Best Betting By Sport

The list above shows you the best bookmakers overall, ranked according to our user ratings. But in some cases, you need more specific recommendations. For example, if you mainly gamble on one particular sport such as football, you might not need all the other betting options that are available. In that case, a more specialist site might give you a better betting experience. We constantly evaluate all of the new online bookmakers, as well as the more traditional UK high street brands, and evaluate them on an individual basis for each of the most popular sports. So no matter what you’re interested in, we can help you make the perfect choice.


Considering it’s the most popular sport in the UK and worldwide, it’s no surprise that just about every online bookmaker has football betting odds. You can bet on the big matches from the Premier League and Champions league, as well as events in different competitions from all over the world.

But all football betting sites are definitely not all the same. You’ll find that the best bookies have great odds, live betting, a wide range of fantastic bonuses and loads of great features. Others simply don’t.

So how do you avoid joining a poor site and make sure you open an account with one of the good ones? It’s simple. You just need to read this guide…

Horse Racing

No other sport is more synonymous with gambling, and people have been enjoying a day out at the racetrack for well over a century. But if you join the wrong betting site, you could end up being short-changed. Nobody should have to settle for a second rate service. So to get the best odds, most generous offers, and the most comprehensive coverage, you need to be very careful and make sure you’re betting at only the best online bookmakers.

We’ve crunched the numbers, and thoroughly tested every bookmaker on the web. So if you really want to find the top online bookies, check out our guide to the best horse racing betting sites…


Tennis is one of the most popular sports for punters. There are matches nearly every day and tournaments that run all year round. Odds can fluctuate with every point scored, which makes it particularly suited to in-play betting. If you know what to look for, it can be very profitable.

What you need is an online bookie that offers fast live odds, and a choice of in-play markets. In some cases, you can also watch the games live for free. Find out which betting sites have these features by reading our guide…


There are loads of different ways to bet on golf, and if you choose the right betting site, you can get some very big odds as well. Some bookmakers provide a wide choice of different betting markets. There’s no need to limit yourself to just trying to pick the player that will win a tournament outright. There are also 2-ball, 3-ball and mythical markets on every round, and these can provide some great opportunities to profit.

There are a few online bookies that are great for golf, and plenty more that aren’t worth bothering with. To discover which ones you should join, read more here…

Greyhound Racing

Everyone loves a night at the dogs. It’s another sport that goes hand in hand with gambling and remains very popular with punters today. You’ll still see the traditional turf accountants at the track, but these days you can get much better odds online at established and new bookies.

However, some smaller sportsbooks don’t publish odds on the dogs at all. Even some of the bigger sites don’t have a particularly good service. But others put a lot of emphasis on the dogs markets, and they even add live streaming and special offers as well. To find the best online bookmakers for greyhound betting, you need to read our greyhound betting guide…


Not many other sports can rival the buzz and excitement of boxing on a big fight night. Punters obviously love it too, as there’s always plenty of money changing hands at online bookmakers and exchanges.

But obviously, you want to know the easiest way to maximise your winnings. That means you need to know which bookies have the best betting offers, the widest choice of markets, and the highest odds. Read our guide now to find out more…


Cricket is a sport that has seen huge changes in recent years. The popularity of T20 and the huge sums of money in the IPL has attracted new fans to the game, and it’s also thrown up a lot more opportunities for gamblers. The short forms of the game are particularly well suited to in-play punters, and the best bookmakers should give you access to all the odds and markets you need.

We’ve revealed which bookies are best for cricket betting, so make sure you check out our guide…


If you’re a snooker fan, you’ll know that it’s one of the hardest sports to find a top bookmaker for. Many sites simply ignore snooker, obviously believing it’s not popular enough with punters. But that isn’t actually true, in fact, there’s always a lot of money involved when the big tournaments come along, especially in the later stages.

Luckily, there are a few betting sites that do offer a good snooker service. You can find out which ones they are here…
