Grosvenor Casino Review

Grosvenor Casino is the official online gaming site of the UK's largest land-based casino operator. Grosvenor operates over 50 casinos around the UK and also runs a sportsbook and poker room online.

The online casino itself is Flash-powered and games can be accessed through an instant-play client through your web browser. Many of the games are exclusive to Grosvenor, including some live dealer variants streamed direct from UK real money casinos.

Operated by UK's biggest land-based casino giant Website looks dated compared to rivals

Welcome Bonus

Grosvenor Casino is offering a simple welcome bonus to new players. Sign up and deposit at least £20 and you will receive £20 in bonus cash up to a maximum of £250.

To withdraw the bonus and any winnings, you must wager the bonus amount 25x. General terms apply, but most slots contribute 100% towards the bonus total.

Other promotions: You can claim a £30 bonus to use at Grosvenor online casino when you sign up to the new Grosvenor One account.

Elsewhere, there are regular Game of the Week promos featuring free money on selected slots. Weekly giveaways give you the chance to win £1,000 cash or Bonus Plus rewards whenever you play table games and slots.

Grosvenor's Black Card is a VIP privilege that can be used online or in-casino. You receive enhanced Play Points every time you gamble and get access to a personal account manager. You will also receive exclusive in-casino promotions, which is perfect if you live near a Grosvenor casino.

For an ageing site in need of a revamp, Grosvenor's online registration process is fairly simple. You can register an account without downloading software, and you will need a valid home address to get started.

To adhere to UK Gambling Commission laws, online casinos are required to verify customers' ID and age. Grosvenor Casino takes its verification process seriously.

You will need to send a scan of your ID and a recent utility bill in order to action any withdrawal. We found that process to be pretty smooth, and the live chat staff were able to accept uploaded documents too.

Payments and Banking Methods

Grosvenor Casino supports banking via the usual major debit cards. You can set a deposit amount from £10-£100, but there is a minimum limit of £5 available.

When you open an account, you can also sign up to Grosvenor One. Grosvenor One is an all-in-one wallet that allows you to make deposits online or in-casino at any Grosvenor in the UK.

You can also use your Grosvenor One account to cash out winnings in any land-based Grosvenor casino. Alternatively, you can use your Grosvenor One card to spend on land-based slot machines or electronic roulette. Even better, you can claim a £30 no-deposit bonus when you become a Grosvenor One member.

Withdrawals can be made to an e-Wallet or debit card. There is a minimum cash-out amount of £10, but you can usually withdraw your entire bankroll if you have under £10. Cash-outs take 1-5 business days. Bank transfer fees may apply so always check first.

You can make withdrawals to your bank account but have a recent bank statement handy to send the verification team.

Desktop/Mobile Experience

First, the bad news: Grosvenor Casino's online casino is starting to look very dated, particularly when you compare it to newer online casinos. However, at time of review Grosvenor were loudly promising on their homepage that a revamped casino client was on its way.

You can access demo play and real money slots and games through your browser without downloading. However, you can download the Grosvenor Poker app to your PC desktop and access some casino games that way.

In practice, we actually recommend sticking with the instant-play casino. It has more games, a better interface, and you can set your preferences a lot easier.

To get started, just log in via the Grosvenor Casino webpage. You can also now log in using your Grosvenor Casino membership number if you have visited a UK Grosvenor casino.

Grosvenor Casino provides a simple instant-play mobile site for its customers. There is no need to download any apps and you can access your account via a mobile browser.

The mobile lobby at Grosvenor Casino is simple to navigate and there's a handy shortcut menu that can be hidden away on the left-hand side. One downside is that you can't seem to view the lobby in landscape mode, at least not on smaller portable devices.

Titles are grouped into Slots and Games, Live Casino, Table and Card, and Jackpot games. You can also access Grosvenor's sportsbetting markets via your casino account, or play online poker.

There are over 150 slots for mobile, including a good selection of jackpot games like Mega Moolah and MegaJackpots Wheel of Fortune.

Game Variety at Grosvenor Casino

There are over 250 games at Grosvenor Casino. Admittedly, the selection is dominated by online slots, but you can also play table games like roulette and blackjack. There is also a live casino powered by Evolution Gaming.

Games are divided into categories in the lobby (slots, jackpot titles, table & card games, etc), and the Jackpots tab is particularly well-signposted. The tab contains the list of Top Jackpots that day, Daily Jackpot titles, and Grosvenor's well-stocked list of MegaJackpots games from IGT.

