Sports betting has been around since 1000 B.C in China, where betting on animal fights was commonplace. In ancient Rome, one could wager on the Gladiatorial games. The idea of betting on sports is as old as organized sport itself. But up until the 1940s, bettors were fairly limited in what kind of bets they could make. The standard system of odds would allow bets on, for example, the 3-1 odds that the Steelers would beat the Browns.


How the point spread works - When two teams meet on the playing field or on the basketball court, one team is typically better than the other or in a more favorable position because of factors like playing at home. If all you had to do were pick the winning team in a game, everybody would simply wager on the best team or the home team in a even matchup and bypass all the lines and collect their winnings at a high rate.
For example, the Golden State money line above is listed at -340 odds. Using the same principles we just discussed, $340 needs to be bet in order to win $100. Again, this is just the bet to winnings ratio - $34 will win $10, $17 will win $5, $20 will win $5.88, etc. This may seem unfair at first but it is logical. The Warriors are by far the best team in the league and have a much better chance of winning the game. Therefore, sportsbooks even this out by placing the odds at a high price for bettors to win a little.
When it's not NFL season, BetOnline keeps on chugging along with point spreads for numerous other sports including men's + women's basketball (pro + college), along with run lines for baseball (full game + 5-inning), and they even have goal lines for several hockey leagues worldwide. BetOnline excels when it comes to betting on any sport, visit them today and give them a chance to prove it...it will not cost a cent!
Several factors influence a point spread. It starts with power rankings. The media creates power rankings throughout the year, but those can be entirely subjective based more on feelings and emotions than actual raw data. An oddsmaker creates power rankings based on a host of statistics, some more complex than others. The rankings will include record, strength of schedule, and various offensive, defensive, and special teams metrics. They might use Football Outsiders’ efficiency metrics, they might use expected points added, or they might use a host of other internal and external options. The idea being to develop as objective an assessment as possible as to how good or bad a given team is compared to the rest of the NFL.
Point Spread – This is the margin of victory for a game determined by the oddsmaker. Sportsbooks use this to create action on both teams. The favorite will have to win by more than the margin the oddsmakers set. If the Broncos are favored by 2.5 against the 49ers, they must win by 3 points or more for a win. If they only win by 2, they didn’t cover the spread and those who bet the 49ers will win.
You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.

Using the Patriots-Rams Super Bowl matchup as our example, the Patriots are listed by most sportsbooks as a 2.5-point favorite. The Patriots are listed at -2.5, while the Rams are listed at +2.5. If you bet on the Patriots to cover the spread and they win by three points or more, you win. If you bet on the Rams to cover the spread and they lost by less than three points or win the game, you win.

Absolutely. When the lines go up for the NFL, or for the first game of the NCAA men’s basketball tournament, there are several days in between the open and the game itself where movement can take place. You’ll find that the betting public tends to pile in on their favorite teams once they get home from work on Friday. You can anticipate these line movements and time your bet accordingly to take advantage.

First, however, a word of caution: Sports betting can be a fun and profitable venture. However, like most good things in life there are pitfalls to be aware of. You should be able to enjoy many positive experiences as long as you bet in moderation and under control. We know you have heard this before but it definitely bears repeating: don’t bet money you can’t afford to lose, either emotionally or financially. If you or someone you know shows signs of compulsive gambling, one place to find help is Gamblers Anonymous.
Another way to beat football point spreads is to shop for off market prices. For example, let's say you're shopping online betting sites and see every site is offering Vikings +7.0. Then, you stumble upon one site that's offering +7.5. There's a good chance that this is a +EV wager, simply because it is out of sync with every other site. Please note that this strategy isn't quite the same as simply shopping for the best lines. Here, you're specifically looking for wagers that are +EV because they're against the market.

In a different study released by FDU’s PublicMind in October 2011, results showed that New Jersey voters thought legalizing sports betting in New Jersey was a good idea. Half of New Jersey voters (52%) said that they approved the idea of legalizing sports betting at Atlantic City casinos and racetracks, 31% opposed it. In addition, there was a significant gender split: a majority of men approved of the idea by a wide margin (65-21), while only 39% of women approved and 41% opposed.[9] The October results were stable, reflecting an earlier poll in April 2011 where New Jersey voters approved the legalization of sports betting in the state by a margin of 53%-30%. However, nearly two-thirds (66%) of voters were not aware of the upcoming statewide referendum on the issue. Age proved to be a divide: voters between the ages 18 and 34 were more likely to approve of sports betting than were older voters. Dr. Woolley commented: "But... younger voters... are far less likely to vote than other voters... As always, a lot depends on who actually shows up to vote."[10]
A quick word on that annoying half point in the point spread – most lines you’ll come across will use half points, but it’s not standard practice across the board. When you see a line with a full number instead of a number with a half point, your wager could end up as a push. In our example, if the line were 7 instead of 7.5 and the final difference in points was exactly 7, your wager is returned to you, and neither you nor the book makes money.
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 -110 listed is the actual odds given for these bets, and the odds determine how much you win based on the amount of your wager. This is why the odds are often called the price of a bet. When you see -110 odds, you need to bet $110 to win $100. Of course, you don't need to literally bet $110; that is just the ratio of the amount bet to the amount won. You can bet $11 to win $10, $20 to win $18.18, etc.
If you're new to football betting and keen to get involved then you've just come to exactly the right place. On this page we will teach you all the basics of betting on football, and make sure that you are on the right track from the moment you place your first wager. If you feel like you're ready to dive right in, here are the top football betting sites we reccomend:
Moneyline (ML) – form of wagering typically used in baseball and hockey, which replaces the point spread, but also popular in basketball especially for picking underdogs. The team you choose only has to win the game, not win by a certain number of points. The negative value still indicates the favorite (-150) and the positive value indicates the underdog (+130). It's easiest to picture the number 100 sitting in the middle of these two values. For example, if you want to bet a -150 favorite, you would wager $150 in order to win $100. On the underdog, you would risk $100 and win $130 if the underdog wins. It's a simple way to have the risk-reward scenario.
Making money from betting on any sport requires an understanding of how the betting markets work, and an ability to use that knowledge to gain an advantage. No-one makes a consistent profit from simply following hunches or relying purely on statistics and trends. Sports handicapping is something that people often assume is very complicated, but the basics are actually relatively easy to grasp.
The punter usually receives all dividends and other corporate adjustments in the financing charge each night. For example, suppose Lloyds Bank goes ex-dividend with dividend of 23.5p. The bettor receives that amount. The exact amount received varies depending on the rules and policies of the spread betting company, and the taxes that are normally charged in the home tax country of the shares.

