Gala | 15 | ⭐⭐⭐⭐⭐ |
Poker is one of the most widely played games on the globe, but it’s often underrepresented at the leading casino sites.
This was true of the casino sites we reviewed, with the exception of Betway.
Betway mostly offers video poker games. However, one of the things that makes it so impressive for poker fans is that it has its own cardroom. This means that you can compete against your fellow players in real time.

Check out our top three sites for casino payouts and see if you can win some money when playing their great games.
Top casino site for live gambling: Mr Green
Credit: Mr Green
Live betting options is one of the most interesting categories we use to compare the top casino sites.
The reason for this is that it’s not simply about the number of games or their payouts – it’s about how realistic they are and how good they feel to play.
You may disagree with us, but we just feel like Mr Green gets its live casino games spot on.
The dealers are very professional, the gameplay is incredibly slick, and the overall feel of the games is very close to what you get from a real casino.
Top casino site for sports betting: Betway
Credit: Betway
Sports betting is an enormous part of gambling – billions of people bet on their favourite sports teams and players.
Deciding which casino sites offer gamblers the most could be a simple case of picking the one with the best odds. The problem with taking this approach is that odds change all of the time and a site may have the best odds today and the worst tomorrow.
Within reason, casino sites offer competitive odds and we think there’s another factor you should use to decide which one is best – the range of gambling options.
Credit: Max Pixel
When we looked for the casino site with the best sports betting options it took a long time to compare, contrast, and then decide between them all.
But we did decide on a winner: Betway.
Betway has so many great options that it has something for (pretty much) every sports betting fan.
An honourable mention goes to Football Index.
It’s not a casino site (so couldn’t compete against Betway and the other casino sites we love) but it offers a really interesting way of betting on sports – it’s a combination of football players and the stock market.
How we review the leading casino sites
Credit: Pixabay
Reviewing casino sites is something we take great care and pride in.
Just like you, we’re players who love testing ourselves on the best casino games and we expect the very best from the websites that we choose to invest our time and money in.
There are some key things that we look for when we’re reviewing casinos for you:
Bonuses
Games
Sports
Security
Payouts
We take all these things into consideration and more when we’re deciding which websites we think meet the high standards you expect when you’re gambling.
But most importantly, we also ask ourselves if we’ve had a good time and feel safe when using these gambling sites.
We’ve tried each and every one of the casino sites and we can confirm that they not only meet the standards you expect, but they also excel at them.
Why free spins matter when reviewing the top casino sites
Credit: Flickr
Free spins are a big money spinner for casino sites – pun, of course, intended.
Free spins can start gamblers off with credit in the bank, which they can use on slot machines. This means they don’t have to spend their own money to place a bet.
While the number of free spins you get from the finest casino sites is certainly appealing, you need to look a little deeper than this to see if you’re really getting a good offer.
The things you need to look out for include: if the free spins are for a specific game; if there’s an expiry date on them; and if you get them all at once (some are teased out over a few days).
Free spins are certainly an important factor in comparing the top casino sites, but they’re certainly not the only one we care about – if anything, they are what they are: a nice little bonus and nothing more.
How do I know what the payouts are at casino sites?
Credit: Wallpaper Flare
You can find out the payouts available at a casino site by looking for its RTP.
RTP is the amount of money that’s paid back to gamblers, over time, when they bet at casino sites and wager on specific games.
The way it works is like this: If a casino site has an RTP of 97% then it means that for every £100 spent, £97 is paid back to gamblers over time. This means that the site has a ‘house edge’ of 3% over its gamblers.
Credit: Wallpaper Flare
Now, before you get excited, RTP doesn’t mean that for every £100 you spend you’ll get £97 back. The reason for this is that it takes into account every gambler and every bet placed, and some people win big or lose big.
Each casino site has an overall RTP and each individual game has its own RTP (we cover the main games in the rest of this guide).
We recommend that you compare the RTP of the casino site you select and the game you play against rival options before you spend any money.
How do I pick a great casino site to bet at?
Credit: Pixabay
There’s so much for you to think about when selecting the casino site you’re going to place your bets at. There’s the games it offers, the bonuses it advertises, the payouts it offers, and lots more.
We understand this and it’s why we spend huge amounts of time playing the games, reading the T&Cs of the bonuses, and finding out the payouts at the top websites.
We have a robust reviews process that we’re proud of and reading our assessments of the best sites is a great way to pick a great one.
Credit: Wallpaper Flare
