The Best Slot Sites Online

The table above has been geo-targeted so that you can only see the best slot sites available to players in your country. We hope you enjoy the free spins bonuses and top slot games available. We’ve given each sites 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.

How We Select the Best Slot Sites

There are hundreds or perhaps thousands of UK slots 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 slots sites.

Gaming Licences – To make sure that everything is legal, safe, and fair, we only recommend slot sites 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 sites 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 slot 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 sexy 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 online slots sites listed here offer them. You could be entitled to free spins on Starburst or even bigger and better 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.