The optimal situation for bookmakers is to set odds that will attract an equal amount of money on both sides, thus limiting their exposure to any one particular result. To further explain, consider two people make a bet on each side of a game without a bookmaker. Each risks $110, meaning there is $220 to be won. The winner of that bet will receive all $220. However, if he had made that $110 bet through a bookmaker he would have only won $100 because of the vig. In a perfect world if all bookmaker action was balanced, they would be guaranteed a nice profit because of the vig. 

If a team favored by six points wins by exactly six points, the outcome is considered a "push" and the bettors get their money back, minus the bookmaker's commission. To reduce the number of pushes, oddsmakers often set spreads with half-points. So if the Cowboys are 3 1/2- or 3.5-point favorites over the Giants, they must prevail by four or more points to pay winning bets.

Another form of futures betting involves the over/under on the number of games a particular team will win in the regular season. This type of wager is typically found on pro football and major league baseball, and sometimes on pro basketball. For example, the over/under on the Yankees may be 93 wins. If the Yankees go on to win 94 or more games, the "over" is a winner. If they win 92 or fewer games, the "under" is a winner. If they win exactly 93, the bet is a push and tickets are refunded.


There are very few periods of time throughout the year when there isn't a game or event that is garnering national media attention and bettors are clamoring to lay down a wager. Off the top of my head, the only period I can think of is during the MLB All-Star break, where it's slim pickings to lay down a wager. Sure, the Home Run Derby and All-Star game are closely watched and people do bet on them, but it's done more so to have a little action on the game to make it semi-watchable. However, the rest of the year is littered with massive, high-stakes, high-drama type events. These are what the industry called "hot games" Read More >>
Oddsmakers do more than pick the winners and losers of each game. They weigh myriad factors to determine which team is favored by how many points. They set an early point spread on each game, then adjust it up or down based on betting patterns. If the Dallas Cowboys are 6-point favorites over the New York Giants, they must win by seven or more points to pay off winning bets. If you wagered on the Giants, you win your bet if New York either beats Dallas outright or loses by five points or fewer.
To show how this can be exploited, take a point spread of -8.5 at odds of -110. This is a 50/50 proposition. Let's assume you've purchased enough points to move the spread to -6.5 at odds of -150. Now, you'd win instead of lose 6.24% of the time they win by 8, and 6.59% of the time they win by 7. Add these together with the 50% from the original proposition, and we get 62.83%.
The most important thing you can teach yourself early on is: "Just because the books assign one side to be the favorite (even large, -200 or -300, favorites), does not mean that they will win." We have all seen favorites get upset, and it is important to avoid the temptation of finding comfort in the fact that the lines makers put one team as a favorite.

There is no such thing as a half point in sports, but there is in sports betting!  The half point ensures that a side will win and that the match will not end in a push, where the spread equals the actual difference in points between the two teams.  In a push all bettors get their money back, which is no good for the oddsmaker!  Half points also give oddsmakers more control over lines, allowing them to set more specific values.
Generally, the number next to the spread is “-110”. This is what’s known as the juice, vig or odds. The juice is a fraction of the wager taken from the bettor if the bet wins. In this instance, a winning wager of $110 will yield a profit of $100.The example above demonstrates that, although Indianapolis won the contest, Tennessee covered the spread by losing by less than nine points. An important aspect of sports betting is capturing the best line possible. A great way to achieve this is by shopping for the best line.
According to an article in The Times dated 10 April 2009, approximately 30,000 spread bet accounts were opened in the previous year, and that the largest study of gambling in the UK on behalf of the Gambling Commission found that serious problems developed in almost 15% of spread betters compared to 1% of other gambling.[7] A report from Cass Business School found that only 1 in 5 gamblers ends up a winner.[8] As noted in the report, this corresponds to the same ratio of successful gamblers in regular trading.[9] Evidence from spread betting firms themselves actually put this closer to being 1 in 10 traders as being profitable, with a high number of clients suffering from the volatility that is supposed to be one of the benefits of spread betting.[citation needed]

Sports betting has resulted in a number of scandals in sport, affecting the integrity of sports events through various acts including point shaving (players affecting the score by missing shots), spot-fixing (a player action is fixed), bad calls from officials at key moments, and overall match fixing (the overall result of the event is fixed). Examples include the 1919 World Series, the alleged (and later admitted) illegal gambling of former MLB player Pete Rose, and former NBA referee Tim Donaghy.

Money Line: More common in baseball and hockey, pro football moneylines are growing in popularity. There is no spread, so your team just needs to win the game, not win by a certain number of points. The negative value means a favorite (-190) and a positive one indicates an underdog (+170). Picture the number 100 sitting in between these two values. Example: if you want to pick a -190 favorite, you must risk $190 in order to win $100. To back a +170 underdog, you put up $100 and win $170 if the dog wins. In some cases, betting moneylines is actually better value and can provide a bigger profit for less risk.
