Everything You Need to Know About Online Casino Sites

Since the first online casino opened 23 years ago, online gaming has become a booming business. There are hundreds of online casino sites offering an array of games for desktop and mobile from online slots to roulette and blackjack. The sheer, ever-growing, number of online casinos can be overwhelming for new users. How do you separate the wheat from the chaff?

So, before you get started, take the time to look over our top casino sites rankings, read the reviews of our favourites, and use our comparison tool to find the exact features you need to choose the top casino sites.


When you go to a land-based casino you are usually overstimulated by all the bright lights, music and overall buzz. It's that kind of excitement which can't be replaced easily. Most online casinos aim to replicate this sensation, and many of them actually succeed.

At a land-based casino you may need to wait your turn to play a table game while other players place their bets or remove their winnings from previous hands. You might also get distracted by your fellow players. With online casinos the whole experience is much smoother. Simply choose the game you want to play and jump straight into action. Most games for desktop and mobile are played at your pace so there’s no waiting for someone else to bet, nor having someone else rush you to make your move.

In a land-based casino you may find it hard to locate your specific table game, or the minimum bet might be too high. At the best online casino sites you'll find hundreds of game variations at all stake levels, making it much easier to find exactly the one you want to play.


If want to avoid the distractions of a land-based casino but also don’t feel like playing blackjack online like a computer game, then you might find the live blackjack and live roulette tables offered by almost all top casino sites the perfect balance.

With live casinos you really feel part of the action. They do away with the slick computer graphics and replace them with live videos feed of a real dealer dealing you cards, or spinning a real roulette wheel. The whole experience and thrill is much more akin to that you'd feel at a real land-based casino, truly giving you the best of both worlds. all or our recommended casinos offer live casinos by one the best live dealer casinos - Evolution, Playtech and Microgaming


One huge advantage of playing at an online casino is the virtually unlimited space they have to offer every kind of game, at every possible stake. The best online casino sites have a huge selection of slot games for mobile and desktop, some similar to those you have seen in real casinos, whilst others take full advantage of the technology at hand and provide a smooth, enjoyable experience while utilizing advanced graphics, features and sound effects. Some of our top sites like LeoVegas, Casumo, Dunder and Videoslots offer in excess of 600+ different games 

In addition to a complete range of online slots, you can of course play familiar favourites like blackjack, baccarat, craps, roulette, keno and video poker games. In selecting and reviewing the best casino sites we breakdown the games offering of each casino. Is it a slots specialist? Does it focus more on table games? Can you find more exotic table games like Sic Bo or soft/arcade games? We also look into the software provider powering the casino so you know whether you're playing at a casino mainly powered by Playtech, Microgaming, Netent with all their accompanying pros and cons.


Most online gaming sites offer their own software which can be easily downloaded, giving you access to their virtual casino. The software is free and usually allows you to test the games with virtual money (without using real money). You also have the option to play directly from your browser with Instant Play, which is offered by almost all top casino sites. This is a real advantage if you want to have a quick session on a computer that’s not your own. Similarly, no self-respecting casino comes without companion apps for mobile phones and tablets, which means you’ll never be stuck for a way to play, wherever you happen to be!


The intense competition that exists between the hundreds of online casinos has led to the rise of the casino bonus as an easy way to attract new players. The best casino bonuses can be worth hundreds of pounds, so they’re a great way to boost your bankroll. It’s important to read all of the terms and conditions associated with your welcome bonus, though. All our reviewed casinos require you to make a deposit with your own money before you get access to your bonus, and you will also need to meet a wagering requirement before you’ll be able to withdraw any winnings.

Wagering refer to an amount you have to stake (usually a multiple of your bonus amount) before your bonus is unlocked. As you’d expect, the lower the wagering limit, the better. In addition, each game normally has different wagering requirements. Technically known as weighting contributions, slots bets typically receive 100% credit, while wagers on other games will range from 0% to 50%. The best deals give more credit to a wide selection of games as well as a long period in which to meet the wagering limit.

If a promo scores well in the above departments, it gets our seal of approval which we highlight in our individual reviews. Of course, it’s important to remember that online casino bonuses don’t simply involve cash. Bonus spins allow you to play slots for free. Anything you win from a spins promo will be converted into bonus cash and subject to the wagering conditions outlined above. Even though your max bet will be limited during the bonus spins (usually around £0.10), they are another great way to boost your bankroll.


If you don’t have secure payment options, your wins will count for nothing. In order for you to have an entertaining and profitable time online, a casino needs to have solid support and payment solutions. During our UK online casino reviews, we expect the top platforms to offer 24/7 support with at least one immediate response method (phone, live chat) offered. A presence on social media especially Twitter and gaming forums is also a sign of a proactive operator that’s willing to help.

Assuming a sufficient support system is in place, the top-rated casino sites will offer secure payment options from recognised payment processors. As a UK casino player, you should expect to see credit/debit card, eWallet and electronic voucher options, including: Paypal, Visa, MasterCard, Maestro, Skrill, Neteller, Entropay, Ukash, Paysafecard and Pay by Mobile services such as Boku.


In the UK, online casinos are 100% legal. In fact, the UK is technically known as a “white” market as opposed to a “black” (illegal) or “grey” (unclear). The reason online casino, poker, sports betting and bingo are now fully legal in the UK is because of policy change in late 2014. In a bid to regulate all forms of online betting, the government amended the 2005 Gambling Act to include internet-based operations.

As part of the new system, any operator wanting to serve UK players must have a valid license from the UK Gambling Commission (UKGC). In order to obtain a licence, companies must pay certain levies to the government, meet certain operating standards and ensure player protection is a top priority. For example, all UKGC licensed casinos will have SSL secured software, have independently tested games certified as fair and use segregated accounts to store and protect player funds.

Essentially, an online casino has to prove it’s safe, fair and working to offer entertainment and protection in equal measure. We only endorse UKGC licensed online casinos. We do this because it guarantees a high quality online betting experience. Indeed, the UKGC’s regulations are the most stringent in the world and that means any licensed operator has invested time and money into its product to ensure a solid level of service.
