Betting “against the spread” (ATS) just means you’re betting on the point spread in a particular matchup as opposed to the moneyline, or some other type of wager. Bettors often use a team’s ATS record to gauge its performance against the spread. For example, the New England Patriots were 11-5 ATS in the 2017 regular season, meaning they covered the posted point spread 11 times, and failed to cover five times.
The point spread will list one team in the negative and the other in the positive. (Unless neither team is favored, then they will be listed as EVEN or PICK). The club posted in the negative with a minus sign is favored and so the bookies take points away from them, which means that team must win by at least a certain number of points to cover the spread. The underdog will have a plus sign and will cover if they win outright or lose by less than the posted number.
For example: New England –2.5 (–110) or Philadelphia +2.5 (–110) means you’d wager $110 for the chance to win an additional $100 if you bet on the point spread. Depending on which side is receiving the most action, a sportsbook will often move the line up or down in order to incentivize betting on the less popular side. Injuries or unforeseen changes can also impact a point spread gambling line. Point spreads are often listed with a half-point (ex: 2.5) in order to prevent the final margin from landing exactly on the point spread (ex: 10-point spread, final score of 20–10). A “push” or “tie” usually goes to the house or sportsbook, unless another arrangement has been agreed upon beforehand.
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%.
For example, a negative value (-11.5) next to a team indicates that they are favored by that many points. So you must deduct 11.5 points from their score to determine if they won the game or not. On the other hand, a positive value on the same game (+11.5) means the underdog starts with an 11.5-point lead before the game even begins. In NFL betting, the favorite must win by 12 points or more to cover the NFL spread. The underdog is able to lose by 11 points and still cover the spread.
But what if the basement-dweller team was spotted 24 points? That's the concept behind the point spread. When two teams meet on the football field or a basketball court, one team is typically better than the other. If all bettors had to do was to pick the winning team, everybody would simply wager on the best team and collect their money. Gambling institutions, sportsbooks, and bookies would soon go broke. 

If you place wagers on US sports, then chances are high that you've heard of point spreads. Here's how they work; if a game has Patriots -9.0 and Vikings +9.0, the Patriots are 9.0 point favorites and the Vikings are 9.0 point underdogs. Unless otherwise stated, no matter which team you bet on, you'll be required to risk $1.10 for each $1.00 you want to win. For Patriots bettors to prevail, they need their team to win by 10 or more points. A 9-point Patriot victory would be a push (a tie). For Vikings bettors to take home the victory, they need to either win the game or lose by less than 9 points.

The busiest season of the year in the sports book is upon us. Betting on football makes up more than half the money wagered on sports every year in Nevada. The Nevada Gaming Commission doesn’t break down the wager money by the level of football. However, it’s widely discussed that there’s more money wagered on the NFL than college football. Canadian and Arena football are really just available to pass the time for fans until the fall.
The concept of betting on totals, or Over/Under (O/U), is quite simplistic. The bettor wagers on whether the TOTAL points scored in a game will fall over or under a pre-determined number set by the sportsbook. Much like the point spread, game totals can be swayed by public opinion. The example below, from the SI Archive, shows the opening totals line for Superbowl XLV:
If you're seeing 15 or 25 instead of 15/1 or 25/1, you're seeing a decimal form of odds, as opposed to fractional. Multiplying your stake by decimal odds gives your total return, not your profit(which is total return -stake). To get to fractional from decimal, add 1. So 3/1 fractional = 4 decimal (just 4). 4/6 frac = (4/6+1) dec = 10/6 = 5/3, or 1.666, which is rounded to 1.67 by bookies. To go from decimal to fractional, subtract 1(which makes sense from profit = total return - stake) So 15 dec = 14/1 frac. 2.33... dec = 1.33/1, or 133/100.
As already mentioned, there have been sports bets since the first sports events. There is evidence that bets were placed on the first Olympic Games in ancient Greece. The bet was placed on the winner of a race or the winner in wrestling. The more matches there were to the games, the more bets there were. The Romans made bets on almost everything that was possible. Among them also the bloody gladiator fights and chariot races. From the very beginning, fraud and manipulation were a means of winning a competition. The Roman Emperor Nero even bribed so much at the Olympic Games in his own country that he won in six different disciplines. One of them was the car race and that although he fell off the car, which normally leads to disqualification. The Olympic Games were then discontinued, but not the sports betting. In the last century there was again a time when sport, especially boxing and horse racing, fell into the hands of criminal gangs. The image of sports betting had to suffer a lot from this bad influence, also because Hollywood used the topic as the basis for many films, as a result of which perception in society drifted further into the negative.

Often big games will have "proposition" bets on things not directly related to the final score of the game. These are usually abbreviated to "prop" bets. For example, in football whether or not the first score will be a touchdown. In baseball whether a run will be scored in the first inning. In hockey/soccer, whether anybody will score a hat trick. The odds on these are expressed like point spread bets. For example, as I write this the Golden Nugget has the following proposition bet on Super Bowl 49:
Total – also widely referred to as the over/under is the predicted number of points oddsmakers believe will be scored in the game by both teams combined. The concept is simple – handicap how each team stacks up against each other on offense and defense and predict whether there will lots of scoring or not much. In totals betting, you are predicting whether the combined total score will be more than or less than the total.
If you aspire to become an avid bettor and are serious about learning the trade, the first thing I recommend doing is to come up with several angles and legitimate reasons why betting on a specific team is going to make you money. I understand that angles and reasoning can only take you so far before what happens on the court or field is out of your control but playing the angles is a key part of sports betting that isn't going away any time soon. One of the better angles I look to play is a bet called the First Half Bet. Read More >>
If you've ever made a full-game bet that was completely toast by half time, I will assume you know all about the half time bet. If you are one of the lucky few who don't know what that feeling is like, a half time bet allows you to wager on the outcome of the second half on any particular game - regardless of what happened in the first half. If you look hard enough and focus in on one or two games, you can often find a line that offers more value than you would normally find on a full game line because the line is soft. Read More >>

Have you ever skimmed through the baseball or hockey results and thought to yourself "wow the 'over' was the play of the night since it hit in 10 games?" If you have and are kicking yourself for not playing every one of those games, this Grand Salami bet is the bet for you. The Grand Salami is not a massive delicatessen but rather a bet in which you must correctly guess the 'over/under' of the total number of runs or goals produced in every single game combined on any one given day.

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.

But Bevin, a Republican, was one of three governors who signed a legal brief in the Supreme Court case that urged the justices to overturn the federal ban. The brief, written by West Virginia Attorney General Patrick Morrisey, is largely concerned with the federal government commandeering states’ rights and not about people’s ability to wager on sports.
NFL moneyline betting continues to gain popularity as many begin to understand the value of moneyline bets, especially in betting the underdogs. In this type of bet, there is no spread to beat, your team needs only to win the game “straight up” (SU), and there is no requirement for how many points they need to win by. The juice is the only number you really have to pay attention to with moneyline, where the negative value indicates the favorite (-140) and a positive one means underdog (+120).
