What Are Best Odds Guaranteed?
The core idea behind Best Odds Guaranteed (BOG) is that you are guaranteed the best odds to get the biggest returns from your successful bet. However, the specifics can be a touch more complicated, so you should note the following:
-
‘Best Odds Guaranteed' refers to the best odds that your betting site can possibly provide.
-
Pre-match odds fluctuate all the time before an event begins, which means that you get the best possible option out of those fluctuations.
-
It does not mean that if you were to place a bet on one outcome, and as the event goes on it becomes clear that the outcome is increasingly unlikely, that you can benefit from higher odds.
-
Bookmakers often begin this offer at different times. So, the promotion may only apply to bets placed after 9am on race day. In fact, there has been a recent trend of bookies changing their promotion to only count on the day of the race past a certain time. Check terms and conditions or ask customer service for details on the Best Odds Guaranteed times.
-
Some bookmakers have restrictions when it comes to multiples, and obviously betting limits still apply.
-
These promotions are generally found on horse racing, and sometimes greyhound racing.
For example: You bet on a horse on an early price of, say, 9/1 odds. But before the race begins, those odds change to 11/1. Because the latter represents longer odds, the payout is larger, and without Best Odds Guaranteed, you would simply have to accept the lower odds you initially went with. BOG means that even though you took the 9/1 odds, you still get the payout from the 11/1 odds.
The Best Bookmakers With Best Odds Guaranteed
To distinguish the bookies with the highest odds, I’m basing my recommendations on the following:
-
Diversity and quality of horse racing markets: I scrutinise the range and calibre of horse racing markets which incorporate this offer.
-
Overall standards as a horse racing betting site: While a BOG promotion can ensure you get the best odds, I also want to make sure you get the finest experience. That’s why when determining the premier online bookmakers with Best Odds Guaranteed horse racing markets, I’m also talking about the broader user experience
This means that you’re getting the largest variety of markets for more betting opportunities and a more interesting experience. The best odds bookies can also provide promotions that work alongside BOG for extra value, like extra places or enhanced ACCA odds.
Then there’s the usability of the site/app itself — whether it’s suitable for newcomers and reliable.
The rules for the promotion must also be transparent and competitive. For instance, while Best Odds Guaranteed offers are mostly consistent across bookmakers, some may offer different BOG starting times with anywhere from 8am to 1pm being common. The earlier the time, the better the offer.
With that in mind, here’s my pick for the tip top, cream of the BOG betting crop.
bet365 — For Consistent Excellence
What makes bet365 so special as a betting site is that they are such a steadfast all-rounder. Let's break it down below:
-
Wide Range of Betting Markets: bet365 offers an impressive variety of markets for horse racing, even for regular races, not just the big events. For example, a race at Sedgefield had over 180 different betting options, including unique bets like trifecta and tote markets, as well as each way extra odds.
-
Flexible Betting Options: You can place bets in various ways, such as betting on a horse not to place or betting without considering the favorite. This adds excitement to races with uneven line-ups.
-
Consistently High Odds: While bet365's Best Odds Guaranteed mainly applies to UK and Irish markets, they offer some of the best odds. For instance, they had better odds for the favorite in a Tramore race compared to other bookies. In this example, the favourite to win the 15:30 race was Where’s My Jet, for which bet365 provided odds of 1/5. Matchbook and Betfair offered them at shorter odds of 2/9.
-
Coverage of Smaller Events: bet365 also covers smaller events at courses like Musselburgh, Thurles, and Taunton, keeping you engaged with the sport throughout the year.
-
User-Friendly Platform: bet365's platform is known for being easy to use, both on mobile and desktop. The betting process is streamlined, allowing you to easily switch between different types of bets and view potential returns.
-
Customisable Bets: The Bet Builder and Cash Out features, including Partial Cash Out, give you more control over your bets, letting you tailor them to your desired risk level.
When you take all the above into account, you end up with a well-rounded betting site that not only has a strong focus on horse racing, but also provides a mix of good odds, wide market coverage, and user-friendly features, making it a top choice for both casual and serious bettors!
Highlights
-
Comprehensive UK and Irish race coverage
-
Broad stake limits

BetVictor — A World-Class User Experience
At BetVictor, user experience takes center stage, making this operator an often-overlooked gem amongst the best online bookies. Let's take a closer look at what this platform has to offer.
-
Exceptional Customer Service: BetVictor's customer support is available 24/7, providing quick and informed responses to any queries. This level of support ensures a hassle-free experience. They provided me with comprehensive answers on any question I had at any time of day, by an informed team who always responded within minutes. With such support, it’s hard to imagine ever feeling lost.
-
Attractive Betting Promotions: The site offers various sports betting promotions, including a Horse Racing Welcome Offer. Also, their "Run For Your Money" offer gives a cash refund if your horse loses at the start of a race.
-
Generous Odds: BetVictor's Best Odds Guaranteed (BOG) promotion, which is accessible with just a £1 stake, provides great odds across numerous markets.
-
User-Friendly Website: The website is easy to navigate, perfect for both beginners and experienced bettors. With a low minimum deposit of just £5, it’s accessible to a wide range of users.

