When you bet on the money line, you are betting on one side to simply win. Any time you see a money line, the minus sign (-) indicates the favorite while the plus sign (+) indicates the underdog. For example: Chicago Bears –240 vs. Minnesota Vikings +210. Using $100 as the base, it will take $240 wagered on the Chicago Bears to win $100. For a bettor wagering on the underdog Minnesota Vikings in this scenario, $100 will win $210. With the money line you just have to hope your team wins rather than cover a point spread. Of course, the one downside is having to risk more money to return the same amount that a point spread bet would net you.

Understand that negative odds indicate how much money your must spend to make $100. When betting on the favorite, you take less risk, and thus earn less. When betting on a favorite, the moneyline is the amount of money you need to spend to make $100 profit. In the previous example, in order to make $100 of profit betting for the Cowboys, you would need to spend $135. Like positive odds, you earn back your bet when winning.
Here's an example: Imagine that using the money line above with the White Sox and the Astros, you want to win about $100. If you place your bet on the favored White Sox, you will pay the bookie $120. If you win, you get your $120 back, plus $100 in winnings. If you lose, the bookie keeps your $120 (technically, bookies collect on losing bets after the game most of the time, but for our example we'll assume the bet is prepaid). If you bet $100 on the Astros, you'll get $110 in winnings if they win, and only lose $100 if they lose.

The biggest advantage of the moneyline for the NBA is that your team doesn't have to overcome the point spread for you to win your game. If your handicapping leads you to believe that one team is likely to win but you can be less certain that they will win by as much as the point spread then the moneyline may be attractive. You are sacrificing some potential return because the moneyline won't pay as much for the favorite as the point spread will, but it's obviously better to make a small profit than it is to lose a bet. This is particularly attractive in basketball because the favorites can often face large point spreads and teams can win comfortably and effectively without covering the spread.
Since more people wager on football than any other sports it’s usually the easiest game to figure out how to bet. If you don’t know what to do, you can probably ask anyone in the sports book for instructions. The people visiting the casino might not know everything but they can give you the basics. Here’s a fairly thorough look at the different ways you can wager on football in Las Vegas.
A teaser is a bet that alters the spread in the gambler's favor by a predetermined margin – in American football the teaser margin is often six points. For example, if the line is 3.5 points and bettors want to place a teaser bet on the underdog, they take 9.5 points instead; a teaser bet on the favorite would mean that the gambler takes 2.5 points instead of having to give the 3.5. In return for the additional points, the payout if the gambler wins is less than even money, or the gambler must wager on more than one event and both events must win. In this way it is very similar to a parlay. At some establishments, the "reverse teaser" also exists, which alters the spread against the gambler, who gets paid at more than evens if the bet wins.
For reading the fraction odds, I strongly recommend converting them to a decimal. This will make figuring out your potential win much much easier! To do this, just like in 2nd grade, you take the first number and divide it by the second. So if your odds read 7/4, you simply divide (7) by (4), which equals 1.75. That is the decimal form odds, now you simply multiply (1.75) by whatever your wager amount is to figure out your potential profit. In this case, if you were to risk $100, then your potential win would be $175 profit if you are correct! Also, you will receive your initial bet amount of $100 as well, for a total of $275 in your hand.
The most important thing you can teach yourself early on is: "Just because the books assign one side to be the favorite (even large, -200 or -300, favorites), does not mean that they will win." We have all seen favorites get upset, and it is important to avoid the temptation of finding comfort in the fact that the lines makers put one team as a favorite. 

