You may have noticed that we said earlier that it’s the amount of money bet on each side that is important to the sportsbook and not the number of bets. This is an important distinction to understand. If 100 people bet $10 on Team A, and then one person bets $10,000 on Team B, the line is going to shift to attract action onto Team A. Even though more people bet on Team A, more actual money came in on Team B.
Let's use this formula to calculate the implied probability of the Celtics winning their game against the Grizzlies. We know the odds are -240, which means we'd have to risk $240 for a total potential return of $340 (the initial stake plus the $100 winnings). So the calculation here is $240 divided by $340. This gives us an implied probability of 0.7059.
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.
Without a points handicap, it would not make sense to pay both sides of a wager the same amount when it's clear that not all teams are on equal footing. In fact, it is entirely possible for a team to lose the game in real-life but still win a bet if they only lose by less than a set number of points. Vice versa, a team can win a game, but lose the wager if they do not win by more points than what was predicted.
It is a pretty simple concept once you get the hang of it, and you will also start to see profitable opportunities in football and hoops where wagering on the moneyline makes more sense than betting the point spread. If you really like an 8-point underdog in the NFL and think they will win, you can take the 8 points and hope they cover the spread. Or you can check out the moneyline option where they might be +280 and make more money betting them to win ($280) than on the point spread ($100).
Something that all of our pro bettors on staff preach is that there is no reason to make anything more complicated than it needs to be. Specifically, they are referring to the awful trend of aspiring sports bettors thinking that you must make more complex bets in order to make a living betting sports. The reason we say it’s an awful trend is because this couldn’t be further from the truth.

The point spread is basically used to create a 50/50 betting proposition. In this example, the Celtics are theoretically just as likely to win by six points or more as the Grizzlies are to lose by less than six points. This is reflected in the odds, which are typically -110 on both sides of the wager. You have to risk $110 for the chance of winning $100.

Anybody who wagers on the 49ers would need them to win by 7 points or more for a winning bet. Those betting on the Rams (+6.5) would need them to lose by 6 points or less (or win) for a winning wager. It's also worth mentioning that a half point is used in many point spreads (such as the -6.5/+6.5) to prevent pushes because no team can score half a point.
82 games per year means a lot of opportunities to wager on your favorite teams and Sportsbetting.ag sees that opportunity and gives you what you want to bet on. Sometimes this means having spreads for big games a day or two in advance, especially if both teams are off the day before the big matchup. They take care of their NBA bettors... give them a shot.
Had you initially bet $100 on the Mavericks, you would walk away with a profit of $90.91. Now, if you bet on the Mavericks, you will see a profit of only $76.92. On the other side of the bet, an earlier bet on the Magic would have paid you $105. Now that same $100 bet will get you $125 if the Magic win the game. Ideally, this will entice more people to bet on the Magic and the action on the Mavericks to slow down.

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]
If you want to bet on football, then you have plenty of options. There are not only lots of games you can bet on, there are also lots of different types of wagers you can place. Point spreads and totals are the most popular types, by quite a distance, and many football bettors stick solely to those. This isn't really the ideal approach, as some of the other wagers can be very useful in the right circumstances.
A lot of people who are new to online betting aren’t aware of prop bets, because a lot of brick-and-mortar sportsbooks just don’t have the resources to allow them. These bets are a great way for you to make some extra money off of predictions that might not have a direct outcome on the winner of the game. For example, let’s say you think that the Warriors are going to shoot lights out from the field, but you think for some reason they aren’t going to get a lot of looks and are going to lose the game. Your only option without prop bets would be to bet on the team they are playing against, but that might not be a great value bet.

The secret to winning sports bets is finding value and picking winners. There is absolutely zero correlation between the complexity of a bet and how likely you are to win. In fact, you could say that there is a negative correlation because a lot of bettors don’t fully understand the complex bets they are making, meaning they are more likely to make mistakes and incorrectly assess value.

