Best winning slot sites

Are you looking to find the best slot sites for winning? Then you want to take a look at the following casinos.

These slot sites have their average Return to Player value, or RTP, set very high, which is the key to winning.

RTP simply means how much money the casino pays back to the players after taking their cut. The higher the number, the more wins the casino hands out.

It is good to note that the slot site's RTP has much less impact on the result than the individual game's RTP. That being said, if the casino's number is high, it means that they have plenty of slots available with high return values.


Betway Casino

Betway Casino is a name that many online gamblers are familiar with, and there is a good reason for it. The site opened in 2006 and has been a big contender since day one.

This is an all-in-one site. They have slots, table games, live casino, sports betting and eSports betting all under one roof. The casino is also mobile-friendly and basically caters to all UK gamblers. It is no surprise that they have been doing well and being popular.

For players who are looking for the best slot site, Betway is a strong option. Their game library is large and has a ton of titles with high RTPs.

Betway starts you off with a bonus offer that comes with 100 bonus spins.

If you want a slot site that can be trusted and has shown it over a very long period, then Grosvenor Casino is the place for you.

Apart from their visual design, Casushi stands out due to their good slots that come with high RTPs. They have signed on some of the best game studios in the world. Even though they have plenty of games, they didn't just go for everything but the kitchen sink, they wanted to provide a quality library to their customers.

Casushi also shines in the way they treat their active customers. They have always had interesting reward programmes for loyal players.

How do we rank top slot sites

There are a ton of different online casinos, which makes picking one a difficult task if you aren't already experienced in online gambling. We do our best to review and rank the sites so that anyone can find a good place to play.

When we rank the slot sites UK market has on offer, we go over several categories and combine their results. To be the best slot site, a casino needs to be pretty much good at everything.

If a casino has specialised in something unique and narrow, it can still get a good score and a high rank. Then we just simply make it very clear to you what this particular site is good for and what it can and can't do. The best casinos for you might not always be the ones that are simply big.

Here are just some of the things we check and rate when we rank slot sites:

Why you should play at online slot websites

The short answer is that if you like slots, you should play on a site that specialises in providing you with the best possible slot experience. If you aren't going to play some of the games, then why pay any attention to them?

That being said, slot sites are designed so that players can enjoy the best online slots and that they have plenty of options when it comes to games. Players have their preferences when it comes to video slots, and a good slot site can accommodate them.

Choose a casino that gives you what you want

In addition to just having those slots, the best website for slots has bonuses, quality customer support, fast deposits and withdrawals, is mobile-friendly and easy to use, and above all, has a trustworthy casino license.

With so many options these days, it is good to play at a casino that fills the niche you are interested in. While older and bigger slot websites go for broad strokes, new casino sites often go for narrower and more specialised interests.

Is it safe to play at online slot sites?

As a general rule, if you play at a UKGC licensed slot site, you can rest assured that the casino is safe and fair.

To get a UK gambling license, a site must actively prove that it can follow the strict rules that the government sets. This includes external audits for the fairness of the games as well.

If the casinos won't do their part, they are quickly and heavily fined. If the issues aren't fixed, their gambling license will be revoked. This has happened to large gambling companies in the UK before, and it is a very clear threat to fraudulent businesses.

Playing on an unlicensed site poses risks. Some sites are perfectly fine and play fair, but if you do come across a casino that is a bad apple, you have basically no protection from them.

As you still have plenty of options, we do advise that you only play on UKGC licensed casinos just to be safe.

How to play in slot websites

You can easily play in slot websites. You don't need to have any prior experience, but knowing a few things will make staring even easier.

First thing you need to do is register an account. Just fill in your details and you are done. Then it is time to make a deposit.

When you make a deposit, you choose which method you want to use, then pick the sum and finally you confirm it through the chosen deposit method. Your options vary from debit cards to eWallets, from online bank transfers to mobile phone payments. Most are very straightforward and simple.

Your deposit might also trigger a bonus. These are promotional gifts from the casino and will give you additional funds or spins for a slot. Bonuses can be converted to real money, but they do come with terms and conditions, which you should read first.

Then it is just time to pick a game and go to town. If you win, then withdrawing your winnings is just like depositing money, but in reverse.

Below, you can see some of the more popular deposit options and how they work on slot websites.

Paypal slot sites

PayPal has become a household name as a trusted online payment method. So it was obvious that PayPal would make its way to online casinos as well.

Simply put, PayPal is perhaps the most trusted online deposit and withdrawal method. In the UK, there are plenty of PayPal slot sites to choose from. On this page alone, you can already find several casinos that accept PayPal.

PayPal is a mix between an eWallet and an online payment card. You can either store funds in your PayPal account which you then move to the casino, or connect it to a payment card where the money is taken when you use PayPal.

We have a guide available on using PayPal on online casinos. You can read more about playing on PayPal casinos.

Pay by mobile slot sites

Mobile gambling was a big, revolutionary thing a while ago. Back then casinos were duking it out and seeing who had the best service for mobile players. One of the key features was Pay by Mobile and the ability to make deposits easily on your phone.

Pay by Mobile slot sites make it much easier to play on the go. You don't need to go through the hassle of methods that are designed to be used on your desktop, but can easily and quickly deposit money with nothing but your phone.

All you need to do is make the deposit, provide a phone number and confirm that it was you who made the charge. The payment is made and you will see it in your next phone bill.

If you like to play while traveling or just prefer using your phone, then Pay by Phone slot sites are perfect for you. You can read more about Pay by Mobile casino sites on our dedicated page.

Neteller slot sites

When online gambling began to rise its head, eWallets were a very popular option to transfer money, and Neteller slot sites were a big deal back then. New methods have flooded the market since then, but Neteller still remains a popular option.

The big selling point of Neteller is the speed and security of the transfers. If you play on multiple slot sites, you can use Neteller to quickly move funds around and play where going is good.

Neteller is an eWallet, so you need to have an account and transfer money to it beforehand. Then when you want to deposit, you just choose your Neteller account and confirm that you want to move money from Neteller to the casino.

You can read more all about it on our Neteller casino sites page.

New slot sites in 2023

Players often like new things, which is why we keep an eye out for the best new slot sites. Though newer might not always mean better, they do come up with unique solutions and interesting ways of standing out from the crowd.

New slot websites might provide you with games that you don't see elsewhere, bonuses that are bigger or better than on established casinos, or they just do something that is so unique that you just have to see it for yourself.

Slot sites and responsible gambling

Gambling is always risky and the more you play, the likelier it is that you will lose. Even the best slot site is there to make money for its operators and not give it away.

The statistical outcome of every casino game is negative for the player. This means that with every spin, you come closer to eventually losing your money. It is important to understand the mathematics of gambling and to keep control.

Online gambling is a form of entertainment, and it should be treated as such. These games and sites are not there to fix any kind of financial issues. Play responsibly and stay in control.
