What Is Best Odds Guaranteed?

Best Odds Guaranteed (often shortened to BOG) is a horse and greyhound racing offer that pays your bet at the higher of the early price and the Starting Price (SP) if it wins. If the SP is shorter than the price you took, you keep the higher early price, so you always get the better of the two on winning bets.

It is usually applied to win and each-way bets on selected horse and greyhound races. It only improves returns on winning selections; losing bets are simply settled as losers with no change.

Example of Best Odds Guaranteed

  1. You backed a horse for £10 at odds of 4/1 earlier in the day on a race that has Best Odds Guaranteed.
  2. By the off, the horse has drifted, and its official Starting Price is 6/1, and the horse wins the race.
  3. Without BOG, you would be paid £40 profit (4 × £10). With BOG, the bet is settled at 6/1, so you receive £60 profit instead (6 × £10), plus your £10 stake back.

Check whether the race is covered by BOG before you bet, as not every bookie or race qualifies.

Best Odds Guaranteed Times

Best Odds Guaranteed (BOG) times are the hours on race day during which a bookmaker will apply BOG to your horse/greyhound bets, and these windows vary by bookie.

Many bookies switch BOG on from a set time (often the morning of the race) up until the off, and bets placed outside that window will not qualify. BOG doesn’t usually apply to ante-post bets, and some bookies only apply it to bets placed on the day.

Best Odds Guaranteed

How We Rate and List the Best Odds Guaranteed Bookmakers

We only list bookmakers licensed by the UK Gambling Commission, and we check each licence on the Commission’s public register. For BOG, we read the bookmaker’s terms, including:

  • Exclusions: races or offers where BOG doesn’t apply, such as extra place races
  • Coverage: which races and bet types qualify
  • Start time: when BOG starts applying on race day
  • Payout caps: the maximum extra you can win from BOG, per bet or per day

BOG Betting Markets

If you want to bet in the UK with the best odds guaranteed offers, you’ll likely only find bookies offering them across horse racing and greyhound racing events. In rare cases, you may find a sportsbook offering football bets as a promotional offer; these are usually very restrictive as they come with several terms and conditions. Enhanced odds are more common than BOG in football betting.

Best Odds Guaranteed Horse Racing

The best horse racing betting sites at Mr. Gamble regularly feature BOG promotions. UK horse racing is the core market for this promotional offer.

In UK and Irish horse racing, bookmakers publish prices before the race starts. A price you take on the day, before the off, is often called the early price (EP). With BOG offers, you can bet on the day of the race from the activation window on the odds that are shown, and be paid at the Starting Price if it’s bigger.

For example, you may take a horse at 4/1 after 10:00 GMT on race day. If its Starting Price is 6/1 and it wins, you’re paid at 6/1. Some bet types may be ineligible, as the promo applies only to win-only and each-way markets.

Best Odds Guaranteed Greyhounds

Another popular market at UK bookmakers that offers BOG is greyhound racing. It works in the same way as BOG on horse racing. You need to place a bet on the same day as the race and after the activation window to benefit from any odds that may drift before the race starts.

The best greyhound betting sites allow you to watch the biggest greyhound races through live streams and telecasts they have. It’s important to make sure you recognise and satisfy the terms and conditions, as these can vary at each sportsbook.

Best Odds Guaranteed Football

A best odds guaranteed bookie may offer the promotion for football betting. However, it's extremely rare and isn’t something new UK customers should always expect to see. The best betting sites may offer it on specific matches, but it’s important to recognise that this isn’t the norm. Enhanced odds and odds boosts are more common for football betting.

BOG Betting

Common Terms and Conditions for BOG Promotions

BOG promotions come with many common terms and conditions you must be aware of. These include:

  • Opening Time: “Opening Time” is when BOG starts applying on race day, e.g. from 8am, 9am, or 10am until the off, with any bets struck before that time not qualifying for BOG.
  • Bet Type: The “Bet Type” section states which bets qualify, typically fixed‑odds win and each‑way singles (and sometimes multiples) on UK/Irish horse or greyhound racing.
  • Cash Out: Most T&Cs state that bets fully or partially Cashed Out do not benefit from BOG, because the bet is settled early at the cash‑out value rather than the SP. This policy is standard across the best online betting sites with cash out.
  • Rule 4: The Rule 4 clause says standard non‑runner deductions still apply to your bet, and BOG is then applied to the post‑deduction price if the SP is higher.
  • Each‑Way Terms: Each‑way place terms (e.g., 1/5 odds, 3 places) are fixed by the race terms, and BOG only affects the win part of the bet unless explicitly stated otherwise.
  • Payout/Benefit Cap: A “maximum benefit” clause caps the extra BOG uplift per customer, per day, or per bet (for example, £1,000, £10,000 or £25,000 in additional winnings).
  • Minimum/Maximum Stake: Some betting sites specify minimum stakes (e.g., £1 win / 50p each‑way) and occasionally cap stakes on races or customers for which BOG is available.

