Online Sportsbooks With the Best Odds in 2021

A small increase in the odds for every wager you place can make a big difference to your overall betting results in the time. So can finding lines that are just a point, or half-point, more in your favor.

That’s why it’s important to use online sports betting sites with the best odds and lines.

Let us ask you a question.

What do you do before you shop? Before you buy something expensive?

We don’t know about you, but we usually window shop first.

We’ll look online or browse a couple of stores to see which one has the best deal and has the product (with features) we want at the lowest price.

And you know what? Sports bettors do the same thing. The smart ones, anyway.

Smart sports bettors check the odds or lines offered by a handful of different sportsbooks – sometimes even more if their bankroll can handle it – before they choose where to place their bet.

Often times that can be the one thing that determines whether they make a profit or not.

But what if you don’t want to price shop dozens of sportsbooks? What if you’re not sure how to do that?

Well, the next best thing is to join a sportsbook that consistently offers the best prices. In fact, you should join two or three of them (for reasons we’ll talk about later).

How do you find these sportsbooks? You can do the research yourself, but if you could do that, you probably wouldn’t be here right now. You’d probably be out on your own making profitable bets.

A much faster and simpler option is to piggyback off of our hard work. We’ve already done the research for you. The online sportsbooks that consistently offer the best odds and lines are in the list above.

Online betting sites with the best odds and lines

Why Does Finding the Best Odds Matter?

The short answer – because it’ll save you money.

For example, say you compare lines from two different sportsbooks. One is offering -105, while the other is offering -110 on the same match.

It makes far more sense to take the line at -105 than -110.

You might roll your eyes at this. There’s hardly a difference there, you think – nothing worth worrying about.

But you’d be wrong.

Say you only plan to bet $1. The difference here is a mere $0.05. But say you make one bet every day. That’s $1.50 you’ll save over the course of a month – or a little more than one free bet.

Now think about it if you were to bet $110 vs. $105. That’s a $5 difference. One bet every day adds up to around $150 per month. For most people, that’s an amount worth saving.

Next, imagine if you were betting $500, $1,000, or as much as $10,000 per bet. Do you see how much you can save when you don’t ignore something as “trivial” as the difference between a -105 and -110 line?

The bottom line – the larger your bets and the more bets you make, the more money you’ll save.

And besides, it’s easy money when you consider that all you need is an account with the sportsbook(s) that (consistently) offer the best prices.

You Should Look at Point Spreads, Too

Take two lines from two sportsbooks – Book A offers a spread of -6, while the Book B has a spread -5.5. Seems like a tiny difference, doesn’t it? Like the difference between a -105 and -110 moneyline?

But the latter is the easier of the two to achieve. The team only needs to win by 5.5 points for you to get a return for betting on them.

Which is easier? Beating a team by 5.5 points or beating them by 6? Clearly, the smaller of the two is the easiest.


Not every point difference matters. We explain why in just a minute.

The fact that beating the 5.5 point-spread is easier than 6 has a long-term positive expected value in itself. It’s going to happen more often, thus you’re going to make more money betting it. But then things compound when you also compare and find the best moneyline.

Here’s an example:

Say that Book A is offering odds at -115 with a -6 spread, and Book B is offering a -5.5 spread at odds of -105.

Not only are you going to beat the spread more often by betting at Book B – which means you’ll make money a little more often than with Book A – but you’ll also save (or make) $10, too.

Do you see how powerful this is? How you can explode your long-term expected value at an exponential rate? All by simply finding these seemingly little differences between sportsbooks.

Or by simply joining sportsbooks who offer this kind of value often.

Not All (Half) Points Are Created Equal

We want to play devil’s advocate for a second. Having a bit of difference between point spreads doesn’t guarantee it’s a good deal. Sometimes the difference is too small, or for some other reason, the bet itself doesn’t make much sense.

Say you’re looking at the Patriots vs. Bills game. One sportsbook (Book A) has Buffalo at +6.5 and another (Book B) has them at +7. Both have a standard vig of -110.

Clearly, taking Buffalo at +7 is the best deal because if the Patriots win by 7, you’ll get your money back, while anyone taking Buffalo at 6.5+ will lose.

