All 33 Best Odds Guaranteed Bookmakers
What Is Best Odds Guaranteed?
Best odds guaranteed in the most simplistic of terms, means your bet will be paid out at the higher available odds, if the selection drifts on the market prior to the start of the race.
Horse Racing markets across the UK and Ireland can easily be affected by a multitude of different things, such as non-runners, changes in "going" and even comments from trainers and jockeys, so when the odds change, Best Odds Guaranteed (BOG) is a great help for punters.
From around 8:00am each morning (times may differ), any bet placed ante-post on a race is covered by BOG.
How Best Odds Guaranteed Works
Best Odds Guaranteed provides the highest available odds to the punter, based on the timing of their initial bet and the starting price (the odds at the very start of the race)
Simply put, if you place a BOG bet at 4/1 and the starting price drifts to 7/1, the BOG offer will pay out at 7/1.
If the odds shorten to 2/1 between your initial bet and the start of the race, you will still be paid out at the original 4/1 odds you took, when placing your bet.
How B.O.G. Works
Betway is one of many bookmakers providing Best Odds Guaranteed
Remember, even if a bookie is offering BOG, you might still find better odds on another online betting site.
You should still shop around for the best fixed odds before locking in your wagers.
The 'guarantee' that you are being offered, is that you can take a price on the day of the race, and compare it to the starting price. Whichever odds are larger, you will be granted those odds if you win.
A horse or greyhound's starting price is the final price offered before a race starts.
You can make the most of best odds guaranteed betting promotions every day, including during the Cheltenham Festival or Grand National.
All best odds guaranteed betting offers should apply to both win and each way wagers.
Best Odds Guaranteed: Key Terms
When compared, every Best Odds Guaranteed promotion is quite similar, with some minor nuances between them, so its worth checking the small print of each BOG promotion to see if one is more suited to your betting needs than another.
Elements to consider, include:
Eligible Races
Usually, the bare minimum in terms of eligibility is all UK & Irish horse racing. Some bookies may also include all domestic greyhound racing, such as BetGoodwin, and in rare cases, international racing may also be a part of the betting offer, for events such as the Prix de l'Arc de Triomphe or Kentucky Derby.
Time of Day
Each betting site should specify what time your bet has to be placed from in order for it to qualify for best odds guaranteed. Of course, the earlier in the day the better, so that you can take the often valuable morning prices and be eligible for BOG. 8am onwards can be considered a good time, whereas 10am is less favourable. Bet365 allow you to place your bets the day before.
Multiples
If you like to place accas and other multiples, you want to use a betting site that offers best odds guaranteed on these types of wagers, which isn't always the case. Some might offer BOG on doubles and trebles but not Lucky 15's and other similar multiples, so be sure to check beforehand. Betfred offers BOG on Lucky 15s in shop only.
Maximum Winnings
This is only really relevant to high stakes players, but winnings from best odds guaranteed promotions are capped per bettor on a daily basis. TalkSPORT Bet's limit is £10,000 for instance
FAQ - Best Odds Guaranteed
What does best odds guaranteed mean?
Best odds guaranteed is a type of betting promotion that is offered to existing customers on betting sites.
It applies to horse and/or greyhound racing, and the premise of it is, you place a bet at fixed odds on a particular horse or dog and if the price is bigger at the start of the race, you get paid at the greater odds if it wins.
Which betting sites offer best odds guaranteed?
The majority of top UK betting sites offer Best Odds Guaranteed, and they are all listed on this page. Big hitters like Betfair and Bet365 have BOG, and so do new betting sites like BetGoodwin and CopyBet.
Is there best odds guaranteed for football?
No. While there are more football betting offers than there are for any other sport including racing, best odds guaranteed is not a football promotion. You can, however, find similar promos for football, such as top price guarantees.
From what time does best odds guaranteed apply?
This varies from bookie to bookie. Some allow you to place your bets the night before, whereas others might be from 8am on the day of the race, or perhaps later.
Is there best odds guaranteed on international racing?
Most best odds guaranteed promotions are for UK & Irish racing only, but there are some rare exceptions.
Are each-way bets eligible for best odds guaranteed?
Yes. You should check the terms and conditions of the best odds guaranteed promotion on your chosen betting site just to be sure, but they should all include both win and each-way wagers.
Is there a cap of maximum winnings?
Some bookmakers such as Paddy Power do cap the maximum amount of winnings (£50,000) that a player can claim via the Best Odds Guaranteed, although others such as Betfred do not have a maximum ceiling on this amount.
Are there exclusions to the offer?
Yes, players who use free bet stakes, do not qualify for the BOG promotion.
Which bookmaker offers the best odds guaranteed?
There is no single bookmaker that provides "the best" BOG promotion.
If you want to get on as early as possible, some bookies like BetGoodwin go live with BOG at 7:00am, but may not be able to match the odds provided by a larger bookmaker such as Bet365.
If you are someone who stakes larger amounts, then Betfred's lack of winning cap, may also appeal to you, moreso than other bookies.
Check T&Cs and find the brand that suits your needs.
What time does Bet365 offer best odds guaranteed?
Bet365's best odds guaranteed promotion, begins at 8:00am every morning.
Does 10Bet offer best odds guaranteed
Unfortunately, 10Bet does not provide BOG or a similar promotion, however, they do provide odds boost tokens and extra place races for users.