Betting on sporting events has long been the most popular form of spread betting. Whilst most bets the casino offers to players have a built in house edge, betting on the spread offers an opportunity for the astute gambler. When a casino accepts a spread bet, it gives the player the odds of 10 to 11, or -110. That means that for every 11 dollars the player wagers, the player will win 10, slightly lower than an even money bet. If team A is playing team B, the casino is not concerned with who wins the game; they are only concerned with taking an equal amount of money of both sides. For example, if one player takes team A and the other takes team B and each wager $110 to win $100, it doesn’t matter what team wins; the casino makes money. They take $100 of the $110 from the losing bet and pay the winner, keeping the extra $10 for themselves. This is the house edge. The goal of the casino is to set a line that encourages an equal amount of action on both sides, thereby guaranteeing a profit. This also explains how money can be made by the astute gambler. If casinos set lines to encourage an equal amount of money on both sides, it sets them based on the public perception of the team, not necessarily the real strength of the teams. Many things can affect public perception, which moves the line away from what the real line should be. This gap between the Vegas line, the real line, and differences between other sports books betting lines and spreads is where value can be found.
Remember, these calculations are for your profit. Profit is different than the total money returned that you will get from the sportsbook. If you correctly bet the Falcons to win, the sportsbook will return you $340. This will be your $240 in profit as well as your $100 bet that you made. Make sure that you pay attention to this when working with these numbers because we see people get confused all the time as different sportsbooks will give you different numbers.
This arrangement tells us a lot: which team is home (listed on bottom, in this case the Seattle Seahawks), which team is the underdog (listed with a plus sign next to their name, in this case the New England Patriots), we know which team is the favorite (listed with a minus sign next to their name, in this case the Seattle Seahawks), and we know the point spread (2.5 points).

A point spread (or line) is a tool used by sportsbooks to attract wagers on both sides of a game. The line is most commonly used in football and basketball games. Because it’s rare for two teams in a pro sports game to be completely evenly-matched, one team will have an advantage, another will be seen as the underdog. The point spread is the handicap offered to the underdog to level the playing field, so to speak.
The number that comes after the plus or minus sign is how significant of a favorite or underdog the teams are, regarding points. In the first game, the Bengals are a 1.5 point underdog. This means that the sportsbook thinks the Bengals are going to lose the game by 1.5 points. This means, by default, that the Chiefs are a 1.5 point favorite. This means the sportsbook thinks the Chiefs are going to win the game by 1.5 points.
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.
The Patriots are set to take on the Rams in the greatest show on turf and money has been flowing into both sides of the Super Bowl 53 point spread. The Patriots are -3 for SB LIII according to most legal online sportsbooks but some have them listed only at -2.5. The Rams and Patriots are both offensive minded, and capable of scoring quickly; therefore, the winner will likely be whoever scores last in the game (-180). There is still no discussion of whether the roof will be open or closed at Mercedes-Benz Stadium in Atlanta, so weather may or may not play a factor here. Either way, make sure to get in your bet on the spread for Super Bowl 53, whether you choose the Patriots or Rams, before the 6:30 EST kickoff on Sunday, February 3rd.

It is a very good idea to shop around to find the best line when you are betting on sports. Books may offer slightly different lines, and you might be able to gain a point or half a point in your favor on certain markets. Consider an NBA game between the Heat and the Lakers – one firm has the Heat 9.5 point favorites and another have the Heat as 8.5 point favorites. You back the Heat with the second firm and they win by exactly nine points. Here you’ve gone from a loss to a win simply by shopping around, and in the long run this will make a big difference to your bottom line.


As we mentioned, moneyline/win bets take into account who the favorites and who the underdogs are and will pay out winning bets accordingly. Here’s a quick example that will make this clear. Imagine that Mike Tyson (one of the greatest boxers of all time) is going to fight against an 80-year-old man. If the sportsbook let you bet on either side of the fight and paid you the same, would that be fair?
Of course, it wouldn’t be. Everyone would bet on Mike Tyson, and the sportsbook would lose all of their money and close the next day. So what the sportsbooks do is they assess who is the favorite and who is the underdog and assign a value to how much in each direction they think they are. Let’s look at what the odds might look like for our fictitious fight and break down what everything means.

Placing a point spread bet means gambling on how much a team will win or lose by. In our above example, the Cowboys are the favorite. How do we know that? The minus symbol in front of the point spread indicates that the bookmaker thinks the final score will have Dallas winning by 7.5 points or more. The underdog, in our example that’s the New York Giants, will always be indicated with a plus sign. If you wager on the Cowboys on the point spread, America’s Team will have to win by at least 8 points for your wager to pay off. Should the Cowboys win by less than 8 points, your bet is lost.
In an effort to have equal money on both sides of a wager, the sportsbook operator will move the point spread to attract money on the side that customers aren’t betting on. The odds for a point spread might change before the actual point spread. There are certain point spread numbers, like 3 and 7 in football, the sportsbook operators would like to avoid moving away from since they final score margin falls on these two numbers most often.
