The Top Online Gambling Sites

What's the big deal about gambling online? Well, in this day and age, it can be pretty tough finding your way to a land-based casino - much less having the time to actually do so.

Logging into a gambling site is a great little timesaver for those of who enjoy the thrills and spills of casinos in general. With online gambling sites, you're free to pick and choose the times it suits you to play - and then stop and walk away when you're ready. It’s much easier, quicker (and some even say more fun) than standard in-house casino gaming.

Gambling Sites vs In-House Gambling

We know that the atmosphere of a casino is part of the attraction - but it's undeniable that the other half (if not more) of the fun lies in the potential of winning big! With the best gambling sites, the chances to win are perhaps even better - yes, there’s still a house edge, but without all of the razzmatazz, the pressure to keep spending from excited onlookers and the ability to literally walk away and stop with the click of a button, it’s an all-around more focused online gambling experience.

And that’s not all - as gambling websites have lower overheads than land-based casinos, they tend to pass on these savings to the players themselves! Each of the top ten gambling sites listed above has a reputation for generosity, with excellent welcome bonuses, not to mention ongoing bonuses and promotions - the likes of which you're not going to see in land-based casinos.

Choosing the Top Gambling Sites to Play At

Maybe you're ready to get started with playing the best online gambling UK has to offer. That’s great! Now, how do you go about choosing a site to play at?

Here are just a few things you should consider when looking at UK gambling sites:

  • The welcome bonus - Check out the terms and conditions of these, including how much money you're actually getting, as well as any wagering requirements for cashing out or any game restrictions.

  • The ongoing bonuses and promotions - The same as the above; make sure you know what you're getting yourself into before actually committing to a bonus only to find out it wasn’t what you thought it was later.

  • The range of games on offer - It's all very well and good if you have everything else in place for a top UK gambling experience, but what if there’s nothing that you enjoy playing on offer? The best online gambling websites will have a plethora of games for you to choose from, as well as several different types of games - slots (and the various subdivisions of these), table games and even a live casino.

  • A range of payment methods - Unless you can actually play for real money, you aren't going to keep your winnings - so having a range of payment methods for both deposits and withdrawals is a top priority when choosing an online gambling site.

  • A secure, safe site - When dealing with your financial information and personal details, you want to make sure your gambling site is protected and takes your security seriously. Look for the padlock and ‘secured’ note in the toolbar when on the casino’s payments page, and if you don't see it, don't enter your details.

  • A regulated UK site - If you're looking for the best UK gambling sites, then you need to make sure your chosen casino is UK-regulated - look for the ‘UKGC’ (UK Gambling Commission) logo in the footer for this info.

If you're looking for all of the above, hassle-free, then check out our list of the top 10 gambling sites you should be playing at.

The Best Online Gambling Apps and Mobile Sites

Top gambling sites don't just come in ‘one-size-fits-all’ desktop sites, either! Nowadays, we’re lucky enough to be living in a world which thinks mobile - both in the sense of being able to move around and literally to have access to everything from your mobile.

Some of the top gambling sites have absolutely solid gambling apps, available in all OS and super-optimised for your Android or iOS-powered device. Back in the ‘old’ days of desktop-only gambling, this would have been unthinkable; nowadays, however, you can have an absolutely seamless experience via a gambling website’s app, complete with all of the games you’d expect to see, deposit options and customer support.

If you're not so into apps but still want to enjoy the thrill of playing on your mobile, then pretty much all top gambling websites have a perfectly optimised mobile version too. Back in the day, these used to be a little shoddy, with barely any games to play - and the ones that did were very slow to load and crashed pretty much all the time. Luckily we've said goodbye to all that, and mobile gambling is some of the best online gambling we've ever experienced - and it won’t eat your internet, either!

Play at the Top Ten Gambling Sites

But don't just take our word for it - go and enjoy the best online gambling apps and sites for yourself! Trust us, there’s nothing quite like the experience, and once you've got spinning and winning, you're likely to want even more of the good stuff!

Remember to gamble responsibly and have fun - with top gambling sites aplenty, we recommend trying out a few of the above list to find something which fits you perfectly. We’ve given you a great starting point to get through, and if nothing in the above list tickles your fancy, then you have the guidelines of what you should be looking for in any online casino you might choose to play at.

Otherwise, good luck and have fun - good gambling sites are worth their weight in gold, and could even bring you a fair bit of the good stuff in way of winnings, too!

"If you’re seeking out an established name in the gambling world for your next online casino site, you could scarcely hope for a finer example of the breed than William Hill; back when it was founded in 1934, it wasn’t even legal to gamble in Britain.
