This used to be impossible or extremely time-consuming when only land based sportsbooks and casinos existed. You would have to drive hundreds of miles if you wanted to get to another casino and then hope they still had the different line. This would cost you travel money as well as time. Online sportsbooks make this extremely easy now. You can check several sportsbooks lines on a game within a matter of seconds or minutes. It doesn't cost you any additional money, just a few minutes of your time and can have a huge impact on the outcome of your bets.
If bettors were quick to jump on the Atlanta line at +4.5 when it first came out, they would have a distinct advantage over those who waited closer to kick off and were stuck with +2.5. The opposite holds true for Carolina. Bettors that were quick to pull the trigger are now laying two more points than they would if they were patient and saw the line movement before making their move.
Let’s start with the basics: what do sports bettors mean when they talk about a ‘line?’ The word line, in the language of a sportsbook, can refer to either the odds and/or a point spread in any sports contest. Let’s take a look at an imaginary line the way you’d read it off the board sitting in a Vegas sports betting lounge or on the screen at your online book. Let’s imagine a game between the New York Giants and the Dallas Cowboys. Your book’s NFL betting line might look something like this:
An over-under bet in basketball is a wager on whether the total score for the game from both teams will be above or below a certain threshold. This is a great bet to utilize when you think that a game will be defense heavy and both teams will be shooting cold, or when you think that it’s going to be a barn burner with both teams shooting lights out.

For example, if you’re betting on teams A, B, and C to win outright, you’ll have two round robin options available. Your By 2’s option includes all possible 2-team parlays for these three wagers (A+B, B+C, and A+C). And your By 3’s option includes all possible 3-team parlays on these 3 wagers (A+B+C). If you wager $30 on the By 2’s option, that money will be split evenly among the 2-team parlays ($10 on each of the 3 wagers).
On the other hand, underdog moneylines can be lucrative wagering opportunities. Upsets happen more often than some of us think and moneyline betting is a great way to take advantage. For example, for a moneyline wager of +250, a bettor will only need to win about 28% of the time to break even and for a +300 wager the bettor would only need to win 25% of the time to break even. If you can spot upsets even decently well, moneyline wagers on underdogs can be profitable bets.
Since betting on point spreads in the NFL is the most popular bet that people make, it is probably pretty important that you know what you are doing. The point spreads in the NFL are always alot closer then college football because you are dealing with the best of the best. You will almost never see a team favored by more then two touchdowns in the NFL, and most of the NFL point spreads are less then one touchdown. So, here is are best try at helping you understand how to read point spreads in NFL games.
Some professional or seasoned bettors only use the point spread bets and are wildly successful. Their success comes from making correct picks, not from overcomplicating the situation. We're going to walk you through the basics, and the mechanics of a basketball point spread bet, discuss the popularity and benefits, and offer some tips and strategies to help get you moving in the right direction towards profitability with these bet types.
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.
In this game between the Boston Celtics and the Dallas Mavericks, you’re given the option to bet on either team. Going into this game, you know that Mavericks are favored to win. If the sportsbook didn’t adjust something (the line or the payouts), everyone would bet on the Mavericks, and no bets would come in on the Celtics. If the Mavericks were to win, the sportsbook would be out of money and have to shut their doors.

You don’t have layers of complexity to fight through to see if your prediction is a positive expected value move (one that is going to make you money). With some simple mathematical calculations, you can figure out whether or not there is value in a bet. Even if you don’t like math and would prefer not to use it when assessing value and making your picks, it’s still much easier to “eyeball” value with moneyline bets because of the simplicity.

Many novice bettors fail to understand the impact of home advantage when wagering on sport events. When looking at the board for potential wagers, these bettors tend to get excited and bet on lots of superior teams favored on the road against weaker opponents. The betting market is so much more advanced than this, and for the most part point spreads are always going to be 50/50 propositions.
This means that the people betting the big bucks are going to end up shifting the line considerably. A lot of times, you will see a moneyline released, and then it will quickly shift. Usually, this is a skilled big bettor taking advantage of what they think is an opportunity. Ideally, you’ll want to jump on bets before these skilled bettors get ahold of it.
A common mistake that new bettors will do is to bet every single game. Unfortunately, this is not a winning strategy no matter how sharp you are. Stick to betting the games where you actually see value. Here's what we mean by value. Let's say in our earlier example that you agree with the sportsbook that the Florida Gators should win the game by seven. You should not bet this game then no matter what if the line is -7. If you're right, the best you can do is tie on your bet. When you pick a side, you're basically going to be guessing and flipping a coin. Theoretically, you'll win as many times as you lose, but you'll be paying the house percentage every single bet and slowly bleeding your money and profits away.
This is a very common occurrence in sports betting and sportsbooks have the full right to shift the spread or odds for any given match prior to it starting. Many factors can influence a change of the spread such as injuries, the number of bets coming in for either team or the weather, to name a few. Depending on the timing of placing the bet, the bettor can also have an advantage or a disadvantage depending on which way the spread has shifted.
