Understanding Odds

For anyone new to betting, understanding how odds work is very important. The odds for an outcome essentially tell you how likely a sportsbook thinks it is likely that outcome will happen.

OddsBoom offers odds in two formats: American (e.g. +200), and Decimal (e.g. 3.00). The default is American, but you can change it on any page where odds are displayed.

Understanding Odds

American Odds

American odds are displayed either as a positive or negative number. Positive means this is the amount you get back for a $100 bet.

For example, an outcome at +350 yields a return of $350 for a $100 stake. Negative numbers indicate the amount you need to place to win $100. For example, an outcome at -200 means you have to place $200 in order to win $100 profit.

Decimal Odds

Decimal odds are somewhat easier to understand than American odds, as there is basically only one format.

The number displayed is how much you win per dollar placed. For example, an outcome at 6.5 means you win $6.50 for every $1 bet.

Getting the Best Odds

Knowing what the odds mean is one thing, but it's also important to get the best odds available for your bets, every time you bet.

Imagine a scenario where you place 1,000 ten-dollar bets over the space of one year. If you only have an account with one sportsbook, and their odds are -110 for each bet, and you win 60% of the time, your profit will be $1,460.

Now let's imagine the same set of bets, but this time you shop around and get the best line possible, which is -105 on every bet.

In this second scenario your profit is $1,700 - a 16% increase.

Winning at sports betting isn't easy, and an edge like this should always be taken.

Getting the Best Odds

Using Odds Comparison

So you've decided to get the best odds. Now you'll need to understand how to do it. Simple!

Any odds on OddsBoom.com that are highlighted in
bright yellow are the best odds available with legal sportsbooks in your selected state.

These are the odds you should always try to bet. If you don't have an account with that book, open one and take advantage of the many signup bonuses available.

Getting the Best Odds

Take a look at the example on the right.

In this case, you'd be pretty crazy to take the odds available at Bet365, even if it's only a small stake.

For a $50 bet, you'd lose out on $6 of profit if you took the Bet365 odds over the best available line at Caesars. That's a 12% difference.

That's why it pays to shop around for the best line every time you bet. You just don't know who's going to have the best odds and by how much.