Why Bet at Best Odds Guaranteed Betting Sites

Best Odds Guaranteed (BOG) means that when you back a horse early with a BOG bookmaker, your winning bet is always settled at the better of the price you took or the official Starting Price (SP). This turns price moves in your favour on winners without ever making them worse.

Odds move because money, information, and market sentiment change through the day: money arriving, going, or reacting to going changes, jockey switches, tip coverage, and trading. If you bet early at 4/1 and the horse drifts to 8/1, without BOG, you are stuck on 4/1 and effectively “sold” your winner too cheaply, but with BOG, you get paid at 8/1 instead.

Think of BOG as a built-in edge that only kicks in when the SP is bigger than your early price, while never hurting you when the SP is shorter. Examine the table below to visualise the value being offered when using BOG offers compared against when it isn’t being used in a simplified way:

ScenarioEP (Early Price)SP (Starting Price)Return on £10 stake (No BOG vs With BOG)
SP shorter than EP (no drift)4/13/1No BOG: £40 profit; With BOG: £40 profit (EP kept, SP ignored)
Small drift in your favour4/15/1No BOG: £40 profit; With BOG: £50 profit (extra £10 from BOG)
Bigger drift in your favour4/16/1No BOG: £40 profit; With BOG: £60 profit (extra £20 from BOG)
Large drift in your favour6/110/1No BOG: £40 profit. With BOG: £100 profit (extra £60)

Odds can appear in more complex forms (11/8, 4/6, 7/4, etc.), but using a betting odds calculator can help you to work out what odds are greater/shorter than those to see if you benefit from the promotion.

Why This Matters Long Term?

If you regularly bet on racing on the day, BOG means you won’t miss out when a winner’s SP is bigger than the price you took. It doesn’t change your chances of winning, and losing bets still lose.

Betting Promotions To Use When BOG Is Not Available

If BOG isn’t available as a promotion for a specific sports market that you want to bet on, it’s possible to find a different type of bonus that may be used. Some bonuses are more versatile and expansive compared to best odds guaranteed promotions, including the following…

Free Bets

Free bets are widely offered by bookies. You may find sites with betting apps with a sign up bonus that can be used to claim this promotion. 

A free bet lets you bet without staking your own money, but you usually have to deposit and place a qualifying bet at minimum odds first. Free bets are common at online football betting sites UK.

No Deposit Free Bets

A sportsbook free bet no deposit can be more difficult to find, but they are available. This works the same as a free bet offer, but without the requirement to deposit funds first.

Again, sports free bets are typically available across various sports and events; horse and greyhound racing (not alongside BOG) may be possible to wager on.

Enhanced Odds

Several bookies continue to offer punters enhanced bets odds when using their sportsbook. It’s a common promotion across many sports. Almost all sports can benefit from bet boosts, but they will be at the discretion of the bookmaker and whether they choose to inflate specific odds. You won’t often find odds boosts available on BOG races, but it can happen.

Acca

Acca free bets or acca insurance offers are widely available at many UK sportsbooks, with this bet type hugely popular with British punters. You can find the best acca insurance offers at Mr. Gamble; this offer usually refunds your stake as a free bet, up to a set amount, if one selection in a qualifying acca loses. Football betting tends to benefit more from this promotion than others.

Best Odds Guaranteed: Pros and Cons

Best Odds Guaranteed (BOG) mainly offers upside on winners by paying the better of the early price or SP, but it also comes with limits and restrictions that matter to regular bettors.

We advise you to check out the table of pros and cons below to determine whether BOG betting is right for you and your betting style:

ProsCons
Paid at the bigger SP when your winner driftsNo benefit on losing bets
You can bet on the day without missing out if the price driftsDoesn’t change your chances of winning
Usually applied automatically when the bet settlesCaps on extra winnings per bet or per day
Usually covers win and each-way bets on qualifying racesOften excludes some races, such as extra place races, and ante-post bets
Only applies from a set start time, and may need an opt-in

FAQs

What does Best Odds Guaranteed mean?

Best Odds Guaranteed (BOG) means that if you back a horse or greyhound at an Early Price and the Starting Price (SP) is bigger when the race goes off, a winning bet is paid at the higher SP instead of the lower price you took.

Which bookmakers offer BOG?

Many of the top UK betting sites offer BOG promotions to UK customers once you have registered a betting account with them. 

However, it’s important to note that each has its own specific terms and conditions. This can include the maximum payout, time conditions, and race exclusions.

What do SP and EP mean in betting?

SP stands for Starting Price, the official odds of a horse or dog at the moment the race begins. 

EP (Early Price) is the fixed price you pay before the event, typically earlier on the same day, rather than waiting for SP.

How many bets with BOG can I place with the same bookmaker at once?

Typically, there is no fixed limit on how many qualifying BOG bets you can place at once; as long as the race and bet type are covered, BOG is applied automatically to all those selections, subject to each bookmaker’s normal stake and payout caps.
