins the matchup.)
