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.

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.


A common mistake that new bettors will do is to bet every single game. Unfortunately, this is not a winning strategy no matter how sharp you are. Stick to betting the games where you actually see value. Here's what we mean by value. Let's say in our earlier example that you agree with the sportsbook that the Florida Gators should win the game by seven. You should not bet this game then no matter what if the line is -7. If you're right, the best you can do is tie on your bet. When you pick a side, you're basically going to be guessing and flipping a coin. Theoretically, you'll win as many times as you lose, but you'll be paying the house percentage every single bet and slowly bleeding your money and profits away.
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.
Without point spread betting, placing a wager on our team to win these games would be financial suicide. Point spreads create an even playing field for sports bettors. Even if your team is supposed to lose by 20 points, you can still bet on them if you think they're going to have a better day than predicted. If you've ever wondered why someone was still cheering and going nuts at the end of a blowout, you can bet they were sweating a point spread bet.
You should already know that the Eagles are the favorite to win and that you should expect less than even money on a correct pick here. You should also know that the Falcons are the favorite, and you should expect better than even money on a correct pick here. Having this in mind every time before you start your calculations will protect you from making a mistake and calculating the completely wrong direction.
If you are able to interpret NFL odds and know what the various terms mean, such as the rotation number, point spread, moneyline and over/under, you’ll have a basic understanding on what you are betting. Prior to wagering make sure you see our NFL odds page, which carries all the latest odds from the top online sportsbooks. Remember that the odds makers are attempting to even the out the bets on each game. The sports bettor has to analyze each game and the odds and make their bets accordingly in order to win cash.
Straight bet - Amid all the fancy and lucrative-looking bets that are available, never lose sight of the value in a standard straight bet. You probably should learn and practice this bet often before learning any others, and it should be noted that people who bet for a living or a large portion of their income place straight bets almost exclusively.
With money line bets the goal is to pick the outright winner of a game or event without the use of a point spread. While money line betting is available for sports where point spreads are used, they’re most popular in sports like baseball and soccer where very few points are scored. Money lines are also used for sports where points do not determine the winner or loser, as in auto racing or tennis.
As we did with the underdogs, we need to figure out how much we will profit for each $1 that we wager. For underdogs, we divided the moneyline number by 100. For favorites, it is the exact opposite. We will take 100 and divide it by the money line number. So, for this example, we will take 100 and divide by 155 and get about $0.645 or about $0.65 in profit for every dollar that we bet.
An over-under bet in basketball is a wager on whether the total score for the game from both teams will be above or below a certain threshold. This is a great bet to utilize when you think that a game will be defense heavy and both teams will be shooting cold, or when you think that it’s going to be a barn burner with both teams shooting lights out.
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.
This should hopefully make perfect sense to you. Successful betting, on any sport, is all about finding value, so you should always look to get the best value that you can. If a moneyline wager offers the best value on a football game, then that's the wager you should be placing. If a point spread seems the best option, then go down that route. There may even be occasions where it's viable to place both wagers on the same game.
In most cases, the favorite will be the team with a negative moneyline (in some cases both teams can have a negative moneyline if they are both closely matched). A line of -160 means that you would have to bet $160 to win your base amount of $100. A team with a moneyline of -130 wouldn't be favored nearly as strongly as a team with a moneyline of -330.
‘Extra-Time’ wagers apply to 30 minutes of play according to the match officials, plus any added injury or stoppage time. However extra-time and penalty shoot-outs are not included. In ‘Extra-Time’ markets, wagers apply to the result during the extra-time period only. For the purposes of this market the score shall be deemed to be 0-0 at the start of the extra-time period.

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.
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.

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.
Spread betting is one of the most popular forms of betting for sports enthusiasts and it involved speculating the outcome of a game or a match and trying to guess what the score will be and what he spread is between the two final scores of the game. With sports betting, spread bets allow punters to bet on if a team’s final points are higher or lower than a projected total. Many pointers rely on tips when they are spread betting. The first is that punters should always choose an even bet and make sure it is one they are comfortable with. Always take time to learn the stats and performance record for the teams involved so an education decision can be made.
We mentioned we would touch on the -3500 bet in this section. If you calculate the implied probability of -3500, you see that it is 97.2%. This means that the bet will have to hit 97.2% of the time for you to break even. Now, if you think that the bet is actually 100%, then it might be a smart bet to make. You’re still going to have to put up a lot of money to see any real sort of profit, which might not be desirable based on your personal preferences.
Let’s say you decide to bet $100 on the Packers to win by more 7 points and the final score is Packers 30, Seahawks 21.  The Packers have won by 9 points, meaning they’ve covered the spread, and you’ve won the bet. The -110 means that your $100 bet will win you a total of $190. That total includes your original bet amount, so your total profit is $90.
