Today’s online gambling market is saturated with hundreds of casinos, making it difficult for players to decide which site is best for them. That’s why we set out to offer online casino players honest and unbiased reviews of the best online casino sites out there where you can play the best online slots, so you can easily determine which operators cater to your tastes and are worth your patronage.

How We Evaluate Online Casinos

Read on to find out what goes into researching our casino reviews, as our team works hard to make sure we get our readers all of the essential information they need to know.

Our Online Casino Review Criteria

There is no one-size-fits-all gaming site, and that is why we divide our reviews up into several sections. This helps our readers to pick out the key features that matter to them, so you can decide where you ultimately sign up based on the site’s:

  • Game collection
  • Bonuses and promotions
  • Banking
  • Customer support
  • Reputation

As you can see, the way we evaluate the top online casinos is not a quick job. It takes time to test and play on the site. Yes, we put money into an account and actually play to win. At the same time, we review the key features and discuss any areas where we may have differing viewpoints.

Online Casino Reviews

Honest and Unbiased Casino Reviews

The end result is an accurate review of the online casino that is honest and unbiased to give the reader a realistic expectation of what it would be like to play there. It takes time, but all of this is worth it if it brings value to you. Attention to detail makes our casino testing process such a success, which, in turn, allows you to make informed decisions on where to play your slots next.

Casino Licensing

Our casino reviews cover multiple features that all ensure the sites we recommend are safe and secure and carry out everything that is required when it comes to responsible gambling. Yet there is one check we perform before we even consider moving on to the checklist: the casino license.

All the casinos we review must be licensed by the UKGC; otherwise, we are not interested. The gaming site may be set up to operate in the UK, but without a UKGC license, the casino will never be recommended by Slots Temple. That is a cold hard fact that nobody moves on. Ever.

The Importance of a UKGC License

So, why is the UKGC license important to us and for all our readers? Let us explain. Ultimately, if an online casino company operates with a license, it means it has been approved by the gambling authorities within the UK.

Acquiring this license type is not a simple process, nor does it come cheap. Therefore, only the businesses ready to operate fairly and in line with the UKGC rules will be prepared to pay the licensing fee and go through the extensive license application process. In short, rogue companies will get found out before they can operate legally. The stringent rules surrounding the UK’s gambling environment are exactly why you don’t hear many stories about rogue casinos.

Keeping You Updated About UKGC Breaches

This is not to say that rogue casinos do not come about within the UK. Unfortunately, some casinos that get licensed end up on the wrong side of the rules and fall short of the high expectations of being a UKGC-licensed casino.

Don’t worry about this, though. Our team keeps on top of all the legal cases and ongoing sanctions, updating our reviews to ensure you always get the latest news and advice.

The UKGC is seen as one of the leading gambling authorities in the world, so you are in good hands when it comes to playing the best online casino games in the UK.

Player Protection and Security

The UKGC license is a good sign for everyone, but what exactly does it mean for you, the one who spends money and plays at these recommended online gaming sites? Again, let us pinpoint some of the biggest positives you can expect from these casinos.

Security is clearly a big factor here and one we have discussed already when it comes to any UKGC-licensed online gaming site. Player protection is also a big talking point that the UKGC takes very seriously. Cyber-attacks are a common issue in this day and age, and any online casino website without sufficient safeguards against such cyber-attacks will not be licensed. It’s as simple as that.

Other areas that you benefit from when playing at these sites include fair gaming and payouts, accountability and the freedom to file complaints against the actions of any licensed site, and the knowledge that your playing funds are protected.

Player funds are kept away from the casino’s operating costs, ensuring that players will always get their money back should any unforeseen situation happen to the casino.

Why Game Selection is Important at Online Casinos

The one reason we read reviews on the best casino sites, sign up, and then make deposits to our accounts is that we ultimately want to play casino games. So, it goes without saying that game selection at your next online casino is kind of a big deal.

