Offering better than average odds on the most popular sports seems to be the latest fashion among top bookmakers. They make big claims and present themselves as the most generous in terms of enhanced odds, but which companies actually live up to the claims? Which ones can you trust and which ones are little more than false advertising? In this review, we look at the most prominent enhanced odds offers, specifically the brands, the different types of enhanced odds, accumulators, and even the all-important terms and conditions.
Here is a list of the best bookmakers we recommend for Enhanced Odds. Read our reviews, select the bookmaker you would like to bet with and click on the link to start betting.

Due to their straightforward nature and the obvious benefits they provide to both sides, enhanced odds have gained widespread popularity among both bookmakers and bettors. While most of the sites we recommend offer them, these three stand out from the crowd when it comes to top-notch enhanced odds deals.
Grosvenor Sports used to be one of the least desirable top tier bookmakers when it came to promotions. These days that's changing in a big way, and their Double the Odds offer for new players is leading the way.
Today you can literally double the odds on your very first sports bet by signing up. The maximum stake is £10, but otherwise this offer is extremely flexible. You can bet on any sport and any possible outcome, and you have 60 full days after signing up to choose your market. The only downside we could see is that Neteller and Skrill deposits aren't eligible for this deal.
Following on from this, Grosvenor Sports also have an Acca Boost offer. This will boost your odds on up to three 3+ selection multiples per week, with no minimum wagering requirements.
888sport does things a little differently for their new customer enhanced odds offer. Instead of giving you the chance to use your enhanced odds as you please at sign up, they actually have you use the promo code to get the enhanced odds on a very specific event. And there are windows that you have to sign up in, not to mention that you have to use the right promo code if you happen to be a customer of theirs.
Clearly, most players would prefer to be able to control how and when they use their boosts. However, what we gave up in terms of flexibility when we revamped our product was made up for by huge price increases across a wide range of our offerings.
For example, just before this article was written, Poland was scheduled to play England in a World Cup qualifier. On most betting sites, Poland were 5/1 to win. On 888sport, with that site's enhanced odds welcome offer, Poland were a ridiculous 33/1 to win. So a successful £10 bet would have returned £340 instead of the £60 that a successful bet at 5/1 would have returned.
Here William Hill follows the same pattern as 888sport, technically offering welcome offers that are more 'price boosts' than 'improved odds'. Once again, though, in exchange for ceding a bit of control to your bookmaker, you get some truly impressive prizes.
Similar to 888sport, William Hill has made increased odds available on certain types of bets in certain markets. You must place your bet within a certain time period (usually the two days before the event) and use the correct promotional code.
Cristiano Ronaldo is now set to make his second debut for Manchester United. William Hill has two separate deals for the event, one for Ronaldo to score first and one for him to score at any time. You can use promo code EPR50 to get the first deal and get ridiculous 50/1 odds on it happening. Alternatively, you can use EPR30 to get the second deal where you can back him to score at any time at 30/1. These are just a few of the many deals that are offered in the lead up to a big event, and it's certainly worth keeping an eye out to see if they apply to you.
Typically, a bookie establishes its price in a particular market based on three key factors. They are:
When odds are juiced, the third factor becomes more important than the other two. A sportsbook trying to juice a certain market is simply trying to get more bets on that market, for whatever reason. Hell, sometimes it could be as simple as a sportsbook trying to balance its books with more action on one side of a bet than the other.
The name itself tells you what enhanced odds means. Simply put, a sportsbook that offers enhanced odds is one that temporarily inflates the prices on certain bets. For example, let's say you want to place a bet on a horse race (we know how much you love them). If the market price is $6 for every $1 you bet that a particular horse will win (which is the price you would bet at if you were betting on a horse that was a massive underdog), in a few hours that same horse might be worth $8 for every $1 you bet on it.
Enhanced odds can technically apply to single selections. More often, however, they are applied to a multiple that the sportsbook has put together. This could be a same-game combo, or it could cover multiple matchups. Either way, the book is willing to risk paying out big, flashy winnings in exchange for getting bettors to place what are ultimately hard to win bets.
Some terms are associated with better odds, but most of the time they just limit how much you can win in these markets. But really, these are just terms that are good to know. In general, enhanced odds are extremely easy to use and make a lot of sense for players. And in terms of the clarity of the offer, the value is obvious.
Boosted Odds require the slightest, almost imperceptible changes to your normal betting behavior. But to be super clear, this is in no way a suggestion or guideline to follow. You can do whatever you want.
