We rundown every British casino based on reputation, licensing, game variety, and user-experience to give you the best UK casinos in 2021

If you prefer playing casino games online and don't know where to start, this review will point you towards the right casinos and all the information you need to know before beginning the gaming adventure.

Here’s our selection of the best online casinos in the UK, ranked based on their reputation, security, and bonuses. We also considered their game varieties and user experiences, which are impartial aspects of online gambling.

Our Checklist for the Best Online Casino Sites

Security - We have addressed important areas to ensure that the casinos we have listed have covered data encryption, fair gaming, and proper licensing.

Games Variety - Here, we went for numbers, diversity, and quality. The best casino sites should have a versatile range of games to suit all players, including those who want free trials and real money games. We also checked the state and reputation of software providers affiliated to these casinos. 

Bonuses - The leading casinos offer  bonuses that are realistic, and provide full disclosure concerning their bonus terms, especially the wagering requirements. 

User-experience - The overall experience from signing up to withdrawing funds should be smooth and convenient for every player. We take customer experience seriously and always take into account their overall experience in every casino we feature.

The Best UK Casino Sites in Detail

1. PlayOJO - Best Bonus Terms

HeraldScotland:

No wagering requirements on bonuses

Cashback on bingo and casino games

Available in iOS and android

PlayOJO covers some very crucial bases of online casino gaming. It stands out for the wager free requirements on all bonuses, doesn't have withdrawal restrictions, and the casino doesn't put a cap on wins.

The game variety isn't strained either, considering the top software providers in its camp. Even though slots are the majority, the table game lovers are in for a fun-filled adventure. We commend the casino for the laxed bonus terms but still feel the 50 free spins welcome bonus is so low that it doesn't even meet market requirements. 

2. The Sun Vegas - Best Roulette Games

HeraldScotland:

Several quality slot games

Generous welcome offer

Quality roulette games

This is yet another A-lister casino in our compilation. Sun Vegas has a versatile selection of top-tier slots, a state-of-the-art mobile casino, and knowledgeable customer support. It's the best UK online casino for Roulette with the 3D games available.

The deposit and withdrawal channels are convenient for UK players. It may not be a long-serving site, but we have faith in it since it’s properly licensed and audited. The casino has a modern website and a customised mobile app. On the flip side, the website can be annoyingly unresponsive, which is such a deal-breaker.

3. Magic Red - Best Slot Games

HeraldScotland:

Generous welcome bonus

Flexible payment methods

Excellent mobile casino

Magic Red starts you off with its large list of games, then the variety will have you alternate between the numerous slots and table games. There’s a good selection for each casino game category from leading software providers like NetEnt, MGM, and more.

The live casino also has an extensive complement of virtual games, including the 3D ones with crisp themes and several bonus features. The deposit and withdrawal methods are equally convenient for all UK players. On the downside, though, it only has live poker games but no video poker.

4. Grosvenor - Best Longest Serving Casino

HeraldScotland:

Convenient payment methods

Highly reputable casino

Great mobile casino

If there's a casino that stands out for its stellar reputation and agility in the gambling industry, then it’s Grosvenor. The IGT powered casino has been around long before the Internet was a thing. Aside from its land-based performance, the online platform is just as thrilling.

The online casino site has some good bonuses to start you off. But there’s also something for the existing players. Various jackpots, giveaways, VIP program rewards and more are there to help retain players. There's no room for boredom at Grosvernor, with their diversified games, including a sportsbook.

For a casino held with such high regard, we feel the welcome bonus is quite small. 

5. Genesis Casino - Best Casino Table Games

HeraldScotland:

Fast payouts

Great game variety

Handsome welcome bonus

Genesis Casino, though still taking baby steps in the igambling industry, has quite a bright future, should it keep up its services. The number and variety of games at the casino are worth noting. While most casinos stuff video slots but starve the other categories, Genesis casino has a good number of video poker, roulette, baccarat, and blackjack.

The promotions here aren't bad, neither are they few. There's a good welcome bonus, daily and weekly prizes, free spins, cashback, and more. We didn't quite capture the loyalty bonus though. 

6. Mansion Casino - Best Jackpot Games

HeraldScotland:

Quality game variety

Mobile-friendly casino

Convenient payment methods

Why Mansion Casino, you ask? It made it to our top ten best online casinos in the UK for various reasons. The Playtech casino has lots of great slots and other games. There’s also over  300+ jackpot games for high-spirited players and an award-winning live casino. It has a good user interface and several online casino bonuses and promotions too.

The games load fast, unlike the usual lags from other online casinos we've witnessed. Yes, it has a mobile app for android and iOS users. The withdrawal process takes a bit longer, but you expect payments within 5 days once it's done.

7. Leo Vegas - Best Mobile App

HeraldScotland:

Top live casino experience

Virtual sports available

Regular game updates

If you are just new to the online gaming scene, Leo Vegas is a great place to start. The casino starts you off with a no welcome deposit bonus, then more offers to ensue. With over 650 slots from NetEnt Gaming, Red Tiger Gaming, and Microgaming, the online casino site  prides itself in being the best live casino and slots centre. 

Does the casino size down to mobile devices? Yes. The customized award-winning mobile version has a great game variety, too. Leo Vegas assures players of top-tier entertainment at their fingertips.

The casino has few but reliable payment methods. We’d like to see more options soon, including cryptocurrencies.

8. SlotsHeaven - Most Organised User Interface

HeraldScotland:

Quality progressive slots

Compatible with all devices

Good user interface

SlotsHeaven, at a glance, has a neat layout with every important icon within visibility. As you scroll further, it provides all the necessary information to the dot. The casino site has hundreds of exciting video slots, table games, classic slots, and live dealer games. 

The slots are categorised even further so that players can identify what they want without sweating it. There are categories based on themes like fruits, animals, Aztec, and adventure slots. With software providers like Playtech, Skywing, and Eyecon, the game selection is epic.

The first deposit bonus is generous enough, and the casino offers reload bonuses, table game bonuses, and more free spins on selected games as well. Should you hang around long enough, great VIP perks await. Generally, SlotsHeaven has achieved the major hits of a casino. However, they could still use more games in their portfolio.

9. Red Kings Casino - Best Game Variety

HeraldScotland:

Attractive bonuses

Fantastic jackpot games

Top software providers

Red Kings Casino is a licensed online gambling site with an endless list of quality games.  It's the best online casino for real gaming experience considering the 3,000 games from over 50 software providers. The online casino site offers players welcome bonus, daily tournaments, and a VIP lounge for loyal members. 

Even though the welcome offer is better than nothing, we've seen better.

You can access the website on any gaming device, but they currently do not have a casino app.

10. BacanaPlay - Best Free Spins Offer

HeraldScotland:

3,000+ games

Interactive live dealer casino

Regular tournaments

Whether it's a movie-themed or Vegas-style slot you are looking for, BacanaPlay has 2,800+ titles, including the latest ones from top-notch providers like WMS, NetEnt, and Microgaming to choose from. The casino has also stacked many card games, roulette, jackpot games, and detailed live casino games.

After the welcome bonus depletes, the casino still has daily picks, discounted spin packages, prize twister, and tournaments. However, it's the free spins for a year that caught our attention. With just a single deposit, you can get a free spins offer that lasts a year. 

There are a few payment methods, and you can only withdraw through bank transfer, which is a tad long and inconvenient.
