In this example the Jets are listed as four-point favorites (-4) over the Bills and the 49ers are three-point underdogs (+3) against the Seahawks. So, if you bet $110 on the favored Jets, they must defeat the Bills by more than four points in order to win $100. If you bet $110 on the underdog 49ers you will win $100 if they win outright or lose by less than the three-point spread. If the final score happens to end up exactly on the number it's a tie, or 'push,' and you get your money back.
There is no magic formula for moneyline betting, you’ll simply need to pick your spots wisely and balance your risk versus your potential reward. In general, I think this means taking higher upside picks, such as underdogs rather than taking large favorites. However, bettors should analyze each game independently looking for value in both favorite and underdog moneylines.
This means that the people betting the big bucks are going to end up shifting the line considerably. A lot of times, you will see a moneyline released, and then it will quickly shift. Usually, this is a skilled big bettor taking advantage of what they think is an opportunity. Ideally, you’ll want to jump on bets before these skilled bettors get ahold of it.
This also comes into play on games that you think the line is correct. For example, let's say you think the line of Florida -7 is correct, so you elect not to bet it because there is no value. This doesn't mean you should never look at this game again. If the line happens to shift in either direction, you can make a bet that has value. If the line moves to Florida -6, you place a bet on Florida because you originally thought they would win by seven. If the line moves to Florida -8, then you place a bet on Arkansas at +8 because you originally thought Florida would win by seven and Arkansas would lose by seven. The next strategy tip is a good idea to help you be ready for these situations.
Identify the type of line you are looking at. All online sports books offer you the chance to have your lines in an "American" or "Money line" version. If I were you, I would use this as my standard. An "American" line uses either a + or - before a number to indicate odds. So a -120 and a +120 are two very different odds on a team… I will explain the differences shortly. Two other less common variations exist: decimal odds and fractional odds. 

Another popular form of golf betting involves matchup propositions, in which two golfers are paired against each other in a head-to-head wager, with a betting line on each golfer set by the oddsmaker. The golfer with the better (lower) score wins the matchup. (If one golfer continues play in the tournament after his opponent misses the cut, the golfer who continues play wins the matchup.)

Of course, it wouldn’t be. Everyone would bet on Mike Tyson, and the sportsbook would lose all of their money and close the next day. So what the sportsbooks do is they assess who is the favorite and who is the underdog and assign a value to how much in each direction they think they are. Let’s look at what the odds might look like for our fictitious fight and break down what everything means.

In cases when there is a point spread and moneyline offered on an event, such as an NFL football game, many bettors will place a wager on the moneyline and point spread of an underdog they feel has a chance to pull the upset. They will safely bet the point spread because they feel the game will be close, but will also put themselves in line for a nice payday if the underdog wins straight-up.

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.

Understanding how a moneyline wager pays isn’t simple but it’s not very complicated. That said, it might take running through a few examples before fully grasping the payouts. Moneylines for football and basketball games are often tied to the point spread. When a game has a large point spread it usually has a large moneyline. Both are separate bets but are shown together in a sports wagering app screen and in a brick and mortar sportsbook.

The two results above are the no-vig probabilities. If you're sharp, you'll notice that adding 68.57% and 31.43% up together will give you 100%. The extra 2.95% has been removed, so there's no more vig. We can now go to our odds converter and enter 68.57% into the implied probability field. This will give us moneyline odds of -218. If we enter 31.43%, we'll get moneyline odds of +218. The original moneyline market of the Celtics at -240 and the Grizzlies at +210 therefore has no-vig odds of the Celtics at -218 and the Grizzlies at +218.

Some people consider sports gambling a disease which is why it is outlawed everywhere in the United States besides Las Vegas. However, many Americans still bet on sports illegally with various overseas bookies. Because of this, many Americans believe sports gambling should be made legal throughout the United States because the country is missing out on millions of potential tax dollars by sports gamblers using overseas bookies.
Moneylines are a viable alternative to point spreads when betting on football. If you're one of those bettors who only ever bets on the spread, then you could very well be missing out on some good opportunities to find better value. We don't recommend that you stop placing point spreads and only place moneyline wagers, but you should definitely consider both when betting on a game of football. Try to decide which one offers the better value, and then go with that option.
The point spread, which is sometimes referred to as the “handicap”, is the number of points taken from the favorite, or given to the underdog, in order to open up the chances of either team winning the wager evenly. In most games, there’s usually a team that is more likely to win, based on a number of statistical factors. If the only kind of wager available was on who would win between a very strong team and a poor team, it wouldn’t be all that exciting. The point spread was designed to make betting much more interesting, since it allows a bet on the losing team to win you money. How? Let’s break down an example:
