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.
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.
Futures betting also is offered on the major events in horse racing, such as the Kentucky Derby and Breeders' Cup. In horse racing futures, if your horse does not start the race due to injury or any other reason, you lose the bet -- there are no refunds. On the other hand, the odds on your horse racing futures bet also are "locked in," regardless of the horse's odds on race day.
Oddsmakers do more than pick the winners and losers of each game. They weigh myriad factors to determine which team is favored by how many points. They set an early point spread on each game, then adjust it up or down based on betting patterns. If the Dallas Cowboys are 6-point favorites over the New York Giants, they must win by seven or more points to pay off winning bets. If you wagered on the Giants, you win your bet if New York either beats Dallas outright or loses by five points or fewer.
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.
When betting on the favorite, simply divide the negative moneyline by 100 to get a decimal. If you were planning to bet on the Celtics in the above example, this would give you 2.40 (ignore the negative). Now all you have to do is divide your stake by that number in order to see what your potential payouts would be. Let's say you wanted to stake $650. When you divide that number by 2.40, you'd see that your potential payout is $270.83.

Having set the point spread, this is the point where the gambling public can influence the line. You might have noticed that a line five days before a game might look very different to the line an hour before the kickoff. Barring some major line-up changes due to injuries or suspensions, the line will most likely be moved by weight of money. If the majority of money is coming in on one side of the point spread, the book will move the line to make the bet a little less attractive, which will help them level the book up somewhat.
The way the sportsbook does this is by putting out a betting line that is based on how many points they think the better team is going to win by. This is a lot like how our older siblings would "spot us" a few points when we played each other in basketball as kids. For example, let's say that Florida Gators are playing the Arkansas Razorbacks. Let's also say that Florida is the better team and the sportsbook thinks they are going to win the game by seven points. They can't just let everyone bet evenly, or everyone would bet Florida and clean them out. Enter the point spread. The sportsbook would set the point spread on this game at -7 for Florida to win. The negative sign before the number signifies that this team is the favorite to win. This means that if you want to bet on Florida, they have to win by more than 7 points for you to win your bet.

The punter usually receives all dividends and other corporate adjustments in the financing charge each night. For example, suppose Lloyds Bank goes ex-dividend with dividend of 23.5p. The bettor receives that amount. The exact amount received varies depending on the rules and policies of the spread betting company, and the taxes that are normally charged in the home tax country of the shares.

"Half time/Full time" is where it is possible to bet on the result in half time as well as the final outcome of an event. For example, if at half time the score is 45-45 and the match ends 103-101, the winning outcome is Tie / Away Team (the team scoring 103). The bet is void if the regular time of the match is played in a different time format than those listed in the bet . For example, in baseball, half time is defined as the first 5 innings of a game.

The term moneyline is actually somewhat misused in sports betting as it really just means a type of odds format. Technically, it is a way to represent the odds/payouts for a win bet, but we’re not going to split hairs. What we’d like to point out is that the odds on each participant in a sporting contest can be listed in one of three different formats.
There's another reason to bet the underdogs on the moneyline as well. If your handicapping has made you feel very strongly that a poor team is due for a big win then the moneyline allows you to profit much more handsomely from your conclusion than a point spread bet does. The moneyline, then, is a powerful situational tool for people who closely follow the NBA.
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.

Before actually betting or creating your draft for your fantasy football team, it’s best to take time to study the methods well and find a credible website that would give you the best forecast for NCAA Football Odds. The key to a higher probability in winning is to be able to use all the odds in correlation to each other. Once you understand how NCAA Football Odds computed, you’re on the right track to achieving your goal.
Earlier, we explained how the implied probability of -240 is 70.59% and how the implied probability of +210 is 32.36%. Notice these two probabilities total 102.95%. The extra 2.95% is the bookmaker's advantage. It's called vig, and it's basically a commission that they charge customers for placing wagers. By removing the vig, you can see what the fair odds on the game would be.
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.
There are four elements to the moneyline bet that you can see here. The first column is just an identifier of which bet is which for the sportsbook. When you place your bets, you can tell the sportsbook you want to bet on the Eagles to win or that you want to take bet 055. This number has nothing to do with the actual game and is just a code for the sportsbook to keep their bets organized.
In this example, we have a favorite to win, and an underdog. The Packers are the favorites, and that is shown by the (–) value in front of the 6. Underdogs are represented by the (+) value.  The 6 point value is how many points either team could win, or lose by. If you think the Packers will win by MORE than 6 points, then you’d bet on the favorite in this case, meaning that the Packers have to win by 7 or more points in order for you to win your bet.
