Apply the money line. It's easiest to think of money lines in relation to $100. A minus sign means you have to bet that much money in order to win $100; a plus sign means that a $100 bet will return that much money. If you bet on Chicago at -110, you'll have to wager $110 in order to get back $100 (plus your original $110). If you bet on Detroit at +145, then a $100 bet will give you $145 (plus your original $100).
Placing a point spread bet means gambling on how much a team will win or lose by. In our above example, the Cowboys are the favorite. How do we know that? The minus symbol in front of the point spread indicates that the bookmaker thinks the final score will have Dallas winning by 7.5 points or more. The underdog, in our example that’s the New York Giants, will always be indicated with a plus sign. If you wager on the Cowboys on the point spread, America’s Team will have to win by at least 8 points for your wager to pay off. Should the Cowboys win by less than 8 points, your bet is lost.
In the United States, most bookmakers use the moneyline format to express the odds they offer for wagers. Thus, moneyline odds are also commonly referred to as American odds. They can be either a positive number or a negative number. A positive number shows how much profit a winning wager of $100 would make, while a negative number shows how much needs to be staked to win $100.
A lot of people who are new to online betting aren’t aware of prop bets, because a lot of brick-and-mortar sportsbooks just don’t have the resources to allow them. These bets are a great way for you to make some extra money off of predictions that might not have a direct outcome on the winner of the game. For example, let’s say you think that the Warriors are going to shoot lights out from the field, but you think for some reason they aren’t going to get a lot of looks and are going to lose the game. Your only option without prop bets would be to bet on the team they are playing against, but that might not be a great value bet.
We're often asked a question along the lines of "why would I place moneyline wagers rather than point spread wagers?" There's no simple answer to this question really, as point spreads and moneylines shouldn't be viewed as "either/or" options as such. You don't have to decide that you're always going to bet on the spread, or that you're always going to bet moneylines. These are two different wager types that have their own merits, and any bettor should have them both in their arsenal.
Bets on "Race to X Points / Race to X Goals..." and similar offers refer to the team/participant reaching the earliest particular tally of points. If the offer lists a timeframe (or any other period restriction) it will not include any other points tallied from other parts of the event which are not related to the mentioned time frame. Should the listed score not be reached within the stipulated time frame, all bets will be declared void, unless otherwise stated.
Point spreads are more common in the United States, but you can see them throughout the world. A point spread, in theory, is the sportsbooks attempt to create a "level playing field." Let's look at an exaggerated example that will make this clearer. Let's say the New England Patriots are playing a game against a junior varsity high school football team. They're also using deflated footballs, and the Patriots get to see the high school team's playbook before the game. If a sportsbook were to allow you to bet on which team would win, everyone would bet on the Patriots as they would probably annihilate this other team.
If you wager $100 cash on odds of +100, you are staking $100 cash to win $100 cash. Your total potential return is $200, which is your initial stake plus your winnings. If you wager $100 free play on +100, however, your total potential return is just the $100 winnings. Whether you win or lose, your free play is used up. Obviously, free play bonuses aren't worth as much as cash bonuses, so that means it's up to you to squeeze as much value out of them as possible.
Bets on “Winner of Point”, “Scorer of Goal" and similar offers refer to the participant winning the listed occurrence. For the settlement of these offers, no reference to events happening prior to the listed occurrence will be taken into consideration. Should the listed event not be won within the stipulated time frame, all bets will be declared void, unless otherwise stated.

With NFL odds the over/under can vary but usually it’s somewhere between 35 and 47 points. Let’s say in the Colts and Bengals game that the total is posted at 37.5. If Indy scores 27 and Cincy gets 13 points, the total would be at 40 and the over would win. But if the Colts rack up 35, and they shut out the Bengals, the total of 35 would be under.
You see, people too frequently get caught up on their win-loss rate, which actually has no real effect on their bottom line. You can win more bets than you lose and still be losing money. On the other side of things, you can lose more bets than you win and be wildly profitable at sports betting. It all comes down to successfully finding value and pouncing on it when you see it.
If you’d prefer to simplify things and only bet on whether a team wins or not, moneyline bets are going to be more of your style. A moneyline bet is a wager on which team wins the game. If the team you bet on wins, you win. If they lose, you lose. As we’ve stated earlier, the sportsbooks must do something to ensure they get as close to an even amount of money on both sides of a bet. With spread bets, they alter the number of points a team must win or lose by.

The number-one key to success here (as it is with any type of sports bet) is understanding what value is and knowing when and how to take advantage of it. Value, in a nutshell, is finding sports bets that are paying you at a better rate than you think they should. If you place enough of these bets to overcome variance, you’re going to be a long-term winner.
We've already mentioned how moneyline wagers give you more control over the risk versus reward element of betting. There are also other reasons why you might choose this type of wager over a points spread. If you fully understand how both of these wagers work, you'll find that there are games when a moneyline wager is the right option, and games when the point spread wager is the right option. There are no definitive rules about which one you should use and when, only a general principle that you should try to follow.
The first thing you’ll notice with moneyline odds is that there is either a positive or negative sign in front of the number. What that sign denotes is how much you’ll win betting on each side. If there’s a positive sign next to the odds, that indicates the amount of money you would win if you bet $100. If the odds on a tennis player said +150, that means that for a $100 bet, you would win $150. Now if there is a minus sign in front of the odds, that is the number that you would have to bet in order to win $100. For example, if a football team was -250, that means you’d have to bet $250 to win $100.

But what if the basement-dweller team was spotted 24 points? That's the concept behind the point spread. When two teams meet on the football field or a basketball court, one team is typically better than the other. If all bettors had to do was to pick the winning team, everybody would simply wager on the best team and collect their money. Gambling institutions, sportsbooks, and bookies would soon go broke. 
Moneylines have a tendency to move quite a bit in both directions leading up to a game, match, or fight. It’s a delicate dance that you’re going to have to master if you want to find value and push your edges to the max. Sports betting is a profit source that is all about small edges. Finding and being able to capitalize on these small edges is the key to being profitable long-term.
In sports like football and basketball, the moneyline is considered as the secondary option next to point spreads. Points spreads are the way that most people get their action in on basketball betting and football betting because the payouts are near doubling your money and it’s a fun way to handicap the game. Betting the moneyline in those sports is less popular because you might have some big mismatches and then it becomes too challenging to have faith in the underdog winning outright or too costly to bet the favorite.
All point spreads are set by the pool administrator. NOTE: The administrator has the power to change the point spreads at any time up until 15 minutes before the start of the first game, so make sure you know when the administrator will make the final changes. For your own information you should also find out where the administrator is getting their point spreads.
Especially in major tournaments, some sports books offer odds on unusual golf propositions, such as the over/under on the winning score, the over/under on the lowest round by any golfer or the over/under on the finishing position by a particular golfer. For example, the over/under on Woods' finishing position may be 3 1/2. If he finishes first, second or third in the tournament, the "under" wins; if he finishes fourth or worse, the "over" tickets cash.
