About Grosvenor Casino

Grosvenor may be better known for their brick and mortar casinos found in town centres up and down the country, but actually, they’ve had an online presence for over a decade. However, the online casino had a bit of a stuffy, old fashioned reputation that seemed at odds with what our players tend to enjoy.

Grosvenor Casinos has had a nice refurbishment and our friends at the Rank Group have had a good old go at sprucing it up. What’s more they’ve really jazzed up the welcome bonus. For all these reasons, we’re listing it on WDW Bingo for the first time.

Grosvenor Casinos was founded all the way back in 1970 with the slightly less glamorous name of “County Clubs” which then became “Grosvenor Clubs.” Now, there are over 50 Grosvenor Casinos in the UK including the London Victoria casino which even has its own online casino, The Vic.

For a fifty year old national institution, they sure have scrubbed up well. This is a completely modern, mobile-ready slots site with a whole lot of heritage to back it up.

Welcome Bonus & Promotions

The welcome package at Grosvenor Casinos is greatly improved with the opportunity for a big match bonus buy-in.

Just as impressive though is the constant stream of ongoing promotions. Head over to the promos page and you’ll see they have frequently over 15 active promotions at any given time spanning slots, jackpots, live dealer and even sportsbook.

There’s also a membership programme which includes perks like the ability to transfer your balance from online to bricks and mortar, or vice versa.

Slots & Games

Grosvenor Casinos is very well kitted out in terms of slots and games content. There are hundreds of slots from a variety of providers including new slots like:

  • Bigger Bass Bonanza
  • Dynamite Riches Megaways
  • Book of Ra Cash Connection
  • Treasure Mine Power Reels
  • 4 Diamond Blues Megaways

There is also an excellent live casino provision including a handful of exclusive Grosvenor live tables and even some live game show style games.

As we mentioned, there is also sports betting if that’s your thing.

Final Thoughts

Grosvenor Casinos gets a big thumbs up from us for their greatly improved online slots site. The exclusive welcome bonus is fantastic and there is a myriad of gaming content to enjoy including slots, live dealer and sportsbook. This site also has one of the most impressive selection of active promotions we’ve ever seen.
