At, we will help you find the perfect bookmaker

Deciding factors when comparing bookmakers are as follows:

1. Attractive Betting Odds

The most important point in a sports bookmaker comparison is attractive betting odds. Only this makes lucrative winning as well as ‘beating the house’ possible when betting on sports. Some bookies even put in best odds guaranteed offers, boosts and free bets. Free bets are the best way of getting more from your sports bets, but remember to read the terms and conditions of these deals carefully.

2. Extensive Betting Range

Even for those who enjoy football betting, there is still a need for an extensive range of betting options. After all, what is the sense of using a bookmaker who only offers a limited range of betting markets for a Premier League match, when there is the potential for odds on options like first goalscorer, corner betting and much more?

3. Generous Bet Limit Amount

No one likes being told that there is a limit to how much you can win with a sports bet. But this is what some sports betting providers do as they implement both a minimum as well as a maximum betting limit. Facts about this can usually be found in their betting rules sections, alongside information regarding how terms and conditions apply, 18+, GambleAware help and so on. Check out our list of betting sites without limits here.

4. Convenient Deposit Methods

High-quality online sports betting providers with many payment options. These can give you the chance to enjoy paying with a credit card to making bank transfers or even using payment providers such as PayPal, Neteller, Skrill or Paysafecard.

5. Quick and Easy Deposits and Cash-outs

Nobody wants to wait a long time to place their sports bets. So we will let you know which betting sites allow you to make instant deposits and speedy withdrawals. Only those sites that have a good track record of fast payouts will make our shortlist of the best sports betting sites.

6. Competitive Betting Bonus Codes

A betting bonus code makes it possible for a new player to get more from their sports bets quickly. These usually come in the form of free bets. Even a nice £10 free bet or even £30 free bets can work wonders with your wagering. We’ve seen bookies like William Hill and Betfred who have offers where if you bet £10, £30 of extra bets could be waiting for you. Sports fans who already have accounts with some of the 20 recommended top providers often take the additional bookmaker bonus codes for new and existing customers and use them as additional capital for their betting strategies. So if you want a bigger bet, new customers can usually get a lot more with these special offers. Just remember that even the best betting promotion often expires 7 days after signing up.

7. Transparent Bonus Conditions

Just as important as high betting bonus codes are transparent bonus code conditions. After all, what good are bookmaker bonus codes worth the equivalent of a £10 free bet or £30 free bets when the conditions to use them cannot be fulfilled? Most bonuses have important details regarding how terms and conditions apply, 18+, GambleAware help and more, and it’s well worth reading this before you sign up to these deals. Don’t forget that best odds guaranteed offers have important small print that needs to be completely understood so that customers deposit £10 easily to claim the deals. Even if you don’t understand the details of the bonus bet, a new customer can always get help from the bookie’s customer support team who will show you how if you bet £10, £30 of extra bets could be waiting for you. Be sure to check that the bonus doesn’t expire 7 days after signing up; otherwise you might be rushed.

8. Live Betting and Live Streams

As broadband speeds have improved, we’ve seen many online bookmakers take advantage of this trend by putting on live streaming for many top sports events. As a result, many of the top 20 best bookmakers found in the OpenOdds review will have this service that can be used for a more incisive in-play sports bet. In addition to this, we will also award extra points for those bookies who have the largest amount of live betting markets for the biggest range of sports from around the world.

9. User-friendly Website

Sports betting can be done practically anywhere nowadays, such as on your smartphone at a stadium, on a tablet at home, or just at a computer in the office. As a result, we will award maximum points to those user-friendly websites with speedy loading times and high mobile device compatibility. So if you are placing live bets, free bets or are calculating your free bet stakes, we’ll help you find those bookies that are easy to use.

10. Easily Accessible Customer Service

Did you have problems depositing or cashing out? Or is the live stream is not living up to your expectations? This is where the best online bookmakers gain their extra points with great customer service. This should be ideally in the English language and should be available 24/7, 365 days of the year via phone,  live chat or email. All of which should be able to help you with sports bets, free bets, withdrawing your free bet stakes and anything else.

Bookmaker comparison goes into the next round: Your vote counts

Only if online bookmakers fulfil all of these criteria will they be featured among the best sports bookmakers within our bookie comparison. At some of these bookies, if you bet £10, £10 in extra bets will be waiting for you. But at other gambling sites, if you wager £10, £30 free bets can boost your wagering profits. The following bookmakers have been put to the test for you so that you can who’s got the best offers. New customers deposit at one of the following sites:

888sport, Novibet, Betway, Bethard, Coral, Betfair, Genting, Bet365, MoPlay, STSBet, Mr Green, MobileBet, BetVictor, TonyBet, Grosvenor, Unibet, MansionBet, NordicBet and Paddy Power.

By betting experts for betting enthusiasts:

At OpenOdds, we have made it our mission to give you the best and most user-friendly online bookmaker comparison on the internet. If you go to some bookies’ sites and bet £10, £10 in extra bets will be offered to you, while at other places, if you bet £10, £30 free bets will be available. By coming to our comparison, you’ll see who’s being particularly generous with their new customers’ deposit bonuses.

By players for players:

At, there is already a very comprehensive comparison of the best sports bookmakers, and now we need your input. At some bookies, if you bet £10, £10 free bets will be available, and we want all betting fans to rate these kinds of bonuses. Most customers deposit £10 and then find that these bonuses are trickier than they anticipated. But with your help, we can make everything much easier to understand.

What personal experience have you gained with a specific bookmaker? Are they able to live up to the bold claims in their advertisements, or did they leave you wanting more? Your experienced input is of immense value and assistance to other players within the OpenOdds community. We are looking forward to your reviews! –> (Give Feedback)

Bookmakers in review: Five questions to consider

What are the newest trends in the bookmaker market?

Mobile sports betting with smartphones and tablets is one of the newest trends. Sports bookmakers using old-fashioned and mobile-incompatible websites will need to upgrade their services, or they will no longer cut the top 20 best online bookmaker comparison.

What is the best way to enjoy sports betting?

The most fun that can be had with sports betting is when there is no pressure to bring in the big profits. At some bookies, if you bet £10, £10 free bets will be deposited into your account which makes sports betting way more enjoyable when you focus on sports and competitions which interest you. Searching for the best value odds for golf or snooker bets can be hard to find, especially if you do not know your way around these kinds of sport.

Who are the best new sports bookmakers?

We are a bookmaker comparison site who feature reviews by betting experts, and we are always looking to hear about any promising new sports betting sites. If there is a new bookie that we should be aware of, then your suggestion might make it in the top 20 best sports bookmakers shortlist.

Who is the competitor: The sports bookmaker or other punters?

It’s usually a case of carefully examining the bookie’s odds and then anticipating what other punters will do. If one of the bookies on our shortlist has undervalued their bets, then you might be able to get in there first before other sports betting fans come along. But if you leave it too late, then the odds could get shorter, and your profits might not be so high. This is why it’s essential always to do an odds comparison test before you lay down your sports bets.

Is the best and most user-friendly bookmaker comparison?

The immediate feedback from OpenOdds readers is that we provide strong service, and we intend on keeping it that way. With your messages and feedback, your bookmaker experiences, and invaluable insider tips, you will remain one of the most exciting betting communities on the internet even better informed.
