How We Ranked Best Betting Sites with Highest Odds

When choosing the best betting sites with high odds to recommend, we review each bookmaker across a number of parameters. In this section, we discuss those parameters:

Odds

Of course, when looking for high odds betting sites, we first review the quality of the odds. We look for offers such as Best Odds Guaranteed, odds boosts and special bets with enhanced odds.

Promotions and Bonuses

Another way to get good value for money from a best betting odds site is to take advantage of any bonuses and promotions that may be available. That is why we review all of the promotions available at high odds betting sites, to determine which are the best.

Website Quality

We know that you want to have a positive betting experience, which is why we review betting sites with high odds to determine which are the best in terms of usability and layout.

Betting Markets

We look for high odds betting sites that provide a wide range of different betting markets for a wide range of different sports, to enable you to have plenty of choice in what you place your bet on. We also look for features such as Bet Builders, that can enhance your betting experience.

Payment Methods

When reviewing betting sites with the best odds, we check the range of payment methods available for bettors to use to fund their accounts. The best high odds betting sites will offer a wide range of payment options, including debit cards, E-wallets such as PayPal, Skrill and Neteller, and prepaid payment methods such as PaySafeCard.

Customer Support

Customer support is something that bettors only tend to consider if and when they encounter a problem, and poor customer service can make a problem significantly worse. That is why we thoroughly review each betting site with the highest odds that we recommend, to check the number and quality of ways to contact customer support services.

What do High Odds Mean?

If you are betting for fun then high odds are not so important and although it is going to be better to have high than low it should not really make any difference to the amount of fun that you have. If you are betting to make a profit then odds are the only thing that matter, as long as you remember to factor in the effect bonuses and promotions will also have on true odds of your return. Nobody is psychic and attempting to only bet on things that will win is futile. It is far better to bet on things when the odds represent value (the return is greater than the probability) and this can mean betting on things you do not think will happen sometimes!

For example, if we were to pay £1 to roll a dice, and if it is 1/2/3/4 OR 5, I am paid £1.10. I am getting odds of 10/1 on, or Decimal 1.1 on that bet. I could bet on number 6 and get 10/1 against (Decimal 11). If you ask me what I think will happen, I think it will be a 1/2/3/4 or 5. If you ask me what I will bet on, it will be the 6, because that one is the value bet, and betting on that will over time show a profit, where as betting on the other option will in the long run be a loss.

How to Find the Best Betting Odds

When considering which betting site has the highest odds, there are a number of things to look for to find the best betting odds. We provide some tips, here:

Compare markets between bookmakers - When deciding on which bet to make, visit a few different betting sites and compare the odds that are on offer at each one, for each specific market. You will find that there are differences between the odds available, so choose the bookmaker that will give you the best value for money.
Consider more unusual bets - Often, more unusual bets carry better odds than the more obvious, popular markets, so don’t be afraid to choose something a little left field for your wager.
Look for enhanced odds - Many of the best high odds betting sites offer bet boosts, price boosts or enhanced odds on selected markets, so these are definitely worth considering.

Available Payment Methods

Here, we share the payment methods and limits available at our top five betting sites with best odds:

Bookmaker	Debit Card	PayPal	Neteller	paysafecard
Betfred	£5	£5	£5	£5
Quinnbet	£10/£2000	N/A	N/A	N/A
Star Sports	£1	N/A	N/A	N/A
888sport	£10/£3000	£10/£100	N/A	£10/£1000
Unibet	£5/£10,000	N/A	£5/£10,000	£10/£500

Enhancing the odds of a bet

Sometimes, not always, but sometimes certain bookmakers offer you the option to boost your bet odds. Sometimes this can be on absolutely any bet whatsoever, but more often it is restricted to being a specific sport. As well as this some bookmakers boost Acca bets when they reach a certain number of legs, and the more legs you add the great the odds are enhanced. These are two ways to enhance the odds of a bet.

Types of Sports Odds & How to Understand Different Formats

Fractional Odds

Fractional odds are the most common odds format that you will find at UK best odds betting sites. Fractional odds will usually look like this: 2/1, 4/1 or 15/8. Essentially, 2/1 means that for every £1 you bet, you will receive £2 back, plus your initial stake.

