Our pick of the best online casinos UK

Much like Canadian casino players, UK casino players have a huge variety of different casinos to pick from.

Depending on which UK casino sites you visit can depend on what online and mobile gambling experience you get.

You can trust some casinos more than others, but whatever you do, make sure you find ones licensed by the UK Gambling Commission to ensure that they are looking after their players as best they can.

Our best casinos online for the UK below do just that. They take your security seriously not only when depositing and withdrawing but also while you’re playing.

Not only that, but they offer 24/7 customer support, a huge array of slot games from Video Slots to Megaways Slots to massive progressive Jackpot slots where you could win millions.

If you’re after a new UK casino to play some of your favourite games, then check out our list below:

  1. Videoslots Casino – best overall casino
  2. Grand Mondial Casino – best Microgaming casino
  3. LeoVegas Casino – best mobile casino
  4. Rizk Casino – best for promotions
  5. Casumo Casino – best for fun

1. Videoslots Casino – best casino site overall

Videoslots Casino

Videoslots casino has one of the largest selections of casino games online. Since they started in 2011, their goal has been to add the most software providers and casino games to give their players one of the best choices of slots.

When it comes to the Videoslots UK casino, they currently have over 6,200 games to pick from (at the time of writing). This encompasses not only online slots but also table games like Blackjack and Roulette, as well as their range of Live Casino games.

It’s an all-around casino site offering not only lots of real money casino games but also hourly Clash of Spins tournaments, Battle of Slots freerolls and even more tournaments as well as Exclusive Jackpots as part of their rewards program.

There are many advantages to playing at Videoslots casino online and mobile, including fast cashouts, live chat support, regular rewards and a range of deposit and withdrawal methods.

It’s not all rosy. Videoslots isn’t the easiest to navigate, they could do with a better search and filter function, especially with the number of games they have, and it doesn’t look as pretty as some others on the list of our best UK casinos.

But looks are only skin deep as this is one well-established UK casino website that offers more features than most you could pick from.

If you’re a fan of Microgaming slot machines, then there’s one casino that accepts UK players that can give you a great Microgaming experience.

That’s Grand Mondial Casino. It’s a true Microgaming casino site that, perhaps, doesn’t look pretty. Still, it gives you the full range of Microgaming games and its associated studios like Stormcraft Studios, Neon Valley and Just for the Win, to name a few.

You’ll find some exclusive slots you won’t find anywhere else, and they often have new games before any other casino. Not only that, but it’s a site that works on all devices.

Whether you’re visiting online or on your mobile, you can download the site or play instantly on games like Thunderstruck 2, Immortal Romance, Jungle Jim El Dorado, and all of the Mega Moolah jackpot slots that give you a chance to win millions.

With good customer support, a loyalty program and a site that just works, Grand Mondial casino is worth a look if you’re after a new UK Microgaming casino to play at.

LeoVegas casino, much like Videoslots, is a well-established casino site that offers an all-around gambling experience for UK players.

Their mobile casino has won awards due to its easy-to-navigate design and features.

You’ll be able to find a wide range of top casino software providers like IGT, NetEnt, Microgaming, Play’n GO, and Novomatic, giving you some old favourites and plenty of new slots weekly.

Regulated by the UK Gambling Commission, they adhere to strict rules and regulations to make your online gambling experience as safe as it can be.

With quick deposits and withdrawals, LeoVegas UK casino offers a generous welcome bonus for slots and live casinos.

An excellent instant-play casino. It just needs regular casino promotions in the UK.

4. Rizk Casino – best casino promotions

Rizk casino UK is one of those funny UK casino sites that has been around for years but doesn’t quite get the level of attention it deserves.

It’s a slots site with a great variety of games from NetEnt, Play’n GO, Red Tiger, Pragmatic Play, Quickspin, Relax Gaming, Push Gaming and more.

Rizk also boasts two exclusive slots in the Captain Rizk Megways slot and The Immortal Captain Rizk game.

Unlike the others on this casinos list, it has a casino loyalty program with a level-up system. The more you play for real money, the more you fill your progressive bar, which ultimately ends with a spin of the Wheel of Rizk, where you can get Free Spins with no wagering, bonus boosts, and more.

With regular promotions, as well as live casino games and sports betting in the UK, it’s a site that other popular casinos often overshadow. Still, much like the Jammin Jars slot, Rizk is a diamond in the rough.

5. Casumo Casino – best fun casino

Our last casino on our UK best casinos online list is a casino site that has been providing gambling services online for players worldwide, including the UK, for years.

Casumo casino UK lets you deposit and play in GBP while offering a few popular payment methods, including PayPal, Neteller, Paysafecard, and Visa and is one of the few Pay By Mobile Casinos.

They are also one of the best slot sites to play Playtech slots online. Yes, Videoslots and LeoVegas have some games, but you’ll find all of the popular Age of the Gods slots at Casumo.

But Casumo isn’t a one-trick pony. They also give you the best slots from Microgaming, NetEntertainment and Red Tiger Gaming, giving you a world of great low, medium and high variance slots with a range of features and win potential.

Add Reel Races slot tournaments, a loyalty program rewarding you with bonus spins, deposits bonuses and bonus money, along with exclusive Casumo Jackpots that you can win on popular slots like Book of Dead, and Starburst, and Casumo has plenty to offer UK slots players.
