Sports betting is the activity of predicting sports results and placing a wager on the outcome. The frequency of sports bet upon varies by culture, with the vast majority of bets being placed on association football, American football, basketball, baseball, hockey, track cycling, auto racing, mixed martial arts, and boxing at both the amateur and professional levels. Sports betting can also extend to non-athletic events, such as reality show contests and political elections, and non-human contests such as horse racing, greyhound racing, and illegal, underground dog fighting.
Even if you’re brand-new to betting on football, you’ve probably seen NFL spreads published in the paper or talked about on TV. The point spread levels the playing field, making betting on either the favorite or the underdog equally attractive. Either the favorite has to win by the margin listed, or the underdog has a buffer to lose the game by that margin, or win it outright.
The Cronje Affair was an India-South Africa Cricket match fixing scandal that went public in 2000.[57] It began in 1996 when the-then captain of the South African national cricket team, Hansie Cronje, was convinced by Mukesh "John" Gupta, an Indian bookmaker, to throw a match during a Test in Kanpur, India. The scheme was discovered when Delhi police recorded illegal dealings between Indian bookmaker Sanjay Chawla and Cronje. According to the Telegraph in 2010, Cronje was paid off a total of £65,000 from Gupta.[58]
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.
If you've ever said the words "best two out of three" when playing a game amongst friends, you are subconsciously making a "series bet." You are betting that during the course of these three games that you will be able to win two games thus emerging victorious. In the sports betting industry, a "series bet" is a betting option that allows you to correctly predict which team will win more games in a particular series and ultimately advance to the next round instead of deciding who will win each individual game.

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.
The wager is that the two teams will combine to score more or less than 43 points. If the total score is 43, then the wager is a push and you get your money back. It doesn’t matter which team scores the points. It could be 24-20 for either teams and “Over” wins the wager. Likewise, the final score could be Jets 45-0 (Yeah!) and the “Over” wins. On the flip side, the score can be 21-20 and the “Under” wins. Likewise, the Jets could win 42-0 (Yeah!) and the “Under” also wins.
Rotation numbers are standard from sportsbook to sportsbook. The number becomes a way to refer to the game and team without mentioning the teams name. It’s a sort of shorthand. Also, the rotation number allows each book to list the games in the same order—numerically. It is, in essence, a way to keep all of the games that are posted each day and throughout the week organized. That makes it easy for the bettor and the bookie.
Point spreads focus on a margin of victory between the two teams and again, what you’re looking for is the positive and negative signs. If there is a minus sign next to a team’s spread, that suggest that they are favored and have to win by or cover that amount. If there is a positive sign, that tells you that they are the underdog and they are getting points. For example: let’s say that the New England Patriots are playing the Buffalo Bills and the Patriots are -5.5 and the Bills are therefore +5.5. If you bet the Patriots, they have to win by six points or more to cover. If you bet the Bills, they can lose by five points or less, or they can win the game outright and you would still win your bet.
The house vigorish - and your chances of winning - get worse with the more teams you add. So while some sportsbooks will let you place a 15-teamer with astronomical odds, you probably have a better chance of being struck by lighting - twice - before winning one. You are much better off sticking to two-team parlays exclusively, if you insist on taking poor odds and placing parlay wagers.

The over/under in this example has been set at 42.5.  If you project the Jets and Patriots to combine to score more than 42.5 points, you would place a wager on the over.  If you think they will score less than 42.5 points, you would bet the under.  Let’s say the final score of this game is Patriots 27, Jets 24.  Which bet would lose and which bet would win?  The sum of all points scored is 27 + 24 = 51, so an over bet wins and an under bet loses.


A few other small factors to look at would include recent matchups between the two teams, home and away records of the two teams, the way the teams have played in the past 3-4 weeks (hot streak/cold streak), and also any injuries to stars that could affect the overall game plan of team.  How does a football team do off a loss, off a win, etc.  Start adding some of these suggestions to your repertoire and I guarantee your sports betting bankroll will keep growing each football season.
What may look like a jumble of words, numbers, and punctuation is actually a precise and easy-to-read breakdown of the various odds and point spread details your book is offering. Here is a breakdown of each unit of information given above. Once you understand each part of the jumbled details above, you’ll be able to read a sports betting line with confidence.
What's the difference between an oddsmaker and a bookie? A bookie's job is purely mechanical. He gets the line from Vegas or another source, offers bets at those odds, then collects money from the losers, pays out to the winners and keeps the vig. Oddsmakers don't actually take bets -- they study the games and set the lines. Bookies often adjust the spreads for their games, so they do a little oddsmaking, and oddsmakers work for casinos, which operate sports books that take bets.

