How Do We Review and Rate the Best Slot Sites for UK Players

Introduction to the best slots sites UK

Explaining exactly what slot sites are – as the name suggests, they are basically online casinos that offer thousands of online slot games for you to play.

While some online gambling operators focus on table games or live dealer casino gaming, slots sites stock their portfolios with different types of popular slots titles from a huge range of software providers such as NetEnt.

This includes titles such as Starburst and Bonanza as well as new and exciting titles like Black Gold Megaways and The Expendables.

Welcome offers tend to be aimed at new players, so you will usually find a deposit bonus like a 200% casino bonus combined with free spins. In some cases, extra spins will not have any wagering requirements, either!

The most reputable online gambling operators will also provide loyalty schemes and VIP clubs to reward customers for playing at their website.

 

What is the best online slots game to win money?

What is the number one UK slots site

This is a question we are often asked, and the answer really depends on what you are looking for when choosing an online casino.

For the team at BestRatedSlotSites.co.uk, "the best slot sites are those that offer the widest range of software game providers".  

All the top slots sites will offer a generous welcome bonus with a low minimum deposit and no or low wagering casino bonus requirements.

Why play at online slot sites UK

If you love playing slot games, then you will love playing at top slot websites as they provide the best online experience to players.

What we enjoy about playing at the best slot sites UK is that most offer more than 1,000 different slot games, including video, jackpots and classic slots.

Each slot will offer something different from the volatility (how often it pays out and the size of the win) to the return to player and the bonus features and games available.

This means you can mix and match your slots play, switching from a three-reel classic slot to highly volatile video slots with a buy the bonus feature.

Top UK slot sites will also stock games from a huge selection of world-renowned providers including:

  • Big Time Gaming
  • NetEnt
  • Red Tiger
  • Microgaming
  • Thunderkick
  • Quickspin
  • Play’n GO
  • Pragmatic Play
  • Blurprint Gaming
  • NYX
  • Scientific Games
  • IGT
  • Fantasma Games

By packing their portfolios with a range of quality providers they can be sure their players can access the best slots UK meaning they have a fun and thrilling experience.

While the majority of great UK slots sites offer games from different developers, those that make the top 10 slot sites lists will also have exclusive and bespoke games.

This means slots launch at their casino before anywhere else, or that some of their games are only available at their UK slot site.

Regardless of whether the online slot site offers bespoke games or not, when playing at the best online slots sites you can expect to find slots with good payouts.

Online slots payouts explained

Online slots payouts explained

Online slot payouts, also known as the return to player, is the amount on average that a slot game pays back to players.

This is usually around 96%, which means that £96 out of every £100 wagered on the game on average is returned to players. This means that £4 from every £100 wagered is kept by the casino.

The payout of the online casino can also be worked out by calculating to total payout percentage of all games offered and dividing it by the total number of games.

Top UK slots sites will have a favourable average payout percentage, usually between 95% and 97%.

We only list top-rated casinos that have the best payout slots games for UK players. 

Best online slots for UK players

Best online slot sites (2020)

The top slots sites change all of the time as new gambling operators launch and existing websites update and improve the games and player experience offered.

The best slot sites online not only offer the widest range of slot games – including bespoke titles – but score highly across bonuses, payments, loyalty schemes and customer support.

The top slot sites will also hold a licence from the Gambling Commission, which means they are meeting the highest possible standards when it comes to responsible gambling.

It is actually against the law for gambling operators to accept players if they do not hold a UKGC licence. Of course, all of our recommended online slot sites do so you can be 100% sure they are reputable.

We have listed the best online slots sites in the UK. Our expert team of industry professionals have compared and reviewed Britain's top online slots websites.

Bonuses at the best slot sites

Bonuses at the best slot sites

When playing at online slots sites UK you will be offered a huge range of the best casino bonuses and promotions to encourage you to sign up and play at each site.

Top slot sites will also offer on-going rewards via loyalty schemes and VIP clubs to make sure you are rewarded for your play and continuing to wager with them.

These are some of the bonuses you will find at slots websites UK:

Welcome offer – this is usually a combination of a deposit bonus and free spins.

