The + number is the amount that you would have to bet to win \$100 while the – number is the amount that you will win if you bet \$100. In this case the line will look something like this:. If you look at the line for any game, the favorites will have odds displayed with a + sign in front of the number while the underdogs would have a – sign. If you think that the total is going to be less, you would bet the under and if you think that the total is going to be more, you would bet the over.

Team A -10  +110

Team B +10  +110

Here are the more popular forms of bets that you can place:

If the majority of sports betting in the USA revolves around the four major sports of football, basketball, baseball and hockey, there is plenty of action available on other sports such as horseracing and boxing. For instance, +130 means that you bet \$130 to win \$100 while -130 means that you win \$130 for a \$100 bet.

This means that if you bet on the favorite Team A and they are ahead even after you subtract 10 points, you win. In case you do not wish to choose either team, you have an alternative. If you are betting on sports in the USA, you have a wide variety of betting options ranging from your friends to your local illegal bookmaker. Apart from the USA, the online sports books also allow bets on different sports in different countries so you are sure of making the bet of your choice. In order to encourage people to bet evenly on both teams and thus balance the risk, bookmakers have invented the point spread. The line for this kind of bet looks something like this:

Point spread bets. If some people bet as a profession, lots of people such as yourself simply bet for fun. Because the two teams, at least in theory, are equal, you will receive the same odds. They decided on a point number which they believe will equalize the scores of the two teams and this number is added to the underdog and subtracted from the favorite. The best option is, however, to use an online sports book for the following reasons:

This means that Team A is the favorite and you need to bet \$330 to win \$100. A bet of \$100 on Team B to win will fetch you the return of \$150.

Betting the under/over. If you are betting on US sports, you will generally find the odds displayed in what the bookmakers call lines. From time immemorial, where there has been sport, there has been sports betting. If you pick the other team and they lose by less than 10 points, you win. For many of them, the minimum bet is as little as one dollar.

Moneyline bets. The temptation to spice up watching a sport by making a small bet is almost irresistible. These are the simplest bets where you simply pick the team that you think will win. The book makers will post a number which they think will be the total score by both teams put together. In games like baseball, the point spread is called the run line.

These are the most common forms of betting but you can also choose from a variety of other bets such as parlays, progressive parlays, teasers and futures.

Team A -330

Team B  +150
