A spread is a range of outcomes and the bet is whether the outcome will be above or below the spread. Spread betting has been a major growth market in the UK in recent years, with the number of gamblers heading towards one million.[1] Financial spread betting (see below) can carry a high level of risk if there is no "stop".[2] In the UK, spread betting is regulated by the Financial Conduct Authority rather than the Gambling Commission.[3]
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.
The sportsbook is not going to have props conveniently labeled as “skilled NBA props” and “gamble, gamble props,” so it’s up to you to use your common sense to decide which bets you should be getting involved with and which you should be avoiding. Remember, unskilled entertainment prop bets are not bad as long as you know that they can’t be beaten long-term unless through sheer dumb luck.
Is there value there? Yes. Are you going to make money off that bet? Well, it depends. If you’re only able to make a bet like this once, then you’re most likely going to lose. In order to realize that value, you’ll need to be in a lot of similar opportunities. If you have a very long-term betting strategy, then you can probably get away with making this bet. But if you’re looking for some more regular profit, you might want to steer clear of this. The odds say that the team is only going to win the game a little under 3 times for every 100 times they play. There is value there, but it depends on your betting strategy if you want to make that bet.

The negative (-) sign indicates that the Cowboys are the favorites, while the positive (+) sign indicates that the New York Giants are the underdogs. With the spread set at 2.5 points, a bet on the Cowboys would mean that they would have to win by more than 2.5 points (3 or more) in order for you to win that bet. A bet on New York would mean that the Giants would have to either lose by 2.5 or less points (2 or less) or win the game outright in order for your bet to win.
When betting on the underdog, the first step is the same. Divide the positive moneyline by 100, which in the case of the Grizzlies in the above example would give you 2.10. Then, multiply your stake by that number to get your potential winnings. $450 multiplied by 2.10 is $945. Essentially, this means if you risked $450 on the Grizzlies, you would stand to win $945.
Shopping betting lines is one of the most important things you can do when betting point spreads in basketball. While the majority of sportsbooks will have the same line, it's fairly common that you can find lines that are a half or full point different. This can have a huge impact on your bottom line. If you don't think a half point or one full point makes that big of a difference, just ask anyone who has bet sports for a while. They will inform you that getting an extra half point is like winning the sports betting lottery.
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.
