# The reason why you will typically see a (-110) line next to a point spread is simple. This is the commision in which the sportsbooks charge for you to place your wager. This is how the casino makes their money. Think of it as a commission. You make a bet, they charge 10% for you to do so. Bookmakers call this “Vigorous or Vig” it’s also known as the “Joice”

If you've never set foot in an actual sportsbook before or logged into an online sportsbook, the chances of you getting overwhelmed when you actually do is very high. In an actual Las Vegas sportsbook, there is typically a lot of commotion and the odds and lines are displayed on a massive digital board for everyone to see. When a novice sports bettor looks at the massive digital signage, they will see a bunch of numbers, both positive and negative, some two digits, some three digits. They also won't have a clue what any of it means. The same can be said for the online sportsbooks. It looks like a massive spreadsheet with negative and positive numbers beside each teams' name.

_{As you may already be assuming, adjustments are made if you want to bet on the Razorbacks. The point spread for the Razorbacks would be set at +7. It will always be the exact opposite of the other team. As the negative sign represents the favorite, the plus sign here represents the underdog. If you were to bet on the Razorbacks, they can actually still lose, and you win your bet. }

Almost all point spread wagers are paid out at moneyline odds of -110. This is almost even money minus the percentage that is taken for the sportsbook's cut known as the vig. Sometimes you will see a bit of variation in the payout odds, but for the most part, you should expect to see -110. If you don't see the payout numbers posted but just the point spread, you can most likely assume that you are to interpret that as being paid out at -110. If you're ever curious, though, just ask for clarification or look at your betting slip.

`Above, you can see several numbers to the right of both teams. These all represent the different lines that are available on the San Francisco vs. Los Angeles game. The first set of numbers for both teams is the point spread, the second set is the moneyline, and the third set is the over/under (a.k.a. totals). We'll explain each of these lines more in-depth below.`

Overtime and the shoot-out does count for NHL point-spread results in Ontario. Whenever you see a game -0.5 essentially both teams have a spread of -0.5 and your team has to win the game for you to win the bet. Lately there have been more -1.0 / +1.0 NHL spreads in Ontario. If you choose the -1.0 spread and the game goes to overtime you cannot win the bet. You can only push the bet if your team wins in overtime or the shoot-out. Conversely, if you choose the +1.0 spread and the game goes to overtime you cannot lose the bet but will push the bet if your team loses in overtime or the shoot-out.

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.

*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.*

__Point spreads are more common in the United States, but you can see them throughout the world. A point spread, in theory, is the sportsbooks attempt to create a "level playing field." Let's look at an exaggerated example that will make this clearer. Let's say the New England Patriots are playing a game against a junior varsity high school football team. They're also using deflated footballs, and the Patriots get to see the high school team's playbook before the game. If a sportsbook were to allow you to bet on which team would win, everyone would bet on the Patriots as they would probably annihilate this other team.__

`If the team is an underdog, then the moneyline number represents exactly how much you would get paid in profit for a correct pick. So if we were to bet $100 on the Boston Celtics and won, we would get paid $145 in profit. Seems easy enough, but you may already be asking what happens if you don’t want to bet in increments of $100. This is totally fine and still straight forward to figure out.`

`If you bet on sporting events, you must be able to read odds and understand what they mean. Furthermore, you need to quickly calculate the potential winnings for different bets, especially if the odds are changing while the event unfolds. Odds tell you the likelihood that an event will occur (a team wins, a boxer makes it a certain round) and how much will be paid out if you win. There are, however, multiple ways to convey this information.`

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.