Deposit match bonus – this is where the casino matches your deposit up to a certain percentage.

Free spins – the casino allows you to play a number of spins without using your own cash.

Wager free spins – similar to free spins, they come with no wagering requirement on winnings.

Cashback – the casino gives you cash back on every bet you place, win or lose.

At a best slot site, you may also find no deposit bonus offers, which have become hugely popular with players in the UK and beyond.

A no deposit bonus is when the casino gives you a bonus – usually free cash or free spins – without you having to deposit any of your own money.

This means you can try the online casino, and some of the best online slots UK, and the casino will give you the bonus funds to do it.

Sound too good to be true? In some cases, it is.

No deposit bonuses usually come with strict terms and conditions, such as high wagering requirements and limits on max bet and max bonus wins.

Some of the top 10 slot sites UK do not offer no deposit bonuses, instead they offer bonuses with low or no wagering requirements.

For some players, these bonuses offer more value than other types of bonus offer as they provide a greater chance of keeping the winnings you earn from bonus cash and free spins.

Of course, if there are no wagering requirements in place, then you can keep all of your winnings without having to complete at playthrough requirement.

Wagering requirements at slot casino sites explained

Wagering requirements at slot casino sites explained

If you are new to playing UK slot sites, you may be unsure what wagering requirements, also known as playthrough requirements, are and how they work. Below, we tell you what you need to know.

A wagering requirement is the how many times over you must wager a bonus or winnings before they can be withdrawn as cash.

Wagering requirements at slot games sites are usually between x35 and x60, but at some slot sites UK it can be as high as x100 or more.  

Below is an example:

An online casino has a welcome offer of 50 free spins with a x60 wagering requirement imposed on any winnings you may accrue.

Free spins winnings would be considered as bonus cash, so you will have to wager your winnings 60x over before any remaining winnings can be withdrawn as cash.

So let’s say your welcome offer free spins winnings come to £10, you will have to wager £600 before your £10 winnings are released into your wagering account and can be withdrawn as cash.

Of course, in wagering the £600 to complete the playthrough requirement you may lose the £10 you won in the first place.

This is why it is important to read bonus terms and conditions before accepting an offer. While the best slot sites offer bonuses, they might not always add value to your play.

Casinos with the highest slot payouts

Casinos with the highest slot payouts

The best casino slots UK will have a favourable return to player, meaning the percentage of money wagered that is paid back to players is higher than with other slots and games. Not only do you want to choose a reputable casino that has high paying games, you also want to choose a fast payout casino so you can receive your winnings in a timely manner.

Most online slots have a return to player of around 96%, but some can be as low as 93% and some as high as 98% - to increase your chance of winning, make sure to play slots with a high RTP.

The RPT of slots at an online casino also impacts the overall pay-out percentage of the online casino, which is calculated by adding the RPT of all games and dividing by the total number of games.

A best slots website will usually have a page that provides the RPT of all of the games it offers, and the overall payout percentage of the casino. We have a dedicated section listing the best payout online casino UK sites for you to browse.

What to consider when choosing where to play top online slots UK

With so many slot sites available to players in the UK, deciding where to play can be tough.

That is why we review a wide range of online slot sites so you can learn everything there is to know about the casino before deciding whether to play there or not.

If you are new to playing slots at new casino sites, these are the most important factors to take into account when deciding which of our recommended sites to play at.

Games available – the casino should stock the best online UK slots, including titles from big name suppliers such as NetEnt, Red Tiger and Yggdrasil Gaming.

Bonus offers – consider whether the casino offers a generous welcome package and on-going promotions that add genuine value to your play.

Payment options  – Top 10 slots sites will offer players a range of payment options when it comes to depositing and withdrawing, so make sure your preferred method is available.

Licences – if you are playing from the UK, the online casino must hold a licence from the UK Gambling Commission. Of course, all of our recommended brands do.

Customer support – the best slots sites provide 5-star customer support via live chat, email and telephone with agents on hand 24/7 to assist you.

By reading our online casino reviews, and considering the factors mentioned above, you can have fun playing the top UK online slots at the best casino site for you.
