Best Handicap Betting Sites 2024 - Bet On Handicap Markets

Q: What is a handicap in betting?

A handicap is applied by bookmakers to make a betting market more even. So if Manchester City are big favourites to win, you could back them to win with a handicap of -2.5 goals, which would mean that they would need to win by a three goal margin.

Q: Why do we have handicap bets?

Many betting markets feature a very strong favourite, which have appropriately short odds. With handicap bets, the market is made more even, by the favourite being given a handicap to overcome. Handicaps also serve to reward punters that successfully predict a margin of a result.

Q: What’s the difference between European and Asian handicaps?

With European handicaps there can be draws. If you back Liverpool -2 and they win 2-0, the result of the bet is a draw. Asian handicaps employ half goals, so this can’t happen. So if you bet on Liverpool -1.5 and they won 2-0 the bet is a winner.

Q: How does full, half and quarter goal handicap betting work?

With a full line, a team is attributed a full number handicap such as -1 or -2, which means there can be a draw. Half goal handicaps see teams get -1.5, or -2.5, which makes a draw impossible. With quarter handicap betting you get both handicap paired, such as -1 and -1.5 and the stake is split between the two bets.

Q: What does +1 handicap mean?

In a football match, a team in a handicap market with +1, start the game with a goal advantage. So if West Ham are +1 and the game is draw, they will win the bet. If they lose by one goal, then the result of the bet will be a draw.

Q: Which sports are most popular for betting handicap markets?

Football is the most popular sport for betting and features a lot of handicap markets. Asian handicaps eliminate the possibility of a draw in football, which is a common result. Other sports where handicaps are common, are high scoring ones such as American football, basketball and rugby.

Q: What’s the difference between handicap and spread betting?

With spread betting, the bigger the margin of victory, the more money you will win and the more that you are wrong, then the more that you will lose. When betting with handicaps, you can only lose your stake and the most that you can win, is your stake multiplied by the odds.

What is Handicap Betting?

There may be some you wanting an explanation of what handicaps are. So if you’re looking for a handicap betting meaning, carry on reading.
>Handicaps are applied to even up a betting market that is considered one-sided. If there’s a big favourite that is widely expected to win, the odds will be very short and unattractive to punters. By applying an extra handicap and virtual deficit to the superior team that needs to be overcome, the odds can be made more even and enticing for customers.
This also works the other way. You can give outsiders and underdogs a positive handicap, like a pretend advantage in runs, points or goals, for them to hold on to. If they beat the favourites or lose the match, game or event by a smaller margin than is set in the bet, then you’ve got yourself a winner.
That’s really all there is to it, though it can look a little more complicated when you look at a handicap market for the first time. In the next section, we’re going to take you through an example.

How Does Handicap Betting Work?

We’re going to show you an example of a handicap market. If a bookmaker were handicap betting football and Manchester City were playing Ipswich Town in the FA Cup, the regular odds for a City win would be extremely short. You would need a handicap to get any value out of the market.
So, for example, Manchester City could be given a handicap of -2.5 goals, with Ipswich getting +2.5. That would mean that if you backed City, they would have to win the game by a three-goal margin, in order for the bet to be a winner. If you backed Ipswich with +2.5, for your bet to be a winner, they could either win the game, draw, lose by a one-goal margin, or lose by a two-goal margin.
You can hopefully see how such a handicap evens up the respective chances of the two teams and helps to make the prices in a market, become more attractive.

How We Rank Bookies with Handicap Betting Explained

Having seen our ranking of the best sites for handicap betting, you are probably wondering how we came to our conclusions. Here are some of the factors that we considered.

Range of Handicap Markets

When judging the sites in this category, naturally a lot came down to how many handicap markets were on offer. We were looking for handicaps to be available across a wide range of different sports, with plenty of variety in terms of the markets, with Asian handicaps present.
Odds

If you’re placing a bet, the very least that you will expect is that the odds are competitive. Our recommended bookies can be relied upon in this regard. We always recommend having a few bookmaker accounts set up, rather than just one, so you can check between the various prices and pick the sportsbook that offer the most value.
Features

Bet Builders will allow you to add handicap bets to your selections, while Cash Out enables you to bank an early profit. Live streaming allows you to watch the action, at the same time as you’re placing bets. Most bookies provide mobile betting apps these days and many have tips sites, offering valuable insight.
Bonuses & Offers

When you sign up with a sportsbook, you’ll want a generous welcome offer, that give you some extra money to use with your new account. Offers for existing customers are just as, if not more important. The bookies that really excel in this area, give a lot of extra value to their users.
Safety & Security

Opening a bookmaker account involves giving your personal information, adding a payment method and depositing some money. Put simply, you are putting a lot of trust in the bookie. We make sure that our recommended choices are all fully licensed with regulatory gambling bodies, who ensure that your details and money are safe.