To calculate your potential profit, you can multiply your stake by the result of the first number divided by the second number. For example, if you stake £5 at odds of 4/1, calculate 5 x (4÷1) = a profit of £20.

Decimal Odds

Decimal odds are most commonly used outside of America and the UK. Decimal odds might look like 1.50, 3.25 or 6.00. The decimal number indicates your total return per £1 staked.

For example, if you were to bet £10 on 3.25, your return would be £32.50 (£10 initial stake plus £22.50 profit).

Moneyline/American Odds

American odds are - as they sound - most commonly found in the USA. American odds will usually be a positive or negative number, such as -150 or +320.

If the odds are a positive number, such as +320, this is how much profit you will receive if you stake $100. If the odds are a negative number, such as -150, this is how much money you will need to stake, in order to win $100.

How the Betting Sites Set Their Sports Odds

Every betting site is different and free to set their odds using any method they wish. It will vary from bookmaker to bookmaker and also probably from sport to sport and from market to market. It is likely that for some of the major sporting events they will have odds compilers able to make a tissue and offer their own odds. For other lesser sports and markets they will likely look at what the exchanges have priced it up as and copy that with a bigger margin. Then as bets start coming in each bookmaker will adjust the odds to balance their book as much as possible, and the fact that different bookmakers will have accepted different bets at any one time is part of the reason that they have differing odds.

Sports With High Odds Offers

The following sports regularly have high odds offers attached to them.

Best Odds Guaranteed:

Horse Racing
Greyhound Racing.

Enhanced Odds:

Football
Tennis
Baseball
American Football
Boxing
Cricket
Cycling

Best odds sites for Football

Football is the sport most wagered on by the UK public (if counted by the number of bets placed) and it stands to reason that all bookmakers compete to have the most attractive odds. Below we list our partner bookmakers who on average have the lowest margins but remember that promotional offers can adjust the true odds, and are something to also bear in mind, rather than just the raw data.

Bookmaker	Premier League	Championship	Serie A	La Liga
Matchbook Zero	99.8%	99.8%	99.2%	99.4%
Smarkets*	97.6%	97.4%	97.1%	97.3%
Unibet	96.1%	95.7%	94.2%	95.5%

*After taking commission into account.

Best odds sites for tennis

Betting on tennis is surprisingly popular, possibly due to the speed that the game can change and that when there are only two players taking part it is relatively simple to analyse. The odds that you can get are of course important and we list the best odds tennis bookmakers that we partner with below. We have used the combined Mens and Womens outright markets and list how often these bookmakers were best or joint best priced on the top ten players.

Bookmaker	Wimbledon	US Open	Aus Open	French Open
Betfred	11	N/A	3	4
Star Sports	6	6	3	1
BetUK	6	N/A	4	8

Best odds sites for horse racing

Horse racing odds are notorious for fluctuating on the day of the race, it is almost impossible to compare which are the best odds sites due to the fact Bookmaker A could be best one minute and Bookmaker B the next. As a rule on any horse other than the favourites then the exchanges will have the best odds by some distance. There are however factors such as being Best Odds Guaranteed, and if this is the case then your odds will always be the same as or higher than a non Best Odds Guaranteed price, assuming they both have the same Early Price.

Bookmaker	Best Odds Guarnteed
BoyleSports	From 8am Day of the Race
Star Sports	From 9am Day of the Race
Betgoodwin	From 10am Day of the Race

How to Get Best Odds Guaranteed

Usually, there is a process to follow in order to take advantage of Best Odds guaranteed promotions. We describe it, here:

First, create an account with your chosen bookmaker, which offers Best Odds Guaranteed.
Visit the promotions page, and find the Best Odds Guaranteed promotion. Read the Terms and Conditions carefully, as there may be certain stipulations that you must meet, such as placing your bet before or after a certain time, on the day of the race.
On this page, you should also find a list of the coming races that offer the Best Odds Guaranteed promotion.
Navigate to your desired Best Odds Guaranteed sports page, and select the race that you wish to bet on.
Make your selection, then enter your stake in the bet slip, which should pop up on the page. Occasionally, you may have to opt in to the Best Odds Guaranteed promotion on the best slip, but this is unusual.
Confirm your bet, and wait to see if it is successful.
If you win, and the starting price odds were higher than the odds at which you placed your bet, you will be paid out at the most favourable odds.

