Different Types of Online Sports Betting

Sports betting, much like everything else, has grown and evolved over the years. There’s a lot more variety in the types of betting experiences punters can have today.

We’ve put together a basic list of the essential things to know when it comes to choosing what type of betting you want to try. These are the most popular types of betting around nowadays:

Pre-Match Betting

Just like it says on the tin, pre-match betting happens before the match starts. This is probably the oldest and most well-known type of betting out there. Though, even pre-match betting is much more than it used to be.

Punters aren’t just restricted to betting on who will win or if a match will end in a draw. Today, online sports betting sites offer tons of betting markets on things that can happen throughout a match or race.

Live Betting

Live betting is sort of the opposite of pre-match betting. This is a fast-paced type of betting that happens during a match or race. Punters need to know a lot about the sport, as well as the particular event, to be able to react to shifting probabilities on the go.

The adrenaline-fuelled nature of how quickly live betting happens is very different to the calmer and more calculated pre-match betting. Odds shift constantly, and betting markets open and close as the match progresses.

Spread Betting

The most popular type of betting is fixed odds betting, where punters place bets against the house based on provided odds. Spread betting, however, is different.

Spread betting is similar to handicap betting, as modifiers are applied to every bet. While handicap betting still uses traditional odds, though, spread betting evens the odds out.

Bookmakers do this by offering a “spread” of match or event outcomes. This evens the odds of all the possible outcomes.

Payouts can be more difficult to calculate, though, and losses can be much bigger. For example, a bookie might offer a spread on a match between Liverpool and Manchester City. You place a £10 bet on Man. City to win.

If a Man. City win is worth 25 points, a draw is worth 10 points, and a loss is worth 0 points, and you’re given a price of 12.0, then a loss can cost you a lot more than your £10 stake. A win would be (25-12) x £10, which would be £130 return on your £10 stake.

A loss would be (12-0) x £10, meaning you’d lose £120, which is much more than just your £10 stake.

Betting Exchanges

A simpler alternative to traditional bookmaker betting is using a betting exchange. Instead of betting against the house, like with traditional betting, punters bet against each other.

Betting exchanges charge a small amount of commission on every bet, but even with this fee, punters can sometimes find odds at a much better price than with traditional bookmakers. As punters are betting against each other, a winning bet on an unlikely outcome can be a massive windfall.

Betting on a betting exchange involves backing and laying bets, as well as managing your liability. As you aren’t betting against the bookmaker, betting exchanges also give punters to opportunity to wager much higher stakes than are normally accepted with traditional betting.

The Most Popular Sports to Bet On

Plenty of new punters ask us questions like “what sports can I bet on?”. The answer is, almost all of them! When it comes to online sports betting in the UK, though, there are 5 sports, in particular, that lead the pack.

Most of the online sports betting in the UK is centered around football, horse racing, cricket, tennis, and golf. This is why betting sites focus on these so much, and there are so many promotions surrounding these sports.

⚽ Football

With Britain’s love for football being world-renowned, it’s no surprise there are more football bets than any other sport each year. Fans and punters alike are certainly spoiled for choice, too, as there are plenty of huge football tournaments each year.

For example, the Premier League and the Champions League draw in thousands of punters from the UK alone every season. If you’re a footie fan that is interested in getting into betting, then not only do we have a guide to football betting in general, but also pages for the biggest football events, including where to bet on those tournaments and tips on optimising your strategy!

🏇 Horse Racing

Another British classic, horse racing has been a major betting staple for decades. Races happen every day across the globe in places like Dubai, the UK, Australia, France, and the US.

Thanks to online sports betting, punters don’t need to spend a whole day at the tracks anymore to get in on some horse racing action. When it comes to serving the UK market, a bookmaker’s horse racing offerings can be the deciding factor in whether they thrive or fail.

Some of the biggest horse racing events of the year happen right here in the UK, and we’re home to some of the world’s most prestigious racing tracks. This is why we have betting guides for the biggest and best races, like the Grand National, the Royal Ascot, and the Cheltenham festival.

🏏 Cricket

Football may get the most global media attention today, but cricket is the original international hit. Thanks to the spread of the British Empire, cricket is played across the Commonwealth, with the first international matches being held all the way back in the 1700s.

Fans of cricket betting know all too well that cricket is one of the most diverse sports to bet on. Punters can place bets on test series months in advance, while others prefer to bet live and react to things as they unfold after the coin toss.

In fact, betting on cricket is largely responsible for England’s first gambling laws, with the 1664 gaming act becoming law as a direct response to the public’s cricket wagers. The biggest cricket betting events for today’s punters to keep an eye on are:

🎾 Tennis

Tennis is a huge draw for bettors, mainly due to the fact that there are so few players involved in a single match. This means there are fewer variables in play, making it easier for well-informed punters to make accurate predictions.

Tennis betting is seen as one of the core staples on betting sites, and we don’t know of any reputable bookies who neglect to feature the sport. If you’re new to tennis betting, we recommend starting with the larger tournaments, as it’s relatively easy to find statistics about different players and matchups. Our picks for the top Wimbledon bookies and the best French Open betting sites, in particular, are worth taking a look at to help you get a leg up over other punters.

