You might notice that the sign up bonuses listed above are all given in British Pounds (GBP). The reason for this is pretty simple – we’re Brits ourselves and so tend to naturally be biased towards the UK (we also run a separate dedicated UK betting website which maintains a regularly updated list of the best UK bookmakers that may be of interest if you’re from Blighty).

Most of the betting sites we list on this site will, however, also accept customers from other, non-UK countries and many of them offer bonuses in other currencies – such as Euros or US Dollars. Having said this, the one country that has very limited options is the USA, where red tape and general bureaucracy often get in the way of betting online. At time of writing none of the betting sites we list currently accept customers from the USA.

Major Sporting Events

As well as providing guides to betting on various sports – such as the best betting sites for horse racing – we also offer detailed coverage of the bigger events in the sporting calendar. Each guide is updated throughout the event and in many cases also serves as an index of match or race previews.

For each event we provide tips and stats as well as the tournament rules, format and even a bit of history. You can find lists of these guides below, broken down by sport (although we also cover a few other events that don’t fit into any of the categories, such as the Super Bowl).

Betting Online Versus At A Local Bookmaker

In case you haven’t quick picked up the hint yet, we’re pretty big fans of betting online rather than doing it in person in a betting shop – assuming your country allows such activities, of course. There are many reasons for this, ranging from the sheer conveniene of doing it on your own time and wherever you like through to the value you get online.

So lets give you a quick run down of the top reasons to bet online:

1. The Odds – First and foremost, you’ll generally get better odds online compared to a brick and mortar bookie. Part of the reason for this is that the local bookmaker has additional costs – such as the rent on the shop and staffing costs – but there’s also less competition. The bookie knows that if you’re at his shop you’re unlikely to leave and walk 10 minutes down the road to a competitor if you don’t like his odds, wheras online you can quickly jump from site to site to find the best deal. Sometimes you’ll find better odds in a shop, particularly when a line is moving quickly and they’re slow to act, but on the whole we’ve found better prices online.

2. Convenience – By definition, placing a bet in person requires you to physically be there. This means leaving the comfort of your sofa or whatever bar you may be in and trundling off down the road. And if you win, you’ll have to go back to collect your winnings. In contrast, thanks to smartphones and tablets bets can be placed online from virtually anywhere – and yes, that includes the little boys room if you’re so inclined.

3. Betting Offers – Part and parcel of their being more competition online is that the betting sites will fall over themselves to get your custom. And this isn’t limited to beating each others odds – most sportsbooks also will offer you a welcome bonus when signing up which ranges from £10 all the way up to a massive £200, given in free bets in your account. Some of the bigger sites also run frequent (almost daily) promotions such as money back specials, enhanced odds and bonuses. And whilst some of the high street bookies do offer some of these promotions in store, in order to claim you’ll need to go back to the bookies with your slip, which also requires you to realise you’ve triggered an offer – meaning you could miss out if you forget or weren’t aware.

4. Live Betting – Most online bookmakers, or at least the decent ones, offer a wide array of in-play betting options on a variety of sports. So if you prefer the fast paced nature of betting on a match that’s happening right now, or simply want to hedge a losing bet, you will have a lot more opportunity to do it online.

5. Streaming – If you mainly head to the bookies so you can watch the 2:15 from Newmarket on their TV, you may want to lake a look into live streaming. Many betting sites offer streams of all UK and Irish horse and greyhound races, as well as racing from around the world. Plus, some even offer it on other sports such as tennis, cricket, basketball and international football.

In fact, the main advantage that the high street betting shops had over the online betting sites was the ability to immediately get your hands on your winnings in cash. However even this is a non-issue these days as many of the big UK names such as Coral, Ladbrokes and Betfred allow you to bet online but then collect your winnings from any of their shops.

Responsible Gambling

Before we proceed any further we wanted to bring up the subject of responsible betting. It’s important when participating in any kind of gambling activity to make sure you’re in control at all times – for the majority betting is a fun and entertaining pastime that adds an extra bit of excitement to a sporting event, but for some it can become a destructive habit.

As a general rule of thumb we recommend that you should only bet what you can afford to lose and never chase your losses. And if betting is making you unhappy, depressed or stressed then simply don’t do it – it’s supposed to be enjoyable so if you’re not enjoying it, don’t do it. In the words of the betting industry – ‘Take Time To Think’’.