While this half a point difference seems small, for this bet (and game) it makes sense and will add up over time.

But say we look at another game – the Patriots vs. the Steelers. One sportsbook (Book A) offers New England at -1.5, while another (Book B) has them at -2.

Is this a “great” bet? No way – and here’s why:

The chances of New England winning by exactly 2 points is very slim (and while too large a topic to cover here, it’s also not enough of a difference to overcome the house edge when betting at -110).

The point spreads that matter will vary from sport to sport. For example, the key numbers for the NFL are 3 and 7. Knowing this, you should look for sportsbooks who offer different moneylines and point spreads that are around these numbers.

This goes to show how much experience can help, too. And why it’s important to focus on a couple of sports until you become a consistently profitable bettor.

It also shows why professional sports betting – and all the work involved – isn’t for everyone, which is another way of saying that you’re better off sticking to one of our recommendations above. Because you’ll have your work cut out for you if you want to do the legwork yourself.

Three Other Things to Think About

So far we showed you why price matters, but also why you should look at point spreads, too.

But that still doesn’t cover everything. There are still three things you should think about other than price before choosing a sportsbook, much less what you’re going to bet on next.

1Dual Lines

Some sportsbooks have dual lines.

Dual lines are two different lines or odds – one for the public, and the other for the professional or advantage bettor.

Bovada is a good example of a sportsbook who has dual lines. New accounts start off with the same lines as everyone else. But if Bovada gets the feeling that you’re a +EV bettor, they’ll change your account and give you different (worse) odds.

Here’s an example from an old 2+2 thread of this happening to someone else:

Anyone notice Bovada shaving lines immediately when you log in or is it just me?

For example, I’ll go to Bovada and look at the Football Thanksgiving lines tomorrow:

Houston Texans -4 (EVEN)

Detroit Lions +4 (-120)

New England Patriots -7.5 (-105)

New York Jets +7.5 (-115)

I log into my account, and this is what I see:

Houston Texans -3.5

Detroit Lions -3.5

New England Patriots -7 (-115)

New York Jets +7 (-105)

Once again, it’s a small difference – but these are differences that will add up over time.

We point this out because if you’re a halfway decent bettor, there’s a chance this can happen to you. And it will ultimately impact your decision as to which sportsbook you should join.

2Think About Reduced Juice, Dime, or Discounted Lines

The same idea applies here. All things being equal, you just want to find a sportsbook that’s offering the best lines.

But what if the sportsbook offers discounts, dime lines, or reduced juice? That should play a role in your decision, too.

Many sportsbooks, like 5Dimes and BetOnline, offer dime lines and/or reduced juice. They have certain rules for betting these matches or taking advantage of these promos. But if you plan to make lots of bets, they’re worth a look.

3Are There Any (Hidden) Fees?

Most online sportsbooks are “betting exchanges.” Exchanges charge a commission, which is calculated as a percentage on the net winnings for each customer on each event or market.

This is a cost that ultimately affects the lines/odds you pay. It’s a hidden cost.

The upside – when compared to traditional sportsbooks like Pinnacle – is that the odds you pay are still usually better than the odds offered by traditional sportsbooks.

On top of that, traditional sportsbooks like Pinnacle – which have tons of good things about them – don’t offer promotions, and they have odds that are tough to beat. That’s how they make their money (instead of charging a commission).

Here’s what to take away from this:

  • Keep in mind that there may be (hidden) fees. You should try to figure out what those are for all the sportsbooks you’re thinking about joining. Many of our reviews will share these details, provided they’re available from the sportsbook.
  • Even though exchanges will have better odds (on average), because of their business model they won’t offer all the unique markets you might see from a traditional sportsbook. Wikipedia gives the example that many exchanges won’t offer accumulators or unrestricted multiple parlay betting. Anything they do offer is limited in number and type.
  • Traditional sportsbooks may run on thinner margins (less fees), but their profits have to come from somewhere. And that may come at the expense of offering promotions or having easier-to-beat odds.
There is give and take, or pros and cons, with either kind of sportsbook. You have to decide if finding the sportsbook with the best odds/lines is the best thing for you, or if there’s something better or something that you’d rather have (like a bonus or something).

