What’s more, Grosvenor operates an extensive sportsbook, giving users the option to bet on football, cricket, tennis, boxing, horse racing, snooker, darts, and more. Besides the high number of betting options, the sportsbook offers competitive odds that are quick to update during live events.

As far as their welcome bonus is concerned, Grosvenor isn’t as generous as other sites. That being said, the online casino site makes up for that with a host of other bonuses, including daily free spins giveaways and a doubling bonus on initial sports bet.


4. PlayOJO: Top UK Casino for Fairness

  • Good selection of games
  • Payment options include PayPal & Neteller

Founded in 2017, PlayOJO is one of the newest online casinos on this list, and over the last several years, has carved out a reputation for doing things a bit differently than its competitors.

Unlike most other UK online casinos, PlayOJO doesn’t impose any wagering requirements or minimum withdrawal limits on bonus funds, something they term the ‘fairness approach.’

However, because of their dedication to fairness, their welcome bonus, albeit decent, is considerably smaller than most other online casino sites, which may deter some players.


5. Mansion Casino: Best Selection of Slots in the UK

What makes Mansion Casino really stand out is their larger than average welcome bonus, making it one of the more generous offerings available among UK online casino sites.

Leo Vegas

Beyond their customer service, Leo Vegas provides users with a variety of no-deposit bonus spins, excellent mobile support, and a sportsbook that includes horse racing, football, basketball, tennis and even eSports.

Unfortunately, there are several notable drawbacks to Leo Vegas which potential gamers should note. First off, unlike most gambling sites, Leo Vegas doesn’t offer video poker. Also, the number of progressive jackpots is very few.

That said, since the site is geared towards mobile players, the browser-based site on PC might be difficult to navigate.


8. Red King Casino: Top UK Casino Site for Progressive Jackpots

Redkings casino

  • 130+ progressive jackpots
  • 800+ games of slots

If a good selection of large progressive jackpots is what you’re after, Red King Casino won’t disappoint. As it stands, Red King has at least 130 different progressive games to choose from out of their catalogue of over 800 slots.

That being said, what the site lacks in variety it makes up for with a highly functional mobile app that provides a crisp user interface, 24/7 customer service, and access to many of your favourite casino games.

In conjunction with their quality mobile app (which is both iOS and Android friendly), Slots Heaven hosts 27 table games, 22 live casino options, and 21 payment methods, including PayPal and Bitcoin.

Lastly, while Slots Heaven does offer a welcome bonus, which we can tag as “okay.” However, it’s noticeably smaller than many of its competitors and they might need to step things up a notch here.