⛳ Golf

Thanks to innovations in technology over the years, golf is much more of a spectator sport today than it used to be. While punters used to need to rely on commentators to keep track of what’s happening on the course, there are more cameras, better cameras, and GPS tracking today. Thanks to this, golf betting has exploded in popularity in recent years.

If you’re interested in getting started with golf betting, we recommend starting with the bigger tournaments, just like with tennis. There’s far more information about the golfers and the courses to be found for the huge events.

Depending on what time of year it is, starting with either the US Open (improve your US Open betting strategy here) or the Australian Open (expert tips for Australian Open betting here) would be a good idea, in our opinion.

Best Betting Sites by Sport

If you’re looking to bet on a particular sport, then you need to make sure that you choose a bookie that has a proven track record with that sport. It might sound odd, but some online sports betting sites can offer a top-notch experience for one sport, but woefully lag behind with another.

The table below contains what our experts believe are the best betting site for each sport. They looked at things like event coverage, sport-specific bonuses like the ones mentioned below, the quality of odds, the amount of betting markets available, and more.

Online Sports Betting Bonuses

Most of the online sports betting sites featured on our site offer punters bonuses of one sort or another. While we won’t go into too much detail about bookmakers' welcome bonuses on this page, lots of bookies have sport-specific or even event-specific promotions for their existing punters.

When it comes to promotions, the sports that usually get the most attention from UK betting sites are exactly the ones you’d expect: football and horse racing. Promotions for other sports are out there too, but if you’re betting in the UK, you’re a lot more likely to find football betting promotions or horse racing offers.

What Kind of Promotions are Most Common?

Generally speaking, most promotions are free bets offers, also known as bonus bets. This is great news for punters, as most of our top bookies have pretty favourable terms and conditions when it comes to free bets offers.

It’s considered to be pretty common for bookies to run promotions for huge tournaments, like the Premier League and the FIFA World Cup. Some bookies offer longer, more complex promotions with point systems, while others just offer a steady stream of match-specific free bet offers.

Betting Features

Online sports betting has changed the game. It used to be that punters would have go to their local bet shop, and were limited to those bookies who happened to be close by. Today, thanks to the internet, punters have a wider selection of bookies than ever before.

More than that, though, bookies have way more features to make betting either easier and more engaging. Here are our picks for best and most useful online sports betting features today:

Cash Out

Cashing out a bet is a great way to either minimise your losses or guarantee your profits. This feature allows punters to settle bets before they’re concluded in the event.

Punters who predict that their bet might go south at some point can ensure that they settle their bets before the outcome is concluded, and doing this can be a great way to reduce the amount of money lost on a bet. For example, instead of losing an entire £30 wager on a losing bet, cashing out early could mean getting £20 of that stake back and only suffering a loss of £10.

Eagle-eyed punters can also recognise when a bet that seemingly is going to be a winner has a chance of becoming a losing bet as matches and races unfold. A cash out at the right time can ensure that you still turn a profit on that bet, even if the outcome would have rendered it a losing bet later on in the match.

As we mention in our deep dive into the Cash Out feature, the only real downside to cashing out a bet early is that punters end up with lower winnings than they would have earned if the winning bet was settled naturally. However, plenty of punters have managed to use this feature to keep their bankrolls in the positive.

Live Streaming

We mentioned live betting in our look at different types of bets above, but the one feature that takes live online sports betting to the next level is being able to watch a live stream of the event while you bet.

As live betting is all about reacting to events as they unfold, it’s only natural that it’s easier to do so when you’re actually able to see what’s happening. This used to be a rare feature for bookies to offer their punters, but live streaming on betting sites is becoming more and more common each year. Bookmakers who offer live streaming are the best options for in-play betting aficionados.

The best part? Bookies don’t charge punters for live streams. This means that live streams on betting sites are free! Considering how expensive pay-per-view and cable TV services are, this is one feature that not only increases your chance for live betting success, but can save you money in other areas too!

Bet Builder

The bet builder feature that is quickly becoming standard across the online sports betting industry isn’t actually that new, but it’s a much more accessible than ever before. This feature allows punters to request odds for specific bets that may or may not already be listed on a betting site.

The main upside to this, other than being able to make custom bets, is that bookies tend to offer much better value on odds for requested bets. This is sometimes true even when requesting bets that are already listed on the bookie’s site, and is a great way to try and get more bang for your buck.

Betting Apps for Smartphones & Tablets

Not only did sports betting move online, but it’s also available pretty much anywhere that punters can get WIFI or mobile reception! The vast majority of the world’s internet traffic happens on smartphones today, and mostly through using installed apps. Much like everything else on the internet, online sports betting has become extremely mobile-friendly in the last few years.

Whether you have an iPhone or an Android device, the vast majority of bookies have either a native smartphone app or a fully mobile-compatible website for you to build your bet slips from wherever you happen to be. Some of our in-house experts actually do most of their betting on the train home from the office!

Our Online Sports Betting Guides

Here at Sportsbetting24 we’re committed to making online sports betting more transparent and easier to understand. Because of this, we have detailed betting guides for almost every sport that can be wagered on.

What Do our Betting Guides Cover?

Our betting guides are all a bit different, as each sport is different, but they all have a few things in common.