Most Popular Sports for Handicap Betting

In this section we’re going to explore some of the sports where betting on handicaps tends to be popular.

Football

The biggest sport at online bookmakers is football betting, and with good reason. It’s the most popular sport in the world and this extends to betting. You’ll find that football is at the front and centre of the homepages of most bookmakers, so you’ll have no trouble tracking down the match that you want to bet on.
Football handicap betting accounts for a fairly large portion of the markets that are available on any match. There are a lot of leagues where one or two teams are really dominant and win a lot of matches easily, so handicaps are a great way of making things more even.
The English top flight is famed for being a competition where the smaller teams can spring upsets, for all Manchester City keep winning it and yet, Premier League handicap betting remains very popular. Betting on the margin of victory in football, is a great way to get some extra value.

Rugby

Handicaps are common in rugby union betting. In fact, it is fair to say that it tends to be more popular than the match winner market. While the margins of victory in football tend to be slim, in rugby they are generally larger, so handicaps make sense. The sport of rugby has two codes. Rugby union handicap betting is given more prominence by bookmakers.
The annual Six Nations Championship is a hugely popular event, expanding throughout its history from just the Four Nations to include France and Italy. There are many other international and domestic rugby union competitions that attract a lot of interest from punters.
Rugby league handicap betting is not quite so popular, but the sport still has a very strong following in areas such as the north of England and Australia, where it is popular. The Super League is the major domestic competition for the UK, with the NRL being the equivalent in Australia. Among the markets on show, rugby league betting with handicaps is popular as teams like Leeds Rhinos, St Helens and Wigan Warriors have enjoyed periods of dominance in this code of the sport.

Tennis

Tennis is a staple at online bookmakers. It’s a sport with a year-round schedule, which produces matches on a daily basis, with ATP and WTA tournaments generally starting on a Monday and ending on a Sunday.
Along with the flow of regular tournaments, tennis betting and the sport’s annual calendar punctuated by major events. The biggest events on the tennis schedule are the Grand Slams, which comprise of the Australian Open, French Open, Wimbledon and US Open. In the UK, Wimbledon is a particularly popular when it comes to betting, with lots of promotions available based around the event.
Tennis handicap betting is a useful way for punters to gain some extra value. In the early rounds of tournaments especially, there can be some very short-priced favourites. So in such instances, you might back the likes of Novak Djokovic with -1.5 sets, meaning that he would have to win a match in straight sets or 3-1. There are also handicaps available for games, so you could back Djokovic with -9.5 games, for example.

Basketball

There are few sports that can compete with basketball betting for producing high-scoring encounters. It’s a slam dunk! Consequently, basketball handicap betting tends to be more popular than simply betting on the result.
Betting on the margin of victory, is a way to get more favourable odds. So for example, in the NBA, you could bet on the Golden State Warriors with a handicap of -7.5 points, to beat the Boston Celtics. That would mean that the Warriors would need to win by eight points or more, in order for the bet to be successful.
In the UK, the majority of basketball bets are placed on the NBA in America, which is the top competition in the world. However, there is also the British Basketball League and also lots of thriving basketball leagues across Europe, Asia and elsewhere. So even when the NBA is out of season, there are plenty of opportunities to bet on basketball.

Asian Handicap Betting

A type of handicaps that you may have heard mentioned is Asian handicap betting. The ‘Asian’ part of the name, comes from the fact that this sort of handicap originated in Indonesia. They are used in sports where a draw is a possibility, with the intention of eliminating the possibility of a stalemate result.
The Asian handicap bet is especially popular in football. So say Liverpool are plating Everton. In a regular market, there is the possibility of a Liverpool win, an Everton win or a draw. An Asian handicap takes the draw out of the equation. So Liverpool would start with -1.5 goals and Everton would have +1.5.
Obviously, it is impossible for a team to score half a goal, so there can be no tied result. Liverpool need to win by a two-goal margin for a bet on them to be a winner. If they only win by a single goal, then Everton are the winner in the handicap market, as is the case if the match is drawn, or Everton win.
You may have seen Asian handicap markets where a team has two handicaps. These are sometimes referred to as ‘Quarter goal handicaps’. So Manchester City say, might have handicaps of -2.5 and -2. In such an instance, your bet is split evenly between the two handicaps. A £20 bet would see £10 go on Manchester City -2.5 and £10 on Manchester City -2.
In this example, if Manchester City win by three goals or more, both parts of the bet win. If they win by two goals, the -2.5 part of the bet loses, but the -2 is a draw and that half of your stake is refunded. If Manchester City only win by one goal, or draw, or lose, then both parts of the bet are losers.

