The point spread is the projected number of points that separate two teams. A game with a spread will have a favorite (the team expected to win) and an underdog (the team expected to lose). A favorite “gives” points and is identified with a minus sign next to their point spread. The underdog “gets” points and is identified with a plus sign next to their point spread.
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.
Obviously, the first three letters on the top two lines of the three-line package of symbols represents a team in the game you’re wagering on; NYG stands for the New York Giants, while DAL stands for the Dallas Cowboys. The number next to each team’s name is known as the spread or the point spread. Wagers on the point spread are among the most popular sports wagers in the world. The reason this wager is popular is that it doesn’t matter which team wins or loses; what matters is the amount of points the teams score, and whether or not the team you place your money on beats the difference in points (the ‘spread’) or not.
Now for American Style Sports Odds. Typically, when you are betting on the point spread, as in topic #1 above, the odds are displayed or implied to be (-110), which is known as American Style odds. The American Style odds format is based on $100. When the number, is displayed as a negative number (-110), it indicates how much money you must risk to realize a profit of $100. In our scenario, you must wager $110 to win $100 profit. If you do, you will receive $210 when you cash in…the winning amount PLUS your initial wager amount.
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.
A parlay basically combines several different wagers into one. For example, a parlay could be made up of five point spread wagers on five separate games. The payout for such a wager could be very attractive, but only if ALL the wagers were correct. Just one wrong pick would mean the whole wager failing. That's why these are considered quite risky. They're a bit more complex than the previous wagers mentioned, but we won't go into any more detail here. We do on the following page though.
The bookmaker functions as a market maker for sports wagers, most of which have a binary outcome: a team either wins or loses. The bookmaker accepts both wagers, and maintains a spread (the vigorish) which will ensure a profit regardless of the outcome of the wager. The Federal Wire Act of 1961 was an attempt by the US government to prevent illegal bookmaking. However, this Act does not apply to other types of online gambling. The Supreme Court has not ruled on the meaning of the Federal Wire Act as it pertains to online gambling.
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.
It's also important to consider whether or not there's any correlation between the point spread and the betting total. If they are, a parlay wager is a good way to get maximum value. For example, a college football point spread +24.5 parlayed with under 48 points in the same game might be a great parlay bet. If the +24.5 team covers the point spread, then there's an increased chance that the game also goes under the posted total of 48.
Spread betting are wagers that are made against the spread. The spread, or line, is a number assigned by the bookmakers which handicaps one team and favors another when two teams play each other and one is perceived as being more likely to win. The favorite "takes" points from the final score and the underdog "gives" points. This number can also be in increments of half-a-point (.5) even though very few sports have .5 point scoring (i.e., The Ryder Cup)
Sometimes the decimal point is left out, so 120 is the same as 1.20. If you want to bet on the favored team, the White Sox, you have to bet $1.20 for every $1 you want to win. If you want to bet on the underdog Astros, you have to bet $1 for every $1.10 you want to win. This is known as the dime line, because ten cents separate the favorite from the underdog. Most bookies offer a dime line, although it can increase to a 20 cent line or greater if one team is heavily favored.
In February 2011, FDU's PublicMind released a poll which showed that half (55%) of voters agreed "that people bet on sports games anyway, so government should allow it and tax it." On the other hand, approximately (37%) of New Jersey voters concurred that betting on sports is "a bad idea because it promotes too much gambling and can corrupt sports." Again, by a significant margin (70%-26%), voters who already engage in sports betting in office pools tend to be more supportive of legal sports betting than other voters.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value. The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
For the player who wagers on San Francisco -5, San Fran must win by more than 5 points for this to be a winning bet. For the player who wagers on St. Louis +5, they must either win the game or lose by less than 5 points for this to be a winning bet. If the outcome falls on the number, the bet is declared a “Push” and your original stake amount gets refunded.
This is where you simply wager on which team will win the game outright, no point spreads, no BS…just the straight up winner. Although this may appear to be easier, you will pay for it as the odds (payout) will reflect the lack of a point spread. If you wager on a favorite, then you will win less than with a point spread, but if you wager on the underdog…and win…you will receive and even greater win amount based on the higher risk taken.
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.
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.
Here in this point spread example for the NFL, the Falcons are playing the Panthers. Atlanta has been set as a three-point favorite on the betting line. That means that for Atlanta to cover the spread that has been set, they will need to win by at least four points. And for Carolina to cover the point spread, they can do so with a loss by two points or less, or obviously a win straight up. If the Falcons win by exactly three points, the bet would result in a push with no payouts.
In this instance, the Dodgers are the favored team, as signified by the negative numeral. It would cost you $130 in order to collect a $100 payout on a Dodgers victory (plus the original wager of $130). But if you bet $100 on the Cubs, you'd collect $120 if they win (plus the original wager). In other words, you'll have to wager more money on Los Angeles than you would Chicago in order collect $100 on a bet.
