**Let’s say that people think the Mavericks are going to crush the Magic, and the money starts to pour in on the Mavs. Obviously, the sportsbook likes seeing a lot of bets come in, but they need them to come in evenly. So, to slow down the money coming in on the Mavericks and entice people to bet on the Magic, they will shift both lines. The new line might look something like this:**

With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.

*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.*

Moneylines have a tendency to move quite a bit in both directions leading up to a game, match, or fight. It’s a delicate dance that you’re going to have to master if you want to find value and push your edges to the max. Sports betting is a profit source that is all about small edges. Finding and being able to capitalize on these small edges is the key to being profitable long-term.

When unforeseen events occur such as weather, power outages, or any other unanticipated event once the game has started, many people wonder how that will affect the wager. If an event has not started, all wagers should have no action and be refunded. But if the event has started and is interrupted and not completed it gets a little more complicated. The following will examine the special rules for each sport and give you a better idea of what to expect should the event not be completed on the same night. Always check with your book to know any special rules that may apply but according to the letter of the law: the following is how each event should be interpreted.

When the point spread was invented in Chicago by Charles McNeil the money line took a backseat. When two unevenly matched teams played, the playing field was leveled by having the favorite give points (for example Chicago Bears –7) while the underdog got points (Minnesota Vikings +7). No matter which team the bettor took the bettor would always risk $110 to win $100. The extra $10 needed to win $100 is called the juice or the vig, it is basically the house’s or the bookie’s take. It’s 10-percent of the bet so it would take $33 to return $30 and $440 to return $400 etc. (winning bettors get the vig back).

*The -110 on either side is like paying a tax or commission to the sportsbook. Bettors would pay 10 percent (aka juice) to the sportsbook, which is essentially a fee for brokering the wager. So, the -110 indicates that a bettor must risk $110 to win $100. Some sportsbooks will even reduce the juice for you which means you can earn the same $100 payout but risk less money to do it.*

**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.**

_{You can also bet straight winners and losers -- with no point spreads involved -- with money line wagers. When there is a minus number you bet that amount to win $100 in profit. When there is a plus number, that is your winning profit for every $100 wagered. So if the Cowboys have a money line of -250, you would have to bet $250 on them to win $100 in profit on any Dallas victory. If the Giants had a money line of +150, you would win $150 in profit with a winning $100 bet. If a money line is posted as even, you would win a $100 profit on a $100 winning bet. }

_{Baseball, soccer, and ice hockey are mostly moneyline betting, since these sports do not have point spreads moneylines are the default way of wagering. Football and basketball do have moneylines in addition to point spreads. In recent years, football moneylines have become extremely popular among sports bettors. Moneyline betting is based on the amount bet per $100. Let’s look at look an example of a baseball moneyline: }

__Futures are wagers on long term events which generally won’t have a result for many weeks or even months. The most popular type of futureswager is placed on the outright market which basically means, who will win a league’s championship? FanDuel also offer many other markets outside of the championship, usually including divisional and conference wagering. The odds on futures change as the event gets closer and more is known about the teams. Very often odds will also be updated as the tournament or league progresses.__

_{Ideally, the lines I release will balance the action equally, so that the winners get paid out from the pockets of the losers and we take the vigorish. That’s an ideal that rarely happens – especially in sports without a pointspread, like NASCAR and golf. If Team A is getting too much action, I’ll move the line toward Team B to try to achieve that balance. My personal preference is to tweak the vig from –110 to –105 or +100 before taking the bigger step of moving the spread a half-point or more. }

A money line, used in baseball and hockey, takes the place of a point spread. Money line betting is simply wagering on the contest based on a given price rather than a point spread. The team wagered on has to win the game outright, regardless of the score. The minus sign (e.g.-130) always indicates the favorite and the amount you must bet to win $100. The plus sign (e.g.+120) always indicates the underdog and the amount you win for every $100 bet. Using this example, therefore, you would bet $130 to win $100 on the favorite, while for the underdog you would bet $100 to win $120.

**When betting the point spread, there is almost always a winner and a loser. However, in some instances sportsbook decide to put out a whole number such as -3 for bettors to bet on. If the final score ends with a differential of three points - no matter who wins - the bet is considered a "push" and all money is refunded to both sides since neither team covered the spread.**

__In addition to the spread bet, a very common "side bet" on an event is the total (commonly called the over/under or O/U) bet. This is a bet on the total number of points scored by both teams. Suppose team A is playing team B and the total is set at 44.5 points. If the final score is team A 24, team B 17, the total is 41 and bettors who took the under will win. If the final score is team A 30, team B 31, the total is 61 and bettors who took the over will win. The total is popular because it allows gamblers to bet on their overall perception of the game (e.g., a high-scoring offensive show or a defensive battle) without needing to pick the actual winner.__

# Linemakers who work for the sportsbooks must put out lines that will entice the "favorite" bettors to lay the points and take the favorite or entice the underdog bettors to take the points with the underdog. Because each sportsbook is operated under their own rules, guidelines and stipulations, they are free to put out whatever line they feel is competitive and charge whatever vig they want to based on how much action that specific line is taking.

**All connotations related to the bet must be fully and unquestionably complied with for the bet to be deemed as winning, regardless of any possible conflict with the sport-specific rules, or with any potential interpretation based on previous or current presentation of offers related to events in that particular sport and the way these are normally presented in DraftKings Sportsbook. Bets will be settled as void should it still be impossible to determine a winning outcome.**

Why is this important? If you’re only looking for a fun sweat, it does not matter at all. But, if you’re looking to be a winner and making money long-term is important, then this becomes critical. For those of you profit-minded bettors, make sure that you are only betting on the prop bets that require quite a bit of skill. These bets will be the ones that your knowledge, research, and expertise will help you win over the long run.

^{Betting against the spread or ATS, as it's known in the sports betting industry, is among the toughest bets to turn a profit in over the long run. When looking at a team's record, the only thing that matters to them is winning the game outright and moving up in the regular-season standings. Teams like Golden State or the New England Patriots are generally always among the best teams in the league (straight up) but are typically a bad bet to make ATS. The reason for this is because the better the team is, the more public attention they draw and the higher the point spread is. Sportsbook know which teams the public darlings are and as such inflate the spreads in order to take advantage of how overvalued the public makes them. A team like the Patriots could go 14-2 every season but they could be a dismal 7-9 or 6-10 against the spread because they are laying more than 10 points in every game. }

**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.**

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.

In theory, sportsbooks don't care about the outcome of a game, although for those of you who bet on the Steelers (-5.5) last season versus the Chargers and saw a game winning TD returned by S Troy Palumalu as the game expired reversed, thus negating a seven point victory and putting the final at 11-10, you might think otherwise, but this is how it's supposed to be.

`For example, in a cricket match a sports spread betting firm may list the spread of a team’s predicted runs at 340 – 350. The gambler can elect to ‘buy’ at 350 if they think the team will score more than 350 runs in total, or sell at 340 if they think the team will score less than 340. If the gambler elects to buy at 350 and the team scores 400 runs in total, the gambler will have won 50 unit points multiplied by their initial stake. But if the team only scores 300 runs then the gambler will have lost 50 unit points multiplied by their initial stake.`