Pros & Cons of Betting on Handicaps

As tends to be the case with most things, there are both positives and negatives with handicaps. Below, we have highlighted some of the pros and cons.

Pros:

Helps to make uneven markets, more even
Gives punters extra value, with higher odds
Rewards being able to predict margin of victory
Adds variety to a betting event

Cons:

Not always available on all sports
Confusing for beginner bettors

Standard Betting vs. Handicap Markets

We’ve talked a lot about handicap markets. So is it better than traditional betting? In our experts’ opinion, it all depends on the event in question.
If two teams or competitors are well-matched, such as when betting on Six Nations title matches, then there’s an argument that there’s no need to place a handicap bet. The regular result market will provide strong odds and by trying to be specific regarding the margin of victory, you are adding a level of complexity to the bet, that makes a loss more likely.
On the other hand, if there’s a strong favourite, there is often very little point in placing a bet on the straight result. It’s only with handicap markets, that some value can be delivered to the customer.

Top Offers on Handicap Betting Sites

There are many bonuses and promotions, both for new and existing customers, that can be used in conjunction with handicaps. Here are some of the best betting offers and deals that you can enjoy.

Acca Bonus – The more selections you add to your acca, the bigger the potential percentage bonus on your winnings.
Acca Clubs – Place regular acca bets and these clubs reward you with free acca bets to use.
Cashback Deals – These offers give you a percentage rebate on any losses that you might think.
Deposit Bonuses – Available for some welcome offers and sometimes for existing customers, you get a percentage bonus on your deposit.
Enhanced Odds – The prices of certain markets are boosted beyond the normal level that would be expected.
Free Bets – This is the most common type of welcome deal and free bets are often available for existing users. To qualify, you generally you place a bet for a certain amount and in return you get a free bet.
Insurance Deals – Bookmakers can offer insurance on accas if only one leg lets you down, or if certain conditions in a contest are met, such as a football game ending 0-0. You get your stake back, normally in the form of a free bet.
Risk-Free Bets – As the name suggests, this is a bet without risk. Sometimes given as a welcome offer, you place a bet in which your stake will be returned, if it’s a loser.

Best Mobile Apps for Betting on Handicaps

All of our recommended bookmakers for handicaps have dedicated mobile apps for iOS and Android devices. This gives you the option of placing handicap bets, wherever you are.
You can access your betting account via a mobile browser, but we would always suggest using an app instead. They tend to be more secure, faster and are designed specifically for the dimensions of the smaller screen.
All of the handicap markets that you would find on the regular betting site of an online bookmaker, will be available on the app. When it comes to recommending a particular bookie for their betting app, we would point you in the direction of BoyleSports.

Handicap Betting Tips

In this section we are going to give you a few tips that should help when placing bets on handicaps.

Tip 1: Do Your Research

With handicaps you are not just betting on a result, but also the margin of the result. It’s therefore important that you do your research. So if you were football handicap betting, you would want to look into team news, home/away records, xG and goal records.

Tip 2: Consider the Outsider

People often tend to look at the favourites with handicap markets and it’s obvious why. They’re often very likely to win, so betting on them with a handicap gives the price a boost. However, there can often be just as much value in betting on the outsider. They may lose the contest, but if they can keep things close then they could win the bet. Look out for selections that keep things competitive in defeat.

Tip 3: Think About Motivation

For a selection to win by a big amount, they often have to be motivated to do so. For example, a football team that has already won their league, or a side guaranteed of a mid-table finish, have nothing left to play for and may have mentally switched off. In contrast, a poor team that are in danger of relegation, will be putting in maximum effort.

Tip 4: Compare With Other Markets

Look between handicaps and other similar markets, to see which has the best price. So if you’re considering betting on a football team to with a handicap of -1.5, it may be worth seeing what the odds are for that team to win and for there to be over 2.5 goals, or for the side to win half-time/full-time.

Tip 5: Give Yourself the Best Chance

Every little advantage that you can give yourself will be a help. So if you’re going to bet on a handicap market, make sure that you get the best odds, which you can do by opening a few betting accounts and comparing prices. Also, lots of handicap bets will be compatible with promotions and bonuses, so take advantage of those too, when you can.

Tip 6: Consider Expected Goals

Before looking at the handicap betting odds, it’s worth looking at the xG in football stats for a game. These give you an idea of how many goals a team should be scoring and conceding in a match. You can then pick the right handicap market accordingly based on this data. Although you can’t and shouldn’t solely rely on it, this can help inform any betting decisions.

Conclusion

We hope that you enjoyed our guide to handicap betting. As you will have seen, there are a lot of quality sports betting sites available for betting on handicaps. In our review, it was BetUK that came out on top in this particular category.