However, the most important thing is that you must know what you’re looking for.
Do you care most about bonuses, games, payouts, or something else?
Once you know the things that matter to you then you can read our reviews, find the sections you care about and decide which casinos meet your requirements.
We give you all the tools to pick a great casino, you just have to use them.
What are the key bonuses to look for at casino sites?
Credit: Wikimedia
Bonuses are one of the key parts of casino sites.
They give you the chance to earn some extra cash or casino credit to use when playing your favourite games, potentially allowing you to win some money.
These are the main casino bonuses you should look for:
Welcome bonuses
Free spins
No deposit bonuses
But you shouldn’t only keep an eye out for these rewards.
The very best casino sites offer ongoing and ad hoc promotions to their returning players. This means you should also check the VIP offering when you visit a gambling site.
Do casino sites allow card counting?
Credit: Wikimedia
Card counting is a blackjack tactic that is designed to help you make the right moves at the right times, increasing your chances of making winning bets.
While this isn’t outlawed by casino sites, it’s almost impossible to count cards when you’re playing online games of video blackjack.
However, it may be possible to count cards when you're playing live dealer blackjack games.
This is because live dealer games can allow you to see the action much more clearly, so it might be possible to keep a tally of the cards that have been dealt.
If you’re heading to one of the many great casino sites to play blackjack then you might want to check out the benefits of card counting.
Why you should play roulette at the best casino sites 
Credit: Wikimedia
Roulette is one of the most recognisable casino games, featuring in numerous games, TV shows, and films.
If roulette is the game you choose to compare casino sites against, then we recommend that you try out a few of the best roulette betting strategies.
While this won’t guarantee to increase your chances of winning, at worst it’ll mix up your gameplay and keep things interesting.
Why you should try poker games at casino sites
Credit: Pixabay
Poker is possibly the most popular card game on the planet
It’s a billion-pound industry with countless incredible events, celebrity players, and some great places to play it online.
Casino sites are among the most popular places to play poker and for the best ones to stand comparison to their rivals they need a great range of games.
It’s this point on games that’s so important when comparing casino sites for their poker offering. This is because poker is the casino game where gamblers have the most control over the outcome of events.
Credit: Wallpaper Flare
The reason players have more control in poker games is twofold.
Firstly, you play against other players. This takes away the house edge because the casino sites aren’t competing against you to win.
Secondly, skill matters a lot more in poker because the betting decisions you make during games are affected by your mastery of the game – not by the pull of a lever using an RNG (random number generator), like in slots.
There are many different types of poker and one thing we really recommend you do before you play is to get an understanding of the main types of the game – of course, Texas hold 'em is the most popular, but that doesn’t mean it’s the best type of poker for you
Licensing and legislation to look out for at casino sites
Credit: Flickr
The number of available betting options, range of games, bonus options, and level of payouts on offer aren’t the only things you need to look for in the top casino sites.
You also need to be certain that you’re betting at a safe casino site and that means comparing the licensing and legislation.
Having spent a lot of time looking at the most highly regarded casino sites, one thing is clear to us – you’re better off knowing the right licensing and legislation authorities to look out for than trying to compare casino sites directly.
For this reason, the top casino sites have all of the licensing and legislation authorities listed in their websites as a matter of course – if they didn’t they’d put themselves at a massive disadvantage.
With this in mind, these are the licensing and legislation authorities you need to look out for.
UK Gambling Commission
Credit: Gambling Commission
Any casino site that operates in the UK will be regulated by the UK gambling commission.
Government of Gibraltar

If a casino site is licensed in Gibraltar then you’ll find the logo of the Gibraltar government on its site.
Malta Gaming Authority

If a casino site is licensed in Malta then you’ll find the logo of the Malta Gaming Authority on its site.
Spelinspektionen
Credit: Spelinspektionen
If a casino site is licensed (or is able to operate) in Sweden then you’ll find the logo of Spelinspektionen (the Swedish Gambling Authority) on its site.
It’s not only the authorities that regulate casino sites you need to look for.
You also need to know that you’re using a casino site you can truly trust. It is therefore recommended that you check to see whether they have the logos of organisations that support responsible gambling.
GameCare
Credit: GamCare
GamCare is a UK-registered charity that helps people who believe they may be a problem gambler.
GAMSTOP

GAMSTOP is an organisation that allows you to self-exclude from casino sites. The idea of this is that you register your intent to self-exclude from a casino site for a set amount of time and during that period you’ll be blocked from gambling there.