Conclusion

To sum up, if you are betting for pleasure and to enjoy the experience of watching a match or a race a little bit more then the odds do not really matter. If you are looking to make a long run profit however then they are the only thing that matters, everything else is just noise. You are better off trying to learn where to find better odds than you are trying to figure out which bets will win.

Frequently Asked Questions

How do sports betting odds work?

Sports betting odds are the representation of how much you will win (have returned) should your bet win. The less chance there is of something happening, the longer (or larger) the odds will be, because it happens less frequently you will win more when it does. If something is more likely to happen then the odds will be shorter (or lower) and you will win less when it happens.

Why do odds change?

Odds change because of many factors but the two most common, and most logical, reasons are that something has changed to make a particular outcome now be more likely than before.

A common example may be a football team the day before kick off is evens (Decimal 2) to win a match, but then on the morning of the game their star striker is ruled out because of an injury. Now without him the chances of them winning are not so great and therefore the bookmakers might raise the odds to 5/4 (Decimal 2.25) to reflect that.

The other reason can be that nothing has obviously changed but for whatever reason people are betting large amounts again and again on one outcome more than any other. This will leave the bookmakers with an uneven book and result in a loss if that event comes to pass. Generally bookmakers like to hedge their bets so as to have a profit on all different outcomes and so they will cut the odds on that one to discourage further wagers and they will raise odds on the other outcomes to encourage bets there.

How many different odds formats are there?

There are three major odds formats, that is ways to display what your odds are. Traditionally in the UK the most common way has always been fractions, this is where the first number spoken is the amount you will win for every second number you stake. The two numbers put together is your total return. For example 8/1 means you will win £8 profit for every £1 you stake, the total return from the bookmaker will be £90 if you win. More common these days is the European system of using Decimals. This would display 8/1 simply as 9. Nine is the total amount you get back and has already included the stake in this calculation, but 8/1 and Decimal 9 are exactly the same thing. It is possible, although very unlikely, that you might want to use US odds. These are quite simple when it is odds against because for example 2/1 is +200, 4/1 is +400, 5/1 is +500, etc etc. It is simple to just think if how many % you multiply your stake by. It gets a lot more confusing when it is odds on, because you may have -400. Now -400 is the inverse of +400, so 4/1 becomes 1/4, which is Decimal 1.25.

Our advice is that if you can use Decimal then do that because it is the quickest and simplest one to work out in your head.

How to find the best odds on the market?

Well this is a good question and there is not one over riding best way. You will find with experience which bookmakers offer the best odds on which sports, and then you can refine it still further to what bookmakers offer the best odds on either the favourites or underdogs for that sport, so that will be the first place to look. We provide lists of the best bookmakers on average on this site, but the best bookmaker for any one individual bet is a case of searching them all. You will also need some luck because just because the odds you see are the best at this time, wait a few hours and there could be better odds elsewhere. OR all odds are cut and you should have taken what you had. It is sensible to bet when the odds offer you value, but trying to find the BEST value possible is a fools errand.

What to Watch Out for With Best Odds Guaranteed?

Check carefully to see which date and time you need to place your bet by. Customers usually need to wait until the day of the race to place Best Odds Guaranteed bets.

What are Win Limits?

Win Limits are the maximum amount of money that a bookmaker will pay out in case of a win. For example, if your bet wins £500,000 but the bookmaker’s Win Limit is £100,000, you will be paid £100,000 and forfeit the remaining £400,000.

Is Best Odds Guaranteed Just for Horse Racing?

Best Odds Guaranteed is most often found on horse racing bets, but is also commonly found for greyhound racing and occasionally for other sports, too.

Which Bookie Has the Best Odds Guaranteed Offer?

Bet365 has great Best Odds Guaranteed offers for both horse racing and greyhound racing, as well as enhanced odds offers available for a variety of other sports markets.

Do Bookies Pay Best Odds Guaranteed?

Yes, bookies do pay Best Odds Guaranteed, provided that they have a Best Odds Guaranteed promotion running, and you meet all of the Terms and Conditions associated with it.

Why Do Betting Sites Offer Best Odds Guaranteed?

Betting sites offer Best Odds Guaranteed to provide punters with reassurance that they will receive a good value bet, and that the betting site offers better value to its customers than its competitors.
