The Best Online Slot Sites

The table above has been geo-targeted so that you can only see the slot casinos available to players in your country. We hope you enjoy the free spins bonuses and top slot games available. For example, some of these Cleopatra slot sites offer 20 free spins. We’ve given each site a review and star-rating based on our findings. You can read more in the reviews, or visit the sites yourself to find out first-hand what’s available. Don’t forget there are lots of freeroll slot tournaments to play in, too.

How We Select the Best Slot Sites

There are hundreds or perhaps thousands of UK sites out there. We’ve selected the above as the “best of class”, but how did we come up with this list? Why didn’t we include any of the hundreds of others which we could have? We have a quality control process to make sure that we only recommend the top slot websites.

Gaming Licences

To make sure that everything is legal, safe, and fair, we only recommend casinos with valid gaming licences. For UK players, that means a license from the UKGC. For players from elsewhere, it could mean a license from Gibraltar, Malta, or the Isle of Man. The best slot casinos play by the rules and aren’t afraid to allow iGaming regulators to audit their conduct. This is why we only recommend sites with valid licences.

Fairness

All of the sites we have listed host fair slot games from reputable gaming companies. Just as it’s not fair for you to cheat slot machines, it’s not fair for them to cheat you. We make sure that the games are provided by quality gaming companies and that you have a fair chance of winning.

Top Slots Games

There are too many slot games to count these days. We prefer games from respected software companies like NetEnt, Microgaming, IGT, Playtech, Yggdrasil, Quickspin, and Barcrest. Top slots such as Mega Fortune, Starburst, and Gladiator Jackpot are available the slot sites you see in the table above. There are lots of excellent bonus games and progressive jackpots to make your gaming experience world-class. We also find the best RTP slots, so you have the greatest chance of winning. We’ve even curated special lists of games by category, such as this list of real money slots.

Mobile-Friendly

Each of these slots websites have been tested on iPhones and other iOS devices as well as Android phones and tablets. You can download apps at some of them, but you can play on them all on mobile-responsive websites with no downloads required.

Bonuses

We know that slots players love free spins and no deposit bonuses. Most of the slot game sites listed here offer them. You could be entitled to free spins or even bigger and better slot bonuses. You can see the welcome bonuses available to new players above.

Payments

If you win a jackpot we don’t want you to have to wait for days or weeks to get it in dribs and drabs. We also don’t want you to have to pay excessive fees to withdraw. We carefully read the banking policies before recommending a slots site. The best slots sites don’t charge withdrawal fees, give you lots of ways to make deposits such as PayPal and Neteller, and pay you within hours.

What Slots Can I Play at the Top 10 Slot Sites?

We’ve been careful to ensure that the best online slots are available at the sites we have recommended. Some games you can play include these top 10 slots, although there are many thousands of games available.

  • Starburst

There are a lot of different payment methods available at the top slots sites. Commonly accepted payment methods include Visa, Mastercard, PayPal, Neteller, Skrill, Paysafecard, Boku Mobile Pay, and even Bitcoin. Of course, you don’t haver to deposit if you’re playing free slot machines.
