Before we had the options of wagering on future bets, parlays, teasers, alternative lines, Asian lines, prop bets and each-way, there was one betting option that reigned supreme. It was the money line bet. From a non-gambling perspective, winning a game in any sports will make a team happy. However, depending on the score, that win may not please bettors. That’s because the point spread betting option has taken over as the popular option, leaving the money line far behind. If you are the kind of person who bets on your favorite team each and every game, this is the bet for you. There is nothing worse than watching your team win the game, but lose you money by not covering the point spread.
Let’s take a quick step back and talk about what the sportsbook’s goal is with any game they are offering action on. Ideally, the sportsbook wants to take the perfect amount of action (money bet) on each side of a game so that regardless of who wins, they make money. Their profit comes from taking a small percentage off of the top as a house fee for facilitating the action.
As an example, let’s consider a matchup between the Indianapolis Colts and the Cincinnati Bengals. In our scenario, the Bengals are the home team, which means they will be listed last and the Colts, as the visitors, will be on the odds slip first. If Indy’s rotation number is 101, then Cincy’s rotation mark would be 102. When you place a bet live at a Vegas sportsbook or over the phone, you would say the number of the team on which you want to wager and not the name.
Sportsbooks will use a variety of methods to set their line on a game. Some firms will use computer simulations, some will use a form of power ratings, some will use an experienced team to set the line – some may even use a combination of all three. Other books may even wait to see where their rivals set their lines before dipping their toe in the water themselves.
The last types of bets that you should be aware of when betting on the NBA are proposition bets. A prop bet is a wager in which you bet on whether or not something is going to happen in a particular game. For example, will a certain player make more than four 3-pointers in a game? Which team will score first? Which team will win the opening tip-off? Will a certain team shoot over X % from the field? All of these are examples of prop bets that you can make on a particular NBA game.
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.
On a moneyline bet of -300, you’ll need to win your bet 75% of the time just to break even. When your odds jump even higher to -400, you’ll need to win your bet 80% of the time to show a profit. You are risking a lot to win very little and even though a large favorite will win most of the time, when they do lose, you will find yourself out a lot of money. I try to stay away from large favorite moneylines, because the amount risked is very high and the payoff is low.
Used in high-scoring sports like NFL and NBA, the point spread is a handicap that is placed on the favorite team in terms of points for betting purposes. If 10 points favor the Broncos over the Seahawks the point spread is 10. The Broncos must win the game by 11 or more points for you to win your wager. If you’ve made your bet on the Seahawks, you’ll win your bet if your team wins the game or losses by nine points or less. If the Broncos manage to win by exactly 10 points then the bet will be a tie.
Typically, if you’ve made a bet on sports in the past amongst friends or at the casino, you probably made a moneyline bet, and you didn’t even know it. “I bet you $10 the Broncos are going to win tonight.” That’s a moneyline bet. You may also hear the bet referred to as a to-win bet in some circles, but just know that they are referring to the same type of bet.
The first part of each line tells you who you are betting on. The first line is a bet on Mike Tyson and the second line is a bet on Old Man River. Next, you’ll see a plus or a minus sign. The plus sign signifies the fighter who is an underdog, and the minus sign signifies the fighter who is the favorite. As you can see, Mike Tyson is the favorite and Old Man River is the underdog.
Moneyline bets can be presented in three different formats including moneyline, decimal, and fractional. While these will look very different, they will tell you the exact same information about the bet including who you are betting on, who the favorite or underdog is, and what the potential payout you would receive from a correct pick. We will cover all of this in the next few sections.
Anybody who wagers on the 49ers would need them to win by 7 points or more for a winning bet. Those betting on the Rams (+6.5) would need them to lose by 6 points or less (or win) for a winning wager. It's also worth mentioning that a half point is used in many point spreads (such as the -6.5/+6.5) to prevent pushes because no team can score half a point.
For example, let’s say that two players are playing a tennis match and one player is +250. You think that this player has a MUCH better chance than that but still is an underdog. Most people would tell you that you are crazy to make a bet on someone that you think is going to lose. The thing is, though, underdogs do win and if you’re getting paid more than you should when they do, you’re going to be profitable. Here’s a simple math breakdown.
Sports spread betting began in the United Kingdom in the late 1980s to offer an alternative form of sports wagering to traditional fixed odds, or fixed-risk, betting. With fixed odds betting, a gambler places a fixed-risk stake on stated fractional or decimal odds on the outcome of a sporting event that would give a known return for that outcome occurring or a known loss if that outcome doesn’t occur (the initial stake). With sports spread betting, gamblers are instead betting on whether a specified outcome in a sports event will end up being above or below a ‘spread’ offered by a sports spread betting firm, with profits or losses determined by how much above or below the spread the final outcome finishes at.
Let's use this formula to calculate the implied probability of the Celtics winning their game against the Grizzlies. We know the odds are -240, which means we'd have to risk $240 for a total potential return of $340 (the initial stake plus the $100 winnings). So the calculation here is $240 divided by $340. This gives us an implied probability of 0.7059.
The last type of handicap bet that we want to talk about is an Asian handicap bet. Don't worry, you don't have to be Asian to place this bet; it's open to everyone. This form of handicap bet is set up through the use of whole, and half number point spreads to ensure that no draws are possible. The difference between Asian handicap bets and no draw handicap bets is that the Asian handicap bets have the possibility of what is called a split handicap outcome. Your bet will have a whole number and a half number line that are treated effectively as two separate bets, but all in the same bet.
Here’s a less extreme example. Let’s say that Fighter A is fighting Fighter B and you think that Fighter A is going to annihilate Fighter b. Like you don’t even think it’s going to be close. Let’s say you decide that you would be willing to bet even if the odds were -400 on Fighter A. You’d only be getting $25 back on your bet, but that’s what you think is fair.
That was all before Charles McNeil, a math teacher from Chicago, invented the concept of the point spread. An avid gambler, McNeil created what he called “wholesaling odds” and started his own bookmaking operation in the 1940s. He started out offering this new style of betting on football, but his business model grew to include basketball. McNeil changed the way sports betting was done, and his legacy lives on today in what we now call the point spread.