Checking Out the Slots Selection

Players at online casinos should be given a great selection ofthe best online slots to choose from, and our favourites are those that have hundreds of games on offer. We like to see online casinos with a wide variety of jackpots, branded games, themed slots and unique formats.

As a site that caters to the interests of slots players, we always prioritise the slot selection at the online casinos review. It's important that they offer players a wide range of games to enjoy, while continuously adding new game releases.

Sites like Party Casino are a great example of this, as it not only features over 2000 slots; it also adds new slots daily:

Party Casino Slots Selection

Before signing up, make sure you use the search function to make sure your favourite games are available. This could mean a particular type of slot, such as Megaways slots or jackpot slots. Or it could mean checking to see if specific slot titles are included, such as Fishin Frenzy Megaways, or something as iconic as Starburst or Gonzo’s Quest.

You may even be someone who prefers to play the latest games, and in that case, you’ll be studying the new releases to see if that slots casino gets the most recent games in quickly.

Browsing the Game Selection

It’s also worth checking out the casino lobby design. If you’re the kind of player who likes to try new things, make sure there are plenty of filters and categories to make it easier for you to browse the best online slots out there.

Banking at Online Casinos

Banking is often overlooked by many casino players when searching for the best casino sites – that is, until they find themselves stuck at the cashier, as they look helplessly for a payment option they can access. Making these checks beforehand can make your time at the best online casino sites much easier in the long term.

Just a quick glance at the type of options you can use when depositing and withdrawing at your chosen UK slots casino means you spend less time signing up for random payment methods and more time using the methods you know and use regularly.

Popular Casino Banking Options

Banking methods such as Visa and MasterCard debit cards and playing at PayPal casinos are common. Other options such as Trustly, ApplePay, and Paysafecard are all popular methods that UK players continue to use when funding accounts and retrieving their winnings.

Payouts – Are Instant Withdrawal Casino Payouts Possible?

UKGC licensed casinos also tend to turn around transactions in reasonable time windows. Verifying your account will always speed up your banking, but you can expect near enough instant deposits and withdrawal times from anywhere between one and five working days at most sites.

Online Casino Payment Methods

Of course, we find that some casinos go above and beyond and send withdrawals flying out the same day, with some sites being hailed as instant withdrawal casino brands by offering Visa Fast Funds as a payout option. This is why we focus on this area in our reviews, and it’s why you should make the checks as well.

New Online Casinos

The UK’s best online casino scene is lucky to have such global brand powerhouses, from the likes of 888 Casino and Party Casino to Bet365 Games and Genesis Casino. Our team understand that it’s not all about these established brands, though. A new online casino can be just as exciting.

Players like to see what is new on the scene, and you can often find the latest site designs and promotion concepts at new online casino sites. These sites are doing all they can to promote their brand and build a loyal community of players who want to stick around. The best way to do that? Create a unique selling point and do things that the older casino brands aren’t. Easier said than done, but this is where our slots casino experts step in.

No Deposit Casinos

No deposit casino sites are a great way to get your casino adventure off to a flying start without actually putting down any of your own money. Sounds like the perfect casino, right?

Well, you will eventually need to make a deposit to continue playing. However, claiming a no deposit casino bonus can help to give you insight into a gaming site to make sure it’s the right one for you. You may find straight-up bonus money, bonus spins, or a mix of both maybe, and some sites may provide you with cashback based on the losses of your first session.

There is a big reason why no deposit casino gaming sites are big talking points, so be sure to check out our offers if you would rather “try before you buy” your next casino!

Generous Bonuses And Promotions

It's also a good sign when a casino rewards their customers for their patronage. So, we’re always excited to see when gaming sites provide plenty of great bonuses for players to choose from.

One of our favourite online casinos for bonuses is Playzee. The site features a new bonus every day and has an amazing loyalty program where Zee Points earn you impressive perks.

Playzee Daily Bonuses

We want to ensure that players are given the opportunity to play plenty of great slots as part of promotions, as well. So, when we review the best slots sites, we want to see bonuses are are focused on free spins and bonus leaderboards that give players the opportunity to play slots in order to claim offers.