Notice that point spreads adjust the score for the favorite team. This is easiest to see with an example: If the New York Knicks are playing the Boston Celtics, and Boston is favored to win by a 4-point spread, then a bet on Boston only pays out if Boston wins by more than 4 points. A bet on New York pays out if New York wins or if they lose by less than 4 points.
Once you have found the right betting provider and deposited money, there is usually a bonus on the deposited amount. Then you can already place your first bets. But before it comes to that, you should have a look at the website. The offer of the betting providers does not only refer to bets, but also to sports news as well as tips and tricks for successful bets. This information should definitely be read in peace, then you can make the first bet targeted. This step reveals how extensive the bookmakers' platforms are. On average, betting providers manage around forty different sports. The offer ranges from football to Formula 1 and surfing. For each sport several countries, leagues and competitions have to be selected. In football, for example, there are European national leagues such as the German Bundesliga, the DFB Cup or the English Premier League, international competitions such as the Champions League and national championships, i.e. the European Championship and the World Cup. This exists for women and men as well as for almost all countries in the world. So there are numerous possibilities at games, races or competitions on which you can place bets.
Oftentimes you’ll see a point spread that has a half-point added to the number. Of course, there’s no such thing as half a point in a football game, so why do we so often see point spreads with a (.5) attached to the score? Sportsbooks do this to make sure there isn’t a chance of a push.  Let’s take another look at our game from above with the half point added.
Reading sports betting lines becomes easier with practice and experience with different sporting events. What looks like a jumble of letters and numbers actually gives a lot of information in a tiny amount of space. Different sports have different types of wagers available, such as the run line in baseball or the puck line in hockey, both of which replace the money line found in our football example. The more experience you have watching and gambling on different sports, the faster you’ll be able to read betting lines.
For the purposes of a halftime bet, the game essentially restarts at 0 to 0. According to the halftime spread, the Arizona Cardinals are expected to be outscored by the St. Louis Rams by 3 points throughout the entire 2nd half. A halftime bet of $110 dollars on the Arizona Cardinals would lead to a profit of $100, because, not only did the Cardinals beat the spread, they won the game outright. These bets are taken during halftime, leaving a small window for the bets to be placed. You can track halftime odds easily using our Sportsbook Insider live odds software.
If you wanted to place a $10 wager on the USA at 2.40 you would simply need to multiply your $10 wager by the 2.40 odds (10 x 2.40) to find out that the payout is $24. It is important to realize that with decimal style odds it includes the amount you wagered, so to find out profits you would need to subtract your wager ($24 – $10) to find out your potential payout is $14 in profits.
The 3-digit numbers to the far right are the listed prices for these bets.  This is also called the odds, vig, or juice.  An easy way to think of it is the amount you must risk to win $100 on this wager.  In our example, -110 means you must risk $110 if you want to win $100.  -110 is pretty standard, but you will find different options.  We will cover those in more depth when we talk about money lines.  The price of the bet has no impact on which team is favored.  Only the plus or minus on the point spread matters.  This is handled differently when you bet strictly on the moneyline.

Although the examples from above are in $100 increments, you don’t actually have to bet those exact amounts. That’s just how the odds are set up so that everyone is on the same page. With a quick glance at the numbers, you can tell who is the favorite, who is the underdog and what type of payout you can expect on each. You’re free to bet $5, $500 or whatever amount fits your budget. If you want to find out the specific betting limits for each option, browse through the betting sites rating guide in order to find the sportsbook that better fits your minimum and maximum limits.
For all the talk of new forms of wagering, the good old point spread remains the bet of choice for most NFL fans. Also known as the line or spread, the myth is that Las Vegas sets the point spread as its predicted margin of victory for one team. In reality, it's a number chosen by oddsmakers that will encourage an equal number of people to wager on the underdog as on the favorite. The negative value (-3.5) indicates that team is favored by 3.5 points. The positive value (+3.5) indicates that team is the underdog by 3.5 points. Betting on the favorite means the team must win by at least four points to cover the point spread. The underdog team can lose by three points and still cover the spread. You will also notice a moneyline value associated with the point spread (such as -3.5, -115). This indicates how much you must risk in order to book the bet (also known as the vig or juice). It means you have to risk $115 to win $100. The underdog may see a value such as +3.5, +105. This means you risk $100 to win $105 if your team covers the spread. The spread is not a static number, so you will notice line moves during the week. Team A may be favored by 3 points on Tuesday and by 4.5 points on Friday. This indicates more people are betting on them, so Las Vegas increases the underdog value hoping to encourage more wagers on the underdog.
As you can see above, the combined score for Superbowl XLV was 56, and since this line was offered at reduced juice, a wager on the over at 44.5 of only $105 would yield a profit of $100. This line closed at a high of 46 points at some books, demonstrating how the public, who tend to show a proclivity for high scoring games, can increase an O/U line.
One of the first rules of gambling is that nothing is ever certain. There's one thing that's almost certain though; you will make mistakes as a beginner. This is nothing to worry about, and in fact making mistakes is an important part of the learning process. That doesn't mean you need to make unnecessary ones though. There are a few mistakes that are routinely made by beginners, and it pays to be aware of these.
Over/Under means the odds-makers picked the most likely total combined score of both teams. For example in an NFL game with the Jaguars vs Dallas the over/under is 37. You can either bet on either “over” or “under”. Over, is if the two scores added up at the end, total to over 37. Under is if when you add them together, they’re less than 37. If the total is 37, it’s a tie, or “push” again.