Grosvenor Casino has over 200 of the latest online slots available. You can play for demo money or try your hand with some real cash. It's good to see online casinos still providing demo play versions of their most popular titles, and Grosvenor Casino doesn't disappoint.

Slots are divided into categories in the desktop client. You can sort by Featured games, new games, and slot machines you will find in your local land-based Grosvenor casino. Annoyingly, you can't filter the slots lobby by developer but there is a handy search box to get to your favourite games fast.

Grosvenor casinos around the UK are known for their Novomatic and IGT slots, particularly popular Gaminator titles like Book of Ra and Lucky Lady's Charm Deluxe. You can play those Novomatic games online at stakes much lower than you will find in a land-based Grosvenor. You can expect to find plenty of good Microgaming slots on the site too like Mega Moolah.

The highlight of the Grosvenor slots lobby is the jackpot games list. Daily Jackpot games award must-win jackpots every day. There are also several 'Must-Go' jackpot slots where the top prize is won before a fixed cash amount has been wagered. Blueprint Gaming's Jackpot King range offer multiple games and multiple 'must win' jackpots.

There are over 20 table game variants at Grosvenor Casino. The selection is dominated by roulette and blackjack, however, and there is little in the way of alternative games like Craps or Ultimate Hold'em.

However, the range of roulette and blackjack is very good and most games can be played for demo money or real cash. You will need Adobe Flash Player installed to operate some games.

As with the online slots, there are full details and rules on every game, together with an RTP (Return to Player percentage).

Roulette: 16 roulette variants are available at Grosvenor Casino. Player's Suite Roulette is an IGT variant with advanced betting for the more serious gamblers. At the lower end of the spectrum you will find fun European Roulette variants like 10p Roulette and 20p Roulette with low minimum stakes.

Blackjack: There are 12 blackjack variations at Grosvenor, but the lobby is dominated by live blackjack games. Look out for Flash-powered games like Openbet's Classic Blackjack with exclusive Grosvenor branding. The graphics aren't great but the gameplay is simple and you can play from as little as £1.00 a hand.

Other games: Grosvenor online casino scores a little lower on alternative games. There's not a lot in the way of video poker save a Jacks or Better variant from OpenBet. Bets range from £0.25 to £30 a hand, and you can win up to £100,000.

3-Card Brag, also from OpenBet, is a fun little variation to try. It has a top bonus payout of 333/1 if you hit the highest prial.

Betting Limits

The best online casinos provide clear information on minimum and maximum stakes, as well as max payouts. Every single game at Grosvenor Casino has detailed information and rules. You will also find RTPs for many games.

The minimum stakes on slots is £0.01 and most jackpot games allow bets up to £1,200 a spin. While there isn't a running list of jackpot winners on the site, Grosvenor Casino does boast paying out over £1m in 2018 alone.

There is no dedicated VIP gaming section at Grosvenor Casino. However, most live casino games allow bets up to £10,000.

Return to Player Percentage

Every online casino guarantees audited and regularly checked RTPs (Return to Player percentages) on their games. Grosvenor Casino lists RTPs for all slots and table games so you can gauge which have the best long-term payouts.

Blackjack games at Grosvenor offer the best theoretical returns, but the RTPs for roulette games varies wildly.

Customer Support

Grosvenor Casino offers a wide range of customer service options. The support is excellent and the staff dealt with our queries swiftly.

Phone support is available from 8am, but live chat is open 24/7. Even the email support service was quick, and we didn't have to wait a day to receive a response.

There is also a detailed FAQ page on the Grosvenor Casino site which answers popular queries on account and technical issues, promotions, and deposits.

Responsible Gambling Features

As a UK-licensed site, and the UK's largest casino chain, Grosvenor takes its responsible gambling duties seriously. As soon as you register you can set daily, weekly or monthly deposit limits. Limits take 24 hours to take effect. You can also reverse any pending withdrawals you might have on the site.

As well as setting limits, you can ask to receive a Reality Check - a reminder on how long your gaming sessions are and how much you are betting. The 'Take a Break' function lets you program a scheduled temporary break from a day to six weeks.

In addition, you can choose to be self-excluded from the online casino. On your account, you also have the option to self-exclude from all Grosvenor land-based casinos too.

Our Verdict

You would expect to find a online casino from the UK's oldest land-based chain. That's exactly what you get at Grosvenor Casino. The site is functional, and the mobile client is easy to use. And if you are a slots fan, you will love the range of in-casino titles and progressive jackpots.

The biggest downside is the lobby at Grosvenor Casino. It is certainly showing signs of age, but with promises of newly-designed site coming, this could be just the right time to sign up and open an account.