Betting Promotions That Give Better Odds

Our recommended betting sites with high odds have another huge advantage that improves your returns. They often offer promotions that give even better prices!

Let’s take a look at them, so you know how to take full advantage of every edge available.

Best Odds Guaranteed

The classic best odds guaranteed offers usually apply to horse and greyhounds racing. The concept behind this promotion is simple and revolves around the so-called “starting price”. It represents the odds for every contestant at the start of the race.

If you have placed a wager earlier and the starting price is higher, your initial bet will be paid out at the higher odds.

For example, if you back a Horse A two days before the race at the odds of +100 and the starting price is +120, the latter counts if you win. It’s a nice way to boost your returns.

Reduced Juice

This promotion is mostly available in the USA and the name pretty much explains the logic behind it. The bookmakers simply offer odds and lines that come with a smaller margin. Let’s explore an example to make it clear.

The odds for the totals market for most NFL games are usually -110 for the under and -110 for the over which equals around 4.5% margin. If the sportsbook decided to launch a reduced juice promo, that would improve the odds to -105 and -105 which is about 2.5%.

The difference might look small, but just imagine how it impacts your profits over a large sample size!

Price Boosters and Enhanced Odds

You might see this promotion under the name “Price Boosters” or “Enhanced Odds”. Both mean the same thing and you probably know what to expect already. The betting sites will sometimes just boost or enhance the odds for a certain market.

They normally do it for more obscure outcomes, but it’s possible that some of the main options are included as well. You should certainly keep your eyes open for such deals, as they often deliver excellent value.

There’s another variation of this promo that deserves a mention and it’s called Acca Boosters. If you decide to place some form of an accumulator or parlay with this deal active, the sportsbook will give you a percentage-based bonus on your returns that rises with every selection.

Be careful, though, because adding selections that have no positive value would ruin the wager and the promotion can’t help stop that.

Best Odds Doesn’t Always Equal the Best Sites

Looking for the best odds available is important and even mandatory if you are serious about sports betting. However, you shouldn’t focus only on the prices. There are other factors at play that we always consider when we are conducting our list of top sportsbooks.

There’s no point in getting the highest odds if the bookmaker has no intention to pay! That’s why we also explore the following key factors.

  • Gambling license and security measures
  • Bonuses and promotions
  • Variety of betting markets

We want to make sure that our readers will be safe if they decide to join one of our recommended betting sites which is why we check the gambling license and security measures in place. We expect to see the latest SSL encryptions, a sensible privacy policy, and the backing of a respected regulator.

The other factors are important because they improve the value you get for your money. More markets means more opportunities to find a good wager and more bonuses means extra cash. Essentially, the promotions improve the prices further.

All of our top-rated betting sites with high odds have passed our tests with flying colors.

On top of the criteria above, they also come with several other advantages, including the following.

  • Fast payouts
  • A smooth mobile version
  • Intuitive user interface
  • Competent customer support

You can expect to get your money fast and there’s always someone to help if you have any questions. On top of that, using the services of our top sportsbooks online is easy on every single platform, including mobile phones and tablets.


Chances are that you stopped by this page to find the sportsbooks that offer the best odds or lines. But you probably didn’t expect to learn that it doesn’t always come down to that – there are other things you need to think about.

For example:

  • The sportsbook – what you pay pales in comparison to the importance of a reputable and trustworthy sportsbook.
  • The types of bets you’re making – such as point spreads – and how they compare to each other at multiple sportsbooks, often alongside straight bets.
  • If a sportsbook has dual lines, or if they have discounted lines, reduced juice or hidden fees.
  • If there’s anything else other than cheaper lines you care about. These may not have a direct impact on what you pay, but they can add or takeaway from your profits in some other way.

Like anything else sportsbook-related, this can get as complicated as you want. Most people reading this will probably do just fine choosing one or two of the sportsbooks we’ve found to consistently offer the best lines.

For everyone else, hopefully the information above gave you something else to think about, and above all will help you to make a little bit more money betting on sports.