Below is a summary table of the main offers mentioned (Grosvenor Sports, 888sport, William Hill). The details are based on the article content - always check the official bookmaker's terms and conditions before betting.

To see if a raise is worth it, estimate the expected value (EV). Formula with decimal odds:
EV per £1: EV = p × d - 1
p — your probability estimate (0–1)d — decimal odds (e.g. 6.0 instead of 5/1)For stake £s: EV(£s) = s × (p × d - 1)
d = 1 + (numerator/denominator). Example: 5/1 → 6.0, 33/1 → 34.0.EV > 0, it’s positive expected value; if negative, avoid.| Parameter | Standard Odds | Boosted Odds |
|---|---|---|
| Fractional Odds | 5/1 | 33/1 |
| Decimal Odds d | 6.0 | 34.0 |
| Assumed Probability p | 0.05 (5%) | 0.05 (5%) |
| EV per £1 | -0.70 | +0.70 |
1/d).
If you have spent a lot of time in sports betting, you may have come across the term 'price boosts'. Price boosts are similar to offers of improved odds. They are used to increase the price of your bets. However, as you will see in the following section, price boosts and enhanced odds are not exactly the same thing.
For now, let’s take a quick look at the two main types of price boosts – singles, and multiples.
A price increase on a singles bet allows you to increase the odds on a specific singles market of your choice. If this is new to you, a singles bet means that only one outcome has to occur for your total bet to win. The most common type of singles bet is the Match Result or Match Winner market.
Like their single selection siblings, multiple price boosts work pretty much the same way. But they only apply to those good ol' multiple bets. That means you have to combine not one, not two, but at least three qualifying bets. And they all have to come in for your total wager to win.
Accumulators can consist of different selections, but they are still a single combined bet. Therefore, it is the total odds of your accumulator that receive a bonus, not the individual accumulator odds. Also, each-way bets - halfway bets between singles and accumulators - usually do not qualify for these bonuses.
The terms "price increase" and "improved odds" are often used interchangeably by players. It doesn't help that some bookmakers use them interchangeably. But there are definitely three key differences between the two offers, which we lay out below.
With enhanced odds, your sportsbook decides both the matchup and bet type on which the boost applies.
When you have a price increase, it gives you control over both the contest and the type of bet you're placing. But the catch is that the actual price increases are usually smaller if the book thinks you're using them to your advantage.
Offers with increased odds are usually found in multiples, sometimes with as few as two or as many as four or five picks. This selection obviously makes them riskier, but it also establishes that they are premium products. The alternative - offering cheap multiples, which is what a book would do if it were trying to make up for having raised prices on straight bets - isn't even an option anymore.
Conversely, when it comes to price increases, they can almost always be applied to straight bets. Such bets are much easier to win, but as you might expect, they pay out much less.
Enhanced odds markets are released daily by most bookmakers. These are often in the dozens and give you lots of choices. And remember, you can take as many of them as you want.
They don't raise prices very much. You might get one if you're lucky. Usually you have to earn them through other betting promotions. On some days, you may only be allowed to use one or two of them, even if you have earned them.
Increased prices and improved odds are powerful weapons, but they must be used wisely. Here are five tips on how to do just that.
All prospecting promos attached to betting sites come with terms and conditions that you must read before participating in the promo. Failure to do so can result (as it has for some folks I know personally) in not getting the expected bonanza for doing something that on the surface seems like a fun bet. Here are some impressively placed terms and conditions that can make or break the bets you are thinking of making with these sites.
There are various strategies that sports bettors use when it comes to placing accumulator bets, although some are certainly more successful than others. Here are some hints and tips to keep in mind when trying to place a winning accumulator...
Take a look at the table at the top of this article for an overview of the best betting platforms that offer boosted odds. Simply click on the link for the bookmaker of your choice to get started.
All sports get a boost in their odds during specials, with the most popular being Horse Racing, Football, Tennis, Boxing, NFL and Golf.
This text describes an alternative method of offering bonus places on horse races. When it comes to offering horse racing places, most bookmakers will offer odds of about 1/4 for a place, in which case their customers can expect a return on their investment about 25% of the time when betting on the top three finishers. However, some bookmakers offer a kind of each-way bonus, in which case the customer can expect a return closer to 50% of the time.
The quickest way to verify this is to select the promotions tab of your chosen bookmaker. This will display a comprehensive list of the various types of offers, deals and promotions they have available for sports betting.
This means that only winning bets are accepted in these markets. Each-way bets can be placed, but they may not be part of the deal that offers the better odds.