Coral — An Abundance of Extras
If Coral were to rest on their laurels as one of the most trusted betting sites in the UK, they would probably maintain a strong user-base.
-
Consistently excellent odds backed by the Coral Best Odds Guaranteed is but one example of their exceptional standards. At Coral, the best possible is their baseline, including great margins on betting odds and excellent live betting odds.
-
Additionally, having the top odds goes further when there’s such immense coverage of races (both pre-match and live) covered throughout the UK and Ireland, including varied and creative specials plus a comprehensive “Build Your Bet” feature.
-
And it’s far from the only promotion available at Coral. Further enhancing your online gaming experience is a plethora of exciting betting promotions alongside best odds 100+ markets.
-
These include all kinds of free bets, available for newcomers, even available as an in-play horse racing free bet, which makes it a perfect fit for Coral’s live streaming options. There’s also extra place offers, other odds related promos such as bet boosts and Racing Super Series, where you can win huge cash prizes for making several correct selections.

LeoVegas — The Surprise Stand-Out
LeoVegas provide fantastically competitive odds across dozens of sports and countless events, with their LeoVegas BOG offer being the ultimate example of their commitment to being a real contender amongst your better-known sports betting sites.
In fact, I view their experience as a casino as a plus point. The excellent design which makes the site such a breeze more broadly is on full display here, with detailed statistics and graphics to lay out the action in a user-friendly way.
And of course, the mobile accessibility via dedicated Android and iOS betting apps, round the clock customer support, transparent terms and excellent security features work just as well, whether you’re looking for a fast betslip settlement or just to spin the reels.
Moreover, the choice to do both is always there. Looking for a generous jack-of-all trades? LeoVegas is likely to surprise you as one of the best odds guaranteed bookies on the market right now.

The breadth of pre-match markets is truly comprehensive, both international and encompassing local races just as readily as the illustrious likes of the Grand National and Cheltenham.

Most Offered Sports With Best Odds Guaranteed
Horse Racing Best Odds Guaranteed
For Best Odds Guaranteed on horse racing, betting sites normally accept bets which have been placed on race day, while ante-post and in-race bets are not eligible for the promotion. Here, I suggest reading the BOG terms on the betting site of your choice to be sure of the details involved.
My top suggestion for horse racing BOG promotions would be bet365, BetVictor and Coral.
Greyhound Racing Best Odds Guaranteed
When it comes to greyhound racing, there are many betting sites which offer BOG. The way it works is just the same as Best Odds Guaranteed horse racing. If you happen to place an early bet on race day at 8/1 but the odds on that dog go up to 12/1 before the race, you are guaranteed to get the winnings just as if you placed your bet when the odds where the longest.
Some of the top betting sites to offer BOG on greyhound racing are bet365, Paddy Power, Coral, William Hill and Ladbrokes.

ThePuntersPage Final Say
Best Odds Guaranteed is a bonus no racing fans should miss out on. In fact, if horse racing is a key reason for you wanting to use a sportsbook, I would genuinely consider this to be a deal-breaker. Odds are the bettor’s bottom line when it comes to your potential winnings, meaning that there’s arguably no promotion as powerful as this — at least within its selected sports.
Best Odds Guaranteed FAQs
No operator can consistently be the bookmaker with the highest odds. However, if you look for the Best Odds Guaranteed promotion, you can rest assured that you are getting the best possible odds from that operator regardless of when you placed your bets.
Yes. If you think that a market offers a decent chance of return, then the higher the odds the better (higher meaning larger returns). There are, however, other considerations which can impact your potential winnings, such as stake limits and other odds related promos.
Reasons include recent performance of a runner, new information on the fitness of a horse, weather conditions, jockey changes or non-runner deductions. There’s also the impact of market sentiment. In other words, if a significant amount of people back a particular horse, the odds can adjust to reflect this. These are just some examples. Anything that could cause bookmakers to change their perception of the likelihood of an outcome can lead to a price change.
Whichever odds provide you with the greatest return are considered the best odds. Anything which provides what you believe to be a fair return, are good odds. You can also consider good odds to be those which contribute to a reasonable bookmaker’s margin on betting options. In other words, when you calculate all odds and convert them to a percentage, how much over 100% they come to. The closer that number is to 100, the better the odds.
The best way of ensuring you’re getting the best odds as often as possible, at least on UK and Irish races, is to only use operators which provide Best Odds Guaranteed and to check the terms and conditions for all the important details. You should also exclusively bet with those with a reputation as being among the best online bookies. Any of my recommendations on this page will fit the bill. You can even sign up to multiple betting sites without issue, to ensure you get the largest returns on as many races as possible.
While I don’t wish to attempt to read the minds of betting site executives, I believe the most likely reason they offer this promotion is to get you to choose them over the many, many other sportsbook options in such a fiercely competitive market.
Barring any limits on your account, you should be able to place as many BOG bets as you wish, both pre-match and live betting odds. In fact, such an offer should have no bearing on how often you are able to bet.
While best odds guaranteed is simple, be sure to check out the terms and conditions regarding things like maximum payouts, applicable betting markets and timeframes you can use the promotion in.