If the bookmaker was only confident enough to give Seattle a field goal’s lead on the Patriots, it was clearly going to be a tight game. Oddsmakers aren’t often that wrong about flagship games like the Super Bowl. All things being equal, it’s likely the betting public would have taken the Seahawks to win the game and have been done with it. But throw in the point spread that gave the Patriots 2.5 points, and the proposition seems more equal.
You may often notice that the spread is sometimes set at an even number such as 3, 6 , 10, etc. In this case if the favored team won by the exact amount set for the spread the bet would be pushed, and all bets would be returned. For example, if the Patriots were 3 point favorites and they won by a FG (3 points) than this would results in a push, meaning no matter which side you bet on you would get your money returned to you.
A point spread - Lets take, for a hypothetical situation on one of the types of football bets (using the point spread), that the Kansas City Chiefs were visiting the Detroit Lions and Detroit was established as a six-point favorite at game time, which is commonly written as Detroit -6. Kansas City would be the underdog and displayed as Kansas City +6. If you bet the favorite, Detroit has to win by more than six points to win your bet. Remember, the Lions are favored by six points, so we subtract six points from their final score on a spread bet. If Detroit were to win 27-20, Lions bettors would win their wager. If the Chiefs were to win the game by any score and you picked the Chiefs you would win not including the extra six points. If the Lions were to win, 20-14, it would be exactly six and a push, so you would get your money back.
Sometimes a line will move far enough to create a “middle” opportunity. Say the Texas Longhorns end up facing the Wisconsin Badgers in the first round of March Madness. If you have Texas early as a 5-point favorite, and I move the line to Texas –7 later in the week, then you can also place a bet on Wisconsin +7. If Texas happens to win by six points, both your bets cash in. Texas winning by either five or seven gives you a win and a push. Any other result creates a win and a loss, so you’re only risking the vigorish.
Because the spread is intended to create an equal number of wagers on either side, the implied probability is 50% for both sides of the wager. To profit, the bookmaker must pay one side (or both sides) less than this notional amount. In practice, spreads may be perceived as slightly favoring one side, and bookmakers often revise their odds to manage their event risk.
For example, if you want to bet that -140 favorite, you’ll need to risk $140 in order to win $100. To bet on the +120 underdog we mentioned above, you’ll need to bet $100 to win $120 if the dog wins outright. In many cases, betting moneylines offers better value and can provide a bigger profit for less risk. Check out our NFL Betting Guide to learn more about when you should bet a moneyline instead of a point spread.
One of the first rules of gambling is that nothing is ever certain. There's one thing that's almost certain though; you will make mistakes as a beginner. This is nothing to worry about, and in fact making mistakes is an important part of the learning process. That doesn't mean you need to make unnecessary ones though. There are a few mistakes that are routinely made by beginners, and it pays to be aware of these.
When you’re looking at over under bets, what you need to know is that that’s the combined score of the two teams for a game. In this case, it doesn’t matter who wins the game. All that matters is the final score. For example: let’s say that the New York Yankees are playing the Boston Red Sox and the total is 9.5. It doesn’t matter who wins the game but if the two teams combine for a total score of eight runs, say with a final score of Boston winning 5-3, then the game goes under. Or if the two teams combined for 10 runs – no matter who wins – then the game goes over. So when you’re looking at the odds and you see a total next to the moneyline or point spread, that tells you the over-under that is set for the game and you have to decide whether it will go over that set amount or under.

The majority of bets on any sport are usually on the final outcome of the particular contest. However, for sports like the NFL and NBA, there are 1st quarter and 1st half lines offered as well. The quarter spread is used to determine who will be the winner at the end of the 1st quarter. The same is true for a 1st half line, only the wager ends when the first two quarters are completed. Generally, the 1st half spread will be close to half of the overall spread on the game.
The divisional round of the NFL playoffs concludes on Sunday, and we’ll know which four teams have a chance to win Super Bowl LIII after two must-watch games. Tom Brady and the Patriots will try to earn their fourth consecutive AFC Championship berth, but is it finally Philip Rivers’ year? In the NFC, Nick Foles led the Eagles to a stunning upset of the Bears, but can the defending Super Bowl champions take down the No. 1 Saints?

Also known as NFL OVER/UNDER betting, the total is the number set by sportsbooks that estimates the total number of points scored by both teams combined. Bettors then must predict whether there will be more or fewer points than the NFL “total.” If you bet the 37.5 UNDER, you are hoping for a defensive battle and predicting the offenses to struggle. If you bet the 37.5 OVER, you are hoping this will be a high-scoring game.
