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.
Parlays - these might be the most popular bets out there, especially among novice and amateur bettors, perhaps because of the lure of betting a small amount for a potentially big payoff. But they are fool's gold at best. Parlays involve wagering on two or more games on the same bet following the casino's pre-determined payout scale. Each game on a parlay must win for the bet to be a winner.
Above, you can see several numbers to the right of both teams. These all represent the different lines that are available on the San Francisco vs. Los Angeles game. The first set of numbers for both teams is the point spread, the second set is the moneyline, and the third set is the over/under (a.k.a. totals). We'll explain each of these lines more in-depth below.
With some betting sites odds, certain games are priced differently than risking $1.10 to win $1.00 (which is called -110 odds). For example, you might see the Giants priced at -105 and +7 in a game against the Jets. Now, you only have to risk $1.05 to win $1.00. This is obviously better odds, but it's very likely that they will lose by exactly seven to give you a push. Taking -110 and +7.5 with an alternative bookmaker is actually the better bet.
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. A report from Cass Business School found that only 1 in 5 gamblers ends up a winner. As noted in the report, this corresponds to the same ratio of successful gamblers in regular trading. 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.
Identify the favorite. Lines with a - before the number (i.e. -200) indicate the favorite. A -200 should be read as: "For every $200 wagered, I win $100." When there is a negative sign, the line should always be read with relation to 100. That does not mean you have to bet that much, it's just easiest to understand! When a + sign is present, just reverse the reading, always keeping reference to 100:
Since betting on point spreads in the NFL is the most popular bet that people make, it is probably pretty important that you know what you are doing. The point spreads in the NFL are always alot closer then college football because you are dealing with the best of the best. You will almost never see a team favored by more then two touchdowns in the NFL, and most of the NFL point spreads are less then one touchdown. So, here is are best try at helping you understand how to read point spreads in NFL games.
Point spreads are used since most recreational bettors prefer to wager even money propositions. In the above example, if there was no point spread, only moneyline betting would exist. So, if odds makers are giving the New England Patriots a 73% chance of winning a game, then in order to take bets and still have a small profit margin, the bookmaker would have no choice but to require Patriot bettors to stake $3.00 or more for each $1.00 they want to win.
With money line bets the goal is to pick the outright winner of a game or event without the use of a point spread. While money line betting is available for sports where point spreads are used, they’re most popular in sports like baseball and soccer where very few points are scored. Money lines are also used for sports where points do not determine the winner or loser, as in auto racing or tennis.
You’ll need to know how the rotation number, point spread, moneyline and over/under are used and what each means. Each of these terms may be called by another name. The rotation number if often referred to as the number or the rotation mark, moneyline becomes line, point spread is called the spread, and over/under becomes the total. When you come down to it, these are the major terms that can be lumped under the heading odds.
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.
This means that the people betting the big bucks are going to end up shifting the line considerably. A lot of times, you will see a moneyline released, and then it will quickly shift. Usually, this is a skilled big bettor taking advantage of what they think is an opportunity. Ideally, you’ll want to jump on bets before these skilled bettors get ahold of it.
Betting against the spread - In the sports betting industry the acronym ATS is used to label a team's record when betting against the spread. ATS records are a valuable tool in sports handicapping. A team may be playing great straight-up, winning a lot of games but at the same time they could have a dreadful ATS record because they are overvalued by the general public and the oddsmakers. And, conversely, a team could be losing a lot of games but playing in a lot of close games as underdogs and have a good ATS record going.
The biggest advantage of the moneyline for the NBA is that your team doesn't have to overcome the point spread for you to win your game. If your handicapping leads you to believe that one team is likely to win but you can be less certain that they will win by as much as the point spread then the moneyline may be attractive. You are sacrificing some potential return because the moneyline won't pay as much for the favorite as the point spread will, but it's obviously better to make a small profit than it is to lose a bet. This is particularly attractive in basketball because the favorites can often face large point spreads and teams can win comfortably and effectively without covering the spread.
Point spread lines can be tricky in the fact that they can help shape our views of a game just by looking at them. You may have no opinion of a game until you look at a point spread and then your brain immediately starts looking for evidence to back up the line. This can cause you to build your view of a game off of what the sportsbook thinks and not what you think. The best advice here is to have an idea of what you think the line is before you look at the sportsbook's lines. This will protect you from being influenced by what they came up with and help you to spot bad lines.
Another thing to consider is popular winning margins, which are particularly applicable to football. Consider that many tight games may finish with either a three point or a seven point margin. If the point spread is around either of these marks, make every attempt to be the right side. For example, if you were to back a team that is either 2.5 or 3 point favorites, you’d want to back them at the 2.5 mark, as if they were to win by 3 you’d win as opposed to a push.
Linemakers who work for the sportsbooks must put out lines that will entice the "favorite" bettors to lay the points and take the favorite or entice the underdog bettors to take the points with the underdog. Because each sportsbook is operated under their own rules, guidelines and stipulations, they are free to put out whatever line they feel is competitive and charge whatever vig they want to based on how much action that specific line is taking.
Let's use our example from earlier, but this time let's say you think that Florida will cover the -7 spread. Should you place this bet? Maybe. Yes, this is good value bet and one that you should bet, but maybe not right away. Let's say you think the public is improperly going to dump a lot of money onto Arkansas. If this happens and you wait to place your bet, the line might move in your favor. By waiting, you may be able to get Florida at -6.5 to win. This means that if you bet right away, you would only tie if they won by seven points. By waiting, you will win your bet now if Florida wins the game by seven points.
This is a very common occurrence in sports betting and sportsbooks have the full right to shift the spread or odds for any given match prior to it starting. Many factors can influence a change of the spread such as injuries, the number of bets coming in for either team or the weather, to name a few. Depending on the timing of placing the bet, the bettor can also have an advantage or a disadvantage depending on which way the spread has shifted.
